Figure 4. Hirose Power Connector Diagram
An AC adapter is provided with a cable that connects to the back panel of the camera via a supplied
hybrid adapter cable. The adapter cable mates with the connector labeled POWER/AUX, and provides a
snap-fit connector of the Hirose HR10A-7P-4P(73) series on the fly end, as well as supplies SMA
connectors for the Sync and Trigger logic connections. The mating Hirose connector is on the auto-
selecting AC adapter which plugs into 100-240 VAC (47 Hz - 63 Hz) mains; international mains adapter
blades are available.
The Hirose connector pr and - power across the 4 contacts. Pins 1 - 2 are DC + and pins 3-4 are
DC -. DC- is isolated from ground by a protection resistor, capacitor, and ferrite slug, yet it is not
forbidden to ground the negative supply (review this connection if unusual noise coupling is noticed). If
you are wiring to this connector, a handy hint is that commercial connectors will emboss or otherwise
label the pin numbers onto the connector to insure there is no confusion as to which side of the indexed
connector you are viewing.
NOTE: Insure wiring polarity is correct. Reversed connection is a
common cause of damage.
If the supplied AC adapter is being used, insert the power connector on the provided AC
adapter (PN 8000-0726) into the camera power adapter cable until snap-locked. Do not
make or break this connection while power is being supplied.
If the supplied AC adapter is not being used, test the power source for proper voltage, polarity, and pin
connections before connecting the power cable to the camera. Do not exceed the voltage maximum or
damage may occur. The power source used must conform to the power specifications with regard to
maximum power and ripple, etc. to ensure proper camera performance.
Regardless of the source of power (supplied AC adapter, lab power supply, etc.) the best
practice is to supply and remove power at the source rather than at the load. Therefore,
when using the supplied AC adapter, make the connection at the wall last when powering
the camera and first when removing power from the camera. Do not make or break the
connection at the camera or on the cable while power is being supplied.
If using the trigger input or sync output, connect the appropriate adapter cable to the external device. The
Trigger and Sync is compliant to 3.3V CMOS logic in terms of supply voltage, crossover points, and
loading. Safety is built in should a compatible trigger be applied while the camera is not powered. The
trigger, synch, and video shells are tied to Digital ground through individual inductors. V- is tied to
