Does anyone know the pinouts for the 9 Pin Low Speed Data connector on the Sony A50 and B50 DSS Recievers? I need to access the diagnostic menu.

Thanks,
Mr. Wizard

Nevermind, I found it. For those of you who want to know. You can access the DSS's Diagnostic Program by connecting a straight through cable from the Low Speed Data port to a PC. Press enter and you will see a DiagPrompt> prompt. Type ? for a list of commands. Different models have different commands, the following is a list of commands from the a1-a4 and b1-b4 series, the A50 and B50 are slightly different. Here are all the commands you can use:

--------------------------------------------------------------------

DiagPrompt > ?

1 rom - Test ROM checksum
2 tram - Read/Write Test Transport IC SRAM
3 vram - Read/Write Test MPEG video DRAM
4 eprm - Read/Write Test EEPROM
5 ntsc - Show color bars
6 mpeg - Test MPEG video chip
7 tic - Test Transport IC
8 cam - Read access card
9 aud - Test audio IC
10 mdm - Test modem
11 led - Test front panel LEDs
12 butn - Test front panel buttons
13 rmt - Test remote control
14 exit - Exit diagnostics
15 ser - Set IRD serial number
16 ver - Set IRD model number
17 locks - Set Lock/Unlock/Skip/Unskip channels

19 dch - Set default channel
20 eep - Initialize EEPROM
21 dump - Dump data from memory
22 probe - Go to probe
23 sniff - Enable Sniffer Output
24 pis - Simulate PI
25 camid - Display CAM ID number
26 fend - Set the Front End type
27 lsdr - Read from the low speed data port
28 lsdw - Write to the low speed data port
29 lsdb - Set the low speed data port baud rate
30 rf - Set RF/IR remote state
31 sec - Set RF security code
32 hss - Write to the high speed data port
33 ? - Display list of commands

Syntax: [r rptCnt] {cmdName | cmdNum} [options] [- {cmdName | cmdNum}
[options]]
rptCnt = 0 means repeat forever (default = 1)
Numeric values default to decimal. Use 0x before numbers for hex values.

For help on specific commands, type command name followed by ?

Diag > OK

what have you been able to do with this?

Wayne,

There isn't a whole lot you can do with this. One thing is to type ntsc to display the color bars for adjusting your TV Set. I just wanted to see what it was all about.

"Dump Data From memory."

What data do you suppose is dumped?


Just curious.
