5-4-10. Communication with control device (RS-485)
The camera can be controlled from a control terminal (PC, for example) or the
remote control unit provided by Ikegami, over RS-485 Link.
The RS-485 is the recommended standard by EIA for a serial data communication,
one class higher than RS-422 which is for Multi-drop connection, but the 485 is the
Multi-points connection type. Maxim communication speed is 10Mbps and normally
extendable up to 1,200 meters.(3,600 ft).
When you make RS-485 connection, make it sure to connect the right terminal as
there are plus and minus polarity, and also make sure to terminate at the last
machine in the link of daisy chain.
For details, refer to the Communications Specifications.
