Introduction  
DVST is the generic name for a range of products designed to store and transmit digital  
pictures at a higher quality and speed than previously possible.  
1.1  
1.2  
1.3  
DFT-0150 Transmitter  
The DFT-0150 (Digital Fast Transmission) transmitter will process the images from up  
to sixteen cameras for transmission or reception over ISDN or PSTN telephone lines.  
Telemetry  
The DFT 0150 can control telemetry cameras at the local site using built in telemetry  
equipment.  
Event monitoring (Alarms)  
The internal alarm verification system for DFT0150 transmitter allows the unit to monitor  
and act on external events. This can freeze a picture from the camera that corresponds  
to a specific alarm input. The unit will then transmit this picture to the receiving station  
where the operator can acknowledge the event and take relevant action.  
This versatile alarm interface is a light duty 16 input / 2 output unit.  
1.4  
Audio option  
Audio transmission is available allowing two way, half duplex, (one way at a time)  
communication. (Transmission medium must be 19200baud or faster)

Operation  
3.1  
Callback  
The callback feature allows an operator at a monitoring station to call a DFT0100  
transmitter on site and configure the unit to automatically call them back, ensuring that  
the telephone call is charged to the transmitting and not the receiving site.  
On sending a callback request, the monitoring station disconnects and waits for the  
transmitting site to call back. With callback enabled, connection time is approximately  
twice that of normal connection time.  
3.2  
Alarms Feature  
The alarm system for the DFT0150 transmitter allows the unit to freeze the pictures from  
cameras that correspond with the alarm inputs that have been triggered. These pictures  
are then transmitted to a receiving station where they can be acknowledged and the  
relevant action taken.  
On an alarm the transmitter will automatically call the telephone number stored in  
telephone entry 0.  
If this number is busy then it will call the number stored in telephone entry 1. The  
maximum number of telephone entries can be set between 1 and 16.  
If the fall back numbers are busy the transmitter will automatically keep calling between  
telephone entries 0 and 1 until one becomes free. However the user can configure the  
DFT0150 to automatically call upto four numbers unitl one becomes free.  
Depending on how the transmitter has been configured, incoming alarms are handled in  
different ways.

Operation  
DVST InstallationGuide  
3.3  
Freeze All Alarms  
Each alarm activation stores the corresponding camera image and transmits the frozen  
image to the receiver.  
The frozen pictures with a record of the time, date and camera number will be stored in  
memory until the alarms have been acknowledged.  
3.4  
No Frozen Images  
No frozen images are sent on alarm. If several alarms ocour to trigger the machine to  
dial, one shot from each will be sent in quick successionwithout any operator control.  
Any alarms present whilst on line will be indicated on the receive unit display baseline.  
3.5  
3.6  
Offline Frozen Alarm  
The first alarm activation stores the corresponding camera image and transmits the  
frozen image to the receiver.  
Track Last Alarm  
With this mode no frozen images are sent.  
If several alarms ocour to trigger the machine to dial, one shot from each alarm will be  
sent in quick succession without any operator control, following an intruder. Any alarms  
present whilst on line will be displayed full screen and un frozen.

PSTN Connection (Modem)  
Connection to a PSTN telephone line is via a modem and modem port.  
MODEM Commands  
MODEM=  
Sets MODEM operation, three parameters:  
The MODEM= command controls three distinct parameters.  
OFF  
(default, OFF)  
Tech note: The reason is as follows; if set to ATMODE the DVST attempts to communicate with the  
MODEM when starting up, exiting set up mode etc. The DVST will wait a set period of  
time for replies before giving up. This will considerably slow the system if no MODEM is  
attached.  
DIRECT, ATMODE  
(default, ATMODE)  
The DIRECT mode is used if the MODEM has its telephone numbers  
stored internally and the DVST does not pass telephone numbers for  
dialling.  
The ATMODE is most often used. The DVST passes numbers from  
the dial menu to the MODEM which then initiates a call.

