4.1 TROUBLESHOOTING OVERVIEW
The Field Programming Software provides help for the user to find problems on individual units within a
network. This program runs (only) from the Integra Setup port.
Here is a list of tests that a user (having network communication problems) can try while using this
software utility:
With user network application's running:
z
Monitor the current network activity by using online diagnostics monitoring feature
z
Gather diagnostics (i.e. local GET Status) from the unit connected to and check that they are within
tolerances
With user network application offline:
z
Check communication link between two units (i.e. Link test)
z
Gather remote diagnostics (i.e. Remote GET Status) from a “suspect” remote unit and check that they are
within tolerances
z
Check RF signal strength of a particular remote unit transmitting a continuous unmodulated test carrier
(i.e. Remote Carrier button)
z
Check RF power output from the connected unit by using the Carrier test button. The RSSI bar graph will
turn to a divided wattmeter (Forward and Reflected power)
z
Check carrier frequency from the unit connected by using the Carrier button and a RF communication
test set
z
Check transmit deviation from the unit connected by using TX Tone button and a RF communication test
set
4.2 INTDIAG
The Field Programming Software is divided into two distinct parts: the Online and Offline diagnostics.
4.2.1 ONLINE DIAGNOSTICS
Online diagnostics may be used for monitoring an operating network with the user’s applications running.
The diagnostics are piggy-backed (carried along with user data transmissions) and do not interfere with
day-to-day operations. Refer to Table 4-1 for diagnostics, descriptions, and tolerances.
Maintaining a registry listing typical diagnostic readings for a network is an effective tool for comparing
test readings and trend monitoring (system history). Variances in the data displayed can alert technicians to
changes in network status. Earlier detection leads to earlier intervention.
