Factory settings of the digital outputs:
The digital outputs are initialized with 0.
USR 1 LED and USR 2 LED are switched off.
5.1.5 Control of the analog outputs
The analog outputs of the CANio 500 are controlled with the following CAN
message:
CAN identifier
Data field (length = 8)
Byte 0/1
Byte 2/3
Byte 4/5
Byte 6/7
0x300 + node number of the
CANio 500

Only bits 0-11 are relevant for the value of an analog output. Bits 12-15 are
ignored.
No check or conversion of the values is done. The received value is written
directly to the analog output.
The resulting voltage on the output depends on the configuration of the analog
output and is described in chapter 4.5.
