3Power Over CoaXPress (PoCXP)
The Pollux CoaxPress Protocol cameras comply with “Power over CoaXPress” which
enables power to be supplied to the camera through the CoaXPress cables. Power
must be supplied via both CoaXPress cables in order to utilize the PoCXP capabilities.
If you plan to use this function, please be sure that the frame grabber board you
are using also complies with this specification. We can guarantee the Radient frame
grabber from Matrox are able to supply a sufficient power for the camera’s
operation. Alternatively, the camera can be powered via a separate power supply
connected to the 12-pin Hirose Connector.
Thus, the camera can optionally be powered over the coax cable (PoCXP) from a
compliant frame grabber on the CH1 and CH2 connectors. It is recommended to
remove the power adapter from the camera power connector when using the
camera in a PoCXP configuration.
3.1 CXP Connector
The CoaXPress protocol includes an automatic link detection mechanism (Plug and
Play) to correctly detect the camera to the CXP Frame Grabber connection. The
connection between the camera and CXP Frame Grabber uses a coax (also known
as ‘coaxial’) cable and provides up to 6.25 Gbps bit rate per cable.
The CoaXPress connector on the Pollux CXP camera complies with the CoaXPress
standard and the following table 5 shows the channel assignments.

3.2 Trigger Input Design
There are two input triggers and an output trigger on the power connector (pin 5,
7 and 9). The inputs and output are connected to Opto-islolated I/Os in the camera,
with an input/output voltage range of 2.5 V to 5.0 V. There is a 510 Ω series resistor
in the input path, a 680 Ω series resistor in the output path. The circuit diagram
for the trigger inputs is shown in Figure 4.

4Camera Functions
4.1 CoaXPress Output Format
The CoaXPress downlink outputs can run at CXP 6-4 (25 Gbps). The frame rate
will automatically be adjusted to reflect the change in output bandwidth as shown
in table 7.
CXP Connection
Output Bandwidth
Max Frame Rate
CXP 6-4
25 Gbps
30 fps
Table 7. Frame Rate
The output pixel depth is 8-bit and 12-bit.
To be easy to use and convenience, the camera always powers up in a CXP-6 with
4 connections mode while supporting default frame size, period and exposure
settings. Thus, user no needs to change CXP Connection command for the max
frame rate, 30 fps of camera after a successful connection.

Page 16 of 24 Manual 1.5
OZRAY Pollux Series - 50M CXP
4.2 Frame Rate and Exposure
The frame rate in free-run exposure mode is controlled with the FrameRate
command. The frame period is specified in microseconds. The minimum frame
period of the camera (maximum frame rate) is determined by the output format
and the resolution.
The relation between these parameters is :
GLOB Time = 149.64 μs
Line Time = 5.35 μs
Read Out Time = 32.2 ms
(at 830 Mbps LVDS Clock, Full Frame)
The total frame time is :
Frame Time = GLOB Time + Read Out Time
Our product automatically calculates maximum exposure according to the frame
rate. For example, in case of 30 frame rate, frame time is 33,333 s and the
exposure time is 33,183 μs.
The GLOB time depends on the output format and the LVDS clock period. The
readout time of a frame is equal to the number of lines in the output image.
The camera re-calculates the allowable range for the frame period when the output
format or resolution is changed. The camera will set the frame period to the new
minimum. The range for the exposure times is also re-calculated, and if any current
exposure time is outside of the new range it will be set to the maximum.

OZRAY Pollux Series - 50M CXP
4.3 Camera Mode
The exposure mode of the camera is controlled using the Camera Mode
command, and there are three options:
•Free-running
•External Trigger Timed
•External Trigger Width
4.3.1 Free-running
In this mode, a rising edge of internal trigger the start of integration and readout.
The integration time is defined by a Exposure Time Command. The sensor
autonomously integrates during this predefined time, after which the GLOB starts
and the image array is readout sequentially. A falling edge on the synchronization
pin does not have any impact on the readout or integration and subsequent frames
are started again for each rising edge. Figure 7 shows the relation between the
internal trigger signal and the exposure/readout timing. If a rising edge is applied
on the internal trigger before the exposure time and GLOB of the previous frame is
complete, it is ignored by the sensor.
Figure 7. Free-run exposure timing

Page 18 of 24 Manual 1.5
OZRAY Pollux Series - 50M CXP
4.3.2 External Trigger Timed
In this mode, a rising edge on the synchronization pin is used to trigger the start
of integration and readout. The integration time is defined by a Exposure Time
Command.The sensor autonomously integrates during this predefined time, after
which the GLOB starts and the image array is readout sequentially. A falling edge
on the synchronization pin does not have any impact on the readout or integration
and subsequent frames are started again for each rising edge. Figure 8 shows the
relation between the external trigger signal and the exposure and readout timing.
If a rising edge is applied on the external trigger before the exposure time and
GLOB of the previous frame is complete, it is ignored by the sensor.
Figure 8. External trigger timing (Timed)
Exposure starts when the high-active edge of the input trigger is seen. (Also, It is
possible to use low-active edge). The trigger can be used by the CoaXPress input
trigger received on the uplink signal or the Opto-isolated inputs on the power
connector (External Trigger In0/In1). There is a GLOB time after the exposure ends,
same as free-run mode, and then readout of the frame begins. The minimum pulse
width of the input trigger is 100 ns.

Page 19 of 24 Manual 1.5
OZRAY Pollux Series - 50M CXP
4.3.3 External Trigger Width
In edge-triggered level-controlled exposure mode the exposure of the frame is
controlled by the active state of the input trigger. The frame period and exposure
commands have no effect in this mode. Timing for this mode is shown in Figure 9.
In this mode, exposure starts when the input trigger transitions into the active
state. Exposure continues until the trigger transitions into the non-active state. The
active state can be set to high.
Figure 9. Edge-triggered level-controlled exposure timing
There is a GLOB period after the sensor is triggered to stop integration before the
readout starts. When the sensor enters this GLOB period, there is a portion of time
where the photodiodes are still being exposed to light before the charge is
transferred to the storage elements. For programmable exposure modes, this time
is included in the exposure time value. The minimum pulse width is 150 µ s.
Exposure of the next frame cannot start until the readout of the current frame
begins. Also, exposure of the next frame cannot end during the readout of the
current frame. To ensure this condition is met the camera does not look for the end
of exposure transition until the readout of the current frame has completed.

OZRAY Pollux Series - 50M CXP
4.4 Image Region of Interest
The Image Region of Interest (ROI) feature allows you to specify a portion of the
sensor array. You can acquire only the frame data from the specified portion of the
sensor array while preserving the same quality as you acquire a frame from the
entire sensor array. With the ROI feature, you can achieve increased frame rates
by decreasing the height(i.e Vertical or Y-axis) of the ROI; however, decreasing the
width(i.e Horizontal or X-axis) of the ROI does not affect the frame rate. The ROI
is referenced to the top left corner [origin (0, 0)] of the sensor array. It also
supports Multiple ROIs by 4 regions at Y-axis. Table 8 shows some sample ROI
Vertical for the reference.
On the Pollux50MCP camera, the Width parameters must be set to a multiple of
10. Otherwise, the Height parameters can be set any positive integer value.