DVST InstallationGuide  
SYNC  
The sync or synchronous mode relies on the modem generating clock  
signals to the DVST.  
MODEM  
Modem switches from the command mode CMD> to allow direct  
control of a connected MODEM. The speed of communication with the  
MODEM will be as set with the MBAUD= command.  
This is called transparent MODEM mode and is terminated by  
pressing the ESCAPE or ESC key.  
MBAUD=  
Set MODEM port ASYNC baud rate.  
(default, 19200)  
9600, 19200, 38400  
This command sets the speed of communication between the DVST  
and the MODEM when AUX 1 is used for asynchronous mode. The  
speed of communication in the Synchronous mode is determined by  
the clock signal supplied by the MODEM.  
ASYNC  
In the asynchronous mode the MODEM controls the flow of data using  
RTS/CTS signals.  
MODEM2  
PORT=  
Modem switches from the command mode CMD> to allow direct  
control of a connected MODEM through AUX 1. The speed of  
communication with the MODEM will be as set with the PORT=  
command.  
This is called transparent MODEM mode and is terminated by  
pressing the ESCAPE or ESC key.

Modem configuration strings  
All MODEMs need special configuration, depending on how the MODEM is to be used  
and how the DVST will interact with it.  
Standard MODSTR set ups configure the MINIT and SREG strings, the USER string is  
left free for any extra configuration that may be needed.  
MODSTR=  
Set type of modem: FAST or SYNC  
(default, FAST)  
This setting (shortened form of MODem STRings) automatically sets  
up the DVST to operate with one of the three recommended  
MODEMs.  
FAST  
This sets the MINIT and SREG strings for correct synchronous  
operation with the MOTOROLA 326x VFAST MODEM. The MODEM  
configuration strings are set up as follows:  
MINIT=AT&M1 &D2 &C1 *FLO *AA1 *DTO *OC1  
SREG=ATS10=30S25=0  
SYNC  
This sets the MINIT and SREG strings for correct synchronous  
operation with the MICROCOM 4232bis MODEM. The MODEM  
configuration strings are set up as follows:

ZYXEL (US Modems Only)  
This sets M2INIT and SREG2 for the correct synchronous operation  
with the ZYXEL modem. The modem configuration strings are set up  
as follows:  
M2INIT=AT&M1&D2&C1&H0  
SREG2=ATS10=30 S0=1

SEND  
Available for user configuration  
(Default, blank)  
The USER string is for any extra commands that the user may need to  
send to the modem in addition to the MINIT and SREG settings.  
Send current modem configuration  
This transmits the information contained in the MINIT, SREG and  
USER strings to the MODEM.  
Although this command can be issued from the command mode at any  
time, it is also invoked at the termination of any call and when the  
command mode is exited with the QUIT command.

Modems  
DIAL=  
Modem dial string  
(default, ATDT)  
This is the command that must precede all numbers that the MODEM  
has to dial. Typically the MODEM will dial using either pulse or tone  
dialling. This is dependent on the telephone exchange the MODEM is  
connected to, most modern exchanges are able to accept tone dialling  
which is faster than the older pulse dialling method.  
For tone dialling: DIAL=ATDT  
For pulse dialling: DIAL=ATDP  
Tip:  
Extra information can be linked to the above commands, internal exchanges that  
require a “9" to be dialled to access outside lines can have this added to the dial string,  
typically ATDT9.  
7.4  
Modem Operation  
All modern modems respond to a set of “Hayes” commands. There are several  
differences in these commands from manufacturer to manufacturer. It is important to  
use the correct commands with each modem and not to attempt to use one  
manufacturer’s set up with another manufacturer’s modem.  
If possible modems should be linked to DVST in the synchronous mode. Some  
modems, for example those using PEP (Packet Ensemble Protocol), can only be used  
in the asynchronous mode.  
Cables for connection to synchronous and asynchronous modems are different and are  
not interchangeable. Refer to the Cable Assemblies chapter for further details.

