The 3603 PCMCIA serial interface card provides one RS-232 serial port capable of data rates to 115.2K bps. The board implements all modem control signals for maximum compatibility with a wide range of peripherals. The 3603 utilizes a 16C550 UART that provides 16-byte Tx/Rx FIFOs and ships with a 12 inch detachable cable that terminates to a DB25M connector.

If you need a DB9M cable, order the 3603-DB9. For custom baud rates and 9-bit protocols, order the 3603-SN which utilizes a 16C950 UART.

Note: This item has a minimum order quantity (MOQ) of 25 units.
