Communication log

This page uses vendor protocol, not Modbus
Frame layout 01 · 51 · folder · 00 · volume · XOR · 02 integrity is a single XOR byte, not CRC16

Here folder and volume go in one frame. Shorter than Modbus, but there is no read command so the "Read current values" button is not shown on this page

The box replies with byte 1 as 52 while the command we send is 51 They differ by one bit. If 51 comes back it means a cable echo, not the box replying — the tool warns you

This family ships from the factory speaking this protocol by default. Use this page for units not ordered with Modbus or when the Modbus page gets no reply
Other: Modbus RTU · Choose how to command it
