KP-FD30 remote control protocol (Rev.1)

1) Comms* specifications

Sync system Start-stop sync

Bit rate 9600 bps

Data length 8 bits

Start bit 1

Stop bits 1

Parity None

Bit transfer LSB first

*Comms : Communications

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.