7.5  
Connecting a modem in direct mode  
This mode uses a modem in a ‘dumb’ mode, and purely relies on the hardware control  
lines. Telephone number selection, and all other configuration must be performed at the  
modem.  
The modem is controlled using DTR (Data Terminal Ready), and indicates it’s status  
using DCD (Data Carrier Detect).  
Note:  
This mode is not recommended, easier operation is achieved in ATMODE.  
Call request  
A call is requested by making DTR active (high). At this point the MODEM dials it’s  
stored number, and attempts to establish the call with the remote end. When the call  
connect has been completed the modem raises it’s DCD line, confirming it is connected  
with the remote location.  
A call already being active is indicated by the DCD line being active (high) from the  
MODEM.  
Call answer request  
If a call is incoming, the modem answers the call, establishes the physical link, and then  
raises DCD to inform the DVST unit that a call is present. The DVST unit responds to this  
by taking DTR active (high).  
Call disconnect.  
This is requested by dropping the DTR signal. A successful disconnect is confirmed by  
the DCD line being dropped by the MODEM. In this mode the DTR line remains low.  
Configuration of modem in direct mode  
No configuration can be performed by the system, however the following are required of  
the modem :  
Select synchronous operation.  
Dial stored number on low to high transition of DTR.  
Disconnect on a high to low transition of DTR.  
DCD must follow remote carrier.  
Ignore DTR to answer.  
Auto-answer. ( If required ).  
No flow control enabled.  
Page 22  
Dedicated Micros Ltd  
 
DVST InstallationGuide  
Modems  
7.6  
Using a modem in ATMODE  
In this mode the Hayes set of commandsis used, all of which begin with the letters AT.  
Both call setup and configuration are performed using these commands.  
The commands can be configured on the DVST unit in setup mode.  
The modem is also controlled using DTR (Data Terminal Ready), and indicates it’s  
status using DCD (Data Carrier Detect).  
Call request  
The DTR is normally active, unless the modem channel is turned off, or the unit is in  
setup mode.  
To dial a call the system sends the dial string (set by DIAL= in the DVST setup menu ) to  
the modem, followed by the number selected.  
For synchronous operation the modem switches to synchronous mode on connection.  
When the call connect has been completed the modem raises it’s DCD line, confirming it  
is connected with the remote location. A call already being active is indicated by the  
DCD line being active (high) from the modem.  
Call answer request  
If a call is incoming, and the DTR line is high, the modem answers the call, establishes  
the physical link, and then raises DCD to inform the DVST unit that a call is present.  
Call disconnect  
This is requested by a high to low transition on DTR. A successful  
disconnect is confirmed by the DCD line being dropped by the modem.  
In this mode the DTR returns high after a short delay.  
7.7  
General settings for modems in ATMODE  
The modem is configured from the DVST unit using the following strings:  
MINIT=general modem configuration.  
SREG=typically used for setting of s-registers.  
USER=optional string, typically for individual customisation.  
DIAL=string used to dial, typically ATDT for tone dialling.  
The configuration details stored in MINIT, SREG & USER are sent on power-up, leaving  
setup mode, and on disconnecting a call. If a MODEM is not present a large delay will be  
experienced while the system waits for replies from the MODEM. To avoid this the  
command MODEM=OFF should be selected from the DVST setup menu. It is also  
possible to transmit or send these values to the MODEM using the SEND command in  
setup.  
It is also possible to communicate with the modem directly using the MODEM  
command.

