Sony DSR-1500A

[Deleted User]

Is there anyone out there that can ease my misery with this device.

I am trying to control this from an accent 3pro on one of the builtin ports

so far I am hitting walls.
Pin out I am using is as follows
AMX-VCR
1-2
2-None
3-6
4-7
5-1(shield)
6-3
7-none
8-none
9-8

Does this look right?

Next baud is believed to be 38400 odd ,8,1 any one confirm that this looks correct for a sony prodeck?
(*following are defined as constant*)
Finally I am using these comands
sonyPL = "$20,$01,$21" (*play*)
SonyPA = "$20,$00,$20"(*pause*)
SonyST = "$20,$04,$24"(*stop*)
SonyFF = "$20,$10,$30" (*ffwd*)
SonyREW = "$20,$20,$40" (* rew*)
SonyFFX2 = "$21,$12,74,$7D" (* about 2x speed search fwd*)
SonyRWX2 = "$21,$22,74,$8D" (* about 2x speed search back*)
SonyREC = "$20,$02,$22" (* record *)
(*the first two characters coencide with what I see for earlier decks but I dont know what the third relates to... this was sent to me by a collegue either way with or without the final char it doesnt work)

on push
I am sending this
send_string dvSWC3,"(SonyPA)"

Can anyone see where I am going wrong?...losing sleep over Sony!

Try your cable like this:

AMX - Sony

1 - 2
4 - 3
5 - 4&6
6 - 7
9 - 8

This is assuming this is a Sony RS422 "standard" deck control port.

Sending a command should look more like this:

SEND_STRING dvSWC3,SonyPA

You don't need the quotes, and I believe the parenthesis might cause problems as well. You're likely to not be sending the string you think you are - I'm guessing the compiler sees the parenthesis and tries to evaluate whatever is between them mathmatically - at best, I think you're doing the equivalent of SEND_STRING dvSWC3,"1". (Which won't get you much response at all, even with the right cable)

Thanks for that chip I will get the soldering iron out tomorrow! change the code and see if this does the trick does the hex look right .. the more I delve into this the more conflicting answers to actual protocol I get..I have the deck tec manual coming and will post a pdf when I receive could you tell me if there is a way to see what the amx frame port is sending? through terminal or something>

Chip tried that cable
no joy

tried to send

PUSH[dvTP,64]
{
send_string dvSWC3,"$20,$01,$21"
}
no joy
any thoughts?

OK solve by making a sys_call to vcr8F

using cabling
AXCENT3

Glad you got it working...

With the cable you have (sorry about the bad wiring info - not sure how that happened) you should also be able to send the strings the way you tried prior to using the system call...

I can send the play command but no other.. in truth from the charts I cant see what the relevance is of the final part of the hex

the first two correlate

$20,$21 but the final i dont see anywhere any suggestions?

Sony RS422

The last byte you must send is the checksum byte. It's very easy to calculate. For example the player command $20,$01 has the cheksum $21 ($20+$01). So the checksum is calculated as the value of all the bytes without the checksum itself. See the attached file for the sony rs422 protcoll. Good Luck

DSR Status Command?

I don't see the status command to determine the current state of the device? Anyone?
