The 3 dip switches in the middle of the board is in the same positions?
Do only change the eeprom? Is the software eprom the same version?
If the boards are the same you should have a part no like this:
GXA21240D1 (This board is fully populated, all features).
D2-3-4 is partially populated, not all features. D3 is only for hydraulic elevators.
