(Note)
All the items of the FR data are “0” as factory default.
(Example) If “MF=H’0008.0003” is displayed on the menu screen, the camera is in the following state (converting the
numbers to ones in binary system):
H’00=B’00000000, H’08=B’00001000 and H’03=00000011 are substituted to the above numbers.
CR=B’0000000000001000, FR=B’0000000000000011
………
CR(3)=FR(1)=FR(0)=1, All other bits = 0
(Where CR(n) and FR(m) represent the nth bit of CR and mth bit of FR respectively)
Based on 1 or 0 of these bits and the information in the above table, the user can know that the camera is in the
state of “8bit format”, “ASYNC” and “Enabled pulse width control”.
[Explanation]
The setting values (1 or 0 of respective bits) of (CR) and (FR) vary according to the change to be made using the switches
on the rear panel of the camera. The operation modes that cannot be changed by the RS-232C commands can be
changed by altering the bits of (CR) and (FR).
(Example 1) When a change is made from the continuous shutter mode
→
asynchronous shutter mode,
“MF=0000.0000” is replaced by “MF=0000.0001” (ASYE bit = 1).
(Example 2) When CR (0) is changed from 0
→
1 using a serial communication command, “ON” on the menu display is
replaced by “OFF” (MIND=1).
