APPENDIX E: CHANGING THE OMP-MODL
EPROM
The EPROM (Erasable /Programmable Read Only Memory) contains the software
code which controls the function of the OMP-MODL. Updates to add features and/or
improve performance are sometimes performed on the OMP-MODL by changing the
EPROM to a later version. If desired, contact Omega Engineering, Inc
Service/Repair Dept. about performing the upgrade. When a replacement EPROM is
received, use the following procedure to remove and replace the EPROMs.
CAUTION
The EPROM chip is especially sensitive to damage
from static discharge. Discharge body static before
working with the OMP-MODL and EPROM by
touching a grounded surface. Call with any
questions!
To change the EPROM chip:
1. Download any valuable data retained in OMP-MODL memory.
2. Turn off the OMP-MODL power
3. Remove the side retaining screws ( 4 ) holding the bottom plate
or ML-BATT module in place.
4. The EPROM is located in a socket near the end of the exposed
circuit board.
