18 880 Technical/Service Manual
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 that was
assigned to the USB port. Or open the application that is to be used with the 880, such as Revolution, and see
which ports are available.
Configuration of the USB Device Port is done in the USBCOM sub-menu under PORTS in SETUP 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.
Note
Note
If a computer application has an open communications connection through the USB Device Port, and either
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, and printers.
2.6 USB Host
The 880 can host a USB device through the Type A USB connection (J5), see Figure 2-10. Devices that are
supported include USB keyboards and flash drives. See Section 3.2.11 on page 47 for configuration.
For further information see Section 9.2 on page 91.
2.7 Ethernet Communications
The 880 features Ethernet TCP/IP 10Base-T/100Base-TX communication using a standard RJ45 connector (J6 –
see Figure 2-10). 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 880 using the EDP
command set (see Section 6.0 on page 65), 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 Section 3.2.10 on
page 45.
Physical connection to the 880 Ethernet port can be made directly from a PC to the 880 (AdHoc Network), or
through a network router or switch (Infrastructure). The port supports auto-sensing MDI/MDIX cable
configuration, so either straight-through or crossover cables can be used.
The RJ45 Ethernet jack on the 880 houses two LEDs to indicate the status and speed of the connection.
Yellow LED (left) indicates the status of the connection:
• Off for no link
• On for a link
• Blinking if there is activity
Green LED (right) is:
• Off for a 10Base-T connection
• On for a 100Base-TX connection
