iQUBE2 ® Junction Box/920i
Quick-Start Guide
This document will guide you through a typical iQUBE2 to 920i installation
with the recommended settings. It assumes an 8-cell truck scale is being used
with two iQUBE2 CPU boards.
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 iQUBE2 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
iQUBE2, 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 table below 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.
920i Board
J10 Connector (Port 4)| iQUBE2
J7 Connector
---|---
RS-422 Signal| Pin| Pin| RS-422 Signal
GND| 1| 1| GND1
RS-422 A| 5| 4| RS-485 A
RS-422 B| 6| 5| RS-485 B
3. Ensure S2 dip switches on the iQUBE2 CPU board are set to 485 (1,2 both
set to OFF). See Figure 1 for S2 dip switch location.
NOTE: If a change is made to switch position, cycle power on the iQUBE2
while SW1 is switched to CFG, as the switch position is only read on power-up.
Once power has been re-applied, place the SW1 in the OFF position. Table 2.
J7 (Port 1) Pin Assignments
| J7 Pin | RS-232 Signal | RS-485 2-Wire Signal | RS-485 4-Wire Signal |

| 2 | RxD | — | Rx+ |
| 3 | — | — | Rx – |
| 4 | — | A/+ | Tx+ |
| 5 | TxD | B/- | Tx |
| 6 | — | — | — |

| 2 | iQB | iQB |
| 3 | GND2 | GND2 |
| 4 | GND2 | GND2 |

4. Change Port 4 to iQUBE2 and press Enter to save it.
5. Go back to the SERIAL menu and navigate to the CONFIG parameter under the
SCALES menu.
6. Press the Change Type softkey until Available A/D’s displays in the left
column.GND1 — — A/+ B/- —
7. Press left arrow key to highlight Port 4 – Scale 1.
8. Press the ADD softkey to add it to Associated A/D’s in the right column.
9. Press the Done softkey.
10. Navigate to the SERIAL menu.
11. Change the Port 4 PORTTYPE parameter to 422 (see Figure 3). 12. Navigate
to the CONFIG menu and press the Connect softkey (see Figure 4). The serial
number will show (i.e., 123XX456NONE NONE NONE). If the serial number
does not show, check wiring and dip switches.
Add Secondary Boards to the System
- Under CONFIG, navigate to the BOARDS parameter to select how many boards are being used in the system.
- Press Enter.
- Navigate back to BOARDS parameter and press the Auto Assign softkey. Green lights on the iQUBE2 CPU boards will start blinking on all cells.
- Press and release the setup button (S1) on secondary board #1. This makes cells 5-8 available to the system and registers its serial number with the primary board. The lights on the board will stop blinking.
- Once the secondary unit has been assigned, press the setup button (S1) on the primary board.
- You will see a screen showing the primary board serial number and any assigned secondary board serial numbers.
- Press the Done softkey.
Configure and Add Load Cells
- Under CELLS, set the capacity and confirm the mV/V.
- Ensure all the AVAILABLE Cells are assigned to the correct scale. See Figure 7 for the correct screen layout. NOTE: To turn off the warm up function, set the WARMUP parameter to 0. This allows the unit to skip the warm up period when cycling power.
- Navigate back to the CONFIG parameter.
- Click the Download button.
- Select Configuration Only.
- Download to the iQUBE2 .
- Press the Save and Exit softkey to complete the setup for the iQUBE 2. The scale is ready for calibration.
NOTE: Refer to the iQUBE2 Installation Manual (PN 106113) for calibration
instructions. © Rice Lake Weighing Systems
