Communications Protocol
[2] Communications Flow
Note: ◦Start the transmission of the next data after confirming the response command.
◦The maximum transmission interval of the various byte data is 500 [msec]. If this is exceeded, a communication error is detected in the camera unit, the receiving data is deleted, and data from the header is waiting to be received again. Furthermore, there are no special regulations regarding the minimum value.
◦All the commands can be acquired after the periods below after
MD600(P), MD500(P): 6 seconds
MD800(P), MD700(P): 9 seconds
When auto pixel defect compensation is set to ON, below period will be added to above at the longest.
MD600(P), MD500(P): 15seconds
MD800(P), MD700(P): 20seconds
