DVST Installation Guide 3 3.1 Operation Operation 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.
Operation 3.3 DVST Installation Guide 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 succession without any operator control.
DVST Installation Guide Installation 4 Installation The DVST Transmitter is supplied as a wall mounted unit. 4.1 Rear Panel connections The DVST Transciever uses BNC connectors for all video inputs and outputs.

DVST Installation Guide 7 7.1 Modems Modems PSTN Connection (Modem) Connection to a PSTN telephone line is via a modem and modem port. 7.2 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.
Modems DVST Installation Guide 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.
DVST Installation Guide 7.3 Modems 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.
Modems DVST Installation Guide 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: M2INIT=AT&M1 &D2 \GO \EO E1 &C1 \JO SREG2=ATSO=1 ASYNC This sets the MINIT and SREG strings for correct asynchronous operation with the Trailblazer MODEM.
DVST Installation Guide DIAL= Modems 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.
Modems 7.5 DVST Installation Guide 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).
DVST Installation Guide 7.6 Modems Using a modem in ATMODE In this mode the Hayes set of commands is 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).
Modems DVST Installation Guide 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.
DVST Installation Guide 7.8 Modems 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.
Modems DVST Installation Guide No Dialtone In some cases the MODEM will not recognise the prescence of a dial tone from the exchange.
