Quick-Start Guide
This document will guide you though a typical iQUBE2® installation with RLWS recommended settings. It
assumes an 8-cell truck scale is being used with two
wiring information.
Load cells or simulators must be connected before following the instructions listed in this document. RS-422 and
RS-485 are used interchangeably. TEDS is not supported.

Configuration using 920i
Establish a Connection
1. Connect the iQUBE2® and the 920i® using an RS-422 connection.
RS-422 is recommended over RS-232 due to the 115,200 baud rate of the iQUBE2. RS-232 has a maximum
distance of 10 feet and RS-422 has a maximum dist
2. The below table shows connections needed for RS-422 communications between a host 920i and the
iQUBE

. Two-wire half duplex is available on Port 4 of the 920i.

3. Ensure S2 dip switches on the iQUBE2 CPU board are set to 485 (1,2 both set to OFF). See the iQUBE
CPU Board illustration in Figure 12 on page 4 for S2 dip switch location.
If a change is made to switch position, cycle power on the iQUBE2 while in Setup mode, as switch position is read
on power-up. Once power has been re-applied,
place SW1 in the OFF position.
4. On the 920i, enter Configuration mode and navigate to the SERIAL menu.
5. Change the PORTTYPE parameter to
422 (see Figure 2).
