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
