Coding within the Sub−D plug
Via the 9−pin Sub−D socket of the CAN addressing module you can connect a coding plug
which defines baud rate and controller address of the basic controller.
In order to permanently set baud rate and controller address in the Sub−D plug, connect the
pins 1 to 8 to pin 9 in a certain way!

= connect to pin 9
Example:
Setting the baud rate to 50 kbaud
ð Connect pin 1 to pin 9 and pin 2 to pin 9 by soldering.
Setting the controller address
You can calculate the connections between the pins 4 to 8 and pin 9 required for setting the
controller address by using the values of the following table:
Value
Example:
Setting controller address 13
The sum of the values has to equal 13: 1 + 4 + 8 = 13
ð Connect pins 4, 6 and 7 to pin 9 by soldering.
