8Pelco Manual C544M (2/98)3.1.1 Setting the Baud
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.
NOTE:
The operating baud must
match the baud rate set in the .SCP
Communications File for the
CM9760-CC1.

3.2 CONTROL CARD
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).

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.
