Description
The TC8116 is a time division multiplexer which can multiplex up to 16 channels of signals. It can be factory
or user configured to several different variations.
The typical unit has one main PC board (A board) with two interface SIMM modules. The main PC board
has eight RJ-11 ports: each RJ-11 port has one duplex data channel. The interface SIMM module is field
interchangeable. The extension PC board (B board) also has eight RJ-11 ports for additional channels 9
through 16 (for 8 channel units, these additional ports are not used).
The TC8116 multi-interface model offers several different interchangeable interfaces, such as RS-232,
RS-422, RS-485*, TTL, Dry Contact Relay, Analog or Intercom. It can be upgraded or reconfigured to
virtually any configuration; simply contact the factory should the need arise.
The TC8116 is based on modern FPGA (Field Programmable Gate Array) technology. As a result, it benefits
users by enabling optimum flexibility, low current consumption, high reliability and maximum MTBFs
(100,000 hours or better). Each unit has a built-in Signal Generator, Polarity Inverter switch, and Local &
Remote Loopback features to ease installation and facilitate troubleshooting procedures. Fiber optic
connectors are ST (optional FC); electrical connectors are RJ-11 Female. Power is 9 to 12VDC. Optional
power supplies are also available (see Chapter 5 - Specifications).
The TC8116 consists of two PC boards connected together internally by ribbon cables. Each PC board has
its own DIP switches, LEDs, optic connectors and electrical signal ports. The PC board with the "A" optic
connectors is referred to as the "A" board, while the board with the "B" optic connectors is referred to as
the "B" board. Each board's panel is designed with multiple status monitoring features. The fiber optic signal
is monitored continually so that, should an optic fault condition or cable breakage occur, the alarm will be
triggered and the corresponding LEDs will indicate the type & location of the problem.
*RS-485 will be available in a future release.
