Figure 4 is a diagnostic screen that shows RF packets outgoing. Note that since only one
bridge is transmitting, the outgoing utilization is 100%. On the 11 Mb/s, however, the
maximum utilization is 84%, with the packet size set at 1514 (
T 1514 then <Enter>).

As well as the normal display screen, the NCL1100 has a diagnostic utility included. This
utility diagnoses the RF link; use it only if the NCL1100 display shows that the RF link failed
(no incoming and/or outgoing packets).
After you run the
tt and yy RF tests, connect the LAN and attempt communication across the
link. By leaving the LAN disconnected until you run all RF tests, you can determine which
side of the link has the problem, LAN or RF.

The screen displays the packets sent and received by the system. These packets are test
packets of approximately 1496 bytes in length. The bar graphs on the lower half of the screen
