CFHEADER Module Features

1. PWR - Power LED
2. 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.
3. CFNET connector for connecting IO modules.
4. 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.
   
   
5. BOOTSEL - Boot selection button for uploading the firmware.
6. 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.
7. 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.
8. 12~24VDC power input.
