6.2 Setu
Block data is sent from the host to the QT in a block of hex data. The block can only be loaded in Setups mode following two sequential 0x01 commands.
Refer also to Section 6.5, page 19 for further details, and all of Section 5.
CRC Note: A CRC calculator for Windows is available free of charge from Quantum Research on request.

Description
Lower nibble = Neg Threshold - take operand and add 4 to get value
Upper nibble = Pos Threshold - take operand and add 4 to get value
Lower nibble = Neg Drift comp - Via LUT
Upper nibble = Pos Drift comp - Via LUT
Lower nibble = Normal DI Limit, values same as operand (0 = disabled burst)
Upper nibble = Fast DI Limit, values same as operand (0 does not work)
Range is in 0.5 sec increments; 0 = infinite; default = 10s (operand = 20)
Range is 0.5...127s
Lower nibble = PRD, via LUT, default = 6 (1 sec)
Bits 5, 4: = BL, via LUT, default = 48 (setting =2)
Bit 6 = AKS, 1 - enabled
Bit 7 = Scope sync, 1 = enabled
Lower nibble = Neg hysteresis, all keys; default = 12.5%
Bits 5, 4 = Dwell time, 3 values via LUT, default = 187.5ns
Bits 6 = Mains sync, pos edge sensitive, 1 = enabled; default = 0 (off)
Lower nibble = burst spacing; default = 0 (automatic)
Upper nibble = serial rate via LUT - 9600, 19.2K, 38.4K, 57.6K, 115.2K (UART)
Lower limit of acceptable signal; below this value, declares error
Controls what the LED does; see table, below.
