Sep 10, 1997 - 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 & 4-wire) interfaces, as required. For example, a user could have a 2-Wire RS-485 interface on one end and RS-232, RS-422 or 4-Wire RS-485 on the other end. Two-wire RS-485 versions can be changed to 4-wire RS-485 by simply changing a DIP switch.
