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 signif-
icantly lower or higher, it may be a sign of radio frequency inter-
ference from another signal source on the 900 MHz band.
See “Network Performance Notes” on Page 87 for further infor-
mation.
Event Log Menu
The transceiver’s microprocessor monitors many operational parame-
ters and logs them. Events are classified into four levels of importance,
which are described in
Table 3-5 . Some of these events will result from
a condition that prevents the normal 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 8,000 entries
.
Time and Date
The events stored in the Event Log are time-stamped using the time and
date of the locally connected device. Remote units obtain this informa-
tion from the Access Point when they associate with it. The Access Point
obtains the time and date from a Time Server. This server can generally
be provided by a standard Windows PC server SNTP application. In the
absence of the SNTP services, the user must manually enter it at the
Table 3-5. Event Classifications
Level Description/Impact
Informational Normal operating activities
Minor Does not affect unit operation
Major Degraded unit performance but
still capable of operation
Critical Prevents the unit from operating
