With the built-in RS232 port, it is easy to remote control the Tuner with e.g. a
terminal program. All parameters, that can be selected by keys, can be set. In
addition to that, commands are available to adjust frequencies and channels
numerically. Furthermore, there is a command available to lock and unlock keys.
