Here is a function you can use to convert 8-bit (2 char) hex values to SQL TINYINT

CREATE FUNCTION dbo.HexToTINYINT 
(
	@Value VARCHAR(2)
)
RETURNS TINYINT
AS
BEGIN
	DECLARE	@v TINYINT

	SELECT	@Value =  RIGHT(UPPER('00' + @Value), 2)

	IF PATINDEX('%[^0-9A-F]%', @Value) < 1
		SELECT @v =	(CHARINDEX(SUBSTRING(@Value, 2, 1), '0123456789ABCDEF', 1) - 1) +
				16 * (CHARINDEX(SUBSTRING(@Value, 1, 1), '0123456789ABCDEF', 1) - 1)

	RETURN @v
END

You can also convert the data into varchar or varbinary.
