E-4 Replacing SmartPAC 2 PC Board
10.
Remove the Battery Backed Up Ram chip (U105 in Figure E-1) from the original board
and install it in the replacement board. This chip holds all your tool data.
11.
If your replacement board was shipped without a Boot Loader chip (U124 in Figure E-1),
you must remove the Boot Loader chip from your old board and insert it into the
replacement board.
12.
Make sure that the Input Check switch (S101 in Figure E-1) and the Master/Slave and
High/Low speed jumpers (J101 and J102 in Figure E-1) are in the same position on the
replacement board as they are on the old board.
13.
Install the replacement board in the enclosure, or on the mounting plate if your unit is a
panel mount, reusing the nuts and standoffs you removed in step 5 and tightening them
down with the ¼-in. nut driver. Refer to Figure E-1 for correct placement of nuts and
standoffs.
14.
Reinstall the ProCamPAC and DiProPAC PC boards, if necessary, in their proper locations
on the SmartPAC 2 board.
15.
Plug all the connectors you removed in step 3 back into the SmartPAC 2 board, including
connectors on the ProCamPAC and DiProPAC boards (if installed). Make sure to insert
the display connector (J115 in Figure E-1) into the SmartPAC 2 board with the correct
orientation.
16.
Double-check to make that sure all connectors are plugged into the correct slots.
To remove the Battery Backed Up Ram chip:
1. Place a small, flat-blade screwdriver between the Boot Loader Chip (U124 in
Figure E-1) and the bottom of the Battery Backed Up Ram chip. Make sure the
screwdriver is in contact with the chip itself and not with the chip socket.
2. Using the Boot Loader Chip as a fulcrum, gently pry up the Battery Backed Up Ram
chip with the screwdriver until the chip begins to move. Then, grasping the chip firmly at
both ends, pull it upward until it comes free. Be careful not to bend the legs of the chip.
Before replacing the Battery Backed Up Ram chip:
1. Make sure to inspect the legs of the chip. If any are bent, carefully straighten them,
using small needle nose pliers.
2. Line up the chip with the socket, making sure the notch or identification dot on the top of
the chip is aligned with the notch or identification dot on the socket. Then push the chip
in evenly until it is fully seated.
Use a flat blade screwdriver or an IC puller to remove the Boot Loader chip. Make sure
that the notch on the chip lines up with the notch on the socket.
