you can use a CAT5 crossover cable to connect the two LAN ports directly, without
using a hub.
Once the cable connections are made, open the Crestron Viewport and click Setup |
Communication Settings on the menu to display the "Port Settings" window. Then
click TCP/IP as the connection type. Enter the IP address of the CNX-DVP4 and
click OK. Refer to "Communicating via Ethernet" on page 21 for more information.
To verify communication, click Diagnostics | Establish Communications (Find
Rack). This should display a window that gives the IP address and port number.

Troubleshooting Communications

Use the following checklist if communication cannot be established with the CNX-
DVP4.
1. Verify that you are using the correct cables. As described previously, an
RS-232 connection requires a straight-through serial cable. That is, pin 1 on
one end is connected to pin 1 on the other end. Pin 2 connects to pin 2, etc.
With a TCP/IP connection, you must use a CAT5 cable with 8-pin RJ45
connectors.
2. With a serial connection, verify that the correct COM port on the PC has
been selected. Some computers have more than one COM port; some may
be internal (e.g., for a modem). Consult the manufacturer's documentation
for further information about the COM ports on your PC.
3. With a serial connection, reset the control system as follows:
a. Open Viewport and click Setup | Communications Settings to display
the "Port Settings" window. Choose RS-232 as the connection type.
b. Set the baud rate of the PC to 115200 (use with new .cuz files, version
3.0.17 and higher) or 57600 (use with older .cuz files).
c. Make sure that RTS/CTS is selected and click OK.
d. If communication still cannot be established, reinitialize the unit by
recycling power (the unit takes approximately 25 seconds to reboot). If
the connection is established, the Viewport console should display
some text and the <DVP4> prompt.
e. If communication still cannot be established, contact Crestron
Customer Support.
4. Verify that no other software is using the same COM port.

Compiling and Uploading a Program to the Control System

After you have completed your SIMPL Windows program you must compile and
upload the program to the control system.
To compile the program, simply click the Convert/Compile button
SIMPL Windows toolbar, or select Project | Convert/Compile (you can also press
F12). A status bar will indicate the progress of the compile operation. After the
operation is complete, a window will display information about the program such as
the number and type of signals, and memory usage.
The compiled program will be stored as an SPZ file in the same directory as the
source file. There are several ways to upload an SPZ file to the control system.
1. Immediately after compiling the program you are prompted to transfer the
file to the control system.
2. Click the Transfer button
Send Program window (refer to the following graphic). Click Browse,
