• To decode the radio traffic using configuration software, first start communications logging
by selecting option “c) Enable Comms Logging” from the debug menu. Next, in the diagnostics
screen select ‘Stop Terminal’ and then ‘Start Comms’. Configuration software now expects the
105G to be in monitor comms mode, and will decode all radio communications.
The display will show radio messages transmitted and received. Messages starting with RX are
received messages, CMD are transmitted messages and ACK are acknowledgment messages. At
the end of each received message is the RSSI (radio signal strength indication) in dBm.
If you select any message line with the mouse, information about the message will be displayed
at the bottom of the screen - the system address, RSSI and CRC (error-check) status. The “text
box” at the bottom middle of the screen decodes the message - that is, it decodes the message to
display I/O channel and value. Note – Configuration software can only decode the message
completely if the same configuration project corresponding to the system being monitored is
open.
You can display the register values in Decimal by selecting “Dec” at the bottom of the screen. If
you select “Dig”, the values will be displayed as a 0 or 1 digital value (1 if the 16-bit value is
greater than 50% - that is, the most significant bit is 1). If you select “Anlg”, the value will be
displayed as a 4-20mA range.
