· Power connector is plugged in and supplying voltage between 7–36 V.
Note: Although the RV50 Series gateway operates in the range 7–36 V, low voltage standby
mode is enabled by default (as of ALEOS 4.5.2), so in order to avoid the gateway powering into
standby mode, ensure that it is supplied with more than 9 V at startup. (If desired, you can
change the low voltage standby settings once the gateway is operational.) If the Power LED is
red, the gateway is in standby mode.
· Ignition Sense (pin 3) is connected to the battery or power source (see
