Registry entries that are modified manually during installation must also be set for remote arm entries that are indicated by _CMM2, _CMM3, & _CMM4. The values for these registry entries should be changed on the controlling computer (Arm1) for any settings that should be applied to other arms.
If you have a DEAWrist that is present on your Arm2 system, then you would need to set the DEAWrist option under Option_CMM2 to 1 on the your Arm1 system.
Some settings are modified automatically through software during installation, calibration, or other PC-DMIS processes. Manually adjusted registry entries are the ones that need consideration for multiple configurations.
