Hi - I would like to have my PELCO-D camera and VISCA (UART) camera on the same serial RS485 bus, let's call it COM1. Does PTZ-Controls separately try to open COM1 for PELCO-D and VISCA, or will it open COM1 once and send either instruction depending on which camera? The reason I ask is if I change the baud rate on the settings on the PELCO COM1 it doesn't show the same on the VISCA COM1.
