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.

NOTE: The numbering of the screw terminals on the wall block shown in Figure 61 applies to the Pelco RJ-45 wall block. A wall block purchased
from a supplier other than Pelco may have a different numbering scheme.
