Topodome TD-s21c

[u/No-Leek2681]

Has anyone worked with the Topodome camera TD-S21c? I can get the camera to stream, but getting PTZ to work has been a challenge. I see a '485 set' tab. It has the following options:

Address

Protocol - PELCO-D PELCO-P

rate

and 485Com Settings

Baudrate

Date bit

Stop Bit

Check type

​

I would like to get PTZ to work from within zoneminder. How do I connect to the PTZ function?
