2.2.4 Ground
The design uses one single ground on all PCBs. Each PCB will be multilayer with at least 1 solid ground
plane. Each of the flex connections between PCBs will also have a complete Ground the full width of the
flex. All mounting holes are through hole plated with pads and directly connected to Ground with no thermal
relief. Flood fills top and bottom are also connected to Ground.

3 DESIGN DETAILS
3.1 Electrical Design
3.1.1 Power supplies and Thermo-Electric Cooler (TEC)
Unit input power specification is +12V ±10% with a maximum of 6.6 Watts power dissipation with the TEC
cooler disabled. Additional inrush current (peak power) is required when the TEC power is switched from
low to high. Peak power < 13 Watts. The total, maximum steady state, unit power dissipation is 7.6 Watts.
The default set point for the TEC cooling is +5oC. The TEC power supply is automatically adjusted to reach
the set point temperature, with a limit of approximately 1 Watt.
At low ambient temperatures or with additional heat sinking the TEC efficiency is increased and
consequently the power required to achieve the set point is decreased.
3.1.2 CCD216 Image Sensor
-768*244 active element
-11.5um x 27um pixel size
-Fully hermetically sealed case with inbuilt TEC
-1 output
-Frame rate = 59.94 Frames/Second (fps)
-Readout noise = 45e-
-13.5 MHz pixel clock
Refer to e2v CCD216_BI datasheet for further details, available at www.e2v.com.
The CCD216 is an Electron Multiplying device which allows the application of Electron Multiplication
(EMGain).
3.1.3 Communications Interface
The RS485 communication interface has the specifications as listed in Table 5: RS485 Settings.
Baud rate:
115200 bps
Data bits:
8
Parity:
None
Stop bits:
1
Flow control:
None
Table 5: RS485 Settings
These settings are fixed and cannot be altered.
The RS485 signals have an internal 120R termination resistor.
3.1.4 Analogue Video output
The camera produces interlace analogue video in the 525 line NTSC mono format, with no chrominance
subcarrier, ITU-R BT.1700 (59.94Hz, 2:1 interlace, 4:3 aspect ratio).
The video output has a 75R source impedance.

3.1.5 Trigger Output
The trigger output has a 510Ω source impedance with a 100 microsecond 3.3V pulse synchronised to the
video out Vertical Sync pulse.
3.2 Functionality
3.2.1 Automatic Gain Control (AGC)
The AGC is enabled by default.
The AGC has 3 input parameters that the operator can adjust to customise the camera operation for the
ambient light environment, namely AGC Speed, AGC Peak/Average and AGC Auto Level.
AGC Auto Level is the image intensity that the AGC will attempt to achieve as an average/peak across the
scene. This setting can be adjusted alongside AGC Peak/Average to achieve desired light level.
The AGC has two variables used to achieve the desired light level, namely the Electron Multiplying (EM)
Gain and the IRIS aperture.
When the Auto IRIS is enabled in a low ambient light scene the AGC will fully open the IRIS shutter before
adjusting the EM Gain, whereas in a high ambient light scene the AGC will reduce the EM gain before
closing the IRIS shutter.
3.2.2 EM Gain
If the AGC is disabled the Electron Multiplication Gain can be manually adjusted using serial commands as
detailed in section 4 Serial Communication. It should be noted that the EM Gain Maximum value stored in
the EEPROM must not be exceeded.
**If the EM Gain Maximum is exceeded the camera may be permanently damaged.**
The EM Gain Maximum value can be read back from the camera using a GET command as detailed in
section 4.4 Query Commands.
3.2.3 Exposure Period
The exposure period is fixed at approximately 15.74 milliseconds.
3.2.4 Unit Serial number
Can be read from the camera’s EEPROM. Refer to section 4 Serial Communication for further details.

4 SERIAL COMMUNICATION
4.1 Overview
For version 2.7 of the Micro firmware, the Power on default settings for camera serial port are;
-115200 baud
-1 start bit
-8 data bits
-1 stop bit
UART message format from Host to camera
Command
Data 1
Data 2
........
Data n
ETX
Chk_Sum
The first Byte is the command to the Microcontroller in the camera, following bytes contain data required by
the command, and the ETX byte terminates the command. 0x50 is always used to terminate the command.
An additional check sum byte may also be required to be sent by the host if check sum mode is enabled.
UART message format from camera to Host
Data 1
Data 2
........
Data n
ETX
Chk_Sum
All or none of the above bytes may be sent in response to commands from the host depending on the
commands sent by the host.
An optional mode of operation is included in the firmware for command acknowledge. Once enabled the
camera will respond to all commands send by the host. After the camera has received and processed the
command from the host, a single command acknowledge byte will be sent at the end of transmission (ETX)
i.e. should the host command require data to be sent from the camera then the ETX byte will be sent at the
end of the requested data.
Another optional mode of operation is included in the firmware is for check sum operation, this mode
should only be used when the command acknowledge mode is enabled. Once the check sum mode is
enabled the camera will only act upon commands that are received with the correct check sum byte sent at
the end of the command packet. Note that if the check sum feature is not enabled check sum bytes may
still be sent at the end of a command packet, the command will be processed and the check sum will be
ignored. The check sum byte should be the result of the Exclusive OR of all bytes in the Host command
packet including the ETX byte.
When check sum mode is enabled data returned from the camera will include an echo of the checksum
from the host command
By default the camera will boot up with both command acknowledge and check sum operation disabled.
It is intended that the camera be operated from a higher level perspective whereby complete UART
messages or groups of UART messages are used to achieve required camera functionality.
Bits in registers that have not been identified in the documentation should be ignored.
Once a command has been received by the camera all sub sequent commands from the host will be
ignored until the command has been processed.
