3.1 12-Pin Connector
The 12-pin Hirose connector is located on the rear
plate of the camera. All ground signals on pin # 1, 3,
5, 8, 10, and 12 are common grounds. Although
+12 V DC input is recommended on pin #2, this
camera should wit12 V
±
1V input voltage.
Make sure to set the NRM/ASM switch to NRM
position on rear plate for external HD and VD
locking. Apply TTL signal on HD (pin # 6) and VD
(pin # 7) inputs if necessary, refer to section 4 for
details. Figure 3 below shows a top view of the 12-
pin Hirose connector.

3.3 Shutter Speed Dial Switch
Shutter speed dial switch is located on the rear
panel (Figure 5). The camera default setting is at
ASM. For normal shutter speed, it has 9 different
shutter speeds to select from. Position # 0 is
