6.3.1 (c) External Synchronization ( HD timing details )
FIGURE 18.HD timing details
Note: The pulse width of Ext. HD requires between 48clk to 166clk. HD can not be reset directly.
6.3.2 Input of external trigger
The external trigger signal can be by means of pin 5 on the 6-pin connector (TI=0) or pin 11 on the 12-pin
connector. (TI=1). Here it should be 4.0 Vp-p ±2.0 V from a 75
Ω
source.
The factory setting is TTL. For 75
Ω
termination SW301.1 should be ON.
6.3.3 Output of XEEN
The XEEN signal is 4.0 Vp-p from a 75
Ω
source.
6.3.4 Output of HD/VD signals
HD input and VD input of D-sub 9-pin can be changed to HD and VD outputs by selecting internal switches, SW302
and SW303. The output level is 4 V p-p.

Operation Modes
This camera can operate in four primary modes.
1. TR=0
Continuous Mode.
Pre-selected exposure.
2. TR=1
Edge Pre-select Mode.
Pre-selected exposure.
3. TR=2
Pulse Width Control Mode.
Pulse width controlled exposure.
4. TR=3
Sensor Gate Control
Strobe illuminated exposure with delayed read out
The triggered shutter in EPS and PWC mode can be HD synchronous or HD asynchronous accumulation. Refer to
Section 6.4.1 on page 14 and Section 6.4.2 on page 16.
