Wireless Transceiver Tool (TLX) (For WFLN Version 1)
Diagnostic Commands
You can use the TLX to get diagnostic information such as channel energy values and the number of
incomplete messages. This diagnostic information can help you troubleshoot during and after startup if
communication problems occur. The following sections provide detailed information about the ENERGY,
DIAG, CLEAR, and REBOOT commands.
Viewing Channel Energy Values (ENERGY)
You can use the ENERGY command to view the current RF energy values of each of the 16 available
wireless FLN channels. This is useful information during WFLN startup for deciding which channel to use
or troubleshooting communication problems. Prior to powering up the FLNXs and FPXs, the RF energy
value should be
less than 60
(hexadecimal) on the Channel selected for the WFLN.
Energy values of approximately 40 indicate no RF energy was detected on the channel. Energy values
of approximately 60 to 80 indicate active RF energy, such as from the WLAN or an 802.11 wireless
Ethernet network.
To view the RF energy values of the channels:
1. Type
ENERGY TLX
, and then press
ENTER
.
2. After the energy scan is complete, run the SCAN command to rebuild the TLX binding table.
This command will take about five minutes to complete. While the TLX is scanning the
channels, the LED will be yellow and blinking.
With the WFLN powered up, the RF energy value should be between 60 and 80 (between 6
x
and 8
x
,
where
x
= 0–9 or A–F).
