2-Series Professional Media Controller Crestron MC2E
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 MC2E.
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. Check the ERR LED indicator on the front panel of the MC2E. If this
LED is illuminated before a program is loaded, unplug the unit and
reapply power after a few seconds. If the LED illuminates again, call
Crestron customer service.
4. 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.
c. Set the baud rate of the MC2E control system to 115200, as
follows:
- Press and release the HW-R button on the unit’s front panel.
- Press and hold the SW-R button for approximately three to
five seconds. The Viewport console should display the
following message:
Viewport Message

- Release the SW-R button.
d. If communication still cannot be established:
- Remove power from the control system.
- Press and hold the SW-R button on the front panel of the
MC2E.
- Reapply power to the control system.
