4 characters are returned as the electronic shutter 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 electronic shutter exposure time is set using the shutter switch number on the connector
panel:
Example) If the shutter switch is set to “4”:
“I4..”
●
In the case where the electronic shutter exposure time is set by the shutter switch number via a RS-232C
command:
Example) If “3” is specified for the shutter switch, :
“S3..”
(3) Command “G”
Function: Command for setting gain
Transmission from host: STX: “G”: MGC setting value: AGC setting value: (VRT setting value): (VRB setting value):
OFFSET setting 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 codes in the hexadecimal system are used for the data setting values of MGC,AGC and OFFSET.
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.
Example) if only MGC is changed to Level 90 (decimal):
STX: “G”: “5A”: “.”: “.”: “.”: “.”: ETX
(4) Command “S”
Function: Command for setting shutter mode and shutter exposure time
Transmission from host: STX: “S”: “A” or “M”: “H” or “L”: “N” or “P”: 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” or “P”: Exposure time: ETX
*1 *2 *3 *4
*1 A: Asynchronous shuttr
M: Continuous shutter
*2 H: High speed shutter
L: Low speed shutter
*3 N: Normal scan
P: Partial scan
*4: Exposure time
The format of “Exposure time” complies with one of the followings:
a. 4 characters representing 2-byte number and corresponding to the hexadecimal system
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 using 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 one using the rear panel of the camera:
STX: “S”: “.”: “.”: “.”: “0000”: ETX
(Note) When the exposure time is externally set with the command “S”, the exposure time of the camera will finally be
locked to the position specified by the command or to the value directly specified. This locked state is released
when the exposure time is set to “0000” by RS-232C again as described above.
To release this locked state without using RS-232C after specifying the exposure time using RS-232C, perform
the procedure of “Read out of factory default” as described in the Section (6-9).
