<------ :,AA,03H,08,D1,D2,D3,D4,D5,D6,D7,D8,LRC,CR,LF
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 = not 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
