====== CFHEADER Module Features ======

{{ .::cfh_module_features.png?200 }}

  - PWR - Power LED
  - STA - Status LED - Toggles on every 500 round trip I²C communications with the connected CFNET IO modules.  This not only provides a heartbeat indicator, but also a visual indication of the speed with which the CFHEADER module is able to communicate with the connected CFNET IO modules.
  - CFNET connector for connecting IO modules.
  - ADDR - Address DIP switches.  Update to 8 CFHEADER modules can be connected to a single USB host as long as each module is configured with a different address using its ADDR DIP switches.\\ \\ {{.:cfh_addr.png?}} 
  - BOOTSEL - Boot selection button for [[cfnet:cfheader:firmware:index|uploading the firmware]].
  - USB Type B Connector - Although this connector supplies power to the CFHEADER, it is not sufficient to power the CFNET IO modules.  Therefore, it is best to always connect 12~24VDC also.
  - USB Molex Connector - This provides a more permanent and robust USB connection than the USB Type B connector.  This USB connector does not supply any power, so connecting 12-24VDC is required.
  - 12~24VDC power input.
