RES-409
Version 1
All controllers manufactured up to January 2007:
Various baud rates can be set for the CAN bus with DIP switches 6 to 8. The switch positions for the available
baud rates are shown in the table below:
9.2.6
DIP switches for setting the identifiers
A new DIP switch setting does not take effect until the next time the controller is switched on.
All controllers manufactured as of February 2007:
The 8-pole DIP switch determines the 8 high bits of the 11-bit long standard CAN identifier. The 3 low bits are
fixed. Since the identifier 0 must not be used, a maximum of 253 different controllers can be addressed in a CAN
network.
The least significant identifier bit has a fixed value of 0 for receiving CAN messages:
The least significant bit has a fixed value of 1 for sending CAN messages. The identifier for CAN messages sent
by the RES-409, in other words, always has a value one higher than for received CAN messages.
All controllers manufactured up to January 2007:
Switches 5…1 of the 8-pole DIP switch determine the 5 high bits of the 11-bit long standard CAN identifier. The 6
low bits are fixed. Since the identifier 0 must not be used, a maximum of 30 different controllers can be addressed
in a CAN network.
