IV. Commands via the serial interface (RS422 protocol)
All commands have the following structure:
<STX><Command><[Data]><EOT>
All commands are answered by Fx9xILA as follows:
<NAK>
= the command was not recognised or the data is outside the limit values.
or
<ACK>
=
the command was recognised and executed, the command requires no return data.
or
<Data> =
the command was recognised and the requested data has been sent.
Definitions:
STX
= start transmission = 02h = CTRL B
EOT
= end of text = 04h = CTRL D
NAK
= no acknowledge = 15h = CTRL U
ACK
= acknowledge = 06h = CTRL F
Command
= 3 digit command (ASCII text)
[Data] = whole numbers (ASCII text)
In ASCII text (data) spaces and capitals/small letters are ignored.
