Quick Reference Guide
The node ID (user address) is defined/modified in object 2101H or via LSS.
In addition it is possible to set the user address using
two rotary switches of the encoder (see TABLE 5.1). The max. set is 99.
If the switches are set at 0, at power on the encoder keeps as node number
the one stored in object 2101H; otherwise it keeps the one set with the
rotating switches.
The default set of the two switches is 00.
The encoder rear cap must be removed to gain access to two rotary switches, one 4-pin DIP switch and one 8-pin tap connector
(Picture 5.1).
).

BAUD RATE SETTING
CONNECTIONS
The bus and supply cables must be connected to the M12 connector as shown in the Picture 6.2 and in the TABLE 6.2.
The encoder should always be connected with shielded conductors. The cable shield should be in placed at both ends of the cable.
Connectors must be selected to permit a 360 degree contact of the shield . Ensure that no equalizing currents are discharged via the
shield. As the encoder is not always connected to a defined earth potential depending on its mounting position, the encoder flange
should always be additionally linked to earth potential.

The baud rate is defined/modified in object 2100H or via
LSS. In addition it is possible to set the
baud rate by means of contacts 1, 2 and 3 of the encoder
DIP switch (see TABLE 5.2).
If the switches relating to the baud rate are set at 0, at power
on the encoder keeps as baud rate the one stored in object
2100H; otherwise it keeps the one set with the DIP switch.
The default set of the DIP swicht contacts 1, 2 and 3 is: OFF
ON OFF.
Terminating resistor
If the connected encoder is the last device in the bus line, the
bus must be terminated with a resistor. The resistor can be
connected by the contact 4 of the encoder DIP switch (see
TABLE 5.2).
The default set of the DIP swicht contact4 is: OFF.
