Status Data
When you send a command position to the Galvo Scanner, the status data will be sent from the Galvo
Scanner to the CK3W-GC Unit.
For details on the status data, refer to the Galvo Scanner specifications.
Parity bits are added to the status data.
In order to check that communications are in progress successfully, use a user program to check
whether the parity is correct.
