DataNET Hub Signal Equalizer Board

Description

Instructions

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.
