1.2 Overview
The iQUBE2 is a digital programmable junction box with advanced diagnostic and multi-scale capabilities. A single 4-channel
iQUBE2 board can be configured to support up to four individual scales plus their sum. The modular design allows for the
connection of up to four iQUBE2 circuit boards to define a scale system of up to 16 full bridge analog load cells. An ASCII-based
command set allows the iQUBE2 to be configured and controlled by any programmable host that supports the command set.
1.2.1 Hardware
The CPU board (PN 106390) provides four load cell input channels, four configurable I/O channels, a selectable multi-protocol
communications port (RS-232, 2- or 4-wire RS-485) and an additional port that accepts various Rice Lake option cards (see
Table 1-2 on page 3) for simultaneous communications with multiple hosts.
1.2.2 System Models
The enclosures are available in both fiberglass and stainless steel, with or without a power supply, and in a variety channel
configurations. See Section 1.3 on page 3.
1.2.3 Digital I/O
Each CPU board provides four channels of digital I/O.
Digital inputs can be set to provide indicator functions, including four keys plus cell health and setpoints. The primary CPU
board has four digital inputs/outputs; any secondary CPU boards are used for cell health only.
1.2.4 Configuration
The iQUBE2 is designed for use with any host device capable of sending and receiving ASCII text. A simple communications
program, such as HyperTerminal, can be used to configure the most complex system and monitor all diagnostic capabilities.
In addition, Rice Lake Weighing Systems provides three additional interfaces for configuring and controlling:
• The 1280 Enterprise indicator, using the iQUBE2 configuration screens, using the front panel or Revolution configuration
utility (Revolution module for the 1280 which includes iQUBE2 configuration or an iQUBE2 Revolution module which can
connect directly to the iQUBE2), see Section 3.0 on page 21.
• The 920i Programmable HMI Indicator/Controller, using the 920i menus or the iRev 4 configuration utility, see
Section 4.0 on page 33.
• The Virtui2 PC-based HMI, PC-based indicator and configuration utility, see Section 5.0 on page 44.
Any indicator capable of operation as a serial scale can be configured and used as the indicating element.
1.2.5 Diagnostics
Advanced diagnostic capabilities include:
• Power supply and excitation voltage monitoring
• Load cell connection faults
• Load cell overload, under-load, balanced load, load cell drift, peak-to-peak noise and zero reference errors
Diagnostic information can be included in weight data or monitored on a communications channel separate from weight data.
See Section 7.0 on page 61 for more information about diagnostics.
1.2.6 Transient Protection
Transient protection boards are designed to protect the power supply lines by minimizing the effects of nearby lightening strikes
and other extreme transients.
Transient protection boards are recommended on each end of a power supply run when an external DC supply is used, or on
power supply cables to secondary units where the secondary enclosure runs are longer than 75'.
The transient protection board option (PN 110949) includes a mounting bracket.

2.3 Cable Connections
All models of the iQUBE2 provide cord grips for cabling into the unit, plus a dedicated cord grip for a ground wire. Up to 12 load
cells can be cabled into the iQUBE2 (in large FRP model only); other cord grips allow cabling for serial communications, digital
I/O, and AC power. Install plugs in all unused cord grips to prevent moisture from entering the enclosure.
2.3.1 Cable Grounding
Except for the power cord, all cables routed through the cord grips should be grounded against the indicator enclosure.
1. Install the grounding clamps on grounding studs, using the ground clamp hardware. Do not tighten the screws at this
time.
2. Route the cables through the cord grips and the grounding clamps to determine the cable lengths required to reach
the cable connectors.
3. Mark the cables to remove insulation and shield. See the following information on Stripping Cables.
4. Route stripped cables through the cord grips and grounding clamps.
5. Ensure the shields contact the grounding clamps as shown in Figure 2-1 and Figure 2-2. Tighten the ground clamp
screws.

