MOBY U: Range limitation
Normal transmission power
MOBY D: HF power from 0.5 W to 10 W in increments of 0.25 W

MOBY U: BERO mode; automatic activation/deactivation of antenna field. The "Antenna ON/OFF"
command is superimposed by the BERO mode.

Description
Reduced transmission power
85 hex
Reduced sending capacity must be set when several
8A hex
write/read devices are positioned close together or
8F hex
when data memories which are located in the vicinity
91 hex
of a write/read device are detected later or not at all.
99 hex
Disadvantage: The field lobe becomes smaller and
9E hex
there is less time for communication or positioning
A3 hex
must be more precise.
No BEROs; no write/read device synchronization
One or two BEROs
The BEROs are logically ORed. The field is ON during actuation of
a BERO.
One or two BEROs.
The 1st BERO switches the field on and the 2nd BERO switches
the field off.
and
If two BEROs exist
a field_ON_time is configured, the field is
automatically deactivated if the 2nd BERO does not switch within
that BERO time.
If no field_ON_time is configured, the field remains on until the 2nd
BERO is actuated.
Activate write/read device synchronization via cable connection
(see manual for configuration, mounting and service for MOBY U)
Timeout monitoring is deactivated. The 2nd BERO is needed in
order to switch the field off.
1 ... 255s turn on time for the write/read device field.
