t Configuration port — Connect a controlling device, such as a PC, to this
CONFIG
mini USB B port for control of all FOX II R DP functions (see Remote Control on
page 18 for SIS commands and software control).
This port serves a similar communications function as the rear panel Remote RS-232
port (see item
r
on the previous page), but it is easier to access than the rear port after
the transmitter has been installed and cabled.
NOTE: Both a front panel Configuration port connection and a rear panel Remote
RS-232 port connection can be active at the same time. If commands are sent to
both simultaneously, the processor handles the command it receives first.
Connection Considerations
DisplayPort connections
DisplayPort signals run at a very high frequency and are prone to errors caused by bad
connections or excessive cable length. To avoid the loss of an image or jitter, follow these
guidelines:
• Do not exceed 6.5 feet (2 meters) on the input or buffered loop-through of the
FOX II DP transmitter or the output of the FOX II DP receiver.
• Use only the cable specifically designed and intended for high speed digital signals that
is supplied by Extron. Use of non-DisplayPort cables or modified cables can result in a
missing video output.

NOTES:
• The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
• Longer bare wires can short together.
• Shorter wires are not as secure in the connectors and could be pulled out.
• Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
• The Remote RS-232 port is wired differently than stand-alone Extron RS-232 ports.
