High-Performance Distance Sensor 3
1. Proper Use
High performance distance sensors which use the principle of angle measurement determine the distance be-
tween the sensor and the object. These sensors have small working ranges (under 1 m) and recognize objects
with high precision. Some sensors use a high-resolution CMOS line array and DSP signal processing. The color,
shape and texture of the objects to be recognized does not affect the sensors’ measurements. Even dark objects
can be reliably detected against a bright background. They can be operated with very high speeds or very high
resolutions. The measured value can be output as an analog value or via the interfaces. Furthermore, Teach-In,
filter functions for adjusting a switching output, and an error output are available. The measuring range can be
selected individually within the working range.

4. Installation Instructions
During use of the sensors, applicable electrical and mechanical regulations, standards and safety precautions
must be adhered to. The sensor has to be protected against mechanical influences.
In case of very glossy surfaces the sensor has to be mounted slightly inclined and has to be mounted on a
plane surface (approx. 5°), to inhibit a direct reflection of the laser beam into the optics.
5. Initial Operation
Please control the proper connection of all conductors.
Impress a supply voltage of 18…30 V DC with ripple of < 10 % (within the indicated voltage range).
The settings can be operated either with the RS-232 interface or manually.
6. Function
The sensor uses a high-resolution CMOS line array and DSP technology, virtually eliminating material, color
and brightness related measurement value differences. Alternatively high speed (Speed-Mode) or high
resolution (Resolution-Mode) are adjustable. Integrated analogue output can be configured for voltage
0…10 V or current 4…20 mA, error output and RS-232 interface, Teach-In, Error Output and filter functions.

Outputs
Analogue Output
The analogue output is connected to analogue earth. The analogue output can be configured as a current
output or a voltage output. If you have the choice we recommend the use of the voltage output (reduced cur-
rent consumption).
The analogue output reads out a standard signal of 0...10 V when configured as a voltage output (see settings).
The analogue output reads out a standard signal of 4...20 mA when configured as a current output (see settings).

Error Outputs
The PNP error output is switched to positive if no object is detected within the selected working range, or if an
error has occurred (e.g. an interrupted conductor at the current output). The red F LED lights up to indicate that
the error output has been activated.
RS-232 interface
This sensor is equipped with an RS-232 interface for communication with a device such as PC or a controller.
Sensor functions can be activated, and scanning results can be acquired via the RS-232 interface.

Optimize the exposure time
The exposure time is adapted automatically by the sensor. In the presetted DCM (Default Capture Mode) the
Sensor has a fixed maximal possible Exposure Time. It can be adjusted manually in addition in case of difficult
applications.
By means of the LCM (Long Capture Mode) the Exposure Time of the sensor can be elongated for dark or
highly glossy objects (e.g. black lack) in order to achieve a more exact measurement.
By means of the SCM (Short Capture Mode) the Exposure Time of the sensor can be reduced for dark or highly
glossy objects (e.g. black lack) in order to achieve a reduction of the drop down of the Measurement Rate.
The shining of the U-LED and the I-LED the current setting is indicated. DCM is preset in delivery status. By
pressing of the Plus respectively Minus key the current setting can be changed.

7.3. Settings and Queries via the RS-232 interface
The interface utilises a software handshake procedure (see protocol specification below). All sensor settings
can be selected digitally with a PC, and all values generated by the sensor can be read out at a PC.
The RS-232 interface connections RxD (connection 5, grey) and TxD (connection 4, yellow) correspond to mi-
nus (connection 3, green) and can be connected to the appropriate connections of the communication partner.
Software Tools:
Software for the interface of the CP08 is available. Download address: www.wenglor.com
Interface configuration:
Baud rate: 38.400 baud, 8 data bits, no parity, 1 stop bit
Plug connectors of the wenglor®Plug Adapter S232W3:
• 8-pin M12 plug connector for connecting the power supply and the outputs
• 8-pin M12 socket connector for direct sensor connection
• 9-pin M12 sub-miniature socket connector for direct connection to the RS-232 interface at the PC, or the
utilised controller
1) Connect the sensor over the wenglor®Plug Adapter S232W3 with PC, controller etc.
Installing the wenglor®Plug Adapter S232W3:
• Set the rotary selector switch Ýto RUN
• Disconnect the 8-conductor connector cable (S80-xx) from the sensor
• Connect the S232W3 plug adapter directly to the sensor
• Connect the 8-conductor connector cable (S80-xx) to the plug adapter
• Connect the 9-pin sub-miniature socket connector to the serial interface at the PC
• Switch the power supply on

Connecting the wenglor®sensor
to a PC or a controller
2) Procedure of the interface operation:
• Set the rotary selector switch Ýto RUN
• To enter or query the sensor settings use the interface commands according to the protocol. Every interface
command and every answer of the sensor starts with “/” (ASCII 47) and ends with “.”. (ASCII 46) In case of
an incorrect communication, the sensor emits a Negative Acknowledge character (ASCII 21). If a command
is not closed with “.”, the sensor remains in wait state and does not give an answer or error message.
• Even with continuous query it should be adhered to a pause of 10 ms between two interface commands.
• Because of the protocol a maximum of 100 measurement values per second can be emitted. In the case
of faster applications use the analog output.

xx = 00...99 for 1 to 99 measurements until the Error Output reacts in case of errors. The default value is 20.
Attention: The duration of cycles of the number of measurements depends on the exposure time, but the delay
time cannot be allocated.
Change baud rate
The baud rate of the sensor is standardized with 38400 baud. If you want to change the baud rate, proceed as
follows.
Open your hyper terminal and take the following settings: Baud rate: 38400, Data bit: 8, Stop bit: 1, Parity: none,
Flow control: none.
In order to change the baud rate, enter the following commands corresponding your desired baud rate.

Special queries
Query object distance binary
Differing from the usual query of sensor values via the protocol it is also possible to query the object distance
faster through binary data.
Send a “#” sign to the sensor, then the currentjy measured distance value is emitted in a binary form.
