5. READING SCALE:
Multiplication factor applied to input to get a higher or lower reading.
This is 3 byte data (6 characters) as follows:
- Bits 0 to 18 (19 bits) are value of the scale from 0 to 500000
- Bit 19 is sign, 0 for positive and 1 for negative
- Bits 20 to 23 are for decimal point value = DP
It means as:
Actual decimal value = 10 ** ( 1 - DP )
where ** means "TO THE POWER OF"
example: if scale is -0.000345678.= - 345678 x 10**(-9)
value will be 345678 decimal = 5464E hex
bit 19 =1 for negative
bits 20-23 = DP = 10 = Ahex
then data will be AD464E hex
6. READING OFFSET
:
Deviation applied to input to get a higher or lower reading.
This is 3 byte data (6 characters) as follows:
- Bits 0 to 19 are value from 0 to 1000000
- Bit 23 is sign, 0 for positive, 1 for negative
- Bits 20,21,22 are decimal point value = DP
It means as :
Actual decimal value = 10 ** ( 2 - DP )
where ** means "TO THE POWER OF"
example: offset value is 234.089
value of 234089 decimal = 39269 hex
decimal value = 10 ** (-3) then DP=5
then 234.089 decimal = 539269 hex
7. COMMUNICA
TION PARAMETERS:
This is one byte data and specifies

BAUD = bits 2,1,0 are:
000-001 not used
010 for 1200
011 for 2400
100 for 4800
101 for 9600
110 for 19200
111 not used