MODEM Requirements  
Although there are default settings for three MODEMs, other MODEMs can be  
cofigured to operate with DVST.  
As the settings vary from manufacturer to manufacturer there is not a set series of  
commands that are guaranteed to work. The following tables detail possible  
configurations, all should be checked against the MODEM manual. Before attempting  
these suggested settings the MODEM should be reset to factory defaults with the  
command AT&F or ATZ  
The following settings are required as a minimum:  
All modems:  
Action required of MODEM  
Possible AT settings  
DCD (Data Carrier Detect, sometimes abbreviated to  
CD) must be set to follow the carrier. This signal  
indicates to the DVST that a connection to another unit  
has taken place.  
&C1  
The call must disconnect on a high to low transition of  
DTR (Data Terminal Ready).  
Only answer a call if DTR is present.  
&D2  
Auto-answer may be set if required.  
S0=1  
Check MODEM manual  
Country specific  
Echo commands.  
E1  
Synchronous Modems:  
Extra action required of Synchronous MODEM  
Possible AT settings  
Asynchronous mode must be set to dial the number  
and the modem must switch to synchronous mode on  
carrier detect.  
&M1  
Flow control must be disabled.  
&K0  
Check MODEM manual  
The modem should ignore RTS.  
&R1  
Asynchronous Modems:  
Extra action required of Asynchronous MODEM  
Possible AT settings  
Asynchronous mode must be enabled.  
Flow control must be enabled on RTS/CTS.  
Error correction enabled ( if needed ).  
&M0  
&K3  
Refer to MODEM manual  
Note  
It is strongly recommended that once the modem has been configured as above, it is set  
in such a mode that this configuration is recalled automatically on power up. This will  
help to ensure correct operation after a power failure. Consult you modem instructions  
for details of how to achieve this.

MOTOROLA VFAST  
Cable required to connect to DVST: (25 to 25 - V24 SYNC)  
When installing the VFAST MODEM the following procedure should be  
followed:  
Connect the MODEM and DVST as in the installation chapter.  
Power up the DVST (leave the MODEM without power).  
Enter the setup mode and configure the DVST for operation with the VFAST MODEM by  
typing the command MODEM=ATMODE,MODSTR=FAST (default setting).  
Power up the MODEM and wait for the self test to finish.  
Type SEND then <ENTER>.  
The DVST will program the MODEM.  
It is good practice to store these values permanently in the MODEM.  
Then the values will not be lost if power is removed from the MODEM.  
To store these values proceed as follows:  
User= AT&Y1&W1 <return>  
Send <return>  
Moden displays <save completed>  
The MODEM will then always power up with the correct operational configuration.  
Country specific settings  
The answer on number of rings command *AA1 is not valid in some countries (France,  
xx) and the MINIT string should be reprogrammed with the value *AA2.  
The MINIT string is programmed as:  
MINIT=AT&M1 &D2 &C1 *FLO *OC1 *DTO *DE12 *AA1  
Dedicated Micros Ltd

Modems  
DVST InstallationGuide  
No Dialtone  
In some cases the MODEM will not recognise the prescence of a dial tone from the  
exchange. The following codes will allow blind dialling and if these are needed  
permanently they should be followed by:  
User=ATX3*BDO&Y1&W1  
Where  
ATX3 is Dial blind without presence of dial tone  
*BD0 Wait two seconds before dialling  
&W1 Store above settings in option 1  
&W1 Power up using these settings  
Note:  
This feature is country specific and may not be available in some versions of the  
MODEM’s software. Please refer to the literature supplied with your MODEM.  
Transmission speed  
The MODEM can be a little ambitious in setting the line speed. It is likely that a link will be  
established at a higher speed than the line can support without an unacceptable level of  
errors.  
In these cases it may be necessary to limit the speed of transmission until a reliable point  
is reached.  
Maximum line speed may be set by the command:  
AT*MXn  
where the value for n equals following baud rate applies:  
13 =28800  
12 =26400  
11 =24000  
10 =21600  
9 =19,200  
8 =16,800  
7 =14,400  
6 =12,000  
5 =9,600  
4 =7,200  
3 =4,800  
2 =2,400  
1 =1,200  
0 =300  
To limit the speed of transmission to 14,400 use AT*MX7. This could be stored in the  
USER= string.

