High Power
Threshold
HPT= 5 bytes Command or Query.
This command allows the user to set the threshold for the high
forward power alarm/fault. If the forward power rises above the
specified value, the alarm/fault will be indicated. Setting this
parameter to 00.00 effectively disables the threshold.
HPT=xx.xx,
Where:
xx.xx = a real number between 48.00 37.00 and 64.00 57.00 dBm.
(Glenn note: This was wrong for the 1kW, it was 40-60 dBm.)
Example:
<1/HPT=56.00’cr’
>0001/HPT=’cr’’lf’
Default Value: 00.00

Initialize Events
Pointer
IEP= None Command only.
Resets internal pointer to allow RNE? Queries to start at the
beginning of the stored events log.
Example:
<1/IEP=’cr’
>0001/IEP=’cr’’lf’
IEP=
IEP?

Software Image IMG= 1 byte Command or Query.
Current Active software image,
Where:
1=Bulk Image # 1 currently active
2=Bulk Image # 2 currently active
Examples:
<1/IMG=1’cr’ (instructs the unit to load firmware from image #1 at
the next reset / power up).
<1/IMG?’cr’ (queries the image number that the firmware loaded
during bootup)
Note: If the user sends the IMG command, and then queries the IMG
value, the numbers may not be equal because the command
tells the firmware which image to boot from at the next bootup,
and the query reports the image that the firmware booted from
on the last bootup.
