Replacing the apC/L EPROMs
When Sensormatic updates an apC/L EPROM, you may need to replace
the EPROM at your site. If your panel is equipped with flash EPROMs
and the host supports flash downloading, firmware updates and
enhancements are made through the host. You will not need to replace
EPROMs.
For FlashROM, follow the instructions provided with the software.
To replace the apC/L EPROMs:
1. Remove power from the apC/L.
2. Using an IC extraction tool, carefully remove the EPROMs from
sockets U9 and U10.
3. Place the new U9 EPROM in the U9 socket. Place the new U10
EPROM in the U10 socket.
4. Carefully check the orientation of the EPROMs. The notch on the
EPROM should be placed toward the top of the apC/L module.
Ensure that all legs fit into the socket correctly.
CAUTION
EPROMs are sensitive to electrostatic discharge.
Change the EPROMs only when wearing a
grounding wrist strap.
Note EPROMs fit into the socket differently, depending on the size of
the EPROM. The legs of EPROM 27C512 (28 pins) do not fill
every hole in the socket. Leave the top two rows of holes open.
The legs of EPROM 27C1024 (32 pins) fill the entire socket.
Figure 2.3 shows this difference.
