Hi,
I have an RS485 PTZ camera currently controlled directly via the serial RS485 by a PTZ keyboard/joystick. Given with the internet age now, ideally, I would like to have the manipulation go beyond the RS485 in the IP network. There are several questions with respect to the overall mechanism:
1. Do most of the manufacturers, e.g., Pelco PTZ camera, share some sort of the RS485 control protocol? How can I tell what control protocol a vendor or manufacturer uses? Or simply put, whether they even bother to have a common/standard protocol instead of a proprietary ones?
2. Why is MODBUS standard not found in the IETF/RFC?
3. Is MODBUS a true standard that address the industry wide IP-RS485 protocol? Ironically, a standard of RS485 protocol does not seem to exist based on the reading of www.rs485.com.
Appreciate any comment/suggestion.
