Bit7
:
ins trument working mode
,
there are four mode:
Mode 1 (long data mode: set up as 00)
:
GID of every ins trument can receive info at this mode, and it can s pecifically
us e on data info that is larger than 127Bytes .
Mode 2 (ID: info mode 1
:
set up as 01)
:
Once GID can trans mit to particular S ID ins trument under this mode, it is
one to many; the s ingle info mus t
≦
127Bytes .
Trans mis s ion: The firs t Byte is the S ID of the receiver, and from the
s econd byte, it becomes data.
Example: The S ID of device A is 55, the S ID of device B is 88, and they have
the s ame GID. Under mode 2, device A is going to trans mit data
0x1234567890, 5 Bytes in total, to B device, A then s ends data
0x881234567890, 6Bytes in total to B, B will receive 0x551234567890, 6Byte
in total. The firs t Byte is the S ID of the trans mitter.
Mode 3 (ID: info mode 2
:
set up as 10)
:
Once GID can trans mit to particular S ID ins trument under this mode, it is
one to many; the s ingle info mus t
≦
127Bytes .
Trans mis s ion: Data s hall be trans mitted under the s ame rule of the thirteen to
thirty-two Byte.
Example: The GID of device A = AAAA, S ID = 55; the GID of device B = BBBB,
S ID = 88; the GID of device C = CCCC, S ID = 99.
A is going to trans mit 0x1234567890 to B, 5 Bytes in total. A then s ends
0x04FFBBBB881234567890, 10 Bytes in total, to B, B will receive
0x1234567890, 5 Bytes in total.
A is going to trans mit 0x1234567890, 5 Bytes in total, to B via C. A then s ends
0x08FFBBBB88FFCCCC991234567890, 14 Bytes in total, C will receive
0x1234567890, 5 Bytes in total, but B will not receive any data.
