IPADS can communicate with a Forward Observer System (FOS). When connected to FOS, IPADS allows the
operator to import and export data from and to the FOS.
NOTE
Upon establishing communications, IPADS will synchronize its date/time to
the FOS current date/time. At any time thereafter, the operator can
synchronize the IPADS date and time to the FOS current date and time by
sending a request from the IPADS CDU.
FOS can request IPADS current position for transmission to AFATDS via
vehicle combat net radio.
From IPADS CDU the operator can send IPADS SCP data to the FOS for
subsequent transmission to AFATDS.
From FOS the operator can send a trig list of SCPs received from AFATDS
to IPADS.
a.
Connect IPADS to FOS using the W136 FOS cable assembly. Connect P1 to CDU J2 connector. If using
Handheld Terminal Unit (HTU) as FOS, connect W136 P2 to HTU J7. If using Rugged Handheld
Computer (RHC) as FOS, connect W136 P2 to RHC Com 1.
b.
Connect FOS to power and initialize it per the FOS operator's manual, TB 11-7021-228-10-1 or -2
depending on the platform.
c.
Verify that the FOS Status indicator (fifth field on the mode line) indicates FOS. If not, see paragraph 4-6,
Operator Troubleshooting.
d.
Once communications are established, the IPADS clock is automatically synchronized to the FOS current
date/time. If immediately after connecting IPADS and FOS IPADS time is not within one second of FOS
time, see paragraph 4-6, Operator Troubleshooting. To re-synchronize the IPADS date/time, perform the
following procedure:
(1) Scroll down to DATE/TIME on the MENU, then press ENTER.
(2) DATE / TIME page is displayed with the function key legends: F2-USE ALL, F5-GET TIME, and
F9-MENU.
(3) Press F5 to synchronize time. DATE / TIME page is displayed with INFO: FOS TIME DATA
RECEIVED on information line.
(4) Press F9 to return to MENU.
IPADS current position can be imported into FOS once IPADS has been initialized with position, paragraph 3-
12. To import IPADS current position, follow instructions in the FOS operator's manual, TB 11-7021-228-10-1
or 2, depending on the platform.
e.
To export SCPs from IPADS to FOS, perform the following procedure:
(1) Press F7 on the MENU, MAP, or NAVIGATION AID pages. POINT LIST page is displayed with
function key line: F2-NEW, F4-FILTER, F5-DEL ALL, F6-SND PNT, F7-SND ALL, and F9-EXIT.
CAUTION
If F5 (DEL ALL) is pressed, IPADS prompts PRESS Y TO DELETE
DISPLAYED POINTS; OTHER KEY TO CANCEL. Pressing Y permanently
deletes all points in displayed list.
