2.11 iQUBE Communications Configurations
The following sections describe some of the ways digital or analog output from the
iQUBE
can be connected to
weight indicators.
2.11.1
Copper-Wire Connection to the 920i
A basic configuration of the
iQUBE
is shown in Figure 2-8. A single 6-conductor load cell cable can be used both
to supply 6 VDC power to the
iQUBE
and to exchange serial data with the
920i
indicator. Tap and run connectors
included in the
iQUBE
parts kit are used to tap power from the indicator power supply (see Section 2.12 on
page 14).
NOTE:
Applications using more than two
iQUBE
units must use the
iQUBE
’s optional internal power
supply.

Fiber-Optic and Ethernet Communications
Both fiber-optic and Ethernet communications cards are available for the
iQUBE
. Figure 2-9 shows an
iQUBE
unit with the fiber-optic card and the optional internal power supply installed.
An internal fiber-optic module for the
920i
(see Figure 2-18 on page 16) allows direct fiber-optic communication
between the
iQUBE
and the
920i
. The optional remote fiber-optic interface can also be used to convert digital
data carried on a fiber-optic cable from the
iQUBE
to an analog signal for any weight indicator.
