[UP] [DOWN] similar to the receivers keyboard.

Typical format of commands:

AT Attenuator ON/OFF.

AT0 = Attenuator Off

AT1 = Attenuator On

SR1 will return the Search Mode Data in Search Bank 1 as follows:

SR1 SL0076000000 SU0107750000 AU0 MD0 ST050000 AT0

This can be broken down as:

SR1 = Search Bank 1

SL0076000000 = Lower Search Limit (76.0MHz)

SU0107750000 = Upper Search Limit (107.75MHz)

AU0 = Automode if Off

MD0 = Mode is WFM

ST050000 = Step size is 500kHz

AT0 = Attenuator is Off

Multiple commands in conjunction with other commands are possible with a space in between:

AT, AU, MD, RF, ST,

Connections required for the

AR2700, COM600/COM610,

HSC-190/HSC-200 & TR-2000/TR-2200

Connecting any of the above, all of which are the same receiver (the

COM610/HSC-200/TR-2200 has slightly wider coverage with additional modes &

step sizes) to a PC with the JAV-232 requires the Flat Flexible Cable (FFC).

Plug the DB-9 into your Computers RS-232 Serial Port. You will need to configure

the software you are using with the correct COM Port (i.e. COM1, COM2, COM3

etc.) to correspond with the one you have used.

Remove the battery cover from your receiver to gain access to the Computer

Connection socket which is rather awkwardly located in the battery compartment.

Plug one end of the white FFC with the blue backing face uppermost into the

socket. You should feel this locate properly into the socket. If your unit does not

have a FFC type connector you need a suitable adapter (only early AR2700’s do

not have the FFC connector).

Place the other end of the FFC cable into the socket at the bottom of the front face

on the JAV-232, again with the blue backing uppermost.

You should now have two way communication between the receiver and your

computer. Using any terminal program (a Microsoft Windows™ ar8000.trm file is

supplied on the PC Manager for Windows disk) you can quickly check all is OK.

Using the ar8000.trm settings the only item you may need to change is the COM

port the JAV-232 is connected to on your computer. Make sure your receiver is

turned on.

Typing RF (in capitals) will return the current frequency stored in the VFO. The

return data will be something along the lines of:

RF0131050000 AU1 MD2 ST025000 AT0

This can be broken down as follows:

RF Manual VFO

0131050000 Set Frequency 131.05MHz

AU1 Auto Mode is set to On (AU0 would be Auto Mode is Off)

MD2 Mode set is AM (0=WFM, 1=NFM, 2=AM)

ST025000 Step Size set to 25.0kHz

AT0 Attenuator is turned Off (AT1 would be Attenuator is On)
