function asciiToHex(asciiValue){
    var arr1 = [];
    for (var n = 0, l = asciiValue.length; n < l; n ++) {

C# Algorithm Converts Hexadecimal numbers to ASCII code

public static string HexadecimalToASCII(string hex)
{
	string ascii = string.Empty;
	for (int i = 0; i < hex.Length; i += 2)
	{
		ascii += (char)HexadecimalToDecimal(hex.Substring(i, 2));
	}
	return ascii;
}

private static int HexadecimalToDecimal(string hex)
{
	hex = hex.ToUpper();
	int hexLength = hex.Length;
	double dec = 0;
	
	for (int i = 0; i < hexLength; ++i)
	{
		byte b = (byte)hex[i];

		if (b >= 48 && b <= 57)
			b -= 48;
		else if (b >= 65 && b <= 70)
			b -= 55;

		dec += b * Math.Pow(16, ((hexLength - i) - 1));
	}

	return (int)dec;
}
