8.8.18 Command: Set HF read/write head address
NOTE
The command is only available in HF bus mode.
Only one single bus-compatible read/write head can be connected to the interface
during command execution.
Deactivate read/write heads before manual addressing via the parameter data so
that automatic address assignment is not executed.
The Set HF read/write head address command can be used to set the address of bus-compat-
ible HF read/write heads. Command execution is independent of the activation of or the ad-
dress set for a read/write head. Any existing read/write head addresses are overwritten.
Permissible values are 1, 2…32, 68.
NOTE
68 is the default address of the read/write head.
A bus-compatible read/write head with this address cannot be activated.
If a non-bus-compatible read/write head is connected, the device outputs a fault signal.
See description of the output data, p. [}105].
