CR10 PROM Replacement Procedure
This document will walk you through the procedure for replacing the firmware (PROM)
in a Campbell Scientific CR10 Measurement and Control System. If you prefer to have
Campbell Scientific install the PROMs (for a nominal fee), request a Returned Materials
Authorization (RMA) from Campbell Scientific.
This procedure erases data and programs stored in the CR10.
Before you begin, transfer all data and programs you wish to save
to a computer or storage module. For information about trans-
ferring data and programs between the CR10 and a computer, see
the CR10 Operator’s Manual.
To prevent components from being damaged by the discharge of
static electricity, the PROMs should be replaced at a grounded
work station by a person wearing a grounding strap.
Tools Required
• Phillips screwdriver #1
• PROM puller
or
Flat-blade screwdriver (shipped with CR10)
• New PROM

6. Pull the control module forward to
separate it from the wiring panel
(Figure 3).
7. With a Phillips screwdriver, remove
from the control module the two
screws on the side opposite the con-
nectors (!on Figure 4).
8. Pull the end cap away from the con-
trol module and expose the RF shield
("on Figure 4).
9. Lay the control module on a flat sur-
face (e.g., table) and push the RF
shield with your thumb while grasp-
ing the can to remove the circuit card
from the can (Figure 5).

CR10 PROM Replacement Procedure
10. See Figure 6 to locate the PROM on
the CR10 CPU board. The installed
PROM has a notch on the left side
when the CPU board is oriented as in
Figure 6. The replacement PROMs
must also be installed with the notch
on that side.
11. Use a PROM puller to remove the
PROM. If you don’t have a PROM
puller, use the less elegant procedure
described below:
a) Insert the end of a small flat-blade
screwdriver underneath the
PROM, then gently rotate the
screwdriver to slightly lift the
PROM from the PROM socket (!
on Figure 7).
b) Gently pry up the end of the
PROM to about 1/8” off the
socket ("on Figure 7).
c) Move the screwdriver to the
other end of the PROM and per-
form the same procedure (#and
$on Figure 7).
d) Alternate prying the PROM from
either end. Lift the PROM
approximately 1/8” with each
pry until the pins clear the sock-
ets and the PROM can be lifted
out of the socket.
12. Hold the new PROM by either end as
shown in Figure 8. Position the
PROM over the sockets with the cir-
cular notch on the end of the PROM
oriented the same direction as the sur-
rounding PROMs.

The notch must be on the correct side. Inserting the PROM in the
wrong direction can damage it.
Set the pins of the PROM on the
sockets and press gently. Make sure
individual pins are being inserted
straight into the socket clips and are
not bending. Gently push the PROM
in until it seats fully in the socket.
Inspect the PROM assuring that none of the pins have been bent
or are not seated in their corresponding socket clips.
13. Repeat steps 9 through 1 (in reverse
order) to reassemble the CR10.
