American Fibertek RT-746C-SL Four Channel Digital Video Rack Card Transmitter, Multi-Protocol RS485/RS422/RS323/Manchester, Contact Closure, Multimode

The American Fiberte RT-746C-SL is the rack card transmitter component of the 746C-SL series which transmits four channels of high-quality digitized video and one channel of multi-protocol data (RS485 (2 wire or 4 wire) or RS422 or RS232 or Manchester) and a contact closure on one singlemode optical fiber at 1310 and 1550nm. Designed to be completely transparent to all camera and monitor manufacturers, this system requires no field adjustments at installation or additional maintenance thereafter.

Diagnostic indicators provide a quick visual indication of system status. Rack cards can be mounted in the American Fibertek Card Cages: SR-20/2 or SR-20H/2 (redundant power supply).
