Specifications
This unit utilizes an RS-232C-compliant, flow
controlled, synchronous serial interface.
Because the RS-232C setting is set to OFF when the
unit is shipped from the factory, you must change the
setting of the internal DIP switches to utilizes the RS-
232C function. (Before changing the settings make
absolutely sure that the power to the unit is turned off.
(See “Setting the RS-232C Switches” (page 11).))
The parameters are as follows.
Communication speed : 9600 bps
Data length
: 8 bit
Stop bit
: 1 bit
Parity
: None
This is a no-flow-control, no-handshake protocol, each
bite is transmitted from the LSB line.
Characters that can be transmitted are ASCII codes
30h to 39h, 41h to 5Ah (Alphabetic capital letters A to
Z, Arabic numerals 0 to 9), a space (20h), and a
Carriage Return (0Dh).
Thus the commands used to control the camera are
made up of the character set specified above, and each
command must end with a Carriage Return character
(0Dh).
Because this is a no-flow-control protocol, to prevent
communication overflows, if the host side sends one
byte, before sending the next byte, insert a 1 ms stop
period.
