ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Connect Tech
COM Express carrier assemblies, it is recommended
that ESD safety precautions be observed. ESD safe
best practices include, but are not limited to:
•Leaving circuit boards in their antistatic
packaging until they are ready to be installed.
•Using a grounded wrist strap when handling
circuit boards, at a minimum you should touch a
grounded metal object to dissipate any static
charge that may be present on you.
•Only handling circuit boards in ESD safe areas,
which may include ESD floor and table mats,
wrist strap stations and ESD safe lab coats.
•Avoiding handling circuit boards in carpeted
areas.
•Try to handle the board by the edges, avoiding
contact with components.

INTRODUCTION
Connect Tech’s GMSL camera platform is an expansion board that allows up to 8 GMSL cameras to be
connected to various Jetson platforms. The NVIDIA Jetson® GMSL Camera Platform has user selectable
options to interface with either GMSL1 or GMSL2 protocols at different operating frequencies. Power to
the cameras is provided by PoC (Power over Coax) so all the data, control signals, and power are sent
through a single 50 Ohm Coaxial cable. This allows for flexibility in cable routing and ease of installation
in automotive applications.

[S1] GMSL Switch Summary & Locations
This must be set correctly at power up! This signal is sampled once at boot up and cannot be
changed on-the-fly. The GMSL mode cannot be changed in software. The setting applies to all
8 channels, so you cannot mix GMSL1 and GMSL2 cameras on the same board.

TYPICAL INSTALLATION AND USAGE
Software setup
Prior to hardware installation, make sure you have the correct software installed on the Xavier Module.
Installation instructions can be found at https://connecttech.com/resource-center/kdb373/. All other
GMSL and GMSL2 (MIPI) cameras should work with proper software and firmware configuration as long
as the power requirements match what JCB002 provides. Power to the cameras can be disabled by
setting CAM0_PWDN (UART4_CTS) low. There is a 100k external pull up resistor on this pin, so it is not
necessary to configure the pin for always on operation. This enables the 2.8V power rail which powers
the logic levels on the deserializers.
1. Ensure all external system power supplies are off.
2. Make sure S1 is set to the correct GMSL mode for the cameras connected.
3. Connect camera(s) to miniCoax connector(s).
a. Optionally connect an external 12V DC power supply to J3.
b. The external power connector provides unregulated power to the cameras. Do not
exceed 14V on this input.
4. Switch ON the Power Supply. DO NOT power up your system by plugging in live power.
Note: 10mm M3 extension standoffs are recommended to be added to the 18mm standoffs provided with the Rogue carrier for
clearance.

POWER & THERMALS
External Power Connector
Although +12V is available on the Rogue Carrier (Rev. C and higher), the JCB002 allows for
external power to be provided to the cameras. The voltage is unregulated and could
potentially damage cameras if they cannot handle the input voltage.
Test setup:
•Rogue AGX minimal setup carrier powered at +13V/XXXA
•Up to 8 ECON NileCAM30 connected.

Note:
1. Since the Rogue carrier can be populated in many different configurations, the current consumption is listed excluding power
needed to run the Rogue (and Xavier Module) itself, i.e. the value in the No Cameras Connected section.
2. Minimum current is defined as when the cameras are not streaming, maximum is the peak surge current and typical is current
consumption during streaming.
