Model RSCOM2D: RS232 <=> RS422, RS232 <=> RS485 (using RTS) and, TTL/CMOS <=> RS232/RS422/RS485 converter with Screw terminals, DB9M connector, and edge mounted LED indicators.

• Very flexible interface converter for RS232, RS422 (4-wire, full-duplex), RS485 (2-wire, half-duplex), and TTL/CMOS applications.

• CFast Async interface converter for point-to-point (or multi-drop communications using RTS or TTL/CMOS control), at distances up to 4000 ft. and data rates up to 115.2Kbps.

GENERAL DESCRIPTION and TYPICAL APPLICATIONS:

The RSCOM2D is an Async bi-directional RS232 <=> RS485/RS422 interface converter for 4-wire RS485/RS422 applications (full-duplex point-to-point) or, by using the RTS (request to send) control line the unit can be configured as a 2-wire half-duplex converter (See RSCOM2A for automatic TX enable). The unit has fixed light bias on the RS485/RS422 receiver, jumper selectable termination, RS232 DTE/DCE selection, and operating mode settings. The unit has 3 edge mounted LED indicators, a screw terminal connector, and built-in transient protection. While the RSCOM2D is primarily used in 4-wire applications, the flexibility built into the unit allows for many other special applications as well. The unit will operate at speeds up to 115.2Kbps.

The RSCOM2D is designed for office and/or industrial applications (non-isolated), and is used primarily for 4-wire full-duplex, point-to-point applications (remote sign control, RS232 "extension core"); however, 33 on-board jumper settings provide a wide range of possible configurations to solve many communications problems.
