Pelco System 9760 manual Connecting AN ACD DB9 Port to a CM9700-CC1 RJ-45 Port, PV140

CONNECTING AN ACD DB9 PORT TO A CM9700-CC1 RJ-45 PORT

To connect an ACD DB9 port to a CM9700-CC1 RJ-45 port, refer to Figure 61 and do the following:

1.Connect the 9-pin side of the PV140 converter to a DB9 port of the ACD.

2.If necessary, connect the +12 VDC power supply to the PV140 converter; otherwise, proceed to step 3. (The power supply allows the PV140 converter to communicate serial port data over wire pairs for distances up to 4,000 feet [1,219 m] on the RS-422 side.)

a.Connect the black and white striped wire from the power supply to the +12 VDC terminal on the converter.

b.Connect the solid black wire from the power supply to the GND terminal on the converter.

3.Connect RD(B) on the converter to terminal 8 (RX+) on the wall block.

4.Connect RD(A) on the converter to terminal 7 (RX-) on the wall block.

5.Connect TD(B) on the converter to terminal 1 (TX+) on the wall block.

6.Connect TD(A) on the converter to terminal 2 (TX-) on the wall block.

7.Connect the wall block to an RJ-45 port of the CM9700-CC1 using an RJ-45 reversed cable.
