2) Comms control
The remote control software controls all communications. Data send/receive (BSC
handshake) is by transferring TEXT data to the camera controller chip.
3) Comms procedure
The following pages indicate the camera controller chip and remote control software
data protocol. In the description, the camera is designated as slave and the software
as master.
Receive protect timer (time out error)
The receive protect timer for master and slave processes is 1 second. For example,
if 1 block of TEXT data is being received, if the data interval exceeds 1 second, error
is produced and the data are lost. An acknowledgment of data receipt is not
produced.
