Isolated RS-232 to RS-422/485 Converter Card

● 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


The PCISA-7520A series is exactly the same as I-7520A series except for the PCI and ISA Interface and is designed for easy installation. The PCISA-7520A 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.
