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.

2.11.2 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.
