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
must 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:
z
Local GET Status: gathers diagnostics from the unit connected to the network
z
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.
Table 4-1 Diagnostic 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
Normally 3.5 to 6.0W
Normally 4.0 to 5.5W
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 1/4 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:
z
the RSSI reading indicates local station signal strength in
dBm as heard by the remote
z
the Remote RSSI indicates how well the local unit receives
the remote signal measured in dBm
If “Radio Source” is in “Local” mode:
z
the RSSI reading indicates how well the local unit receives
the remote signal measured in dBm.
z
the Remote RSSI reading indicates local station signal
strength in dBm as heard by the remote
Normally +/- 3dB accuracy A
good received signal level
should be higher than -
90dBm