2.5 Load Cells
Diagnostics may not function properly with load cells having a bridge resistance greater than 700 ohms.
Customers wanting to use load cells with a higher bridge resistance than 700 ohms can consult the Rice Lake
Weighing Systems service department for additional options.
When load cells are wired to iQUBE2 connectors, J1-J4 are assigned by default as channels 1-4 (5-8, 9-12, 13-16 for
secondary units). The graphic representations of the weighing platform shown when configuring the scale, assumes particular
locations for each load cell, based on the connector used. Load cells can be renamed during configuration.
While load cells can be wired to any connector on the iQUBE2 connector board, platforms defined as paired sections (including
most truck scale applications) must correctly associate these pairs to ensure valid calibration and diagnostic functions.
2.5.1 Load Cell Wiring
To attach load cell cables to the CPU board:
1. Route the cables through the cord grips on the load cell connector end of the enclosure.
2. Strip 1/4'' of insulation from the ends of the load cell wires.
3. Install wires into the connectors as shown in Table 2-2.
4. Use cable ties and mounts to secure the load cell cables to the enclosure, when connections are complete.
Pins 5 and 6 provide connections for load cells that provide TEDS (Transducer Electronic Data Sheet)
information.
Do not connect sense wires to the TD terminals.
For load cells with a resistance greater than 2,200 Ohms, a high precision 2k Ohm resistor should be placed between
the EXC+ and EXC- pins of the load cell connection to maintain correct operation of the Cell Connect diagnostic.
Precision resistor properties: Temperature Coefficient ±10 ppm/°C; Tolerance ±1%

2.6 Serial Communications
Serial communications between the iQUBE2 and host or peripheral devices is provided by two ports.
• Port 1 – provides onboard RS-232 (full-duplex) or RS-485 (full- or half-duplex) communications on connector J7. S2 on
the CPU board is a pair of switches that are used to select the required setting
• Port 2 – uses an option card installed in connector J9 to expand the communication capabilities of the iQUBE2. Available
option cards support fiber-optic, wired and wireless Ethernet, USB, and RS-232/RS-485 communications
To attach serial communications cables, route the cable through the cord grip and wire to the connector on the CPU board. Use
cable ties to secure serial cables to the inside of the enclosure.
2.6.1 Port 1 Communications
Table 2-3 shows the pin assignments for Port 1 connector J7.
The switches are only read on power-up; if switch settings are changed, cycle power to the iQUBE2 before
attempting to communicate using Port 1.
RS-485/422 Connections to Host Indicators
See Section 4.0 on page 33 for connection to the 920i.
See Section 3.0 on page 21 for connection to the 1280.
Selecting Communication Type for Port 1
To select communication protocols on Port 1:
1. Remove power from the iQUBE2.
2. Place the S2 switches in the proper position for the communication type to be used. See Table 2-4.
3. Place SW1 in the CFG position.
4. Apply power to the iQUBE2.
5. Place SW1 in the OFF position.

2.6.2 Communications Option Cards
Table 2-5 lists communications option cards available for the iQUBE2. Communications option cards are installed in the J9
connector of the primary CPU board for the iQUBE2 system. All option cards use Port 3 except for wireless Ethernet, which
uses Port 2.
2.6.3 Communications Cable Distance Limitations
The maximum cable lengths that can be used for the communication types depend on a number of factors.
• Output impedance of the transmitter
• Electrical noise in the environment
• Cable capacity, wire gauge, termination, shielding and baud rates.
Use the distances in Table 2-6 as a general guide for communication cabling.
Data rate decreases with distance. See Table 2-7.
Ethernet port is not suitable for connection to circuits used outside the building and is subject to lightning or power
faults.

2.7 Digital I/O
Each iQUBE2 board provides four channels of digital I/O.
Digital inputs can be set to provide many indicator functions, including four keys (Zero, Tare, Units, Mode) plus cell health, and
setpoints. See Table 6-10 on page 59 for a complete listing. The four digital inputs/outputs on the primary CPU are
configurable; any secondary CPU board’s I/O are used for cell health only.
The fastest I/O reaction times are achieved when the iQUBE2 controls its own free-running setpoints using its own local I/O (2
milliseconds). If preacts are required, the host device should be used as the controller for its own I/O.
Rice Lake does not recommend the use of iQUBE2 (local) I/O with host device controlled setpoints using the preact functions
as variances in the reaction time in serially controlled I/O can dramatically affect the preact algorithm.
Cell Health
The iQUBE2 CPU board provides bi-color cell status LEDs next to each load cell connector. These LEDs indicate the status of
connected load cells.
Digital inputs are active/low (0 VDC), inactive/high (5 VDC). Digital I/O are active/low if the CPU board’s LED color is green.
Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink, rather than source,
switching current.
Each output is a normally open collector circuit, capable of sinking 25 mA when active. Digital outputs are wired to switch relays
when the digital output is active (low, 0 VDC) with reference to a 5 VDC supply.
Table 2-9 shows the pin assignments for connector J5.

