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
F283_ID 1
# 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 ('1000').

SSE computer
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 prompts).

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).

  1. 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.
    To change, from the Functions menu,

  2. 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,

  3. 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:

    (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 data)

  4. 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 like:

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 again.
