Timewave DSP-232, Operating Manual

Page: 23 / 271

Chapter 2 Power Supply and Computer Installation
The DSP-232 recognizes the letter
D
to mean “disconnect from...”
Your monitor should respond with:
cmd:***DISCONNECTED: AAA
AAA*>AAA
(
UA
)
Now you need to to the Loop-back test for 9600 bps on Radio Port 2. You need to take your wire Loop-back jumper
and plug one end into the 7 hole (9600 RX) and the other end into the 6 hole (9600 TX) of Radio Port 2. For those
using the cable method (described previously), unplug the cable and take a paper clip, straighten it out, bend it in
half, and insert it into RADIO PORT 2 as described above.
12. Set the 9600 TX AFSK LEVEL pot on the rear of the DSP to 50% rotation (straight up and down) using a
small screwdriver.
13. Press
(CTRL - C)
. When the cmd: displays on your monitor, type:
RESET
.
The seven segment LCD symbols ‘AU’ will light. (If the above doesn’t happen,
then refer to Chapter 13 - Troubleshooting .
If your serial port is operating at 1200 baud (this is the terminal baud rate), 7-bit even parity as recommended, you’ll
see the following message:
Please type a star
(
*
)
for autobaud routine.
If your serial port is operating at 2400, 4800, 9600, or 19,200 baud (this is terminal baud), you may see some
“garbage” characters. This is normal and you should proceed with Step 10.
14. Type an asterisk ( * ). When the DSP has recognized your computer’s data rate, its ‘AU’ lights will glow as
in the picture above. Your screen will then display the following sign-on message:

cmd:
At this point the DSP-232 is in its default mode: Radio Port 1, 1200 bps VHF Packet.
15. Enter the following text after the
cmd:
prompt to switch to Radio Port 2
RAD 2
16. At the command prmopt type:
MODEM 16
This is an alternate means of selecting a modem. We use HBAUD in previous examples, and you could at
this point too. But, in an effort to get you familiar with the DSP-232’s commands, we had you use the
MODEM command.
(After you are done with this entire Loop-back test type DIRECT at the cmd: to see
the whole list of modems available for the DSP-232.)
17. Now to make the Loop-back test work, at the cmd:, type:
HBAUD 9600
