The CP-132EL-I PCIex is designed for RS422/485 industrial communication. It supports 2 independent RS422 or RS485 ports. Each port can be configured separate. Available modes : RS422 fullduplex RS485 full duplex (4 wire) RS485 half duplex (2 wire). In RS485 modes applications enable transmission by simply sending data.
This is done by ADDC (Automatic Data Direction Control). The Transmitter is disabled with the end of the last character sent. No modification is necessary in programs. In addition built-in termination resistors guarantee data integrity. All of these features make CP-132EL-I PCIex suitable for harsh industrial applications.
