Switch Setting for Unknown Cable Lengths

Switch Settings for Known Cable Lengths

When cable lengths are unknown, or the cable is other than the recom- mended cable (Table 2-1.), signals must be compared at the Hub to identify which Equalizer board settings are needed. See page 37.

If the lengths of copper cable exceed those shown in Table 2-2, follow this procedure. See sample calculations page 36. This procedure will set switches SW1, SW2 and SW3 on the Signal Equalizer Board.

Step

Action

1.Measure and record the longest cable run (in Feet) con- nected from a device to any HUB port. The longest cable run does not require a Hub Signal Equalizer board.

2.Calculate the difference between the longest cable length and the length of cable connected to the port you wish to equalize.

3.Locate the difference in feet in the first column (Feet of Ca- ble) of Table 2-2.

4.Identify the correct Selection range in column two of Table 2-4 and set switches SW3, SW2 and SW1.
