The function enables you to select the reference signal of the receiver.

The AR-ONE has built-in a stable reference oscillator, however, an external high stability 10

MHz reference (such as off-air atomic coupled) can be accepted from the SMA connector

(marked as 10 MHz IN) on the rear panel of the AR-ONE.

Push the down arrow key to move the cursor to "REF SEL" selection point.

Use the main tuning dial or the right arrow key or the left arrow key to select the desired

reference signal source (internal or external). The default is INT.

Push the ENT key to accept data and return to a standard display.

Alternatively, push the ESC key to abort entry.

This completes the configuration settings.

Computer control

Connect the AR-ONE to one of the serial port of a computer using an RS-232C cable

terminated in a 9-pin plug.

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

(data transfer speed) may be set to 4800 or 9600 bps. It is also possible to set an 'address'

to facilitate connection of up to 99 AR-ONE 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.

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

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

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 running

a computer should be set to:

Baud rate:

DATA BIT:

STOP BIT:

4800 or 9600 bps (this should match the AR-ONE)
