AR100 Operation Manual
3
Mount the sensor in such a way that the case is not twisted or warped. The
AR100 can be screwed on using two fastening screws
2.8. The fastening
screws are not included in the scope of delivery.
Attach the cable(s) 8-pin connector to the plug(s) on the rear of the sensor.
Connect the red () and brown (Ground) wires of the sensor cable
to a 9 to 36 volt DC power supply (or use the power supply if the sensor
came with one).
1.3.2
Serial Data Wires
The serial connection is required to set up a unit for operation. If not using
the Acuity Connectivity kit which includes a serial cable, the customer must
make their own D-sub 9 serial connector
1.3.2.1
RS232 serial
Connect the RS232 wires to a 9 pin D-SUB male connector that can be
plugged into a COM port of a PC (RS232): Gray (Ground) to pin 5, Green
(Transmit) to pin 2, and Yellow (Receive) to pin 3. See section 0.
Use the Demo and Configuration Software (see Section 9) to connect to
the sensor via the serial port and get distance measurements.
1.3.2.2
RS485 serial
Connect the RS485 wires to a RS485 adapter connected to a PC COM port
Gray (Ground) to pin 5, Green (Data+) to pin 2, and Yellow (Data -) to pin
3. See section 0.
Follow the same instructions for RS232 serial above.
1.3.3
Analog Output Signals
Quick suggestion: connect a DVM (digital volt meter) to the wires: Gray to
Common, Blue to mA input. Type QA. The output is a 4-20mA current loop
from 0 to the maximum range. The meter should read near 4 mA when a
target is placed in the laser beam near 0 mm and 20 mA near the end of
the range
