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.
10.4 Switches
The Gateway features 7 switches with the following functions:
Termination Rx 422
switchable Rx 422-terminating resistor for the serial interface
Termination Tx 422
switchable Tx 422- or RS485-terminating resistor for the serial inter-
face
Rotary coding switch S4
ID High for serial interface i. e. configmode
Rotary coding switch S5
ID Low for serial interface i. e. configmode
Termination (CANopen)
switchable CANopen-terminating resistor
DIP-switch
Node-ID and baud rate
CANopen-Termination
switchable CANopen-terminating resistor (application side)
10.4.1 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.
