2.4 Description
FM signals can be supplied to the cable network over the FM amplifier CGA 225.
This involves sending the FM signals over an IEC socket to the FM amplifier. To
eliminate interference, up to 6 different input frequencies can be lowered with
tuneable traps. The amplified, selected HF signals are supplied to the cable
network over the HF output of the FM amplifier.
If the FM amplifier is not detected by the head-end station you can update the
head-end station’s operating software over the head-end station’s 9-pin Sub-D
socket, by using a PC or notebook and the “
BE-Flash
” software.
