25-kHz TDMA DAMA
40. Change radio on/off switch to F2.
41. Load Orderwire Keys, LANT =
C5594 (positions 3-4), IO = C5596
(positions 1-2) (Input the same key
set in positions). Do not connect the
cable until the ANCD says “connect
to radio”. Cycle the radio to CT and
return to F2 if it continually fails to
load. Be patient.
42. Return on/off switch back to CT.
43. Go to Current Mode (1) and hit
enter.
44. Change mode back to DAMA; hit
enter.
45. Press Preset #1, hit the 1 key on
the keypad; hit enter.
46. Enter correct TK##; hit enter.
47. Hit enter to confirm the remainder
of the settings until SEND STATUS
B YES/NO appears.
48. Ensure antenna is connected at this
time, with antenna on azimuth to
satellite
49. At SEND STATUS B, select YES,
hit enter.
50. Select the service preset desired
(P01, P02, etc), hit enter twice.
51. Radio screen will blink, an arrow in
the right side of the screen will go
up and then down once or twice,
then see acquiring, then range,
then 25-kHz AC connected-SRVidle
52. NOTE: AD HOC DAMA WILL
ALLOW TBA-TO-TBA, TBA TO
MULTIPLE TBA, AND TBA TO
NETWORK CONNECTIONS.
53. Hit next to Service Setup (1),
select R (Routine), then enter the
TBA, MULTIPLE TBA’S, OR TO A
NETWORK ADDRESS enter time
required, hit enter and then Send,
enter.
54. Radio screen will show arrows on
the right going up and down and
then the screen will display 25-kHz
AC SRV-RX/TX (the station or
network called will change at the
same time).
55. Ready to talk as normal (be
patient).
56. To terminate setup, select
Teardown (2) THE CONNECTION
MUST BE TORN DOWN AFTER
COMPLETING TRAFFIC TO
AVOID INTERFERING WITH
OTHER STATIONS’ TRAFFIC.
57. Terminal will be in idle mode.
NOTE: To send data: (for
example, KL-43 or V-Mail) change the
V2400 to D2400.
NOTE: If the radio is not working
properly cycle the radio off/on several
times. Filter Tune does not correct all
as it did with older versions of radios!
38. Do not connect the cable until the
ANCD says “connect to radio”.
ERROR CODES = DO THIS
(PREVENTIVE MEASURE)
77 = Talk to net NCS. NCS needs
to check with Naples to insure the
TBA is on line.
82 = Check the TBA entered into
the radio to ensure it is correct.
(pmcs)
90 = This is a busy signal. Call
back later.
92 = Indicates conference call to
more than one terminal was made. At
least one terminal is not on the air but
others are.
Troubleshooting DAMA problems
Problem: Fail to get past 25-kHz
AC – Acquiring M – Idle when attempting
first connection after initial setup. No up
and down arrows displayed on the right
side of the screen.
Solution: Ensure the current
Orderwire key segment is loaded in fill
slots 1–4 in F2. Lack of the current
orderwire COMSEC loaded and/or not in
1 – 4 will cause a connection stop at the
25-kHz AC – Acquiring – Idle window
during initial connection.
Problem: Cannot get the Orderwire
COMSEC to load.
Solution: Do not connect the
ANCD cable to the radio until the ANCD
displays Connect ANCD to Radio. Press
the down arrow after connecting the
cable, follow on screen instructions.
Problem: COMSEC Alarm
continues to popup.
Solution: Refill keys in F1.
Problem: CTIC alarm.
Solution: Refill the orderwire key in
the correct positions – F2.
Problem: Data communications not
getting through but voice
communications are.
Solution: Run Link Test. It is item 7
in DAMA menu, needs to be run at 32
kbps, and the Symbol Errors need to be
less than 100 when transmitting data.
Takes about a minute to run and lets the
operator know a better signal is needed.
Info Code 93 appears, send back
information report and wait since
someone else is running the test.
