・Control system
・Transmission rate
・Data length
・Star bit
・Stop bit
・Parity
・Bit transfer
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 describe the data protocol between the camera control micro-chip and remote control software.
The camera control micro-chip 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.
• Receive protection timer (time-out error)
Master, as a common process for the slave, and the received protection timer with one second.
When receiving and controlling one block data like "TEXT" etc., if the data interval has elapsed for more than 1 second,
Immediately discard the received data as an error.
Also, response signal for the received data is not output.
