Updating Firmware
If necessary, you can replace the SCP’s firmware without
changing firmware chips. This procedure must be performed
using a PC on which the Firmware Loader Software has been
installed. The PC’s RS-232 port must be directly cabled to the
SCP’s RS-232 port.
CAUTION
Do not attempt to upload firmware if a System 5 IP
is connected to the SCP with any connections other
than power. The RS-232 cable from the PC must be
connected
directly to the SCP.

Each time that the existing firmware is replaced, the SCP
is reset to the factory default settings.
Follow the directions below.
1. Visit the Extron Web site (www.extron.com) to find the
appropriate firmware file for the model of SCP that you
want to update. Save the new firmware file to your PC,
and write down its filename and save location for later use.
2. Connect a cable between the SCP’s RS-232 port and the
serial (RS-232) port of the PC (see chapter 2).
3. Set DIP switch 4 to the ON position.
4. Power on the SCP. See the
previous caution.

appears, and the Baud button changes to OK.
b. From the pop-up menu, select 9600.
8. Click the OK button that was originally the Baud button
(circled in the figure above). The following window opens,
indicating the current firmware version.
9. Click Upload. You are prompted to select the firmware file
that you downloaded in step 1. Click OK.
