Cable specification
Cable type: Unshielded cable
Cross-section
The actual permissible wire cross-section is specified by the electrical condi-
tions of the connected equipment an the female connectors used:
●
Max. load current and required heat dissipation through the connected wire
at maximum ambient temperature.
●
Permissible voltage drop for error-free operation of the connected equip-
ment.

External interface (EXT0)
The external interface EXT0 is used exclusively for the connection of an RFID
module XE 020/A. This is used for touchless identification of the user at the
operating panel. If the operating panel is equipped with an RFID module, it is
connected on leaving the factory via a shielded connecting cable to the EXT0
interface of the operating panel.
5.5.1
Cable specification
The connecting cable for the RFID module XE 020/A is also available as re-
placement part, see
chapter 3.6.1 "Ordering information" on page 19
.

RS-485-A interface (SI0)
When using a CPU module as RS-485-A master, the SI0 interface for the con-
nection for max. 3 RS-485-A slave participants, such as Input/Output module
(OI 3xx) or keypad module (XE 040/x) etc. can be used. For multiple bus par-
ticipants, the bus terminating resistor for the last participant must be activated.
The activation of the but terminating resistor is done using DIP switch or ter-
mination bracket.
But termination via DIP switch
If the operating panel is the last participant, the bus terminating resistor for the
RS-485-A interface is to be activated. To do this, the DIP switch is set to ON
or the termination bracket is to be realized (see
).
Addressing
An addressing occurs via the DIP switches 1 and 2 on the back side of the
operating panel. The operating panel used the address 0x10h in the delivery
state. Other devices connected to this interface cannot be operated with this
address.
