8.2.6. The WLU indicates that each IEEE 802.3 interface is operational and electrically connected to
another IEEE 802.3 device (or compatible) by setting to a logic high state the Ethernet Activity
Discrete.
Discrete.
8.2.7. The WLU indicates that the selected RF Interface is operational and connected to a ground
station by setting to a logic high state the RF Activity Discrete.
8.2.8. When the selected RF Interface is operational and connected to a ground device the WLU
momentarily sets the RF Activity Discrete to ground to indicate network traffic on this interface.
8.2.9. The WLU provide an open/ground discrete output interface for indicating internal power rail
status.

Position Pin Discretes
The WLU shall have three position pins defined. The WLU shall select its IP address and core
functionality (TWLU or CWLU), based on position pin grounding. Table 8-1 shows function and IP
address assignments by position pin settings.

Antenna
The WLU uses one standard TNC female type connector for the 802.11 antenna interface. The WLU is FCC
certified with multiple Wi-Fi antennas listed in Table 7-1. The RF cables used to connect the unit to the
antennas should be chosen to minimize weight and signal attenuation. The Wi-Fi RF connector is labeled J2.
