Downloading QuickPanel Files with a Modem!
This application note describes a method of connecting a QuickPanel to a modem so that files can be
downloaded from a remote location. A diagram showing the configuration is shown below.

HMI-CAB-C49 Cable
On one side of the modem link, a PC is connected to the modem through a serial port. In this example Port
2 is used. A communications program called HyperTerminal is used to establish modem connections. Other
programs such a ProComm Plus may be used to establish modem communications. QuickDesigner Panel
Editor Software, version 3.4, is used to send the project file to the modem.
On the other side of the modem link, a QuickPanel is connected to a modem with a HMI-CAB-C49 cable
and a Null Modem adapter. You may also need a 25-pin to 9-pin adapter since the HMI-CAB-C49 cable has
a 9-pin header. Depending on your modem, you may also need gender changers.
Software Requirements
HyperTerminal is used to connect and configure the modems. This allows changing modem parameters,
and dialing the remote modem, while in the command mode. Once HyperTerminal connects the modems,
the program is disconnected to leave the modems ready for communications.
QuickDesigner uses a program called Courier to communicate with QuickPanels. Courier must be forced to
a fixed baud rate. This is done by editing the COURIER.INI file found in the Quick folder. Change the
AutoBaud setting to 9600. See the sample file below. Note that the Port setting is set to serial port 2.
[Settings]
CourierWindow = 16 63
Port=2
AutoBaud=9600

Running HyperTerminal
• Start the HyperTerminal Program.
• The Connection Description dialog appears. Enter a name and select an icon for the connection.
• When the Phone Number dialog appears, select 'Direct to Com 2' in the Connect using list box.
• When the Com2 Properties dialog box appears, set the parameters as:
9600 Baud
8 Data Bits
No Parity
1 Stop Bit
Flow control=None
Click Ok to enter parameters.
HyperTerminal is now in command mode. If your modem does not have dipswitches, you can enter AT
commands to change the settings of the modem.
Modem Setup
The next step is to setup the modems so that they will respond properly when Courier starts the download
process. The modems used in this application note are from Multi-Tech Systems, Model MT1932ZDX.
These modems are capable of 19.2Kbps. Many other modem vendors can be used in place of the one
listed in this note.
The modems must be set to:
9600 Baud
Auto Answer
DTR Forced High (Ignore DTR)
The modem used in this note required sending command codes to the modem using HyperTerminal. Your
modem may have dipswitches for changing parameters. Here is a list of the commands used in setup.
These commands may be different for your brand of modem.
AT$MB9600
Originate call at 9600 bps.
AT$SB9600
Set serial port to 9600 bps.
AT&S1
Let DSR follow CD.
AT&D0
Modem ignores DTR signal
Dial the remote modem using an AT command such as:
ATDT9,4862807
Once the modems are connected, a message similar to the following one should appear.
CONNECT 9600 LAPM COMPRESSED
Use the Disconnect button on the HyperTerminal tool bar to disconnect HyperTerminal. The modems
should stay connected. If they do not, you must use modem commands to change the communication
parameters.
Run QuickDesigner
Start QuickDesigner. Select the project and click the download button. The file will be sent through Port 2 to
the local modem, then to the remote modem to the QuickPanel. Once the project is loaded, the QuickPanel
should restart with the new project.
