The PCISA-7520 series card provides RS-232 to RS-485 (or RS-422) converter function that is exactly the same as I-7520 series. It is designed for easy installation, powered from the PCI or ISA Interface but without PCI and ISA functions. The PCISA-7520 series is equipped with both an RS-232 serial port and an RS-485 serial port. The RS-232 port is designed to communicate with the local Host PC, the RS-485 is designed to communicate with the remote IO module.

For adding more serial ports to a PC, please refer to VXC/VEX series cards. back •No External Power Supply required •No Driver installation required •3000 VDC Isolation Protection •Auto Switching Baud Rate, 300 ~ 115200 bps •ESD Protection for the RS-232/422/485 Data Line •Transmission Speed of up to 115200 bps •Can be used in an ISA Bus, a PCI Bus or any system with an RS-232 Interface back Power PCISA-7520R PCISA-7520AR Serial Interface RS-232 TxD, RxD, GND RS-422 - TxD+, TxD-, RxD+, RxDThe RS-422 and RS-485 cannot be used simultaneously RS-485 Data+, Data- 2-wire Cabling/4-wire Cabling Belden 8941 (2P twisted-pair cable)/Belden 8942 (4P twisted-pair cable), when different cables are used, the transmission distance may change Transfer Distance Max. 1,200 m at 9.6 kbps; Max. 400 m at 115.2 kbps Max.
