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
  - Ethernet cable
USB keyboard

As an option to buying the IDC to DB9 adapter, you might assemble one by following the instructions provided here.

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.

Step 1

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.

  • Connect the VGA display/monitor to the X4 connector through the DVI to VGA adapter. Note: The DVI output only have the analog signal enabled by default. To use the digital interface please refer to the FAQ section in the end of this lesson.

  • Connect an Ethernet cable to X15. Note: Ethernet network must provide DHCP and Internet to the module.

  • Connect a USB keyboard to X11.

  • Connect a power supply to the barrel jack X8. Attention: Double check that your power supply is within the Iris Carrier Board limits (7-27V) and that the polarity is not inverted. Also, make sure that the current capability of the power supply is enough, or the system will shutdown unexpectedly sometimes. For evaluation purposes, a 12V 2A power supply is recommended.
