2.5 USB Device Communications – (Port 2)
If using Windows 7 or later, and the PC is connected to the Internet, the operating system may be able to install the
drivers without operator interaction.
Before the USB Device Port can be used, drivers must be installed on the PC.
1. Have power applied to the PC, the indicator and the IO module.
2. Connect a USB cable from the PC to the micro USB connector (J4) on the 882IS IO Module. The PC recognizes a
device has been connected and will attempt to install the drivers needed to make it work. Those drivers can be
downloaded from the Rice Lake Weighing Systems’ website at www.RiceLake.com under downloads.
3. When the individual drivers are installed, a new COM Port designation is assigned for the USB port the 882IS is
connected to on the PC.
For example, if the PC already has two physical RS-232 COM Ports, they most likely are designated COM1 and COM2. When
connecting the indicator to a USB port on the PC, it will be assigned the next available port designation, or in this case, COM3.
When plugging into the same physical USB port on the PC, the port designation will again be COM3. If plugging into another
physical USB port on the PC, it will be assigned the next available designation, in this case COM4.
After the drivers are installed, use Windows Device Manager to determine the COM Port designation which was assigned to the
USB port, or open the application which is used with the 882IS, such as Revolution®, and see which ports are available.
Configuration of the USB Device Port is done in the USB Communications sub-menu under IO MODULE PORTS in
configuration mode.
The port can be configured as either a demand port for EDP commands and printing, or a data streaming port. Other settings
include the termination character(s); enabling echoes and responses; adjust the end-of-line delay; and whether or not the
indicator displays a 'print' message when a print format sends data out the port.
If a computer application has an open communications connection through the USB Device Port, and the physical
cable connection is interrupted, a soft reset is performed on the indicator or power is cycled to the indicator; the
connection in the computer application must be disconnected and reconnected again before it will continue to
communicate with the indicator.
For the USB Device Port, it does not matter what the settings are for Baud, Data Bits, Parity and Stop Bits in the
computer software. The port will communicate in the same way regardless of these settings.
This port is not a host port and is not intended to be connected to other devices such as keyboards, memory sticks
or printers.
2.6 Ethernet Communications
The 882IS IO Module features Ethernet TCP/IP 10Base-T/100Base-TX communication using a standard RJ45 connector (J6 –
see Figure 2-1). It can support two simultaneous connections, one as a server, the other as a client.
Through an Ethernet network, software applications are able to communicate with the 882IS using the EDP command set (see
the 882IS manual), or data can be streamed continuously from the indicator, or printed on demand.
The Ethernet port supports both DHCP and manual configuration of settings such as the IP and subnet. In addition, the TCP
Port number, Primary and Secondary DNS, and the Default Gateway can be configured using the Ethernet sub-menu of the
Ports setup menu. For more information on configuring the Ethernet port see the 882IS manual.
Physical connection to the 882IS IO Module Ethernet port can be made directly from a PC to the 882IS (AdHoc Network), or
through a network router or switch. The port supports auto-sensing MDI/MDIX cable configuration (straight-through or
crossover cables can be used).

2.8 Fiber Optics Assembly
The 882IS IO Module is equipped with a duplex fiber optic port for communicating with an 882IS or 882IS Plus located in the
safe or hazardous area. It provides electrical isolation and eliminates the use of IO barriers commonly used in intrinsically safe
systems. The optical fibers are plastic; no polishing or further preparation is required. See Figure 2-3 on page 5 for the location
of the fiber optic ports in the 882IS IO Module.
The fiber optic connections between the 882IS and 882IS Plus indicator and the 882IS IO Module needs to be cross-
linked. The optical output of the indicator should be attached to the input of the 882IS IO Module, and the indicator’s
input to the module’s output.
Use the following steps for assembling the fiber-optic connectors of the 882IS IO Module:
1. Cut off the ends of the fiber-optic cable with a single-edge razor blade or sharp knife. Try to obtain a precise 90º angle.
2. Insert the fiber cable through the locking nut and into the connector until the core tip seats against the internal micro-
lens.
3. Screw the connector locking nut down to a snug fit, locking the fiber cable in place.
4. Secure duplex fiber-optic cable to wire tie mounting button located on IO Module circuit board (see Figure 2-3 on
page 5) using wire ties included in parts kit.
Figure 2-4. Fiber Optic Connector

3.0 Configuration
Configuration of the external 882IS IO Module is done through the SETUP menu of the attached 882IS indicator acting as the
primary device.
All operating parameters are stored in the host indicator’s EEPROM memory, and can be edited after placing the indicator in
SETUP mode. See the indicator installation or operation manual for instructions on editing configuration parameters.
The 882IS IO Module works as the secondary device of the indicator and will not work as a stand-alone unit. After both the
882IS indicator and 882IS IO Module are powered up, the 882IS attempts to communicate with the IO Module through the fiber
optic port and all necessary working parameters are sent to the 882IS IO Module. All inputs and outputs function as peripherals
of the indicator. Communication must remain constant between the two devices for data to be transferred through the various
ports.
3.1 Updating the IO Module Firmware
The firmware for the 882IS IO Module can be updated using a PC with an RS-232 serial port, and the Revolution Indicator
configuration software package.
* Firmware updates can only be done through the RS-232/RS-422 port. Updates through the USB and Ethernet ports are not supported.
1. Download the new IO Module firmware from www.ricelake.com.
• IO Module firmware file – 156650-880CPUFirmwareVx-xx-xx.S19
2. Connect the RS-232 Port (J3) from the CPU board to a PC.
3. Place a jumper on JP3 while applying power to put the IO Module into BOOT mode.
To access JP3, installed option cards needs to be removed.
4. Remove the jumper from JP3.
5. Start the Revolution software on the PC.
6. Under file, select NEW.
7. Select the 882IS IO Module applicable for the current version of firmware.
8. Under Tools select Options/Communications/AutoDetect.
9. Select the Auto Detect Settings check box and click OK.
10. Under Communications, select Connect. Revolution will establish communications with the IO module.
If it fails to connect, check the connections.
11. Once connected, select Update CPU Firmware or Update Display Firmware in the indicator information menu.
12. Select the file for the Firmware being updated.
The program will proceed to load the new firmware. This may take several minutes, while in progress do not leave the
Revolution window or interrupt the power to the indicator. The progress of the download will be indicated on the Indicator
Information screen.
When the download is complete, the program indicates if it was successful or not.
If it was not successful, turn off the power to the IO module, return to step 3, and try the entire procedure again. If
problems persist, contact Rice Lake Weighing Systems for technical assistance at 1-800-234-9171.
