Serial Port

5.2.1

Description

This is a standard RS232 port to handle the serial messages. It has a fixed port settings of
19200, 8, N, 1. The PDU uses this port. The protocol for request and response of data is a
fixed 8-byte packet. It will always start with SOH and end with a simple checksum (~sum +
1). The packets will include all the functionality found in the DeviceNet Extension object.
The data is in ‘big endian’ format here (big end first: MSB-LSB). The packet is outlined below:
