8.1 S-LINK-2 BINARY MODE DESCRIPTION
8.1.1 DESCRIPTION
The S-LINK-2 has two Communication Modes: the Binary Mode for FAST data acquire and the ASCII
mode for slow and high resolution values. The resolution of the Wattmeter Mode is 11- bit, the resolution
of the Joulemeter Mode is 12-bit. The resolution in ASCII mode is 15 bits.
The value in binary mode is coded in two bytes
JOULEMETER MODE
Byte #1
C
O 2 X X X X X
Byte #2
C
O X X X X X X
2 = The MSB of the 12 bit codification for the Joulemeter Mode.
X = Bits of the Codification.
WATTMETER MODE
Byte #1
C
O 2 Y X X X X
Byte #2
C
O X X X X X X
2 = The sign.
Y = The MSB for the Wattmeter Mode.
X = Bits of the Codification.
FOR ALL MODES
C = Channel number
0 = Channel #1
1 = Channel #2
O = Order
1 = First byte
0 = Second Byte
