RS-232C Command List

Communication

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.