Leased Line Transmission  
9
Leased Line Transmission  
Leased line transmission is generally used when a dedicated or private line is available  
to connect the transmit and receive units.  
There are many different types of leased line, 2 wire and 4 wire, with many variants  
depending on what is offered by the PTT companies.  
Most conventional Modems can operate on leased lines although the cables will differ  
from those used on a standard telephone connection.  
Baseband Modems offer faster transmission rates over standard Modems and an  
example using one of these is given at the end of this chapter.  
9.1  
9.2  
Leased line terminology  
In leased line terms the receiver or calling unit is set as ORIGINATE.  
The transmit unit is set to ANSWER.  
DVST set up for leased line operation  
When leased line operation is selected, the type of transmission selected (via the X21 or  
the V24 port) is determined by the dial type set in telephone number 0.  
If telephone number 0 is set to MODEM, the V24 or Modem port will be used. If either  
ISDN 0 or 1 is specified, X21 ports 0 or 1 will be used.  
LEASED=  
Leased line operation, options are:  
(default, OFF)

Leased Line Transmission  
DVST InstallationGuide  
ORIGINATE  
The Receiver unit is set to originate.  
ANSWER  
The Transmitter unit is set to answer.  
OFF  
This disables the leased line feature.  
9.3  
Leased line operation  
When leased line operation has been set up, the DVST will attempt to communicate with  
a remote site when clocks are received. This does not require hardwarehandshaking.  
If the line is broken for any reason, the units will attempt to reconnect and when  
commuunicationis restored will automaticallyestablish video transmissionof images.  
The units can be disconnected (taken off line) by pressing the LINE key. Pressing the  
LINE key again will establish image transmission.

ASCOM 64000 Baseband Modem  
The am-64000 is a good alternative to using a conventional PSTN MODEM in leased  
line mode.it also has a greater data transfer rate for short or private wire connections,  
the speed is 64kbps for the AM-64000 and 128kbps for the AM-128000, the max  
distance between the two units is 14 kilometres on a 0.64 mm cable or a -50 db loss.  
Set Both Dvst Units In The Direct Mode  
Using the cursor keys on the front of the ASCOM unit set the system up as follows.

10.1  
Passwords  
Passwords can be set and used by the system. When a PASSWORD is set it provides  
protection for the system at two points:  
1) Whenever a remote system calls it must send the correct password, otherwise  
no connection will be established.  
2) Whenever the SETUP key is pressed, the password will be requested before  
the setup mode is entered.  
Method:  
Enter SETUP mode is by pressing the SETUP key on either keyboard.  
If a password has been set the screen will go blank and the prompt PASSWORD  
will appear on the screen. At this point a valid password must be entered followed  
by pressing the <ENTER> key. If this entered correctly the prompt CMD will  
appear on screen.  
PASSWORD= Set system password to ...  
The system password can be up to 10 alpha numeric, case sensitive,  
characters. Once this has been set only calling units that have the  
associated password linked to the telephone number can access the  
system.  
PASSn=  
Set telephone entry n password to ...  
Range is 0 to 19  
This is linked to the designated telephone number and is the keyword  
that will unlock the remote system that is being called. It may be up to  
10 alpha characters in length.  
Format: PASS4=BERLIN  
In the above case the system called would have the password set to  
BERLIN. Only then could the system be accessed.  
Default: None set  
Dedicated Micros Ltd  
Page 43  
 
