(ID-related) The ID number for an individual product is stored in the EEPROMs (U7 for the TX module, U11 for the RX module) of each module (TX module: AXF7006, RX module: AXF7008). It should be noted that wireless communications cannot be performed unless these ID numbers are identical.
1. Replacement of the TX or RX module
Upon replacement of the TX (AXF7006) or RX (AXF7008) module, remove the EEPROM from the original module and mount it on the new one.
2. Replacement of the EEPROMs (U7 and U11)
Using service part AXX7169 (a kit containing two EEPROMs with identical ID numbers stored in them,) replace both EEPROMs when either needs to be replaced.
B
Note : The AXX7169 is a service part containing two EEPROMs, both of which must be replaced when either needs to be replaced.
