The TC1540 is a highly versatile
2-wire RS-485 fiber optic modem that can mix or match RS-232, RS-422 or
RS-485 (2-wire or 4-wire) interfaces, as required. For example, a user
could have a 2-wire RS-485 interface on one end and an RS-232, RS-422 or
4-wire RS-485 interface on the other. 2-wire RS-485 versions can be
converted to 4-wire RS-485 by simply changing a DIP switch.
The TC1540 supports asynchronous
data rates up to 500 Kbps*, depending on the electrical interface, and is
compatible with all popular types and sizes of multimode (850/1300nm) or
single mode (1300/1550nm) fiber optic cable. Distances up to 80km are
possible.
Diagnostics include a built-in
Test Signal Generator that verifies both device and fiber optic link
operation. This feature benefits users by helping technicians verify that
both local and remote devices and the fiber optic link are operating
normally. Local and Remote Loopback Tests are available to verify electrical
and fiber connections.
Eight DIP switches and seven LED
indicators are provided to help installation and troubleshooting. An
extreme temperature version (-20°C to 70°C), Model TC1540T, is also
available.
Fiber optic connectors are ST or
FC. Electrical connectors are terminal blocks. Power is 12VDC at 250mA;
optional 24VDC or 115/230VAC with an external power cube.