Calls  
DVST InstallationGuide  
SPASSWORD= Set SETUP password to ...  
This feature allows an additional password to be allocated just to  
provide security for the set up mode. This can be used to prevent a  
remote user accessing the system and altering the settings.  
Default: None set  
Note:  
To maintain security, passwords cannot be read back from the system. Care should be  
taken to ensure passwords are not lost as this will require a new EEPROM chip to be  
fitted to the DVST.  
10.2  
On Screen Titling  
SYSTEM=  
Set system ID string to ...  
This is a 30 character title which appears on the front screen of the  
DVST. When a transmitter sends to a receiver this title is transferred  
from the transmitter and appears on the baseline of the receiving  
monitor.  
TIME=  
Set current time in HHMM format  
The time is based on the 24 hour clock. 4 digits must be entered.  
DATE=  
Set current date in DDMMYY format  
Date is always set as a six figure format.  
Two optional messages are superimposed on camera images sent from the transmitter.  
The first is the camera title and the second is the time and date.  
TLPOS=  
Set camera title position  
(default, 1)  
When the images are transmitted the camera title appears at the top of  
the screen. This setting adjusts the height of the camera title.  
TDPOS=  
Set clock screen position  
(default, 11)  
When the images are transmitted the time & date appears at the  
bottom of the screen. This setting adjusts the height of the time & date  
information.  
Note:  
The range available for both TLPOS and TDPOS is from 1 to 11, 1 is at the top of the  
screen and 11 at the bottom. Settings for TLPOS and TDPOS should be 2 numbers  
apart to avoid overlap. Setting either value to 0 removes the text from the screen.

10.3  
Telephone Number Entries / Connection Commands  
TELn=  
Set telephone entry n to ...  
(default, blank)  
Twenty telephone numbers can be stored in memory.  
Format: TEL2=01044617944965  
If the MODEM or ISDN Terminal Adapter is to work in the DIRECT  
mode, the entry can be left blank.  
Telephone number 0 is the default number dialled when alarms are  
used to initiate a call to another system. The fall back number if this is  
engaged is always stored in telephone number 1.  
Where a number is used with dual ISDN dialling it is automatically linked with that  
number plus 10. Therefore Tel number 4 & 14 would be dialled if dual ISDN was  
selected for that telephone number.  
TELn  
Set telephone entry n as current  
This selects the number that will be dialled initially if the up/down keys  
are not used to select another.  
Format: TEL2  
TYPEn=  
Set telephone entry type to dial via ISDN0, ISDN1,  
ISDNx2 (dual), or MODEM  
(default, ISDN0)  
Each of the telephone numbers can be linked to either a PSTN  
MODEM or an ISDN terminal adapter.  
This command determines which of the external ports (MODEM, ISDN  
Port0, or ISDN Port1) will be used when a particular telephone number  
is selected.  
Format:  
TYPE0=ISDN0  
TYPE1=ISDN1  
TYPE2=ISDN2  
TYPE3=MODEM  
TYPE4=MODEM2  
Example: TYPE5=2  
Sets Telephone entry 5 to ISDN2

Calls  
DVST InstallationGuide  
TIMER=  
Call connection timeout period  
(default, 60 seconds)  
This is the period of time that the DVST will wait while trying to connect  
a call. This will vary depending on the type of call (ISDN or PSTN) and  
as there may be a delay in establishing International calls, the timer  
value should be increased.  
DIALCLR=  
...Sets time dial menu remains on screen  
(default, 30 seconds)  
10.4  
Callback  
This feature allows an operator to dial a remote unit and then have that unit  
automatically call the operator back. This can be a useful security feature. The operation  
of callback is as follows:  
Local unit calls remote unit.  
Call connects.  
Local unit passes the dial menu number (0 to 9) that the remote unit will call back.  
Call disconnects.  
The local unit waits for a return call.  
Remote unit waits for ten seconds then calls local unit.  
Local unit answers and contact proceeds as normal.  
CALLBACK=  
Set call back ON or OFF  
(Default, off)  
When the callback feature is switched on the option appears on the  
dialling menu to make either a normal call or a remote callback call.  
Normal call is the default and this is highlighted. By using the left and  
right arrow keys remote callback can be selected and deselected.  
Note:  
Callback must be enabled on BOTH the transmit and receiving units
