MLRV-A Automated Video Receiver Module
DLGB Downlook Grabber Board
Two cables are connected from the
Downlook Interface card to the DML5A
backplane.
A 25-pin cable for the pictures and a
9-pin cable for the serial communication.
Both cables can have a maximum length
of 30 meters (100 feet).
These cables are not supplied with the
Downlook Interface.
The Automated MLRV-A Video Receiver Module provides
for the receiving of video images over the regular telephone
lines following the Event information.
One MLRV-A module connects to and works with one Digital
Receiver line (DRL2A). The MLRV-A can only connect to
and work with the Sur-Gard MLR2 Multi Line Receiver.
The MLR2 Receiver is a two line receiver expandable to 14
lines, each receiver line, if required can have the MLRV-A
module, if expanded to a maximum number additional power
must be taken into consideration.
The MLRV-A can be housed in one of two expansion cages
available, the MLRXV or MLR2XV, both are 19” rack mount
and should be located in the same cabinet as the MLR2
receiver. A four wire connection must be made between
the MLRXV or MLR2XV backplane board and the back plane
board of the DRL2A.
The Automated MLRV-A provides for two outputs, a Coaxial
video output off a BNC post and PC output by a 25 pin
video bus and 9 pin data bus. The MLRV-A can be set for
video out, PC out or both.
Video images transmitted to the video monitor and PC also
include the Account code, time and date and the camera
number with amount of images to be sent.
Two set’s of dip switches in the MLRV-A provide for several
options when viewing the video on a Video monitor, they
allow for large or small account code, flashing information
and how long it will stay on the screen. The options are
only applicable to the video monitor, on the PC the Downlook
software will display all images with extended account
information.
To input the Downlook Video into a PC it will be necessary
to have a DLGB card, one DLGB works with one MLRV-A
receiver module.
A standard 486 or Pentium PC will be required, up to 4
DLGB cards can be placed into one PC.
Each DLGB occupies an ISA slot.
