Model TC8610 4 Channel Serial-to-T1 orE1 The TC8610 is a 4 Channel Serial-over-T1/E1 multiplexer with built-in power redundancy. It supports data rates up to 38.4 Kbps. Features    Product or Application Questions (click here) 4ch RS-232 or 4ch RS-422/RS-485 Two or Four Wire RS-485 Very Low Latency - 85µs Individually Isolated Ground for each Serial Port Supports 120Ω & 75Ω E1 Built-in Power Redundancy Rack Mount or Stand Alone Description The TC8610 is available in four configurations: 4-Channel Async RS-232 with Control 4-Channel Sync RS-232 4-Channel Async RS-422 / RS-485 Contact factory for other combinations Interfaces include RS-232, RS-422, and RS-485. Synchronous versions must be RS-232. Diagnostics are extensive and 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. The built-in sync mechanism verifies both device and T1/E1 link operation. No other test equipment is required for link and device verification. The TC8610 is compatible with standard 100Ω T1 for copper line lengths up to 6000ft and up to 2.5km for 75Ω / 120Ω E1 (copper line length is the distance between the TC8610 and the T1/E1 cross-connect). T1/E1 uses RJ45 connector and the serial channels use RJ-11. Optional BNC adapter cable is available for 75 Ohm E1. Power is 12VDC standard or optional 24VDC, -48VDC, 125VDC, or 115/230VAC with an external power cube. Optionally, a high temperature version (-20°C to 70°C) and extreme temperature version (-40°C to 80°C) are also available.   TC8610 Specifications Electrical RS-232, RS-422 or RS-485   Connector RJ11 Data Rate up to 38.4Kbps T1 or E1 Connector RJ45F Data Rate 1.544 Mbps or 2.048 Mbps Alarm Dry Contact Normal Open Visual Indicators System Status PWR A, PWR B, VccA, VccB, Alarm, Link, Sync, Activity Electrical Signal Status TX, RX, Power Standard 12VDC @ 300mA Optional 24VDC, -48VDC, 125VDC, or 115/230VAC (with external power cube) Temperature Operating -100C to 500C Hi-Temp (optional) -20° to 70°C Storage -400C to 900C Humidity 95% non-condensing Physical (Standalone/Wall Mount Unit) Height    (3.53 cm) 1.4" Width (18.14 cm) 7.1" Depth (24.89cm) 9.8" Weight (907 gm) 2 lbs  Typical Application (Application Questions) The TC8610 offers an inexpensive, plug and play method for connecting up to four serial devices over existing T1/E1 links. Popular applications include: Transporting asynchronous RS232/RS422 Transporting SCADA communications Protocol-transparent Supports SEL Mirrored Bits®** Connecting two Power Utility teleprotection relays The TC8610 can also convert the RS-232 Async to RS-422/RS-485 signals running from the local side to the remote side or vice-versa. **NOTE - Mirrored Bits® is a registered trademark of Schweitzer Engineering Laboratories Inc.
