DETAILED USER COMMANDS
The commands in this section may be used in two ways. First, you can
type only the command name to view the currently programmed data.
Secondly, you can set or change the existing data by typing the com-
mand, followed by a space, and then the desired entry. In the list
below, allowable programming variables, if any, are shown in brackets
following the command name.
ALARM
Alarm Summary
The
ALARM
command displays a summary of the radio's current oper-
ating condition. An eight-digit code will be presented which can be
decoded as described in “Major Alarms vs. Minor Alarms”.
AMASK [0000 0000-FFFF FFFF]
Alarm Mask
The
AMASK
command displays or sets which events cause an alarm
output signal to be active. Normally, the mask is
FFFF FFFF
, meaning
that any of the 32 possible events will activate the alarm output signal.
Entering the
AMASK
command alone displays the current setting of
alarm events in hexadecimal format. Entering the
AMASK
command
followed by an eight-digit hexadecimal number reprograms the speci-
fied events to trigger an alarm. The eight-digit hexadecimal number
used as the command parameter specifies 0 to 32 events that can
trigger the external alarm output. The hex value for the mask corre-
sponds to the hex value for the
STAT
command. Each bit that is a '1'
identifies an alarm condition that can trigger the external output. For
more information on configuring the alarm response, contact GE
MDS.
ASENSE [HI/LO]
Alarm Sense
The
ASENSE
command sets or displays the sense of the alarm output
at Pin 6 of the COM2 port. Entering the
ASENSE
command alone
shows whether the alarm output is active high or low. Entering the
ASENSE
command followed by
HI
or
LO
resets the alarm output to
active high or low.
