1 Config port — This 2.5 mm mini stereo jack serves the same function as the
rear panel Configuration/RS-232 port, but it is easier to access than the rear
port after the switcher has been installed in a rack and cabled. The optional
9-pin D to 2.5 mm stereo mini TRS RS-232 cable (part #70-335-01, shown
below) can be used for this connection. This port has the same protocol as
the rear panel port.
RS-232 protocol :
• 38400 baud
• 1 stop bit
• no parity
• 8 data bits
• no flow control

Both configuration ports require 38400 baud communication. This is a
higher speed than many other Extron products use. The configuration
software (Global Configurator version 2.0 or higher) automatically sets the
connection for the appropriate speed. If using HyperTerminal or a similar
application, make sure the PC or control system connected to these ports is
set for 38400 baud.
Maximum distances from the System 5 IP to the device being controlled may
vary up to 200 feet (61 m). Factors such as cable gauge, baud rates,
environment, and output levels (from the switcher and the device being
controlled) all affect transmission distance. Distances of about 50 feet
(15 m) are typically not a problem. In some cases the System 5 IP may be
capable of transmitting and controlling a given device via RS-232 up to
250 feet (76 m) away, but the RS-232 response levels of that device may be
too low for the System 5 IP to be able to detect.
