(5) Command “A”
Function: Command for setting analog image signal
Transmission from host: STX: “A”: (SETUP setting value): (WC setting value): “.”: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
2 digit ASCII codes in the hexadecimal system are used for the data setting values of SETUP and WC.
Example) If level 128 (decimal) is set:
“80”
If level 200 (decimal) is set:
“C8”
The setting value that does not require a change should be represented by “.” (a full stop) so that the setting value before
the command transmission is retained.
(6) Command “E”
Function: Command for editing shutter menu
Transmission from host: STX: “E”: “H”: SW0: SW1: SW2: SW3: SW4: SW5: SW6: SW7: SW8: SW9: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
* The exposure time (H) to be allocated to the shutter SW number is expressed in 4 digits in the hexadecimal system for
SW0 to SW9.
* The exposure time of SW0 cannot be changed.
Example) If only the exposure time of SW5 for the high speed shutter operation is changed to 88 (decimal):
STX: “E”: “H”: “.”: “.”: “.”: “.”: “.”
: “0058”: “.”: “.”: “.”: “.”: ETX
(7) Command “W”
Function: Command for saving operation mode (Write into page memory)
Transmission from host: STX: “W”: memory page (“A” to “F”): ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
The current setting is written and saved in the EEPROM of the specified page number. Registered data are retained even
at power-off unless they are overwritten or initialized.
(8) Command “L”
Function: Command for reading out operation mode (Load)
Transmission from host: STX: “L”: reading page (“A” to “H”): ETX
Return by camera :
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
* The factory default is stored in the Page H, which will be used when resetting to the default setting.
[Important]
(Note) Sometimes, indefinite signal (data packet) is output through serial interface of camera when turning on/off the
camera, while connecting to the running host computer. Be sure to include the steps of clearing the receive buffer
of host computer in advance or neglecting more than one byte of receiving data after having sent a dummy
command to the camera, when the host computer receives the data packet from the camera which was activated
after the activation of the host computer.
Also, it is recommended to implement the above procedure at the initializing stage of the software for the
unexpected power-on sequence(e.g. the camera is activated after host computer)
