Command "I": Calling for Information
Description: This request is about the identity number of the device and the version of the firmware.
Example:
The message sent from the
Message
<STX> <TYPE> <ADDRH> <ADDRL>
Answer
<STX> <TYPE> <ADDRH> <ADDRL>
5.3 Switch ing commands
The switching commands refer exclusively to the input and output involved. The
other input and the other output are not affected!
These messages are processed in a straight forward way. The control character <STX> and the <TYPE>
field are passed on immediately. Each recipient analyzes the content of the <TYPE> field . If the type
does not match (e. g. the recipient is a member of the class d) the message is passed through.
Otherwise if the type does match, the <ADDRH><ADDRL> fields are evaluated.
Again, if the address does not match the message is passed through. But if the address does match, and

In the status register, the correlated bits

On the device, the LEDs of the inputs indicate whether a signal is present or not, whereas the LEDs of
