When HMT140 Configuration Cable is connected to HMT140, it enters Config mode. In this mode, HMT140 continuously attempts to connect to the wireless network and stays connected until HMT140 Configuration Cable is disconnected or the setup has changed.
HMT140 is in Transmitter mode when HMT140 Configuration Cable is not connected, and the HMT140 power switch is turned on. When in Transmitter mode, HMT140 remains in a low power state, but will turn on, connect, transmit a UDP packet, and then go back to the low power state when it is ready to transmit.
