Please remember to terminate the last
dome of each output.
4 wire RS422 notes
1. Ensure that the dome/receiver is set for 4 wire
telemetry, full-duplex.
2. The controller must be set for 4 wire using either a
rear panel switch or menu access. Full-duplex must
be selected from within the setup menu.
3. Baud rates for the controller and dome/receivers
must be the same. It is advisable to use 9600 baud
to reduce the possibility of corrupted data causing
intermittent control.
Panasonic specific notes
• FS616 - A single RS485 output is available. Connect
the RS485 output to the Starcard as shown.
• SX350 - Not compatible with 4 wire telemetry.
• SX550/850 - Not required as each matrix RS485
output card has eight individual outputs.
