  • Anti-Streaming Capability on Each Channel
  • Hardened Temperature version exceeds NEMA & CALTRANS specs
  • LED Indicators for Each Channel’s Tx & Rx Status
  • Stand Alone or Rackmount


The TC8916 is often used in SCADA applications with a Star topology to link a SCADA Host to RTUs. The TC8916’s RS-232/RS- 422 user ports can be extended with the use of a fiber modem or multiplexer. When the Host Polling Device sends information to the TC8916 via the RS-232/RS-422 Host Port, it will broadcast to each of the RS-232/RS-422 user ports. The addressed remote device(s) will then respond back to the Host Device.
