Has anyone controlled the Tascam DV-D01U DVD player Via RS232?
I can't get it to do anything.
cheers

Yup. 9600,8,N,1

My guess is the checksum is giving you problems. Did you try copying the Play command right out of the manual? You have to send the spaces too.

jakothechicken, can you post if you're successful with the DV-D01U? I'm trying to control a TASCAM SS-R1 solid state recorder with an MSC-400 and I can't get any reaction from the machine. TASCAM has a pretty thorough description of the RS232 protocol, but so far I've had no luck. Thanks

What did you do to fix it?

Uh oh!! I want answers too! I just made program for Crestron control system, used some IR codes for different Tascam CD player. I would much rather use RS232.
Can someone please post example of correct RS232 commands?

So how did it go?
I just used IR, works like a charm.... ;)

Play: \x02\x3E\x50\x4C\x59\x63\x46\x57\x44\x20\x20\x20\x20\x20\x31\x37\x03

Stop: \x02\x3E\x53\x54\x50\x63\x20\x20\x20\x20\x20\x20\x20\x20\x39\x38\x03

Pause: \x02\x3E\x50\x4C\x59\x63\x50\x41\x55\x20\x20\x20\x20\x20\x31\x43\x03

The 2nd and 3rd bytes from the right are the ASCII equivalent of a binary checksum. You sum everything >after< the STX byte, take the lower 8bits of the result, then convert the resulting hex value to its ASCII equivalent.

Example: \xFF + \x02 + \x03 = \x104 -> \x04 (lower 8 bits) -> \x30\x34 (converted to ASCII '04')

Better late than never?

Play \x02>PLYcFWD 17\x0D
Stop \x02>STPc 98\x0D
Pause \x02>PLYcPAU 1C\x0D

There are a few commands. Maybe you were not doing the Checksum? It is important to keep the spaces in there as well. Overall it is pretty simple. Hell, my module which has feedback consists of a single SIO.



***Edit, Holy cow, I reply a few days later and I am beat by 45 mins! And by a much better response***

Sorry for being so late to the party. I am able to control the Tascam DV-D01U DVD player but I cannot get any response back from the unit. Has anyone had success doing that?

Lo all,

Just thought I'd do my bit and share what I've learnt.

First thing - your cable. You really need to make your own.With the DV-D01U pin 2 is receive data, pin 1 is transmit data. However, what you need to be careful of is where your ground is.

The DV-D01U expects ground on pin 5. I was using a cable I thought would work until I decided to cut it up and discovered that my ground wasn't on pin 5, it was on the outside shield of the connector. I'm using an AMX unit for control, so it was easy enough just to chop the end of the cable off and use a continuity test on a multimeter to make sure the right pins were going to the right places on the AMX's phoenix connector.

Second thing. The manual dictates the 'Play' command like this;

02h 3Eh 50h 4Ch 59h 63h 46h 57h 44h 20h 20h 20h 20h 20h 31h 37h 03h

No idea why all those lower case h's are in there. I successfully managed to get the machine to play with the following code;

02 3E 50 4C 59 63 46 57 44 20 20 20 20 20 31 37 03

Thanks for the info above, I don't think I would have worked out what's going on with the RS232 command format without it.

Cheers guys
