3 The RS-232 interface

3.1

General notes

• Step 1: Setting of the sensitivity mode A-D; Step 2: Teaching of the Scanning range

• In measuring mode: Yellow LED flashing = weak signal received. Conceivable corrective measures: teach

object anew; move object closer to sensor; clean transducer.

• In measuring mode: Red LED on = object within blind range

• Provided the Teach-in sequence cannot be successfully completed the sensor defaults automatically to the

previously saved settings.

• Power must be switched off before connecting the sensors.

• A soiled beam columnator may generate erroneous output signals. Therefore it must be checked from time

to time and cleaned if necessary.

• Via the RS 232 interface measured data can be received and a number of functions are configurable.

• The sensors work with a baud rate of 115’200

3.2 Structure of commands

All commands consist of ASCII characters only. One character consists of 1 start-Bit, 8 data-Bits and 1 Stop-

Bit.

Address

Address „0“ is the broadcast address, which is accepted by every sensor and which must be used when

using RS232.

Telegram sent by the control to the sensor:

{0AB}

NO CHECKSUM!

Telegram (sensor response) sent from the sensor to the control:

{0AB47}

For examples refer to chapter "3.8 Examples".
