(12) Command “RMF”
Function: Command for reading mode flag register (FR) (Read Mode Flag)
Transmission from host: STX: “RMF”: ETX
Return by camera:
STX: ACK: “RMF”: flag setting value: ETX (transaction completion), or STX: NAK: ETX
(transaction rejection)
The current content of the mode flag register (2 bytes/4 characters) is returned in the hexadecimal system.
(13) Command “SMC”
Function: Command for saving configuration flag register (CR) (Save Mode Configuration)
Transmission from host: STX: “SMC”: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
The current content of the common mode flag register is saved in EEPROM.
(14) Command “RTMP”
Function: Command for reading data of internal temperature of camera (Read TeMPerature)
Transmission from host: STX: “RTMP”: ETX
Return by camera:
STX: ACK: “RTMP”: internal temperature data: ETX (transaction completion), or STX: NAK: ETX
(transaction rejection)
The current content of the internal temperature data of the camera is returned in the hexadecimal system.
The effective data is the low 10 bits out of the returned 16 bits. This 10 bit value presents a signed integer value in two’s
complement form -511 to 511. Actual temperature in Celsius is calculated by multiplying the value by a certain factor.

Refer to “(4-6) Monitoring function for internal temperature of camera” for the conversion method from the returned
data to temperature value.
(15) Command “X”
Function: Command for asynchronous shutter trigger (eXecute trigger)
Transmission from host: STX: “X”: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
When the camera is set to be in the asynchronous shutter mode (excluding the time when the menu is being displayed),
this command enables the camera to update the image by internally generating the asynchronous trigger signal.
The internally generated trigger signal is of negative logic at 100ms±5%. The minimum repetition pitch is approx. 300ms.
Only when the trigger signal is input by this command, the internal buzzer of the camera sounds for one shot time (approx.
50 ms) in response to the input. If this buzzer should not be activated, set “operation confirmation buzzer = OFF” either by
changing the setting of the configuration menu or the configuration flag by the serial communication command.
(Note) When the command “X” is received, “ACK”(transaction completion) is returned even if the asynchronous shutter
mode is not selected or the menu is displayed (in the setting condition where the asynchronous shutter operation is
disabled by the command “X”).
(Note) Since the command is executed through the serial communication, it does not quickly act unlike a normal trigger
signal. Therefore, it is recommended to use the commands only when no immediacy is required, for example, in
the case where the operation of the camera is checked for setting, or the moving velocity of an object to be shot is
extraordinary slow.
(16) Command “ARESET”
Function: Command for operation reset (All RESET)
Transmission from host: STX: “ARESET”: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
This command is used to reset the camera to the initial power-on state.
(Note) This command responds to the operation when the camera is restarted after the power is turned off. The data
stored in EEPROM are not lost.
(Note) Only this command is received in the operation modes of “Group 2”, “Group C” and “Group D”.
(17) Command “WID”
Function: Command for writing camera ID (set by user) (Write ID)
Transmission from host: STX: “WID”: character string with 0 up to 15 characters: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
The acceptable characters are English 1 byte characters (both upper and lower cases) and some special symbols as
shown below:
