Variable			Description

multitag	MOBY U/D or RF300; maximum number of MDS processed in parallel in the field. Permissible
	values: 1
field_ON_control	MOBY U: BERO operating mode; aerial field is switched on/off automatically. The command
	"Aerial ON/OFF“ is overlaid by the BERO operating mode.
	00 hex	=	Without BEROs; no reader synchronization
	01 hex	=	One or two BEROs;
			The BEROs are logically ored. While a BERO is operated, the field is
			switched on
	02 hex	=	One or two BEROs.
			The 1st BERO switches the field on and the 2nd BERO switches the
			field off. If there are 2 BEROs and one field_ON_time is parameterized,
			the field is switched off automatically if the 2nd BERO does not switch
			within the BERO time.
			If no field_ON_time is parameterized, the field remains switched on until
			the 2nd BERO is operated.
	03 hex	=	Activate reader synchronization by means of cable connection (refer to
			manual for Configuration, Installation and Service for MOBY U)
	MOBY D or RF300: 00 hex (reserved)
field_ON_time	MOBY U: time for BERO operating mode (field_ON_control = 02)
	00 hex	=	Time monitoring is switched off. For field switch-off, the 2nd BERO is
			needed.
	01 hex .. FF hex	=	1...255s switch-on time for the Reader field
	MOBY D: MDS type
	00 hex	=	I-code 1 (for example, MDS D139)
	01 hex	=	ISO MDS
	RF300: 00 hex (reserved)
reserved	Reserved
