NOTE: Jumper JP17 must be in Position 1-2 (see Table 1 on page 16) if any ports are set for
Type II signaling. This jumper ties all signal battery (SB) signals to battery voltage (–48V).
Jumper JP26 is used to connect all signal grounds (SG) to the chassis ground. When jumper JP26 is in
Position 1-2, the signal ground is connected to the chassis ground. In Position 2-3, it is isolated from the
chassis ground.
