Compatibility (Old memory cartridges in newer IDEC SmartRelay
modules)
... to earlier versions (FL1C and FL1D devices):
Data written to the memory cartridge in the FL1D can be
read in all FL1E. But data written to the memory cartridge in
the FL1C cannot be read by the FL1E. When the memory
cartridge is read by the FL1E, the original data in the FL1E
is deleted. Data cannot be written from the FL1E to the
memory cartridge.
... to earlier versions (FL1A to FL1B devices):
A memory cartridge that contains data written in earlier
versions (FL1A...FL1B devices) cannot be used in IDEC
SmartRelay devices of the FL1C and later generations.
When the IDEC SmartRelay system detects such an ’old’
memory cartridge, the message “Unknown Card / Press
ESC” is output to the display.
Vice versa, a FL1C or later memory cartridge cannot be used
in IDEC SmartRelay devices of the FL1A...FL1B family.
Compatibility (New memory, battery, or combined memory/
battery cartridges in older IDEC SmartRelay modules)
The FL1E memory cartridge can be used in FL1C or FL1D
devices but cannot be used in FL1A..FL1B devices. Data
written to the FL1E memory cartridge in the FL1C cannot be
read by the FL1E. When the memory cartridge is read by the
FL1E, the original data in the FL1E is deleted.
A FL1E Memory cartridge or FL1E Memory/Battery cartridge
that already has FL1E circuit program stored on it cannot be
used in any device other than FL1E device.
A FL1E Battery cartridge or FL1E Memory/Battery cartridge
can only be used in FL1E devices.
Upward compatibility of circuit programs
Circuit programs written for the previous versions
FL1A...FL1D can be transferred to FL1E units from
WindLGC.
