mangOH Yellow User Guide 2.3 Initial Setup To begin using the mangOH Yellow, set up your hardware and software: 1. Verify the SW403 dip switch block pins are set correctly: a. Remove the protective film from the dip switch block: Remove this film Figure 2-2: Remove Protective Film b. Make sure all the dip switches are OFF (factory default mode). Figure 2-3: Dip Switch Positions (Factory Default) 2.
2.3: Initial Setup 5. Power up the mangOH Yellow: a. Connect the selected power supply—Use a micro-USB cable to connect the mangOH Yellow USB connector to your computer or AC adapter, or use a 15-pin cable to connect the expansion connector to an external device that will provide power.
mangOH Yellow User Guide When the mangOH Yellow is powered, the Power/Network/Cloud LED turns solid green, then turns yellow (when the cellular radio powers on), and then the generic LEDs begin blinking in sequence when the module has finished booting up. Generic green LED Power/Network/Cloud (tri-color) LED Generic tri-color LED For this getting started procedure: The jumper must be on these pins and The cable must be plugged in *this* connector ("USB").
2.3: Initial Setup 7. Wait for the device to enumerate (1–4 minutes, typically). (Windows) You can confirm the device has enumerated by viewing Display Manager—the device appears under Modems, and its COM ports appear under Ports (COM & LPT): Figure 2-8: Windows Device Enumeration 8. Confirm the connection between the computer and mangOH Yellow is working: a. Open a command prompt window. (e.g. Linux Terminal window, Windows command prompt). b.
3: Hardware Setup and Features 3 This chapter describes: • How to install various components on the mangOH Yellow • Available connectors • How to configure and control features using connectors and switches 3.1 Power Supply Sources The mangOH Yellow is powered via the board’s USB (CN802) micro-USB connector, the expansion connector, or an optional external backup battery. The micro-USB connector can connect to a computer’s USB port or, if greater power is required, to an AC adapter.
3.1.1: Select Power Supply 3.1.1 Select Power Supply To select the primary power supply: 1. Place the mangOH Yellow with the dip switch block facing up (module facing down) and locate the power select (PWR SEL) jumper pins (CN801). USB power (jumper on pins closest to board edge) Figure 3-2: Power Supply Selector 2. Select the preferred power source: · USB connector—Place a jumper across the two pins closest to the edge of the board.
