7 Computer control

Connect the AR-ONE (any of the 2 serial sockets) to your computer’s serial port, using a

RS-232C cable terminated in a 9-pin plug.

The RS-232C parameters may be defined using the CONFIGURATION menu. Baud rates

(data transfer speed) may be set to 9600, 19200 or 38400 bps. 19200 bps is the factory

default. It is also possible to set an ‘address’ to facilitate connection of up to 99 AR-ONE

receivers to a single port for custom operation, the addresses may be set between the limits

of 01 to 99 with 00 representing single radio operation.

7-1 How to send an RS-232C command

Each command comprises of two upper case letters (header) along with operations as

required. All commands use ASCII code which MUST BE IN UPPER CASE (except for the

up arrow key, down arrow key, right arrow key, left arrow key and remote ID command (^A)

which are non-printable and use the control codes of ASCII). A terminal program such as

Windows Hyperterminal should be set as follows:

Baud rate 9600, 19200 or 38400 bps (this must match AR-ONE)

DATA BIT 8

STOP BIT 2

PARITY NONE

XFLOW NONE

Make sure that “local echo” is turned on. On Windows Hyperterminal you can access this

setting at: FILE > PROPERTIES > SETTINGS > ASCII SETUP. Check the box labeled

“Echo typed characters locally” and validate with OK.

7-2 Power on the AR-ONE

There are 2 switches to set ON:

-On the back of the receiver, labeled “MAIN”. The switch’s green LED should light.

-On the front panel’s “PWR/VOL” knob. Turn it slightly clockwise until you feel a click. The

receiver’s LCD and keys will light after about 4 seconds.

Now you can send any command from your PC’s Hyperterminal software.

All commands MUST BE IN UPPER CASE.

A multiple command entry is only valid where specified. Where a multiple command entry is

allowed, each command MUST be separated with a space “h20” (HEX DECIMAL). Each

command is completed and a [CR] or [CR][LF]. Although there is no local echo, either [CR]
