2.3 Connection Procedure
(3) When powering the 8910 from the supplied AC adapter and
powering connecting devices from a DC source (or when
powering the 8910 from DC and connecting devices from AC)
Before making other connections to the 8910, first connect the ground
of the 8910 to the grounds of the devices to be connected. Refer to the
following alternatives regarding common ground connection methods.
(a) Connect the grounds of devices running on DC power to the AC
adapter’s ground.
(b) Connect pin 3 (CAN_GND) of the 9713-01 CAN Cable to the
ground of the device to be connected.
Note: In method (b) above, because of wire length and CAN cable
wiring conditions, some potential difference may remain
between grounding points, so we recommend (a) as the
preferred method.
