2.2.1 NETio Backplane Communication
When a NETio Unit consists of a Base Module and Expansion Modules,
as shown in
Figure 2-1
, all Expansion Modules should be connected to
the Base Module using the backplane and power connector on the side
of the modules. The configuration process is easiest if all modules are
attached together via the backplane.
2.2.2 Measure & Connect DC Power
Input power applied to NETio must be within 6–30 volts DC and be
capable of continuously providing a minimum of 11 Watts. (Typical
current consumption is: 350mA @13.8 Vdc for NETio Base Modules.
Each module has screw terminations for power and I/O signals. Termi-
nations 1 and 2 are for power as shown in
Figure 2-2
. Strip the wire
leads to 6 mm (0.25"). Be sure to observe proper polarity with the posi-
tive lead (
+
) on the left and negative on the right.
NOTE:
When multiple modules are connected via the backplane
connector, all modules are powered via the Base Module only.
Do not connect power to each of the Expansion Modules.
