Jumper settings & description Default

Interface 0	S2	To use a 100-ohm matched resistance for data
		transmission, place the jumper over pins 1 and 2.
		To do otherwise, place the jumper over jump pins
		2 and 3.
		See Figure 224.
	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 224.
Interface 1	S4	To use a 100-ohm matched resistance for data
		transmission, place the jumper over pins 1 and 2.
		To do otherwise, place the jumper over jump pins
		2 and 3.
		See Figure 224.
	S3	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 224.
Interface 2	S6	To use a 100-ohm matched resistance for data
		transmission, place the jumper over pins 1 and 2.
		To do otherwise, place the jumper over jump pins
		2 and 3.
		See Figure 224.
	S5	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 224.
Interface 3	S8	To use a 100-ohm matched resistance for data
		transmission, place the jumper over pins 1 and 2.
		To do otherwise, place the jumper over jump pins
		2 and 3.
		See Figure 224.
	S7	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 224.

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