2.8 Primary/Secondary Wiring and Configuration
An iQUBE2 system can consist of up to four boards, with up to four load cell channels wired to each board. Standard
enclosures can accommodate one or two boards; large enclosures allow up to three boards. For control of a multi-board
system, one board is assigned as the primary unit and the J12 connector (M/S port) is used to provide communication between
the primary and up to three secondary units.
Figure 2-5 shows the primary-to-secondary wiring for multiple iQUBE2 boards. Successive secondary units are wired in parallel
(A to A, B to B, GND to GND) to the J12 connector of each iQUBE2 board.
The M/S port provides RS-485 communications at approximately 450 KBPS. This port is reserved for communication
between iQUBE2 boards. No other devices should be connected to this port.
Figure 2-5. Primary-to-Secondary Communications Wiring
The cell numbering for secondary units follows the sequence of the load cell connector designations, with
connectors J1–J4 of the first secondary unit assigned cells 5–8, as shown in Table 2-11

2.8.1 Assigning Board Addresses
Once the primary and secondary unit ports are wired (Figure 2-4 on page 9), their addresses must be assigned. There are two
ways to assign the secondary board addresses in an iQUBE2 system: manual entry or automatic, push-button assignment.
2.8.2 Manual Entry
Manual address assignments are done by manually entering the secondary board IDs and the desired addresses in the Virtui2
Configuration Utility or the indicator being used.
2.8.3 Start Auto Assign Procedure
For the 920i - The MS.AUTO algorithm can be started via software using a terminal program and sending the MS.AUTO
command to the iQUBE2 or by pressing the Auto Assign softkey in the Boards menu of the 920i. Additionally, the following
hardware implementation of the MS.AUTO algorithm can be used when no HMI is connected or the HMI is not easily
accessible.
For the 1280 - The MS.AUTO algorithm can be started via software using a terminal program and sending the MS.AUTO
command to the iQUBE2 or by pressing the Start Auto Assign Procedure in the Boards Assignment menu of the 1280.
Additionally, the following hardware implementation of the MS.AUTO algorithm can be used when no HMI is connected or the
HMI is not easily accessible.
1. Place the desired primary iQUBE2into setup mode by setting SW1 to CFG.
2. Remove power to the primary iQUBE2 by unplugging the J6 connector from the CPU board.
3. Press and hold S1 and return power to the CPU board by reconnecting J6.
4. Once J6 is reconnected, release S1 to begin the MS.AUTO algorithm.
The green status LEDs for each channel blinks on all iQUBE2 CPU boards in the system (primary and secondary).
MS.AUTO places all iQUBE2 boards in the system in a suspended state in which they are unresponsive to any
commands. Once started, MS.AUTO can only be terminated by pressing the S1 switch, waiting for the algorithm to
time out (approximately five minutes) or powering down the units.
2.8.4 Push-Button Address Assignment
Once MS.AUTO has been started (all boards’ channel status LEDs are blinking), the addresses for the secondary boards can
be assigned.
If MS.AUTO has been set on the iQUBE2 and it will be connected to a host device, upload the data from the iQUBE2 to
the host device. Ensure the master and secondary are configured, using the serial port menu go into the iQUBE2
screen and connect to the iQUBE2. Select upload to get data to host device.
1. Press and release the S1 button on the unit to be assigned as Secondary #1 (not the primary board). This registers its
ID with the primary unit which then assigns it an address. The channel status LEDs on this board stop blinking. The
status LEDs for all other boards in the system continue to blink.
2. Repeat Step 1 for Secondary Unit #2 and #3, as necessary.
3. Press and release the S1 button on the primary iQUBE2 once all secondary units have been assigned.
4. If using the hardware implementation method described above, store the assigned addresses into non-volatile
memory by setting SW1 to OFF on the primary iQUBE2.
For accessibility, in enclosures that contain more than one iQUBE2 board, the top board is typically the primary.
2.8.5 Manual Assignment with Virtui2
Primary/secondary assignment is performed within the Device Configuration section of the Virtui2 Configuration Utility. Refer to
Section 5.0 on page 44.
