Power management
The NTC-6200 Series router can be configured to enter or return from a low power 'sleep' mode. You can configure this to occur
automatically after a timer has expired, by the status of the ignition pin, a combination of timer and ignition pin status or by manually
triggering sleep mode.
During the sleep state, the NTC-6200 Series router is effectively powered off. That is, it has no ability to communicate wirelessly or
process any information. When in sleep mode, it draws approximately 5mA current at 12V. When sleep state is triggered, the NTC-
6200 Series router takes approximately 30 seconds to enter low power mode. When the wake up sequence is initiated, the router
takes approximately 2 minutes to return from the sleep state. This is because returning from sleep state involves a full boot up
sequence.
Ignition pin
The third pin on the 6-way terminal connector is a dedicated input called "Ignition". This input is intended for connection to an
ignition switch in vehicular applications or where an input to switch the device to a sleep/wake mode is required.
The Ignition input threshold voltage is around 3V. The input responds to a high input state (above 3V). A signal below this level is
considered as a low state. If the software is configured to activate in the low state, for example 0V, it must still have the high state
above 3V to turn it off.
Note: There is a period of about 10 seconds after sleep state has been triggered where the ignition line cannot be
monitored. Please take this into account when designing your ignition power on system.
To begin using Low power mode, set the Low power mode functionality toggle key to the ON position. Extra settings are displayed.
These settings, including the enabling or disabling of Low power mode functionality, only take effect when you click the Save
button.
