PC/104 RS-232, RS-422, RS-485 (Software Selectable) Serial Interface Portholes Kit

Call for price


The 3541 provides four software-selectable RS-232, RS-422, or RS-485 ports. RS-232, RS-422, or RS-485 mode may be selected independently via software command for each of the four ports, eliminating the need for setting jumpers or DIP switches.

The board is designed using the XR16C864 UART, which provides a 128-byte FIFOs, 8 times larger than boards designed with 16C550 compatible parts. The larger buffers allow error-free operation even in high-speed applications. In RS-485 mode the C4-104.ULTRA offers automatic control of the RS-485 driver enable for trouble free network master arbitration. Additionally, the board allows RS-485 network termination, critical to robust multi-drop communication, to be selectively added to the circuit via a simple software command.

Includes 3541 PC/104 board, ribbon cable, and DB9 mounting plate for installation in an enclosure.

Note: This item has a minimum order quantity (MOQ) of 25 units. Please contact your sales representative with any questions.
