SADL Radio and Interface Initialization
The following contains instructions for starting JFORCES and the SADL
interface for Volk Field.
The JFORCES computer is a eData PC in a standard size tower, hostname =
'sadl1'. The 'SSE' computer is also an eData PC, distinguished by the
mini-tower box and a "P3-550" label.
Detailed instructions with illustrations for the SSE computer
operations can be found in the SADL SSE Maintenance Manual T.O.:
Situational Awareness Data Link (SADL)
Support Equipment (SSE) Part Number 5155750
Airborne Radio Set AN/ASQ-177C(V)4C
The crypto keys and the radio channel need to
be kept current with Madison Avionics.
- Wiring Connections
If the radio was removed to be rekeyed, there are 4 wires to
re-connect. Refer to the SSE Maintenance manual for illustrations.
All 4 connectors on the radio are unique, so you just have to match
the connectors. The other 'ends' should not be disconnected from
the computers. The 'front' of the radio is the face with the status
lights on it.
- power cord - 120VAC plug connects to the surge protector. The
other end attaches to the only connector on the side of the radio.
- Data cord (1) - attaches to a connector labeled J2 on the
top/back of the radio (the high-hat). This cord goes to the DB9
connector on the computer.
- Data cord (2) - attaches to the connector labeled J3 on the
front of the radio, the other end connecting the DB25 to the
- Antenna - attaches to the front of the radio (connector labeled
ANT - J2).
- Power On
To Power up the radio and SSE computer,
switch the power-strip/surge-protector (behind the radio) to On.
the SSE computer will automatically boot up - you will be prompted
to continue booting as an SSE boot or Windows boot. Use the SSE
boot - the timer/wait defaults to that, so you don't have to do
anything unless you're in a hurry.
- The Radio should immediately show:
- POWER light on.
- ALARM indicator light should come on for a few
seconds, then blink a few times and go off.
- OUT OF NET should be ON.
The SSE computer display should come up with the SSE program, and status
- URO OFF LATCHED,
- RS232 INACTIVE
- KOK Status: DOWN.
- SSE Computer Initialization
On the SSE computer display, the right column/center block
should show SSE Main.
- Press ESC to go to the Functions display.
- The cursor will be sitting on the Init SSE RS option
- press ENTER.
- The SSE computer will issue an initialization sequence to
the radio (the data will display in the bottom right), and after
a few seconds, the URO status should change to ON
- Press ESC to return to SSE Main. The SSE
computer display should come up with the a single box in the
left display window with a 1000 (our RSID
assigned/coordinated with Madison Avionics).
- FORCES Initialization
- login to the 'forces' user.
- click the JFORCES icon (or from an xterm, enter 'start').
- from System Controls, select a Simulation from
Start Scenario (any scenarion will do; example: 'test').
- 'Port 3000 will be Used' will pop up, press ENTER.
- as soon as the Master Controls Message Area turns blue,
select System Controls, Remote Interfaces,
Start SADL Interface. Click on Start SADL (which
defaults to a Live Feed).
- Once the SADL MONITOR dialog appears, select the Send
Data Via SADL, Send Position Data option. Given that
you have already saved position data that you want posted,
simply press Send All Data (then Dismiss).
- The radio's OUT OF NET will blink a few times and
then go off.
To some degree you can monitor I/O through SADL from an xterm
> tail -f /tmp/SADL_interface.log
...although I've found it to be marginal due to delayed
(optimized) I/O buffering.
When running a live feed, the SADL interface will always
record the session into a file stored in
/data/sadl/archives/. The /tmp/SADL_interface.log file will
indicate the filename when it starts, so you can refer back to
it later to run a playback.
When aircraft come into range, the main display on the SSE
computer will pop up boxes for each aircraft with their RSID.
- Upon completion, switch off the power strip to shutdown the radio
and SSE computer.
- FORCES/sadl1 can be brought down in the normal manner: select
System Controls, Kill MMI, "Do you really want to shut
down the entire current JFORCES application?" -- click on Yes
