| Our PCISA-7520/AR/R are RS-232 to RS-422/RS-485 Converter Card Communication Boards with a D-sub 9-pin cable. The PCISA-7520/AR/R boards are bus-powered versions of our I-7520AR module, providing the convenience and space savings from internal mounting of the converter. An external power supply is NOT required. This card does not add additional com ports to the PC. Instead, it requires connection to an existing RS-232 com port; optional cable is part number CA-0915. |
