Connect Tech Xtreme/104-Plus 16 Port - PC/104-Plus Sixteen Port Serial Interface Card

Adds Sixteen RS232, RS422 or RS485 Interfaces to PC/104-Plus Bus


Connect Tech’s Xtreme/104-Plus 16 Port offers 16 ports of switchable RS-232/422/485 on a single PC/104-Plus card. This provides the highest port density and most flexible PC/104-Plus serial port solution available.

Dependability, high speed data transfer rates, and high density makes the Xtreme/104-Plus 16 Port a must where space is at a premium.

The Xtreme/104-Plus 16 Port is ideally suited for embedded systems where high serial port count and a small footprint is required. Example markets are remote submersibles, remote aerial or land vehicles, remote monitoring stations, or anywhere that high serial port density is required.

Features and Benefits

  • Flexibility: 16 RS-232/422/485 serial ports
  • Speed: Data rates up to 1.0Mbps RS-232 and 4.16Mbps RS-422/485
