For MODBUS® ASCII:
• Send line ends with line feeds
• Echo typed characters locally
• Append line feeds to incoming line ends
• Wrap lines that exceed terminal width
For Frick® protocols (# and $):
• Echo typed characters locally
• Append line feeds to incoming line ends
• Wrap lines that exceed terminal width
Leave everything else on this dialog box unchanged,
then click on [OK] .
The Properties screen will once again be shown. Click
on the [OK] button to proceed.
You will now be back to the main Hyperterminal
communications screen. This screen will be blank. All
communications, both from the computer, and to the
computer (from the Quantum™), will appear on this
screen. Proceed to the Testing Communications sec-
tion.
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
Quantum™ with ID 01 to send a packet of Informa-
tion.)
If the communications is working properly, there
should be an immediate response from the fi rst
Quantum™. The response should look something
(but not necessarily exactly) like #01I000AOMN609.
If this portion of the test has passed, you can try
to communicate to the next (or any Quantum™), by
changing the value that you type into the HyperTer-
minal 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 Quantum™.
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.
