is way ahead of me
If you
havent got VB
Then
try
Com7

this
alows
you to see what is happening between the PC and the

DSP-AX1
Please bear in mind that this is my interpretation of what they are
saying..and that this
is all theoretical for me - I don't have a unit to test... unless....
;-)
I may be able to knock together some VB code for you to do some of
this..
but not this weekend
as it's the wife's birthday!!!
1. Connect up the Rx and your pc with proper cable.
2. Within a program (VB should work) open the COM port 9600, 8N1 and
with
HARDWARE hanshaking turned on.
3. To get a response from the unit send the following:
ASCII char 17
ASCII Char 17 is DC1
ASCII char 0
ASCII char 0
ASCII char 0
The 3 ASCII char 0 's are the timeout
values, by sending 0's we
set NO TIMEOUT.
ASCII char 3
ASCII char 3 is ETX
This should send some data back ( the current configuration of the
system)
To read the current config:
a. The first character will (should) be a DC2 (ASCII char 18)
b. Then the model number of the unit responding 5 bytes (characters)
long.
c. Then the length of the data to follow 2 bytes (characters)
long.
The data will then follow (not clear if it ALWAYS will be 256 bytes
long
or as long as
the length secified above in c. The values of the data will be as per
the
table on page 2.
eg DT0 (or the first byte) will contain either a zero or a one. Zero
meaning OK and 1 meaning BUSY
The checksum is follows and an ETX (ascii Char 3) terminates the output
from the RX
The above part is the initial communications that MUST take place first
of all. Then when you
want to issue a command:
0 = Command that would be on remote control
1 = Command (???)
2 = System Command
For example to turn the volume up:
Send STX (ASCII CHAR 2)
Send 0 (ASCII char 0)
Send 7
Send 10 (ascii char 10)
Send 1
Send 10 (ascii char 10)
Finally send ETX (ASCII CHAR 3)
The volume should turn up!

The best way to save face is to keep the lower part shut.
