SSE Configuration Changes
The SSE configuration must be maintained on the JFORCES computer as
well as the SSE computer.
Note that the radio loads the configuration during power-up. This
means that any time you make parameter changes, you need to power off
the radio and the SSE computer before the changes take
effect. If you have the JFORCES SADL interface up and running, you will
need to stop JFORCES and re-start it.
On the JFORCES computer, the items to maintain are found in the
/data/sadl/sadl.cfg file, which is manually edited. The SSE
configuration parameters are listed as shown below. The lines prefaced
with a '#' are comments; and for these fields they describe the
options available for the following field:
# Power level: 0=Undefined, 1=.4 watts, 2=3w, 3=20w, 4=100w
# Id: 0 - DEM/VAL, 1 - SCU3+/SCU4, 2 - SCU4.2/SCU5E1/SCU5, 3 - Reserved
# guard_chan: 0-9
During testing, the only item observed that may require updating is
the F283_GUARD_CHAN (which varied between 6 and 7).
At present, the callsign is hardcoded ('ACMI'), as is the RSID
To review the configuration settings: with SSE up and running,
ESC from the SSE Main display to go to the
Functions menu. If you do not make any changes, just ESC
out of the sub-menu's (and don't ENTER from the OK or RECORD
At this point, the Position items (3.) are not
maintained since they are transmitted via the data port, and the SSE
computer's data port is not hooked up to the radio (just the JFORCES
computer maintains that connection).
RSID: (page 4-64) needs to be coordinated with Avionics. We
may be sharing RSID 1000 with their maintenance computer/radio - if
they have their SSE up, there will be a conflict and the aircraft
may not 'see' us until Madison's radio is out of range.
change, from the Functions menu,
- select Setup/Test,
- move the cursor down to Set SSE RSID
- enter the new RS ID
- move the cursor down to OK
- and ENTER to save and exit
- Frequency (ref: page 4-60). We currently have the
Frequency set to HI. Choices are: LO (.4 watts), ML (3w), MH (20w),
HI (100w). This should correspond to the JFORCES sadl.cfg parameter:
F283_POWER_LEVEL. To change, from the Functions menu,
- select Freq/Power Setup
- the cursor is on Power; press the SPACEBAR to toggle
through the options. ENTER will move the cursor to the next field.
- Leave HOP OFF.
- Set CHANNEL to the value provided by Madison. Enter the
Channel number (a '6' will result in channel '66', '7' in '77',
- Leave INS Comp: OFF.
- press ENTER to move the cursor down to RECORD and ENTER
again. Lower right box should display 'lib recorded' in response.
- ESC to return to Setup/Test menu.
Position (page 4-66). To check or change, select
Setup/Test, and go to the Set SSE Position
sub-menu. The ACMI building would look like:
- Latitude: 43 56 6 N
- Longitude: 90 15 6 W
- Alt (Ft): 908
- Call Sign: ACMI
- be sure to select OK (and ENTER) to save.
(Note that these values may be empty (Lat: dd mm ss N, Long:
ddd mm ss W, Alt: 0, Call sign: SSE), as JFORCES will post the
VERIFY NET PARAMS: (page 4-60) If you go into the Show Rx
AA Data display in Setup/Test, it will show you SSE
Position, Mode, Channel, Air Key, Gnd Key, Net Shape, and A/C
ID. The only ones you can change are the SSE Position values
and Channel via Freq/Power Setup. The other fields are
hardcoded by SSE or via the KOK13/Czy-10. The display should look
- Mode: AG Chl: 66
- Air Key: 01
- Gnd Key: 00
- Net Shape: 44
- A/C ID: NOT 43
The SSE computer and radio almost always need to be power-cycled in
order for changes to take place, so I would recommend that once you've
made any configuration changes, shutdown the SSE computer and radio
(using the power strip switch), wait a few seconds, and power them up
