2.0 DESCRIPTION
The Pelco 9760-IRC VCR Controller provides remote control of most VCRs
equipped with an infrared receiver for controlling standard functions: play, record,
stop, fast-forward, rewind, and pause. Eject control depends on the VCR model.
This reduces the need for modifications to VCRs.

2.1 GENERAL FEATURES
The Pelco 9760-IRC is housed in a rack frame and connects to one Sercom port on
the rear of the CM9760-CC1.
•A fully populated Pelco 9760-IRC unit consists of the following:
a.One communication card (interfaces with CM9760-CC1)
b.Four VCR control cards
•Each control card controls:
a.Up to 32 VCRs
b.Up to four different VCR brands and/or models
•Up to 128 VCRs can be controlled by one unit.
•Up to 16 IRC units can be linked in sequence (that is, daisy-chained) giving
control of up to 2,048 VCRs (refer to Figure 2)
The control cards accept messages from the CM9760-CC1 in the same manner as
a normal GPI (General Purpose Interface) relay card.
VCR control signals are transmitted by infrared control cable (IR control cable)
attached to the VCR.

To install the Pelco Infrared VCR Controller, proceed as follows:
1.Set the baud.
2.Set the start address.
3.Connect the CM9760-IRC to the CM9760-CC1 host.
4.Connect additional IRC units in daisy-chain fashion.
5.Connect VCRs to the Video Matrix Bay (CM9760-MXB).
6.Connect the IR control cables to the VCRs.
Each step listed above is detailed below:
3.1 COMMUNICATION CARD
The communication card (refer to Figure 4) has a bank of eight DIP switches used to
do the following:
1.Set the operating baud of the unit
2.Set the start address
In Figure 5, DIP switch number 2 is ON.

3.1.1 Setting the Baud
NOTE:
The operating baud must
match the baud rate set in the .SCP
Communications File for the
CM9760-CC1.
3.2 CONTROL CARD
NOTE:
The VCRs connected to a
single microprocessor must be in the
same brand and model. Brands and
models required should be specified
at the time of order.
Bauds of 2400, 4800, 9600, and 19200 are available. The communication protocol
uses eight data bits, one stop bit, and even parity.
The baud is set using DIP switches 1 and 2 according to Table A.

The CM9760-IRC can have up to four control cards installed.
Each control card has four microprocessors.
Each microprocessor controls two DB9 output connections.
Each DB9 output controls up to four VCRs (refer to Figure 6).
This enables one Pelco CM9760-IRC to have infrared control of 128 VCRs (that is,
four control cards multiplied by four microprocessors per card multiplied by two
DB9 outputs per microprocessor multiplied by four VCRs per DB9 output equals
128 VCRs).

3.2.1 Setting the Start Address
Each Pelco CM9760-IRC unit requires a six-bit start address. The start address is
configured using the DIP switches on the communication card (see Figure 5: DIP
switches). Each control card occupies one address space. An IRC unit occupies
four address spaces (if there are only two control cards in the unit, it still occupies
four address spaces).
The start address of an IRC unit is set with the DIP switches on the communication
card per Table B.
Unlike an IRC unit, a serial GPI occupies one address space. In the sample system
outlined in Figure 3, the start addresses would set up according to Table C.
The start address of each control
card in the unit is set by internal default.

3.3 CONNECTING THE CM9760-IRC TO
THE CM9760-CC1 HOST
Each CM9760-IRC has two RS-422 ports; one labeled IN (male) and the other
OUT (female).
To connect a CM9760-IRC to the CM9760-CC1 host, connect a SerCom port on
the host to the IN RS-422 port on the IRC. The data pin connections are shown
below in Figure 7.

3.3.1 Connecting the CM9760-IRC to a CM9760-CC1 Host
via Serial GPI
A CM9760-IRC can be daisy-chained from a serial GPI already connected to a
SerCom port of a CM9760-CC1 (CPU). The wiring is the same as for Section 3.3.
Connect the RS-422 OUT port of the serial GPI to the RS-422 IN port of the IRC
(refer to Figure 8).
3.4 CONNECTING ADDITIONAL IRCs IN SEQUENCE
NOTE:
Sixteen is the maximum
number of racks that can be daisychained from one port of the host
CPU.
3.5 CONNECTING VCRs TO THE VIDEO MATRIX BAY
(CM9760-MXB)
VCRs must be connected to the CM9760-MXB (Video Matrix Bay). Two standard
coaxial cables are needed:
(1) One to run from the VIDEO OUT port on the back of the VCR to the desired IN
port on the VMB.
(2) The other to run from the VIDEO IN port on the VCR to the desired OUT port
on the Video Matrix Bay.

3.6 VCR CONTROL SIGNAL OUTPUTS
An IRC has up to 32 D9 female output connections numbered J1 to J32, each able
to control four VCRs (refer to Figure 6). Every DB9 output supports four IR control
cables. Each IR control cable controls the functions of a single VCR.
The wiring for each DB9 output is shown below in Table D.

3.6.1 Transmitting VCR Commands
NOTE:
Once installation has been
completed, the appropriate programming must be made in the 9760 Configuration files (ie: SCP/.GPI/.CAM).
Connect an IR control cable to one of the DB9 infrared output connections on the
IRC. Run the cable to the target VCR.
For best results in transmitting the VCR commands (play, record, stop, fast forward, rewind, pause), the IR LED at the end of the IR control cable must be placed
directly over the receiving port on the front of the VCR.
