Specification : TS-S03D114E
March, 2005
Calibration constants for External Calibration Option, 2 wire address A2h
11. Calibration Calculation (SCP6EG4-GL-#N-xx)
Transceiver temperature: Temperature, T, is given by
T = T
SLOPE * TAD + TOFFSET
Where T
AD is 16-bit signed 2's complement A/D value at bytes 96-97, TSLOPE is unsigned
fixed-point value at bytes 84-85 and T
OFFSET is signed 2's complement value with LSB equal
to 1/256 deg-C at bytes 86-87. The result, T, is 16-bit signed 2's complement value with
LSB equal to 1/256 deg-C.The monitored output is the junction temperature of the diode inside the transceiver,
hence, there is some discrepancy between the output and transceiver case temperature of the point illustrated in
section 3 mechanical dimension.
Supply voltage: Voltage, V, is given by
V = V
SLOPE * VAD + VOFFSET
Where V
AD is 16-bit unsigned A/D value at bytes 98-99, VSLOPE is unsigned fixed-point
value at bytes 88-89 and V
OFFSET is signed 2's complement value with LSB equal to 100 V at
bytes 90-91. The result, V, is 16-bit unsigned value with LSB equal to 100 V.
