3. Select File > Open Port, the
appropriate port (or ports)
from the Open Ports drop list
and Ok.
Note: If you left Port Monitor
open from the previous
subsection, you should
show that the port is
open.
4. Install the loopback plug
Loopback Plugs on Page 13)
onto the port (or ports) that
you want to test.
5. Select Port > Send and Receive
Test Data.
You should see the
alphabet scrolling
across the port. If so,
then the port installed
properly and is
operational.
Note: If you left Port
Monitor
running, it
should show
data sent and
received and
show the
average data
throughput on
the port.
6. Select Port > Send and
Receive Test Data to stop
the scrolling data.
7. Select Port > Loopback
Test.
This is a pass fail test and will take a second or two to complete. Repeat for
each port that needs testing.
The loopback test test the modem control (hardware handshaking) signals. It
only has meaning in RS-232 mode on serial connector interfaces with full RS-
232 signals. If performed under the following conditions, the test will always
fail because full modem control signals are not present:
• RS-422
• RS-485
• RJ11 connectors
8. Close Test Terminal
If both of these tests successfully complete, then the port is operational as
expected.
Note: Do NOT forget to restart the communications application.
