Quick-Start Guide
This document will guide you though a typical
iQUBE 2® installation with RLWS recommended settings. It
assumes an 8-cell truck scale is being used with two iQUBE 2 CPU boards. Refer to Page 4 for iQUBE 2 CPU board
wiring information.
Note
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
iQUBE 2® and the
920i
® using an RS-422 connection.
Note RS-422 is recommended over RS-232 due to the 115,200 baud rate of the iQUBE 2
. RS-232 has a maximum
distance of 10 feet and RS-422 has a maximum distance of 1000 feet at this high baud rate.
2. The below table shows connections needed for RS-422 communications between a host
920i
and the
iQUBE 2 . Two-wire half duplex is available on Port 4 of the
920i
.

3. Ensure
S2
dip switches on the
iQUBE 2 CPU board are set to
485
(1,2 both set to OFF). See the
iQUBE 2
CPU Board illustration in Figure 12 on page 4 for
S2
dip switch location.
Note If a change is made to switch position, cycle power on the iQUBE 2 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).
