2.8.1 RSSI by Zone Menu 

(Remotes Only)

This screen displays the strength of RF signals received from the currently associated Access Point. 

Network integrity depends in large part on stable radio signal levels being received at each end of a data 
link. In general, signal levels stronger than –80 dBm will provide reliable communication that includes a 
15 dB fade margin.

If you find there is a poor signal level on one zone, check the section 2.8.3 on page 74 and record the values. 
Then, set the questionable zone to “Skipped” in the Radio Configuration Menu (page 40) and look for an 
improvement in the Packet Statistics error rates. If there is none, return the Zone to “Active.”

RSSI measurements and Wireless Packet Statistics are based on multiple samples over a period of several 
seconds. The average of these measurements will be displayed by the Management System.

Figure 2-59. RSSI by Zone Menu

TIP:

Under normal circumstances, the signal levels in each zone should be within a few decibels of each 

other. If you see one that is significantly lower or higher, it may be a sign of radio frequency interfer-
ence from another signal source on the 900 MHz band. See “Performance Notes” on Page 117 for 
information that can help you minimize radio frequency interference.

2.8.2 Event Log Menu

The transceiver’s microprocessor monitors many operational parameters and logs them. Events are classi-
fied into four levels of importance, which are described in Table 2-5. Some of these events result from a 
condition preventing normal operation of the unit—these are “critical” events. These will cause the unit to 
enter an “alarmed” state and the 

PWR

 LED to blink until the condition is corrected. All events are stored in 

the Event Log that can hold up to 9,000 entries

.
