66As inputs:• Use LVTTL (3.3V) levels.As outputs:• - use as an open collector with 100 ohm limiting resistor.• - Maximum Sink Current = 50mA for VCE_sat <=0.3V. Maximum VCE = 30VDCRelay Output ControlSets the state of the Relay output, Activate means the relay coil is energized and contacts become closed.Digital Output ControlThose controls are only available when the Digital I/O Select is set to Output. Clicking on “Activate” means that the opencollector transistor is set into conduction (saturation). The transistor can then sink up to 50 mA . Conversely, when it isdeactivated, the transistor stops conducting and the collector is left floating through the internal 18.2 K pull-up resistor3.11 GPSThe Fusion LTE Cellular Broadband Router contains a standalone, high-accuracy, high-report-rate (12 satellites with WAASand Differential Correction, 1 report per second) GPS receiver.From the main navigation panel, select GPS for access to the screen.3.11.1 STATUS ConditionIndicates the quality of received GPS reportsNo Fix / Invalid The GPS receiver has not yet acquired enoughsatellites to provide an accurate position, or theprevious Estimated Position is over 3 minutesold.Standard GPS Fix GPS position is reported using no additional
