4.0 CONFIGURATIONS

The X120 multiplexers can be connected to the X110 system in two different ways (parallel & serial) and J2, J3,

J4, J5 burg jumpers have to be set differently for each X120 in different configurations.

4.1 Parallel Configuration

Only one X120 is connected to the X110(s) in this configuration and J2, J3, J4 and J5 burg jumpers are

used (installed).

4.2 Serial Configuration

Two to thirty-two X120s can be connected together serially in this configuration. Only J2 & J3 on the

first X120 and J4 & J5 on the last X120 are installed. J2, J3, J4 and J5 should not be installed on any

X120 between first and last.

Figure 2 shows how the X120s are connected serially.
