The Properties screen will once again be shown. Click on
the [OK] button to proceed.
You will now be back to the main Hyperterminal com-
munications screen. This screen will be blank. All commu-
nications, both from the computer, and to the computer
(from the Quantum™), will appear on this screen. Proceed
to the Testing Communications section.
TESTING COMMUNICATIONS
Set the keyboard for CAPS (so that all capital letters will
be typed). Type in the following command: #01I, then
press [ENTER]. (This command will request the Quan-
QUANTUM™ HD COMPRESSOR CONTROL PANEL
COMMUNICATIONS SETUP
tum™ with ID 01 to send a packet of Information.)
If the communications is working properly, there should
be an immediate response from the first Quantum™. The
response should look something (but not necessarily ex-
actly) like #01I000AOMN609.
If this portion of the test has passed, you can try to com-
municate to the next (or any Quantum™), by changing
the value that you type into the HyperTerminal screen as
follows:
Instead of [#01], replace the 01 portion with the ID
that you would like to access. For instance, if you
wanted to talk to a fourth Quantum™ (ID 4), type in
[#04]. This should return a message from that Quan-
tum™.
This has been just a brief description of how to check
your communications and verify that it is working. Greater
detail can be found by consulting tables for each of the
protocols in this manual.
General Notes
Ensure that the Quantum™ communications parameters
are correct. This setup can be found on the Communica-
tions screen. This info must match that of the device that
you are trying to talk to at the other end.
There are two red LED's associated with the Comm port
on the Quantum™ (TX & RX). Ensure that neither of these
LED's are on continuously. If one or the other (or both)
are on constantly, disconnect the Com cable. If the sta-
tus of the LED's does not change, check the wiring con-
nections to the comm port. Ensure that the wiring is not
backwards. If the wiring is correct, power the Quantum™
down, then back up. If either or both of the LED's is still
on, a bad driver chip may be suspected on the Quantum™,
and the board should be replaced.
Once everything has been inspected (cables, jumpers, and
setup), try to develop communications from the leader.
You should see the LED's on the Comm port flickering as
the Quantum™ talks to the leader. If nothing happens, it
