5. RS232 interface
The column gauge has an RS232 interface to support data output to computers, multiplexers, statistic
printers and so on. The plug connector ( 9-pin Sub-D ) is mounted at the rear of the column gauge and is
marked
RS232 .
Data transmission and data format according to Opto RS232
5.1 Transmission format
Baud rate : 4800
Start bits : 1
Data bits : 7
Parity : EVEN
Stop bits : 2
5.2 Data format
The data format has a fixed length of 10 digits including the end character <cr> = ASCII 13.
The measured value always starts with a sign ( +/- ) followed by leading zeroes.
The decimal point is shifted according to the unit and the resolution chosen.
Unit Resolution Data format
mm 0.0001 mm "± 012.3456 <cr>"
mm 0.001 mm "± 0123.456 <cr>"
inch 0.00001 inch "± 01.23456 <cr>"
inch 0.0001 inch "± 012.3456 <cr>"
When the measurement values are out of range "OR <cr>" is sent to the output device by the column
gauge.
5.3 Requesting measured values
The column gauge supports both data request variants of the Opto RS232 interface.
1. Data request via handshake lines ( unidirectional Opto RS 232 )
