
Online diagnostics are available using the Online Diagnostics utility without disrupting
network activity

Remote / local diagnostics and statistics / control are available using the Guardian
Offline Diagnostics utility when connected to the Tx module (not Diag Port of T-Base)

The T-Base provides output of Online Diagnostic information which can be processed by
the Guardian Online Diagnostics utility or by a user-supplied network management
program. Contact your sales representative for further information.
2.2.7 NETWORK USING A T-BASE REPEATER
The Network Using a T-Base Repeater has the following characteristics:

Master station and all remotes must be half duplex

Networks described in Section 1.10.2, 1.10.3, or 1.10.5 may be used with a T-Base
repeater

The RTS/CTS delays for each GUARDIAN in the system must be extended as shown in
Table 2-6, RTS/CTS Delays
2.2.8 NETWORK USING A GUARDIAN FOR ONLINE DIAGNOSTICS
The Network Using a Guardian for Online Diagnostics configuration has the following
characteristics:

Master station may be half duplex or simplex

Accumulated online diagnostics for a maximum of 15 stations are available at a
monitoring site (monitoring site must be in range of all remotes)

Online Diagnostics are available in real time at the monitoring site

Remote Offline Diagnostics, statistics, and control are available from the monitoring site
by temporarily disabling network activity (best if using a Master Station Antenna
System)
Online Diagnostics are accumulated in the monitoring Guardian for the last 15 stations
heard. This information may be viewed using the Online Diagnostics utility. For larger
networks, the Guardian can output raw diagnostic data only which may be interpreted for
network management by the Calamp Field Programming Software Online Diagnostics utility
or by a user-supplied software program. Contact your sales representatives for more
information.
2.3 EXTENDING THE COVERAGE AREA WITH A RELAY POINT
The Guardian has a Relay Point feature that allows a unit to relay data from one RF
coverage area to another RF coverage area. When units are spread over two or more
coverage areas, the user must identify the devices forming the backbone between coverage
areas so any unit can talk to any other regardless of their locations. There can be multiple
Relay Points in the system extending the coverage over several hops.
