ADLINK ND-6018 - Manual (Page 96)

88 • Data Format and Input Range
• Data is sign (+ or - ) followed with 5-digits and a decimal point
• It does not exceed 7-characters
• Maximum resolution is 0.01%, the decimal point is fixed
• Data is the ratio of input signal to the value of full scale range
Example 1:
• Input Range is ±5 V
• Input is +1 Volts
% of FSR: +020.00<CR>
(+(20/100) x 5 V) = +1 V
Example 2:
• Input Range is ±10 V
• Input is +4 Volts
% of FSR: +040.00<CR>
(+(40/100) x 10 V) = +4 V
Example 3:
• Input Range is Type K thermocouple (range 0 °C to 1000°C)
• Input is 406.5 °C
% of FSR: +040.65<CR>
(+(40.65/100) x 1000
°C ) = 406.5°C
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
