Interface S2 To use a 100-ohm matched resistance for data

0transmission, place the jumper over pins 1 and 2.

To do otherwise, place the jumper over jump pins 2 and 3.

See Figure 113.

The jumpers are placed over jump pins 2 and 3, meaning 100-ohm matched resistances are not used.

S1 To use a 100-ohm matched resistance for data receiving, place the jumper over jump pins 1 and 2.

To do otherwise, place the jumper over jump pins 2 and 3.

See Figure 113.

Interface S4 To use a 100-ohm matched resistance for data

1transmission, place the jumper over pins 1 and 2.

To do otherwise, place the jumper over jump pins 2 and 3.

See Figure 113.
