Industry Pack Modules IP501-x Serial 422/485 Communication These modules provide an asynchronous serial communication interface for your system. They have four asynchronous, full-duplex RS422B serial ports. Since the transceivers are compatible with the RS485 Large, 128-byte FIFO buffers reduce the processing burden on the CPU to increase the overall system performance. standard, you can also use a full-duplex RS485 interface for multiple driver support. However, for true half- Specifications Ordering Information duplex RS485 operation, use the IP502.
