5. The RS232 interface
The column gauge is equipped with an RS232 interface to support the output of measurement data to
computers, multiplexers, statistic printers and so on. The
“RS232” connector is located on the IMB-mc1
at the rear of the column gauge. Transmission and data formats are according to Opto RS232 .
5.1 Transmission format and wiring
Baud rate : 4800
Start bits : 1
Data bits : 7
Parity : EVEN
Stop bits : 2
Handshake : OFF
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>”
Meas. values outside of measuring range “OV <cr>”

Selection of gauge
C1 ... C8
Request type of device / version: "C200 V1.0 < cr > "
Start / Stop dynamic measurement
Executes zero adjustment
Note : This command cannot be used to execute a gauge calibration with two masters
Simulates the actuation of foot / hand switch at Ft1 port
Simulates the actuation of foot / hand switch at Ft2 port
Simulates the actuation of foot / hand switch connected to the IMBus
Status request of foot / hand switch inputs as well as encoder button :
e.g.
"0 1 0 0 <cr>"
( ’0’ = not actuated; ’1’ = actuated )
Status of foot / hand switch connected to the IMBus
Status of foot / hand switch at Ft2 port
Status of foot / hand switch at Ft1 port
Status of encoder button
Note : The commands are only executed, if the menu MEASURING has been selected.
All characters set in inverted commas ( e.g. "? <cr> " ) are transmitted in ASCII format.
