Figure 2-17 shows the terminal definitions on the analog load cell terminal strip.
Note that when using four-wire load cells, jumpers must be placed between the
+Excitation and +Sense terminals and between the −Excitation and −Sense
terminals.

Note for the standard four-wire cable: If an increase in load results in a
decrease in weight display, reverse the signal wires (+SIG and −SIG).
IDNet Connections
The IND560 terminal supplies 12 V for the new T-Brick type cell of the IDNet base.
Some older types of bases (known as Pik-Brick) required both a 12 V and a 32 V
supply. In order to connect the older type of IDNet base to the IND560, it is
necessary to install an optional kit, which contains a different power supply and an
IDNet power converter board. If connecting one of the older cell bases, install the
new power supply and converter board first, following the instructions in the kit.
When using an IDNet version of the IND560 terminal, the cable connection from
the base is made to a connector (Figure 2-18) on the rear of the housing. The
IDNet bases are supplied with a length of cable and a connector that mates to the
connector on the IND560 terminal. The connector module is shown in Figure 2-19,
and its mounting position in the harsh enclosure in Figure 2-16.
