User’s Manual
Figure 2 Wiring configuration for 9-pin connector
for RS232 serial communications
RS422
: An RS422 adapter must be used to connect the AR2700 to a PC. See the wire
functionality chart in section 3 for details.
For testing use a terminal emulation program such as HyperTerminal or TeraTerm.
After naming the connection and choosing an icon, choose the COM port that the
AR2700 is connected to. In the next configuration screen, set to 112500 baud, 8 bits,
NO parity, 1 stop bit and NO flow control to communicate with a sensor in the default
configuration.

Power On
Connect a 15 volt (10
– 30 volts) power supply to the power and ground lines of the sensor
cable. See Signal and Power Interface (section 3) for wire connections. Only the power
and ground need be connected for operation in addition to the serial interface.
When power is applied the laser beam will be emitted from the bottom half of the sensor’s
window. The sensor will immediately begin measuring in
Distance Tracking
mode.
Distance readings will scroll down the terminal emulator and the default units are be in
meters. See section 4.1 for command information.
