STROBE
Temperature change detection input. Detects variations in the forward voltage
at the connected diode to correct the back-focus
Receives vertical camera shake correction data from 1C1401 (GYRO VERT.)
via 161403 (GYRO AMP).
Receives horizontal camera shake correction data from IC1402 (GYRO HORIZ.)
via 1C1403 (GYRO AMP).
F-value detection input. Receives the F.DET voltage detected by IC1201 (F.DET/
IRIS DRIVE) and compares this with the reference voltage input via pin 77 to detect
the F-value.

Field discrimination pulse input.
Used for initial settings and adjustment. For data communications with personal
computer.
Receives pulses which discriminate the iris detection area.
For data communications with 1C1102 (DSP), 1C1105 (EEP-ROM), 1C901(S-uP),
1C201 (VIDEO DSP) and 1C5302 (D/A CONV.).

PAL60 switch detection inputs.
Playback mode detection input. 1C1104 receives the playback mode detection
signal sensed by IC201 (VIDEO DSP) and instructs IC904 (CHARA. GEN.) to
generate the display signals and also transfers the operation mode data toiC201.
Open for models with which only normal tapes are used.
