Ver.1.00 PCI –compliant I/O RS-422A/485 4ch Serial I/O board This PCI board was designed for extending RS-422A/485 COM-4DL-PCI compatible serial communication functionality on your PC. COM-4DL-PCI has four RS-422A/485 communication ports. With a 64 byte built-in FIFO buffer for transmission and reception of each channel, the product supports a baud rate of up to 230,400bps. It also comes with a Windows driver, which allows boards to be used as OS-standard COM ports.

Ver.1.00 Types of Cables and Connection Examples The figures below show examples of how to connect the cable for the board. The RS-422A/485 interface works based on a differential signal whereby the signal is carried by the potential difference between two lines (+ and -). Using twisted pair cable is recommended to improve resistance to noise.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
