•
Flashes rapidly (50 ms on, 50 ms off): FIND function is active
•
Lights up for 100 ms: Data is sent via REMOTE CAN BUS
•

Briefly flashes every second for 100 ms: normal operation; no data transmission
Configuring the CAN baud rate
The CAN baud rate can be configured using a UCC1 USB-CAN CONVERTER. For DPA output
stages with firmware version 1.4.0 or higher, the baud rate can also be displayed and
configured directly on the front of the device.
Displaying the CAN baud rate
To display the CAN baud rate, press the FAULT button and keep the button pressed down for
at least one second. The PROTECT, REMOTE, and STANDBY LEDs then display the set baud
rate for two seconds. Please refer to the following table for details.

Changing the CAN baud rate
Notice!
The CAN baud rate can only be changed if the CAN address is set to 00.
To change the CAN baud rate, perform the following steps:
1.
Press the FAULT button and keep the button pressed down for at least one second. The
PROTECT, REMOTE, and STANDBY LEDs then display the set CAN baud rate for two
seconds. Please refer to the section entitled “Displaying the CAN baud rate” for more
information.
2.
As soon as the CAN baud rate is displayed, release the FAULT button.
3.
Briefly press the FAULT button to switch to the next-higher CAN baud rate. The LEDs
indicate the new setting.
4.
Repeat step 3 until the desired baud rate has been set. (Example: To change the baud
rate from 62.5 kbit/s to 20 kbit/s, press the FAULT button exactly five times, i.e. 62.5 >
125 > 250 > 500 > 10 > 20).
5.
The new CAN baud rate is applied two seconds after the last time that the FAULT button
is pressed.
