March 18, 2014 - TC Communications announces TC8610 Serial-over-T1/E1 Multiplexer, suitable for SCADA and protective relay communications in Power Utilities, TC8610 Serial-over-T1/E1 Multiplexer is a low latency, low cost method for connecting up to four serial devices over existing T1/E1 links. The TC8610 features a latency of less than 85μs and supports all popular serial connectivity applications including:
- Transporting asynchronous RS232/RS422
- Transporting SCADA communications
- Connecting two Power Utility teleprotection relays
The TC8610 supports RS232, RS422 and RS485 (2- or 4-wire) interfaces up to data rates of 38.4 Kbps. RS232 interfaces support both synchronous mode or asynchronous with control signals (CTS/RTS). The TC8610 is compatible with standard 100Ω T1 for copper line lengths up to 6000ft and up to 2.5km for 75Ω / 120Ω E1.
Each serial port features individually isolated ground to eliminate problems with varying ground potential. Diagnostics are extensive and include a built-in sync mechanism that verifies both device and T1/E1 link operation. No other test equipment is required for link and device verification. Additional diagnostics include DIP switches for Local & Remote Loopback and other application configuration switches. Each unit also provides multiple LEDs for Alarm, Power, Vcc, T1/E1 Status, and Tx & Rx LEDs for each channel.
Power redundancy is standard and optional high temperature versions (-20°C to 70°C) and extreme temperature versions (-40°C to 80°C) are also available.
