CONNECTING THE PELCONET’S COM PORT TO THE GENEX MULTIPLEXER’S COM OUT PORT
Refer to Figure 48 and the instructions that follow.
Figure 48. Connecting PelcoNet to Genex Using the COM Port
1. Verify that the multiplexer has Version 4.1 or higher software for Genex units manufactured before November 22, 2002—or Version 1.12 or
higher for units manufactured on or after that date. (The version numbering was restarted in 2003, which is why newer units have a smaller
version number. The version number flashes on the monitor when power is applied to the multiplexer.)
2. Set the NET300 RS232/422/485 data port to Transparent, 9600 baud, 8 data bits, none (for parity), 1 stop bit, and off if it is not so set
already. (In the Interface Mode field on the configuration page for the interface settings, select RS-232.)
3. Create a cable using the diagram in Figure 48.
4. Attach the cable’s DB9 connector end to PelcoNet’s RS232/422/485 port. Connect the cable’s RJ-45 connector end to COM OUT on the back
of the multiplexer.
5. Connect the MAIN video output from the multiplexer to the NET300 transmitter.
6. Connect PelcoNet’s Ethernet port to the network using a Cat5 Ethernet patch cable.
