NETWORK TROUBLESHOOTING

Part No. 001-4090-101/102
4.2.2 OFFLINE DIAGNOSTICS
Offline diagnostics are used for trouble-shooting and test transmissions to remote units or to a local
connected unit. Offline diagnostics are intrusive as they take control of radio channels. User applications may have
to be offline.
4.3 GET STATUS
The Get Status function allows the user suspecting network communications problems to gather
diagnostics and check tolerances as follows:
l
Local GET Status: gathers diagnostics from the unit connected to the network
l
Remote GET Status: gathers diagnostics from a suspect remote unit connected to the network
Values displayed are taken at the moment the GET Status button is pressed. The GET Status does not
continuously update. Press the Clear button and press GET Status again to update the information.

Field Name
Description
Tolerance
Unit ID
Identifies the unit whose diagnostics are displayed
Between 1 & 254
FPWR
Approximate measure of transmit RF power
If power read from Bar graph or from reported diagnostics
Note: If power read from an external wattmeter
RPWR
Approximate measure of reflected power.
Online Diagnostics:
Offline Diagnostics:
0 if reflected power is within
limits, 1 if reflected power is too
high. The threshold is set to
approximately 1/3 of FPWR
Value is in watts, ideally
close to zero, but values up to
about 15% of FPWR may be
encountered in properly
operating systems.
If a dummy load is used to test a
unit, expect reflected power to
be less than 0.2W
RSSI
and
Remote RSSI
If “Radio Source” is in “Remote” mode:
l
the RSSI reading indicates local station signal strength in dBm as
heard by the remote
l
the Remote RSSI indicates how well the local unit receives the re-
mote signal measured in dBm
If “Radio Source” is in “Local” mode:
l
the RSSI reading indicates how well the local unit receives the re-
mote signal measured in dBm.
l
the Remote RSSI reading indicates local station signal strength in
dBm as heard by the remote
No/- 3dB accuracy A
good received signal level
should be higher than -90dBm
