Changing Jumper Settings - Epson Equity 386/25 User Manual

Changing Jumper Settings

A jumper's setting is determined by where the jumper is placed.
On the main system board, the jumper can be placed either
between pin 1 and pin 2 (position 1-2) or between pin 2 and
pin 3 (position 2-3), as shown below:
Only pin 1 is labelled on the main system board. Pin 2 is always
the middle pin and pin 3 is on the opposite side from pin 1.
Some jumpers on the main system board are different from the
others. The pin positions for these jumpers are shown below:
On the SPF card, the jumper settings are labelled A and B. The
jumper can be placed either between pin A and the middle pin
(position A) or between pin B and the middle pin (position B).
Otherwise, the jumpers look the same as those on the main
system board.
