1.5 Color Spectral Response
A typical spectral response of the color 2M280 and 4M140 cameras, with D263 cover glass
and color filters is shown below. Flare color CXP models come standard with an IR cut filter
in the optical path to obtain good color separation. The cutoff wavelength of the filter is
645nm.

2.1 Mechanical Specifications
Summary of mechanical specifications are shown in table 3. Mounting holes on all sides of
the camera provides many mounting options.
Specification Description
Size 63.5 mm x 63.5 mm x 44.1 mm
Weight 318 g
Mounting Holes Bottom - 1x 1/4"-20 (tripod)
All sides - 2 x #8-32, separation 1"
Power Connector 12-pin threaded Hirose
Mating connector part # HR10A-10TPA-12S(73)
Video Output 2 x standard BNC

2.2 Lens Adapter
Aluminum C-mount lens adapter precisely calibrated to standardize focal length to sensor,
see figure 6.
Figure 6. Lens adapter
IO Industries Inc. www.ioindustries.com Revision 2.0

The position of the lens adapter is set using specialized equipment to ensure the proper back
focus of each camera. Three set screws (M2.5 - 1.3mm hex) on the front of the adapter are
used to firmly hold the ring adapter in place. In most cases it is not recommended to change
the position of the adapter ring. In rare cases the back focus can be adjusted to improve
image sharpness when using lower cost zoom lenses or custom optics.
The size of adapter ring is T-mount, with standard threading. It is possible to use a T-mount
extension tube with T-mount lenses; commonly Telephoto Zoom and Telescope lenses.
Between the adapter ring and the sensor there is another section of C-mount threading. With
a spacer ring (Edmund Optics spacer ring kit G54-461) this section can be used for a CSmount lens. This section can also be used to insert a filter in the optical path of the camera.

2.3 Power
Flare CXP cameras are powered using a 12-24 V ± 10% DC power source. The power
connector is shown in figure 7, and the pinout is shown in table 4.
The camera can optionally be powered over the coax cable (PoCXP) from a compliant frame
grabber on the Link 1 connector only. It is recommended to remove the power adapter from
the camera power connector when using the camera in a PoCXP configuration.

2.4 External Triggers
There is one opto-isolated input on the power connector, pin 1. Only ground must be
provided as a reference for the input. The voltage range on the input is 4.5 to 7.5 V, and the
input delay is approximately 100 ns. The input current range is 6 to 12 mA. The circuit
diagram for the opto-isolated input is shown in figure 8.
Figure 8. Opto-isolated input circuit diagram
The opto-isolated input circuit uses a high-speed photocoupler from Renesas Technology
Corporation, part # PS9821-2. Note TTL-IN2 is not used.
There is one opto-isolated output on the power connector (pins 10 and 9). Power (4.5 to 15
V) and ground must be provided for this output. The maximum output delay is approximately
1 µs. An external pull-up resistor is not required, but if one is used it must be greater than 2
kΩ. The circuit diagram for the opto-isolated output is shown in figure 9.

Figure 9. Opto-isolated output circuit diagram
