Overview
CA-132/132I is a PC/104 module that supports the RS-422/485 serial interfaces, and can be used with PC/104 CPU modules or CPU cards that accept PC/104 expansion modules. CA-132/132I has two independent serial interfaces, which are accessed through RJ45 connectors. You can configure both ports for the RS-422 or RS-485 interfaces by DIP switch. The module’s industry-standard MOXA UART (16C550 compatible) is fully programmable. Moxa has implemented its patented ADDC™ technology for RS-485 automatic direction control, so there is no need to change jumpers to switch the module between driver and receiver. The built-in 16 KV ESD surge protection protects other devices connected to the RS-485 network.
