VL (Firmware Version - verbose) Command

WA (Active Warning Numbers) Command
WN (Active Warning Numbers) Command
Warning Number
Description
Under-voltage. This is caused if the supply voltage falls below the minimum threshold for the lowest power level (2.8 V). If/when the voltage
1
rises above the threshold, the warning is deactivated. The module will not transmit below this voltage threshold.
2
Over-voltage. This is caused if the supply voltage exceeds 5.75 V. Transmission is not allowed while this warning is active.
Under-temperature. This is caused if the temperature sensed by the module is less than -40 C. The module does not artificially limit operation
3
while this warning is active, but module functionality is not guaranteed.
Over-temperature. This is caused if the temperature sensed by the module is greater than 105 C. The module does not allow transmission nor
4
reception while this warning is active. The warning is deactivated when the temperature falls to 100 C.
Power reduced. This is caused if the transmit power has to be reduced from the level programmed by PL Command due to insufficient supply
5
voltage. The 1 W power level requires 4.75 V or higher; 500 mW requires 3.0 V or higher; 100 mW, 10 mW and 1 mW require 2.8 V or higher.
Default calibration data in flash. This is caused if the module-specific power calibration data is either not present or is invalid, or if none of the
6
parameters have been modified from their default values. Power levels may be incorrect.
Default configuration parameters in flash. This is caused if the user-modifiable parameters (i.e. those stored by a 'WR' command) in flash are
all the compiled-in default values. This is caused if the user configuration is found to be not present or invalid at power-up and there is no user
custom configuration, or if no user-modifiable parameters have been modified from the compiled-in defaults. Note that modification of one or
7
more parameters without the subsequent ATWR to commit the changes to flash will not deactivate this warning, since it reflects the status of
the parameters in flash. Note as well that this warning does not reflect usage of the custom configuration defaults, only usage of the compiled-
in defaults.
Default factory configuration parameters in flash. This is caused if the factory parameters (i.e. those stored by a 'WP' command) in flash are
all the default values. This is caused if the factory configuration is found to be not present or invalid at power-up, or if no factory parameters
8
have been modified. Note that modification of one or more parameters without the subsequent ATWP to commit the changes to flash will not
deactivate this warning, since it reflects the status of the parameters in flash.
<Diagnostics> VL Command is used to read the
verbose firmware version of the RS-232/485
Modem.
Sample output: Firmware version 0.8, Apr 16
2004 10:46:57
<Diagnostics> VR Command is used to read the
firmware version of the RS-232/485 Modem.
<Diagnostics> WA Command reports the warning
numbers of all active warnings - one warning
number per line. No further information is shown
and warning counts are not reset.
Sample Output (indicates warnings 1 and 3 are currently active):
<Diagnostics> WN Command is used to report
detailed data for all active and sticky warnings.
•
Warning number & description
•
Number of occurrences since the last WN or WS command
•
Whether the warning is currently active
Warnings which are not currently active, and have not been active since the last WN or WS
command, are not displayed. WN Command also resets all non-zero warning counts, except for
warnings that are presently active, which are set to 1.
Sample output:
Warning 1: Under-voltage
Warning 4: Over-temperature
RS‐232/485 RF Modem Product Manual – MAN0782‐02
3 occurrences; presently active
5 occurrences; presently inactive.
