Digital Input Pins – Source of Inputs
Figure 23 - Input Sources (Digital)
Digital input pins can receive inputs from themselves, any other digital input or output pin, or the
following internal sources listed in the table below. Up to four input sources can be combined
using the boolean operator AND or the boolean operator OR. All input processing is completed
before the pin is evaluated.
Input Definitions – Virtual Digital Inputs
Input Pins Any Input pin (physical or virtual) *
Output Pins Any Output pin (physical or virtual) *
Relay In
Reflects the state of the relay input contact
(discrete input) that is available on the
SkyRouter platform
GPS Status
Reflects the state of the internal GPS receiver
as shown on the Navigation Unit Configuration
Screen. 1 = OK; 0 = GPS unavailable
WWAN Status
Reflects the state of the Wireless WAN as
reflected on the Wireless Configuration Screen.
1 = Enabled; 0 = Disabled
* Caution – Be sure that pins assigned to other pins are of the same type. Example: Analog to
numeric is OK but Analog to Digital will yield unpredictable results.
