The asynchronous serial interface is normally used to transfer data to a printer or to other
devices having a SLAVE function.
The transmission parameters are fixed and they are the following ones:
-
SPEED OF TRANSMISSION 9600 BAUD
-
DATA LENGTH 8 BIT
-
ONE STOP BIT
-
NO PARITY BIT
CONNECTOR RS-232

The SLAVE needs to have the same parameters.
If the digital readout has the serial output, each pressure of the
key will start the
transmission.
Data have the following format:
=DIGITAL READOUT=
AXIS X: 223.99
UNIT : MM
Instead of printing the label, it is possible to request the readout to send the positions
displayed. The request has to be made in ASCII mode on the serial line as follows:
“Q” + CR + LF
Answers, that is, the position values (e.g. 5708.65), have the following format:
“ 5708.65” + CR + LF
where
CR
=
CARRIAGE RETURN (0Dh)
LF
=
LINE FEED (0Ah)
