9.3 Transmitting Junction PROTOCOL
[P1] + [P2] + [DEST] + [0:00:LEN] + [DATA-0] + … + [DATA-n] + [ECC]
- It is used for transmitting data from the Host system (PC/MODEM) to GIMAC/GIPAM
or vise versa. And FN in the data frame for transmission is 00 at this point.
- E bit in the data frame for transmitting or receiving is always 0.
-The data frame that GMPC has received is discarded when there is ECC error on it .
-The data frame that GMPC has received is also discarded when there is an error in
value on it.
-The structure of the data frame Ex.) 0xFF + 0x00 + 0x23 + [0:00:1] + 0x10 + 0x34
9.4 Synchronization PROTOCOL
[P1] + [P2] + [DEST] + [E:01:LEN] + [DATA-0] + … + [DATA-n] + [ECC]
It is used for synchronizing GMPC with the Host system(PC/MODEM). And FN in the
data frame for transmission is 01 at this point.
The data in [DEST] is disregarded.
