: Exposure time
● In the case where the electronic shutter exposure time is externally set:
When the exposure time is set in the unit of H (horizontal scan time), the exposure setting count value of the
time in H is returned.
Example) If the shutter exposure time is 16Hs
“0010”
● In the case where the exposure time is set by the shutter switch number on the connector panel:
Example) If the shutter switch is set to
“4”: “I4..”
● In the case where the exposure time is set by the shutter switch number via a serial communication command:
Example) If
“3” is specified for the shutter switch, : “S3..”

Command “G”
Function: Command for setting gain
Transmission from host:
STX: “G”: MGC set value: (AGC set value): (VRT set value): (VRB set value): OFFSET set value:
ETX
Return by camera:
STX: ACK: ETX (transaction completion) or STX: NAK: ETX (transaction rejection)
(!) This camera does not use the values in parentheses
“ . ” must be transmitted to the camera.
2 digit ASCII code in hexadecimal
“20”
～
”E0”(32 to 224; decimal) are used for the data setting values of MGC and
OFFSET.
Example) If level 128 (decimal) is set:
“80”
If level 200 (decimal) is set:
“C8”
The setting value that does not need a change should be represented by
“.” (a full stop) so that the setting value before
the command transmission is retained.
Example) if only MGC is changed to Level 90 (decimal):
STX: “G”: “5A”: “.”: “.”: “.”: “.”: ETX
(9)
Command “S”
Function: Command for setting shutter mode and shutter exposure time
Transmission from host:
STX: “S”: “A” or “M”: “H” or “L”: “N”: exposure time: ETX
Return by camera:
STX: ACK: ETX (transaction completion), or STX: NAK: ETX (transaction rejection)
The transmitting command has the following meanings:
STX: “S”: “A” or “M”: “H” or “L”: “N”: Exposure time: ETX
*1 *2 *3 *4
*1 A: Asynchronous shutter
M: Continuous shutter
*2 H: High speed shutter
L: Low speed shutter
*3 N: Normal scan
*4: Exposure time
The format of “Exposure time” complies with one of the followings:
a. 4 characters corresponding to the hexadecimal which represents 2-byte number
b.
4 characters of “S” “0 to 9” “..” for externally specifying a shutter position (2 full stops of “.” in the last are
mandatory.)
● In the case where the electronic shutter exposure time is externally set:
When the exposure time is set in the unit of H (horizontal scan time), the exposure setting count value of the time in H is
set.
Example) If the shutter exposure time is 16Hs:
STX
: “S”: “.”: “.”: “.”: “0010”: ETX
● In the case where the exposure time is set by the shutter SW number on the connector panel:
Example) If the shutter SW is set to
“4”:
STX: “S”: “.”: “.”: “.”: “S4..”: ETX
● In the case where the exposure time is set to 3Hs in the asynchronous/high speed shutter mode:
STX: “S”: “A”: “H”: “.”: “0003”: ETX
● In the case where the control is returned to the setting by the shutter switch on the rear panel.:
STX: “S”: “.”: “.”: “.”: “0000”: ETX
(Note) In the case where the exposure time is externally set using S command, the exposure time is locked finally to the
position designated by S command or directly designated value. The locked state is released by setting the
exposure time to
“0000” using RS-232C as described above. To release the locked state without the use of
RS-232C after setting the exposure time by RS232C, execute
“Read-out of Factory Default” operation
(Note) The allowable range of number is as follows when in directly setting the exposure time. The operation out of
the range is not guaranteed.
In QUAD or DUAL : H
’0000 to H’023C (D’ 0 to 0572)
In SINGLE : H
’0000 to H’0478 (D’ 0 to 1144)
(where
“0” is used only when cancelling the external time setting )
