Appendix D – Device Compatibility Relevant Data
REVISION: 4.2
MANUFAC_ID: 574343
DEV_TYPE: 1100
DEV_REV: 4
TESTED USING THE FOLLOWING REVISION:
COMPATIBILITY_REV= 4
DEVICE COMPATIBILITY NOTE:
In case this device is replacing another device currently attached to the FF network, minimum impact on the
network and configuration is achieved if:
• The manufacturer ID (MANUFAC_ID) and device type (DEV_TYPE) of the replaced device are equal to
those of this device, (as defined in the device’s DD file) and
• The device revision (DEV_REV) of the replaced device is equal or less than the device revision of this
device, and
• The device revision of the replaced device as defined in the replaced device’s DD file is equal or greater
than the compatibility revision (COMPATIBILITY_REV) of this device
Example 1: DEV_TYPE 0x0001, DEV_REV 0x03, COMPATIBILITY_REV=0x01 means device can be used to replace
device revisions 0x03 - 0x01.
Example 2: DEV_TYPE 0x0001, DEV_REV 0x09, COMPATIBILITY_REV=0x05 means device can be used to replace
device revisions 0x05 - 0x09.
Even if minimum impact on the network is achieved, in all cases it still recommended to use the DD that exactly
matches the device’s DEV_REV and DD_REV.
Also, it is not recommended to use this procedure more than once without updating the host system DD files that
matches the DD_REV and DEV_REV of this device.
Example 1: DEV_TYPE 0x0001, DEV_REV 0x03, COMPATIBILITY_REV=0x01 means device can be used to replace
device revisions 0x03 - 0x01.
Example 2: DEV_TYPE 0x0001, DEV_REV 0x09, COMPATIBILITY_REV=0x05 means device can be used to replace
device revisions 0x05 - 0x09.
Even if minimum impact on the network is achieved, in all cases it still recommended to use the DD that exactly
matches the device’s DEV_REV and DD_REV.
Also, it is not recommended to use this procedure more than once without updating the host system DD files that
matches the DD_REV and DEV_REV of this device.

Since DEV_REV: 4 and COMPATIBILITY_REV= 4, it means that the revision 4 can only be replace another ICoT
with revision 4.
