The INT-422-P2P-D interface allows a double peer-to-peer RS422 connection, making it possible to build a closed loop, “daisy-chained” communication network between GFE's CHAMELEON Panels (G-ONE, GEKKO, OCTO+, NODE+ and CHAMELEON REPEATER). The INT-422-P2P-S interface allows one single RS422 connection. Mainly used for integration to 3rd party BMS systems or for a single extension connection to a CHAMELEON Display. For more detailed information, such as commissioning, network topology options and installation troubleshooting, please refer to the CHAMELEON Network manual or contact our Technical Support team.
