D-Sub socket, using a PC or notebook and the “BE-Flash” software. You can find the current operating software for the head-end station, the software “BE-Flash” and the current assembly instructions on the website “www.gss.tv”. The modules are designed exclusively for use in the STC 160 head-end station. 3 Installation Caution – Ensure the head end station is mounted so it will not be able to vibrate.
• Open the housing of the head-end station in accordance with the assembly instructions for the STC 160. • Open the locking device 1 in the direction of the arrow (fig. 1). Fig. 1 —> Slots 1 (digital module) and 2 (modulator module) are shown in figure 2. The open slot in between (without a contact strip on the board at the rear wall of the housing) is intended for an add-on module. • Insert the modulator module in grooves A and B (fig.
3.2 Connecting the modulator module ! " Fig. 3 • Using the AV cable C, connect the modulator module to the digital module or to an add-on module if applicable. • After programming, connect the modulator output D to one of the input sockets E on the output collector. • Close the locking device 1 in the direction of the arrow.
4 The control panel at a glance 4.1 Menu items Program the module using the buttons on the head-end station control unit. The menus appear on the two-line display of the control unit. You can use the M button to select the following menu items: – – – – – Modulator settings Modulator output channel Output level Audio setting Storing 4.
5 Programming 5.1 Preparation • Connect the test receiver to the HF output on the modulator module. • Adjust the test receiver to the output channel of the channel strip to be set. • Switch on the modulator if necessary. For each modulator, there is a green LED which indicates if the modulator is switched on. LED – Channel strip “A“ LED – Channel strip “B“ LED – Channel strip “C“ LED – Channel strip “D“ The process of programming the HMM 470 and HMS 470 modules is the same, with one exception.
