Connect the data cable to the J2 serial port.

Connect the remote antenna cable, if used.
4.
Connect the power cable to the J4 connec-
tor. Make sure you don't reverse the polarity
when you're attaching the cable. The cable
wire with the in-line fuse is the positive or
"hot" wire. It is always connected to a posi-
tive terminal.

PLGR…
F
ried eggs are good. So are fried chicken
and fried green tomatoes. But fried J2 and
J4 connectors on your AN/PSN-11 preci-
sion lightweight GPS receiver (PLGR) are
not good!
But some of you must think they are,
because a lot of J2 and J4 connectors are
turning up fried!
'Course, a fried J2 con-
nector usually means internal damage, too.
The problem comes when you connect or disconnect the PLGR from an external
power source. The right connection or disconnection means your PLGR will live to
receive another day. Get either one wrong and you'll be eating the cost of a fried
PLGR, along with crow, for lunch. The key is in the connection sequence.
Here’s the
right
way to connect a
PLGR to an external
power source…
1.
Make sure the PLGR and the electronic
device you connect it to have a common
ground before you connect the power.
The PLGR grounding wire should be
attached to the same battery post as the
ground wire that runs from the vehicle to the
vehicle's battery.
Some PLGR installations involving com-
puters have a special ground. If that's the case
with your equipment, make sure this step
includes that ground.
Keep in mind that if you remove the PLGR from the power cable instead of the
power cable from its external source, you still have a hot power cable!
If you need a new power cable, get it with NSN 6150-01-375-8661. If you need
a fuse for the cable, order it with NSN 6150-01-382-1551.
Finally, don't forget to remove
the BA-5800 battery from your
PLGR before you connect to an
external power source. A BA-5800
left in a PLGR getting external
juice will overheat and explode or
melt the battery case of the PLGR.
