Broadcast & Receive Device (8-24 Port: RS232/RS-422)

Rollover or Touch for Expanded View. Scroll to Zoom.


The TC8916 Broadcast & Receive device is used in SCADA or poll-response networks with a Star topology to link up to 23 ports from a SCADA Host to RTUs.

Designed specifically for SCADA and process control applications with a Star topology, the TC8916 Broadcast & Receive Device broadcasts & receives information from remote devices. Transparent to all data sent in either direction, it is typically used to link SCADA Hosts to remote terminal units (RTUs) or programmable logic devices (PLCs) via fiber optic or metallic cable.

    Supports Polled/Response SCADA Networks
  • RS-232 or RS-422
  • Up to 24 Channels; Can be Cascaded
  • 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.
