10.4.2 Rotary coding switches S4 + S5 (serial interface)

These two switches can be read out through the Script command "Get
Destination)" and the value can be used for further functions. This value is read in when the
Gateway is switched on or always after a Script command has been executed. The switch
positions "EE" (testmode) and "FF" (config mode) are not possible for RS422- or
RS485-operation.
The switch position "DD" (ie, S4 and S5 in position "D") is reserved for internal
purposes, Firmware-Update Ext.-Board. The Gateway should only be switched
into this mode for a Firmware-Update. Otherwise the firmware of the extension
will be deleted and there is no access, respectively no function of the exten-
sion anymore.

10.4.3 Termination (CANopen)

If the Gateway is operated as the first or last physical device in the CANopen, there must be a
bus termination at this Gateway. In order to do this, either a bus terminating resistor must be acti-
vated in the connector or the resistor (220 ) integrated in the Gateway must be activated. In
order to do this, slide the slide switch to position ON. In all other cases, the slide switch must
remain in position OFF. Please refer to the general Fieldbus literature for further information on
the subject of bus termination.
Note: To activate or deactivate the bus termination, please remove the BUS-connector and care-
fully set the switch to the desired position.
