4.4. Display Serial Logs
The Serial Interface Logs page provides a log of received and transmitted serial port messages. Up to 128
bytes per message and up to 128 messages are logged. It is intended to help with debugging serial
connectivity problems, determining the proper start and end of transmission bytes, and diagnosing device
problems.
The format is as follows:
Pkt(n): ddd:hh:mm:ss.mmm Rx/Tx:<data>
Where:
ddd – days since last system restart
hh – hours since last system restart
mm – minutes since last system restart
ss – seconds since last system restart
mmm – milliseconds since last system restart
<data> - Data packet received.
• For Modbus slave data, all data bytes shown in hex (xxh) format.
• For Raw/ASCII and Modbus/ASCII data
- ASCII characters displayed as characters
- Non-ASCII displayed in hex (xxh) format
