The RS-232 interface
General notes
3.1
• 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:
Start of Frame (SOF)
Address 1 number 0...8,
for RS232 always 0
NO CHECKSUM!
Telegram (sensor response) sent from the sensor to the control:
Start of Frame (SOF)
Address 1 number
0...8, for RS232
always 0
For examples refer to chapter "3.8 Examples".
