APPENDIX E
EPROM UPGRADE
If you receive an EPROM upgrade, you will need a screwdriver and an IC
DIP extractor or a pair of curved needle-nose pliers
1. Remove all power from the unit by placing the power switch to the 0
position and disconnecting the power supply from the outlet.
2. Remove the appropriate module by loosening the 2 straight slotted
screws that attach the module to the chassis, then pull the module out.
3. Refer to Appendix D (DS71 or DS71-MD2 module Mechanical
Layouts); locate socket U2.
4. Remove existing EPROM from socket U2 with IC extractor or
needle-nose pliers. Gradually loosen each side of the chip, alternating
pliers from side to side being careful not to bend chip pins.
5. Install the EPROM into socket U2. The EPROM is notched; the notch on
the EPROM should line up with the notch on the socket. Seat each pin
securely in its socket being careful not to bend chip pins.
6. By moving a hardware jumper, reset the DS71 or DS71-MD2 module to
default configuration status.
a. Refer to Appendix D (DS71 or DS71-MD2 module Mechanical
Layouts), locate Jumper JP4.
b. Jumper JP4 connects the two pins that are closest to the aluminum
face plate on the module. These pins are labled “RUN”.
c. Connect the two pins that are further from the face plate of the
module by moving Jumper JP4. These pins are labled “TEST”.
