Changing Jumper Settings
There are several sets of jumpers on the X100:

LTC In/ Out (600

or Hi-Z)

Serial Port Rx/Tx Termination (RS-232, RS-422, RS-485)

Analog Audio In/Out (600

or Hi-Z)
All of these jumpers are accessible only after the removal of the top cover, as described on
page 148. Follow the markings on the board to set the pins of the jumpers. A white triangle
on the board indicates
Pin 1 . Ensure that you disconnect both power supplies before
opening the cover.

For serial port Rx/Tx termination ( Figure 2-7 ), jumpers are required only when the module is
set to RS-422 . As shown in the picture, two jumpers are required. When the module is set
to RS-232 or RS-485 , no jumpers are needed.
