Pelco cs73m-d operation manual Connecting the MDA to AN External PC

Page 13

NOTE: The CM9760-MDA is configured at the factory for RS-422 communication. To communicate via RS-232, an internal DIP switch must be changed. Refer to the Communication Ports Setup section.

NOTE: The pin numbering of the wall block shown in Figure 5 applies to the Pelco RJ-45 wall block. A wall block purchased from a supplier other than Pelco may have a different pin numbering scheme.

CONNECTING THE MDA TO AN EXTERNAL PC

Perform this step if you are going to program your CM9760-MDA unit using a PC (personal computer).

Refer to Figure 5 and make a cable to connect the MDA to the PC. The figure shows a typical nine-pin sub ÒDÓ connector for the PCÕs COM 1/COM 2 serial port. Computers may differ regarding connector types and pin-outs. Therefore, always refer to the computerÕs manual to determine proper pin-outs.

If more than one MDA is to be programmed using a PC, note the following:

¥A maximum of 16 MDA units can be daisy-chained. To daisy-chain up to 16 MDA units, connect the RS-422 output of the first MDA unit to the RS-422 input of the second MDA unit and continue this method until the last MDA unit is connected (refer to Table D and to Figure 39).

¥If more than 16 MDAs are to be connected to a PC, a CM9760-CDU-T must be used. Refer to Figure 40 for an example of connecting over 16 MDAs to a PC. Note that a maximum of 64 MDA units can be connected to a PC for programming.
