The TC1540 is a highly versatile, switch-selectable 2/4-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 link a RS-485 interface on one end with an RS-232, RS-422 or 4-wire RS-485 interface on the other. The 2-wire RS-485 versions can be converted to 4-wire RS-485 by changing a DIP switch.
