Table 127 Set the jumpers on the FIC-4BSE
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.
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 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.
