What is the pin configuration for the DB9 to RJ45 cable required to use the RS232 port or upgrade software?
The rear panel of many Rotel models include an RJ45 connection labeled "Computer I/O". This connection is used for serial RS232 control from control systems such as Crestron or Control4, or to upgrade the internal software in the unit. A special RJ45 to DB9 conversion cable is required in order to connect from a standard DB9 serial connection. Many Rotel products include this cable, or it may also be available through the local Rotel authorized dealer or distributor.
