Loopback Tests
Loopback Tests
Loopback tests validate the internal wiring of each port, and the port
RS232/RS422 circuitry.
There are two Loopback Tests:
- All Ports Loopback
- Single Port Loopback
While Single Port Loopback Tests can be performed in Multi User Mode,
the All Ports Loopback Test must be done in Single User Mode.
Loopback Tests require the use of the RS232 Loopback Connector Plug.
For the EasyConnection Dual Interface Module, you will also require
the RS422 Loopback Connector Plug. This is part of the Dual Interface
Module bit.
The Loopback Test displays the current line status of all ports on
the EasyConnection panel. When you plug the Loopback Connector
Plug into a port, the status of every signal on that port should change.
This indicates a successful Loopback Test for that port. If some
signals do not change, or a diagnostic error message displays for the
port, the Loopback Test has failed for that port.
Note: Indicator Lights which are "asserted' are green or display
as +. Indicator Lights which are "not asserted' are red or display as
-.
All Ports Loopback Test
To activate the All Ports Loopback Test:
Step 1.
Boot the system in Single User Mode.
Step 2.
Highlight Select on the Main Menu and press <Enter>.
Step 3.
Highlight the panel to be tested and press <Enter>.
Step 4.
Highlight Analyze on the panel Configuration Menu and press <Enter>.
Step 5.
Highlight Loopback and press <Enter>.
Step 6.
Plug the Loopback Connector Plug into a port on the panel. If
all Indicator Lights (RS232/RS42 signals) are "asserted' the test
on that port is successful.
Step 7.
Repeat step (6) on all ports on the panel.
Step 8.
If any test is unsuccessful, that port may be faulty.
Note: This test sends characters out all ports on the panel
under test, and should be used with no devices connected.
Single Port Loopback Test
To activate the Single Port Loopback Test:
Step 1.
Highlight Select on the Main Menu and press <Enter>.
Step 2.
Highlight the panel containing the port for testing and press
<Enter>.
Step 3.
Select the port to be tested and press <Enter>.
Step 4.
Highlight Analyze on the Port Configuration Menu, press <Enter>.
Step 5.
Highlight Loopback and press <Enter>.
Step 6.
Working '/' appears in the top right corner of the screen until
the Single Port Loopback test diagram displays.
Step 7.
Plug the Loopback Connector Plug into the port being tested. A successful
test shows all Indicator Lights (RS232/RS42 signals) "asserted'.
Step 8.
If the test is unsuccessful, the port may be faulty.
It is possible for a Stallion port to sustain damage to the driver
chips and still pass the loopback diagnostic test. Stallion have developed
a 'loaded' loopback tester to determine whether a port has been damaged
to the point where it cannot sustain sufficient voltage under a given
load. This type of damage is not covered by the warranty.
