Hardware ports, switches and LEDs

11.3.3 LED "Power"

This LED is connected directly to the (optionally also electrically isolated) supply voltage of the
serial interface (RS232/422/485).

11.3.4 LED "State"

Lights green
Flashes green
Flashes green/red
Lights red
Flashes red

11.3.5 LEDs 1 / 2 / 4 / 8 (Error No. / Select ID)

If these 4 LEDs flash and LED "State" simultaneously lights red, the error number is displayed in
binary notation (conversion table, see Annex) in accordance with the table in chapter "Error
handling". Additionally there LEDs are controllable via Script.

11.4 Switches

The Gateway features 6 switches with the following functions:
Termination Rx 422
Termination Tx 422
Rotary coding switch S4
Rotary coding switch S5
Termination (DeviceNet)
DIP-switch

11.4.1 Termination Rx 422 + Tx 422 (serial interface)

If the Gateway is operated as the physically first or last device in an RS485-bus or as 422, there
must be a bus termination at this Gateway. In order to do this the termination switch is set to posi-
tion ON. The resistor (150) integrated in the Gateway is activated. In all other cases, the switch
remains in position OFF.
Please refer to the general RS485 literature for further information on the subject of bus termina-
tions.
If the integrated resistor is used, please allow for the fact that this also activates a pull-down
resistor (390 ) to ground and a pull-up resistor (390) to VCC.
At RS48 only the Tx 422-switch must be set to ON.
The Rx 422-switch has to be on OFF.

11.4.2 Rotary coding switches S4 + S5 (serial interface)

These two switches can be read out through the Script command "Get (RS_Switch,
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.
