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).
