Datavideo SE-500

zerodev

Does anyone have experience controlling one of these devices? I just looked up the protocol and it's a bit convoluted and unclear. I was hoping someone would have the basics coded (e.g. "Select Input 1") so that I wouldn't have to spend a few hours decoding the control protocol and then playing trial-and-error with the code.

Thanks!

Hi

Do you have the control protocol? I am having problem figuring out with the checksum

Post the protocol.

If it's the same as the DN-500, this should work.

define_function char CheckSum(char _cCommand[])
{
	stack_var		integer		_nCharacterIndex
	stack_var		integer		_nBitIndex
	stack_var		char			_cCheckSum
	
	for(_nCharacterIndex = 1; _nCharacterIndex <= length_array(_cCommand); _nCharacterIndex++)
	{
		for(_nBitIndex = 0; _nBitIndex < 8; _nBitIndex++)
		{
			if(_cCommand[_nCharacterIndex] & (1 << _nBitIndex))
				_cCheckSum++
		}
	}
	return _cCheckSum
}
