I tried sacd and the cd track of an sacd, and a dvd, all worked when pressing 1 on the denon remote, but not with the hex, I'll try the ASCII aswell.

I'm trying it with pronto script, but I'm not sure why I can't get it to work. I've tried //x aswell. The extender number and rs232 are correct and the rs232 light blinks.
SerialCode("40","00","00","00","00") returns x02x40x00x00x00x00x03x34x33 or \x02\x40\x00\x00\x00\x00\x03\x34\x33 when using \\x. Using \x02\x40\x00\x00\x00\x00\x03\x34\x33 direct works.


function SerialCode(varCommand, varParameter0, varParameter1, varParameter2, varParameter3)
{
var varStx = "02";
var varEtx = "03";
var varCalc = parseInt(varCommand, 16) + parseInt(varParameter0, 16) + parseInt(varParameter1, 16) + parseInt(varParameter2, 16) + parseInt(varParameter3, 16) + parseInt(varEtx, 16);
varCalc2 = varCalc.toString(16)
var varBatchHigh = varCalc2.substr(0,1);
var varBatchLow = varCalc2.substr(-1,1);
return "\\x" + varStx + "\\x" + varCommand + "\\x" + varParameter0 + "\\x" + varParameter1 + "\\x" + varParameter2 + "\\x" + varParameter3 + "\\x" + varEtx + "\\x" + varBatchHigh.charCodeAt().toString(16) + "\\x" + varBatchLow.charCodeAt().toString(16);
}
var extender1 = CF.extender[1];
if( extender1 == null )
{
Diagnostics.log("Extender 1 is not defined");
}
else
{
var rs232port2 = extender1.serial[1];
if( rs232port2 == null )
{
Diagnostics.log("Extender 1 is not a serial extender");
}
else
{
rs232port2.bitrate = 9600;
rs232port2.databits = 8;
rs232port2.parity = 2; // Even
rs232port2.stopbits = 1;
panel2.label = SerialCode("40","00","00","00","00")
rs232port2.send(panel2.label);
}
}

To build a set of hexadecimal binary characters using the string method as you've done above, you shoud eval() the results of the concatenation.

eval('\\x' + '41'); Results in a hex bytecode value of 65 which is the character code for 'A'.

Note that the end result of the string concatenation of my above expression (what's inside the eval parens) is '\x41', which when evaluated using eval() will build character code 'A'.

The quick and dirty fix is to change your return .... concats containing all the double backslashes to:

return eval(... string concatenation result);

Thanks for helping Lyndel, bu I can't get it to work. eval('\\x' + '41'); gives no result.

SerialCode("40","00","00","00","00") gives \x02\x40\x00\x00\x00\x00\x03\x34\x33
rs232port2.send("\x02\x40\x00\x00\x00\x00\x03\x34\x33") works, so why won't
rs232port2.send(SerialCode("40","00","00","00","00"))?

sWORDs:

Your SerialCode will return a String containing '\', 'x', '0', '2', ...

What you want is something that returns a String containing '\x02', '\x40', ...

A possible way to do this is like:

function SerialCode(command, parameter0, parameter1, parameter2, parameter3)
{
        var stx = 0x02;
        var etx = 0x03;
        var calc = command + parameter0 + parameter1 + parameter2 + 
                         parameter3 + etx;
        return String.fromCharCode( stx, command, parameter0, parameter1, 
                         parameter2, parameter3, etx, (calc >> 8)&0xff, calc & 0xff);
}

and use it like:

mycode = SerialCode(0x40, 0x00, 0x00, 0x00, 0x00);
rs232port2.send(mycode);

Note that you cannot set such a String containing arbitrary binary values as a label (you can, but the result will be garbage - the binary content will be interpreted as ASCII codes)

You could use something like:

function BinaryDump(s)
{
        var result = "";
        for (var i=0; i<s.length; i++) {
                result += "\x" + s.charCodeAt(i).toString(16);
        }
        return result;
}

mycode = SerialCode(0x40, 0, 0, 0, 0);
panel2.label = BinaryDump(mycode);
rs232port2.send(mycode);

Enjoy.

Sogliphy, I'll try it!

For the ones trying to parse a Denon DVD here's my debug code (not tidy yet, and two bugs, no track info with SACD, DSD always gives highest available channels instead of current selected, both are probably bugs in Denon's protocol):

I really don't get this part:
(calc >> 8)&0xff, calc & 0xff)

Could some on explain what it does? (Right shift with sign extension, Bitwise AND
???)

Playing with ProntoScript is really nice, I like the polling:

n/m

Very Nice

sWORDs,

The expression '(calc >> 8)&0xff' yields the value of bits 9-15 of the integer representation of the value assigned to 'calc'. Bits 9 through 32 are first shifted right, this yields the value of bits 9-32. Then a bitwise AND is performed with 255, or 0xff, which is '11111111' in binary. This ensures that the result is constrained to values 0 to 255 (not strictly necessary in your case, since calc will never be bigger than 1277 (= (5 * 0xff) + 0x02) there, but a good habit anyway).

Finally, 'calc & 0xff' yields the value of bits 0-7 of the integer representation of the value assigned to 'calc'.

Hello all,

I have managed to make most RS-232 commands for a Denon DVD 2930 work but I can't find some commands (not even from the Denon site).
Are there RS-232 codes for the following commands:
Digits (0-9), +10, repeat, random, clear, zoom, pic-adjust & search mode.

Thanks in advance for any help.

I've never seen codes for digits but I've got these:
Random: 02 6B 00 00 00 00 03 36 3E
Clear: 02 66 00 00 00 00 03 36 39
Zoom: 02 6D 00 00 00 00 03 37 30
Picture Adjust: 02 6F 00 00 00 00 03 37 32

Good luck with the others, and let me know if you find anything.
