Specifications
4-4 Data Format and Input Range
Two’s Complement Hexadecimal
• Data format bit 1 and 0 set to 10 is 2’s complement.
• Data is 4-character(16 binary bits) hexadecimal string.
• Positive full scale is 7FFF (+32767)
• Negative full scale is 8000 (-32768)
Example 1 :
• Input Range is ±5 V
• Input is +1 Volts
Two’s complement hexadecimal : 1999<CR>
((1/5) x 32768) = 6553.6 = 1999H
Example 2 :
• Input Range is ±5 V
• Input is -2 Volts
Two’s complement hexadecimal : CD27<CR>
((-2/5) x 32768) = -13107.2 = CD27H
Example 3 :
• Input Range is ±10 V
• Input is +4 Volts
Two’s complement hexadecimal : 3333<CR>
((4/10) x 32768) = 13107.2 = 3333H
Example 4 :
• Input Range is Type K thermocouple (range 0°C to 1000°C)
• Input is 406.5°C
Two’s complement hexadecimal : 3408<CR>
((406.5/1000) x 32768 ) = 13320.2 = 3408H
