DVSTInstallationGuideIntroduction
1Introduction
DVSTis thegeneric namefor a rangeof productsdesigned to storeand transmitdigital
pictures at a higher quality and speed than previously possible.
1.1DFT-0150 Transmitter
The DFT-0150 (Digital Fast Transmission) transmitter will process the imagesfrom up
to sixteen cameras for transmission or reception over ISDN or PSTN telephone lines.
1.2Telemetry
The DFT 0150 can control telemetry cameras at the local site using built in telemetry
equipment.
1.3Event monitoring (Alarms)
Theinternalalarmverification system forDFT0150transmitterallowstheunittomonitor
and act onexternal events.This canfreeze a picturefrom thecamera thatcorresponds
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.
1.4Audio option
Audio transmission is available allowing two way, half duplex, (one way at a time)
communication. (Transmission medium must be 19200baud or faster)

3Operation
3.1Callback
The callback feature allows an operator at a monitoring station to call a DFT0100
transmitter onsite and configure the unit to automaticallycall 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.
3.2Alarms Feature
Thealarmsystemforthe DFT0150 transmitterallowstheunittofreezethepicturesfrom
camerasthatcorrespond with thealarminputsthathave been triggered.Thesepictures
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.
Ifthe fallback numbersarebusy thetransmitter will automaticallykeep callingbetween
telephone entries 0 and 1 until onebecomes free. However theuser can configure the
DFT0150 to automatically call upto four numbers unitl one becomes free.
Dependingonhowthe transmitter hasbeenconfigured,incomingalarmsarehandledin
different ways.

7.1PSTN Connection (Modem)
Connection to a PSTN telephone line is via a modem and modem port.
7.2MODEM Commands
MODEM=
The MODEM= command controls three distinct parameters.
Tech note:Thereasonisas follows;ifsetto ATMODEtheDVST attempts tocommunicatewith the
MODEM when starting up, exiting set up mode etc. The DVST will wait a set period of
timefor repliesbefore givingup. This willconsiderably slowthe system ifno MODEMis
attached.
Sets MODEM operation, three parameters:
OFF
(default, OFF)
DIRECT, ATMODE
(default, ATMODE)
The DIRECTmode is used if the MODEM has its telephone numbers
stored internally and the DVST does notpass 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.

This is called transparent MODEM mode and is terminated by
pressing the ESCAPE or ESC key.
MBAUD=
MODEM2
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
Inthe asynchronous modetheMODEMcontrols theflowofdata using
RTS/CTS signals.
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=

DIAL=
Modem dial string
(default, ATDT)
This isthe commandthat mustprecede allnumbers that the MODEM
has to dial. Typically the MODEM will dial using either pulse or tone
dialling. This is dependenton thetelephone exchangethe MODEMis
connectedto,mostmodern exchangesareabletoaccepttonedialling
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 bedialled to access outside lines can have thisadded to thedial string,
typically ATDT9.
7.4Modem 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, forexample those usingPEP (Packet EnsembleProtocol), can onlybe used
in the asynchronous mode.

7.5Connecting a modem in direct mode
This mode uses a modem in a ‘dumb’ mode, and purely relies on thehardware control
lines.Telephonenumber selection, andallotherconfigurationmust be performedatthe
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
connecthas beencompletedthe modemraisesit’s DCD line,confirmingit isconnected
with the remote location.
A call already being active is indicated by the DCD line being active (high) from the
MODEM.
Call answer request
Ifa callisincoming, the modemanswersthe call,establishesthe physicallink,and then
raisesDCDtoinformtheDVSTunitthat a call ispresent.TheDVSTunitrespondstothis
by taking DTR active (high).
Call disconnect.
This isrequested bydropping the DTR signal. Asuccessful disconnectis confirmed by
the DCD line being dropped by the MODEM. In this mode the DTR line remains low.
Configuration of modem in direct mode
Noconfigurationcan beperformedbythesystem, howeverthefollowingarerequired of

7.6Using a modem in ATMODE
InthismodetheHayessetofcommandsisused,allofwhichbeginwiththelettersAT.
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.
Todial acallthesystem sendsthedial string (setbyDIAL= intheDVSTsetup menu)to
the modem, followed by the number selected.
For synchronous operation the modem switches tosynchronous mode on connection.
Whenthecallconnecthasbeencompleted the modemraisesit’sDCDline,confirmingit
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 acall is incoming,and the DTRline is high,the modem answersthe 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

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 totransmit or send these values to the MODEM using theSEND 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 MODEMPossible 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.
The call must disconnect on a high to low transition of
DTR (Data Terminal Ready).
Only answer a call if DTR is present.
Auto-answer may be set if required.S0=1
Check MODEM manual

The modem should ignore RTS.&R1
Asynchronous Modems:
Extra action required of Asynchronous MODEMPossible AT settings
Asynchronous mode must be enabled.&M0
Flow control must be enabled on RTS/CTS.&K3
Error correction enabled ( if needed ).Refer to MODEM manual
in such a mode that this configuration is recalled automatically on power up. This will
help to ensure correct operation aftera power failure. Consult you modem instructions
for details of how to achieve this.

7.8MOTOROLA 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).
Enterthesetupmodeandconfigurethe DVST for operationwiththeVFASTMODEMby
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 answeron number ofrings command *AA1is not validin 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 LtdPage 25
ModemsDVSTInstallationGuide
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&W1Where
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

DVSTInstallationGuideLeasedLineTransmission
9Leased Line Transmission
Leased line transmissionis generallyused whena dedicatedor privateline isavailable
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 conventionalModems can operate on leased lines althoughthe 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.
9.1Leased line terminology
In leased line terms the receiver or calling unit is set as ORIGINATE.
The transmit unit is set to ANSWER.
9.2DVST set up for leased line operation
Whenleasedlineoperationis selected, thetypeof transmission selected(via the X21or
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)
Dedicated Micros LtdPage 39
LeasedLineTransmissionDVSTInstallationGuide
ORIGINATE

9.4ASCOM 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.
