3. Camera Functions
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), VD/VINT
(pin # 7) inputs if necessary, see section 4 for
details. Figure 3 below shows a top view of the 12-
pin Hirose connector.

3.2 Shutter Speed Dial Switch
Shutter speed dial switch is located on the rear
panel (Figure 4). For normal shutter speed, it has 9
different shutter speeds to select from. Position # 0
is standard scanning speed, 1/60 second. As
“Position #” goes higher, the shutter speed goes
higher and the video becomes darker. For
asynchronous reset shutter speed, an ext. TTL
signal is required to trigger the camera. 8 different
shutter speeds can be selected. Custom controlled
shutter speed can be applied at position #9, see
section 4 for details.

3.3 Normal and Asynchronous Capture Mode (NRM/ASM)
For normal operation, either with or without shutter speed, NRM should be selected. For asynchronous capture
and strobe applications, ASM should be selected. Detailed timing diagrams are shown in section 4.
