where:
-AA
= 01 = address of the MICROVIP3 PLUS selected(2 bytes ascii)
-03H(04H)
= Code of the command for reading of N words(2 bytes ascii)
-002E
= address from which the reading starts (4 bytes ascii)
-0004
= Number of words to be read (4 bytes ascii)
-LRC
= Longitudinal Redundancy Check (2 bytes ascii)
-CR
= 0DH (1 byte ascii)
-LF
= 0AH (1 byte ascii)
-08
= Number of bytes read
-D1
= not used
-D2
= PT primary in volts(in BCD, last 2 digits)
-D3
= PT primary in volts(in BCD middle 2 digits)
-D4
= PT primary in volts(in BCD first 2 digits)
-D5 =

used
-D6
= not used
-D7
= not used
-D8
= PT secondary (in binary)
-0XH = 57,7 Volts
-1XH = 63,5 Volts
-2XH = 100 Volts
-3XH = 110 Volts
-4XH = 115 Volts
-5XH = 120 Volts
-6XH = 173 Volts
-7XH = 190 Volts
-8XH = 200 Volts
-9XH = 220 Volts
Note:
X means don’t care in order to read only the high nibble of datum D8 .
E.g. :
-PT primary
= 200400 Volts
-PT secondary = 100 Volts
-PT K
= 200400/100 = 2004
