Baud Rate Settings; Rs-485 Bus Matching Resistance - Comelit MPTZ37IR Manual Del Usuario

(sw1 = 1 + sw3 = 4).
For complete, detailed settings please refer to the "Address Code Mapping Tables".

2.1.3 Baud Rate Settings

The 4th and 5th "Function" (FUN) DIP Switches set the Baud rate. Factory-default setting is 2400
bps.
Baud rates: 1200 bps, 2400 bps, 4800 bps, 9600 bps selectable.

2.1.4 RS-485 Bus Matching Resistance

th
The 8 DIP switch of FUN SW2 is to select the matching resistor. In order to prevent interference
of the RS-485 communication signal and other signals, the parallel matching resistor is needed
in the communication interface of the dome camera at the far end of the RS485 bus run.
th
Use the 8 switch of the FUN switch group to connect the resistor the the RS485 bus ONLY IF
THE CAMERA IS THE LAST CAMERA ON THE BUS. If there are multiple PTZ cameras on
the RS485 bus, all others should not have a termination resistor applied.
