7.0 O PERATION WITH OPTO-RS CONNECTOR
7.1 Operating modes
The dial gauge works in simplex mode: the displayed value is sent from the
instrument or requested from the peripheral equipment (pedal or request from
peripheral equipment). It can also be used with a duplex OPTO-RS connector. It
recognizes any command (ASCII character sent by the computer) as a request to
transmit the displayed value.
7.2 Inserting the OPTO-RS connector
Check that the connector is the right way round by
means of the polarizing slot. Insert the OPTO-RS
cable with the components facing the operator.
Neither the instrument nor the connector can be
damaged if the latter is inserted the wrong way
round.
7.3 Transmission parameters
4800 Bd, even parity, 7 data bits, 2 stop bits
7.4 Operation in simplex mode
• Transmission from the instrument: select reference mode, then momentarily
depress [set] to transmit the displayed value. The value is transmitted regardless
of the status of the LED of the OPTO-RS connector. If the LED is extinguished,
the display remains frozen until [set] is pressed again or a transmission request is
made by the peripheral equipment.
• Transmission request by the peripheral equipment: transmission of the
measured value can be requested from the peripheral equipment (printer,
computer) in measuring and reference modes, by sending any ASCII character or
by interrupting the LED for 140 msec.
See operating manual of optical connector for details.
7.5 Error messages
In the event of an error, the instrument sends the following message:
Measuring system error. Acknowledge by a data request or by
means of the [set] button.
