In this first lesson, you will go through the process of unboxing your computer on module and carrier board and assembling the hardware. The following GIF illustrates what you will end up with:
Iris Cable Setup GIF
A block diagram of the system setup and its connections is presented below for reference.
System setup block diagram
| List of items required |
|---|
| VGA display/monitor and DVI to VGA adapter |
| Accessory kit : |
| - 12V 30W power supply |
| - USB-Serial converter |
| - IDC to DB9 adapter cable (1) |
| - Null modem cable (2) |
| - Ethernet cable |
| USB keyboard and mouse |
(1) As an option to buying the IDC to DB9 adapter, you might assemble one by following the instructions provided on Assembling Serial IDC to DB9 Cable.
(2) The null modem cable comes with the Carrier Board Accessory Kit and it is meant to connect the USB-Serial converter to the IDC to DB9 adapter cable.
A headless setup is possible, though in the Quickstart Guide we will always assume that you have a recommended display attached to the carrier board. If you proceed without a display, skip the lessons that make use of it at your own discretion. As an option, you can follow the Torizon Documentation - just be aware you will not find a walkthrough as thorough as this guide.
Note: The DVI video output is configured to provide an analog signal by default in the Colibri family. Please make sure that your DVI adapter has the analog pins available - see DVI-A or DVI-I for more details.
Note: The Colibri iMX7S has only one USB port. On the Iris Carrier Board, it is available through the micro USB connector (X12).
Note: This Quickstart guide supports only Colibri iMX7 eMMC (that is, the 1 GB version) since raw NAND-based modules are currently supported only by experimental releases of Torizon.
Note: Carefully read this module's cover page clicking on "Module 1: Unboxing and Bring-up" on the left menu bar before starting this lesson.
Remove the Iris Carrier Board and the Colibri Computer on Module from the blisters. Insert the computer on module into the X1 connector of the Carrier Board as tight as possible, with the module inclined ~30 to 45 degree in relation to the carrier board.
Connecting the computer on module to the Iris Carrier Board
Warning: Make sure that the module is well connected to the carrier board. The image below has some checkpoints highlighted.
Computer on module connected to the Iris Carrier Board
Connect the DB9 to IDC adapter cable to the X13 connector on the Iris.
Note: The adapter is included in the Toradex Cable Kit, the standard we used is normally called DTK or Intel standard.
IDC header connected to the Irisa Carrier Board
Connect your host machine to the adapter cable using a serial cable or Serial to USB converter.
Serial setup for the Iris Carrier Board
Connect the VGA display/monitor to the X4 connector through the DVI to VGA adapter. Note: The DVI output only has the analog signal available on the Colibri iMX7. Please refer to the FAQ section at the end of this lesson for additional information.
Connect an Ethernet cable to X15. Note: Ethernet network must provide DHCP and Internet to the module.
Connect a USB keyboard to X11.

This FAQ section is meant to provide additional information for the getting-started readers, therefore it may be skipped without prejudice to the progress of the guide.
