6.16 Setups Block
Setups data is sent from the host to the QT using the I
reading/writing the appropriate address. Setups can be accessed individually or as a block. Before writing to any setup, an unlock code (value 0x55) must be written to the
setups write unlock address (130). Refer also to Table 6.2, page 22 for further details, and all of Section 6.

Lower nibble = Neg Threshold - take operand and add 4 to get value
Upper nibble = Neg Drift comp - via Lookup Table (LUT) (Table 6.2, page 22)
Upper nibble = Pos Drift comp - via LUT (Table 6.2, page 22)
Lower nibble = Normal DI Limit, values same as operand (0 = disabled burst)
For QT60160, only the first 16 locations are set to 2, the last eight are set to 0
Upper nibble = Fast DI Limit, values same as operand (0 does not work)
Range is in 0.5 sec increments; 0 = infinite, default = 10s
Range is {infinite, 0.5...127s}; 255 is illegal to use
Bit 3 = WAKE, 1 - enabled
Bits 5, 4 = BL, via LUT (Table 6.2 page 22), default = 48
Bit 6 = AKS, 1 - enabled
Bit 7 = Scope sync, 1 = enabled
Bits 2,1,0 = Sleep Duration, 8 values via LUT, default = 125ms
Bits 6 = Mains sync, negative edge, 1 = enabled, default = off
Range is in 100ms increments; 1 = 100ms. Default = 2.5s. 0 is illegal to use
Range is in 100ms increments; 0 = disable, 1 = 100ms, default = 1s
