EEPROM Memory Module
All EDI-120 retrot control systems come equipped with a removable
EEPROM memory module located at the rear of the EDI-120 chassis. The
EEPROM memory module inserts into the on-board connector located at the
rear of the EDI-120 chassis. The EEPROM memory module is primarily used
to backup important conguration settings, and may be removed for safe
storage.
If a rmware update is required, Johnson Systems Inc. may supply an
EEPROM memory module with the latest rmware version. The rmware
EEPROM memory module can be inserted into connector, and the rmware
can be loaded into the microcontroller.
Refer to menu items “EEPROM”, “FW-LOAD”, “RESTORE” and “BACKUP”
on page 29 to 31 for further details.
NOTE: Be sure to “BACKUP” the EDI-120 when installation conguration is
complete.
