Connect Tech Xtreme/104-Express Opto - PCI/104-Express Four/Eight Port Opto Serial Interface Card

Adds 4 or 8 RS232, RS422 or RS485 Interfaces to PCI/104-Express Bus


Connect Tech's PCIe/104 serial cards offer advantages including rapid data transfer, high reliability and reduced system costs because of the stacking nature of the PC/104 form factor. Xtreme/104-Express Opto serial cards maximize ruggedness by adding 3 kV optical isolation to protect your industrial and embedded applications.

Xtreme/104-Express Opto includes a fractional baud rate generator that matches almost any baud rate accurately. Additionally, Xtreme/104-Express Opto offers large 256 byte FIFO buffers, 9-bit data support, and is suitable for industrial temperature requirements (-40ºC to 85ºC).

Connect Tech's PCIe/104 serial boards provide longevity for critical military, aerospace, medical, instrumentation and industrial control applications.

All Connect Tech PCIe/104 serial cards include lifetime warranty and free technical support.
