DataNET Hub Signal Equalizer Board
This section sets the switches on the DataNET Hub Signal Equalizer
board. This board is used to equalize the signal amplitude when varying
lengths of copper cable are connected to multiple downlink ports on the
DNH.
Typically the smallest signal on any DNH port is found on the port with
the longest copper cable. Since, Signal Equalizer boards are placed on
ports with signal levels greater than 3 dB the port with the longest cable
does not require a Signal Equalizer board.
This procedure determines the attenuator switch settings. When cable
lengths are unknown, or the cable is other than the recommended cable
(Table 2-1), signals must be compared at the Hub to identify which
Equalizer board settings are needed. See page 37.
