OPERATION- SERIAL PORT I/O INTERFACE

The RS-232 connector on the rear panel is used as a serial port input/output (I/O). This I/O port is used for accessing Ethernet/IP settings, stand alone control capabilities,

system “health” data, firmware version information and other related data.

This interface is not used by the majority of users. But should any system problems arise, the data that may be accessed through this interface can help to track down the

problem. The most common items that might be used are “Display Network Settings” and “Enter Network Set-up”. Many of the remaining selections would typically be

used for troubleshooting purposes along with a QSC technical representative prompting you to access particular menu items so the data can be interpreted.

Connection is made using a null-modem type serial cable between your computer’s serial port and the RS-232 port of the CM16a. Once properly connected, a “dumb-ter-

minal” program (such as Hyper Terminal, a widely used version on most Windows-based PC’s) is started and communication established between the PC and the CM16a.

Following is the basic procedure for starting up Hyper Terminal, naming the connection, specifying the communications settings and an example of “what you should see”

for a text-menu once the communications link has been established. As many different systems and configurations exist on user’s PC’s, the exact appearance of the

screen shots may vary from those shown. Furthermore, if programs other than Hyper Terminal are used, you will need to follow your software’s instructions for establish-

ing communications through your PC’s COM (serial) port.

RS-232 COMMUNICATIONS

1) Connect the RS-232 port of the CM16a to an unused serial port (COM

port) of a PC using a null modem type cable. These cables are different

than the ordinary serial cable.

2) Open the HyperTerminal program. This program is usually started by

clicking the Windows START icon, highlighting PROGRAMS, then

ACCESSORIES and finally, highlighting the Hyper Terminal folder and

clicking on its icon.

The screen-shot below shows a typical icon-view of the Hyper Terminal folder (icons shown for each program in

the folder). If your system was set-up for a list-view, then you will instead see a list of what’s in the folder. Identify

the Hyper Terminal program icon (or name from the list) and click (or double-click as required) to start the program.

In the screen-shot below, the Hyper Terminal icon is the fifth from the left in the row of icons.

3) After starting Hyper Terminal, a Connection Description window will pop-up. It will require that you name your

connection.Enter a name for your new connection (example: CM16a) and click OK to continue.

4) Next, Hyper Terminal needs to know how to “talk” to the CM16a. This selection depends on which port on your

PC the null-modem cable is connected.

Ignore the first three entry fields (phone number information) and go directly to the “Connect using:” entry field and

click on the down arrow for the drop-down menu selection.

Select the appropriate port (COM1 is used in this example) and click OK to continue. The Properties window should

appear next.

5) The Properties window for the selected COM port should now be active. It should be similar in appearance as

the example to the right.

For the Port Settings, use the following information so communication between the CM16a and the computer is in

the same “language”.

Bits per Second9600

Data Bits8

Paritynone

Stop Bits1

Flow ControlXon/Xoff

Once you have set the properties as outlined, click OK to continue.

If all the connections and communications settings are correct, the main Hyper Terminal window will appear next

(see next page).
