Operating instructions
Starting the Control Panel Software
To start the TH3 software control panel, it is first necessary to run LecNet Master Pro. If LecNet Master Pro does not
immediately detect the TH3, check to make sure that the LecNet PC cable is connected from the PC’s COM port to
the TH3. Check also that LecNet Master Pro is accessing the correct COM port. Once the TH3 is properly detected,
the TH3 software control panel can be started by choosing Select Device from LecNet Master Pro’s Devices menu.
The Main Window
The main window provides access to most TH3 features, some of which are duplicated on the front panel and wired
remote controls.
The title bar of the main window includes the word “Demonstration” when the software control panel was invoked
directly, as a demonstration of the TH3’s features and control panel operation. When the software control panel is or
has been actively connected to a TH3, as when invoked via LecNet Master Pro, the TH3’s LecNet device address
appears in the title bar. This is especially useful if more than one TH3 is being configured simultaneously.
In the upper right-hand corner of the window is the LecNet Status frame, which indicates whether the serial link to
the TH3 is currently active. A status of on means the TH3 is connected, the control panel is active, and the settings
shown correspond with the TH3’s current configuration. [Note: The connection will be active only when the TH3
software control panel application is active.]
Below the status frame is the Tone Pad, which may be used to generate DTMF dialing tones. If you prefer to type in
a number to be dialed automatically, see the Dial... command under the TH3 menu.
The two largest frames in the main window are the Telephone and Codec frames, which control the TH3’s tele-
phone and codec interfaces. Each frame is equipped with connect and privacy buttons and indicators, which
duplicate the corresponding front panel controls. The privacy indicator does not flash the current privacy mode, as it
does on the front panel, however the current privacy mode is displayed, and may be selected via the radio buttons.
