2.
Insert your card. To keep your
card securely in its slot, cushion
it by placing small or medium-
sized foam pieces inside the
top of the cap. Insert enough
foam into the cap so that
when you slide the cap back
onto the Field PC with little
pressure, a ¼ inch (6 mm)
gap remains between the cap
and the Field PC as shown.

3. Tighten the Communication Cap screws
until they are rmly in place. To properly
seal the cap, apply an extra ¼ to ½
turn after the screws become
hard to turn.

Universal and Optical Caps
1. Use a #1 Phillips screwdriver to loosen the captured top
screws on the Field PC. Remove the standard cap.
2. This section tells you how to insert your card(s) properly. For
memory cards, see step 3. For medium or large CF cards,
see step 4. For any other card types, insert your card(s) and
skip to step 5.
CAUTION: Before inserting a card, make sure the four

3. If you are inserting an SD or CF memory card, make it
easier to remove by rst placing a card pull tab onto the
card.
4. There are two types of CF cards: Type 1 and Type 2.
A Type 1 card is thinner than a Type 2, and requires
the use of a spacer. To insert a Type 1 card, hold the
spacer (shown below) to the front of the card while you
insert the card into the rear slot of the adapter.

5. Once the card is placed in the adapter,
carefully align the card with the large
slot in the Field PC. Ensure that the
arrow on the adapter plate is pointing
towards the screen side of the Field PC.

6. Once you have inser ted your card(s), hold it in place
while you tighten the adapter plate screws. Then
tighten the four small side
screws until the top of

medium-sized foam pieces. Insert foam pieces inside the top
of the cap to keep the device
in place. Stack enough foam
so that when you slide the cap
into place with little pressure,
a ¼ inch (6 mm) gap remains
between the cap and the Field
PC. This gap closes when you
secure the

step 6, rst press down on the cap
so the screws engage. To properly seal the cap, apply an extra
¼ or ½ turn after the screws
become hard to turn.
Note: Even if a small gap
remains between the

Mounting an External Device
Overview
The Field PC features a convenient cable channel that
hides cables attached to an external device you mount on
the Universal, Optical, or Data Acquisition Caps. External
devices might include an external RS-232 sensor (such as
a GPS receiver) or a USB device.
This section explains how to insert a cable in the cable
channel and how to mount the external device onto the
extended cap. These instructions assume you have already
installed your extended cap onto the Field PC.
1. Turn off the Field PC and
remove the extended cap,
bottom hand strap latch, battery
door, and battery pack. Leave
the serial adapter plate in place.
Carefully remove the four side
screws on the body molding
and slide off the body molding
about one inch (2.5 cm).

2. Thread the sensor cable along the cable
channel and out through the body
molding.
3. With the cable in place, slide
the body molding into place
and tighten the four side
screws. Replace the
battery pack, battery door,
and hand strap.

4. Connect the sensor connector to the 9-pin serial port or
USB host port.
5. Make sure the seal adapter plate is properly
installed.
CAUTION: The seal adapter plate must be
installed to seal the Field PC.
If you have not already installed the seal adapter
plate onto your Field PC, see steps 2–4 of the
previous section for instructions.

6. To give the cable an exit through the extended cap, cut
the thin rubber overmolding on the extended cap along
the entire scribe line using a razor blade or sharp knife.

7. Slide the extended cap onto
the Field PC and push the
sensor cable through the
incision you made so that
the cable exits out of the
top of the cable channel.
Note: The incision does
not affect the seal of the
Field PC.

8. Tighten the cap screws until they are rmly in
place. To properly seal the cap,
apply an extra ¼ to ½ turn after
the screws become hard to
turn.
9. Mount the sensor on the front of the extended
cap and secure it with a strap. Note: An optional
sensor mounting strap is available
for purchase.
