8. Once all of the control systems have been listed, click Send to Device on
the "IP Table" window to upload the IP table to the UPX-2. The UPX-2 will
reboot and all of the table entries will be listed in black.
CAUTION: At power up or reboot, the touchpanel will cycle through
colors and the Crestron logo screen for approximately 2.5 minutes prior to
displaying the progress bar. This is a normal part of the boot up process. Do
not turn off power to the UPX-2 while it is rebooting. Damage may occur.
NOTE: If a control system is to communicate with the UPX-2 over
TCP/IP, the control system's IP table must have an entry for the UPX-2. The
entry should list the UPX-2's IP ID and the internal gateway IP address
127.0.0.1. For more information, refer to the latest version of the Crestron
e-Control Reference Guide (Doc. 6052).
NOTE: When an IP table is sent to the UPX-2, the UPX-2 will reboot and
the previously loaded IP table will be overwritten.

Troubleshooting Communications

Use the following checklist if communication cannot be established with the UPX-2.
1. Verify that you are using the correct cables. As described previously, an
RS-232 connection requires a null modem serial cable. TCP/IP connection
requires a CAT5 cable with 8-pin RJ-45 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. Remove and reapply power to the UPX-2.
4. If communication still cannot be established, contact Crestron customer
service.
