Connecting Read/Write Heads for the HF Bus Mode

3
The maximum permissible length of the bus is 50 m.
The following accessories are required for the bus mode:
The VT2-FKM5-FKM5-FSM5 (Ident-No. 6930573) junction boxes are required for connecting
n
several read/write heads to an RFID port
RSE57-TR2/RFID bus terminating resistor (Ident-No. 6934908)
n
Optional: VB2-FKM5-FSM5.205-FSM5.305/S2550 junction box (Ident-No. 6936821) for feed-
n
ing in an additional power supply
RFID connection cables (e.g. RK4.5T-0.3-RS4.5T/S2503)
n
„ Connect the read/write head as per the figure below. The maximum length of the spur
line is 2 m.
„
Take the power supply into account, particularly at switch-on (see data sheet), as well as
the maximum current carrying capacity of the lines (4 A).
„ Take the voltage drop on the line into account. If necessary provide an additional power
supply between the read/write heads using junction box VB2-FKM5-FSM5.205-FSM5.305/
S2550.
„ Connect a terminating resistor (e.g. RSE57-TR2/RFID) behind the last read/write head.
