Description
Intended for Bus or String topologies, the
TC2900 Multi-Drop Fiber Optic Multiplexer links up to 12 monitoring devices (RTU's
or PLC's) fitted with RS-232, RS-422, or RS-485 (2 or 4 wire) interfaces to a
Host controller or CPU. It supports asynchronous data rates up to 38.4 Kbps.
The TC2900 works in a "polled-response" (also
called Slave/Master) types of communication network. Model TC2900 is the
Master, TC2901 is the Slave Units. A wide-range temperature version (-20°C to
70°C), Model TC2900T, is available for extreme environment applications.
Each TC2900 unit provides two pairs of fiber
interfaces and 4, 8 or 12 independent RS-232 and/or RS-422/485 channels. The
RS-232 channels can be used for data or as telephone extension with the Model
TC1900 "Quick-Talk" Telephone
Extenders. Diagnostic LED's include Tx and Rx for each channel, Power A,
Power B, VccA, VccB, SyncA, SyncB, LP-A and LP-B. An Anti-Streaming capability
is provided to prevent a single node failure (e.g. "babbling") from bringing
down the entire network.
