showing either no status indications or one or both of the DCD

indicators. If the Status display lights and other status

indicators are displayed, then the PK-900 has already been

initialized. If you know the terminal baud rate the PK-900 has

been set to, you may proceed to step 11; otherwise you must

reset the PK-900 as described below.

To reset the PK-900, simply hold the rear-panel RESET switch in

at the same time you turn on the power switch. After this is

done, then the only LCD Status indicators showing may be the DCD

indicators. If your serial port is operating at 1200 bauds as we

recommend, you'll see the "autobaud" message:

Please type a star ( * ) for autobaud routine.

If your serial port is operating at 300, 2400, 4800 or 9600

bauds, you may see some "garbage" characters.

This is normal and you should proceed with step 7.

7. Type an asterisk (*). When the PK-900 has "recognized" your

computer's data rate, the CMD LCD will light. Your screen will

then display the sign-on message:

PK-900 is using default values.

cmd:

Make note of the Release date on the first page of this manual.

This is important should you ever call AEA for technical support.

It should match the firmware release sticker on the bottom of

your PK-900.

8. If you are using an AEA program, follow the instructions in the

program manual to enter the packet callsign (MYCALL) of AAA into

the PK-900. Even though this is not your callsign, please do

this for this procedure. You must change it to YOUR OWN CALLSIGN

after completing this procedure.

If you are using a Computer Terminal or a non-AEA terminal

program the following will set your packet callsign to AAA:

Enter MYCALL by typing MY AAA <Enter> (or <RETURN>).

(<RETURN> or <Enter> means type the single key on your keyboard.)

Your monitor should display:

MYcall was PK900/PK900

MYcall now AAA/PK900

9. If you are using an AEA program follow the instructions to

CONNECT in packet mode to AAA. Since you have just entered your

callsign as AAA, you will connect to yourself.

If you are using a Computer Terminal or a non-AEA program,
