USB Console Port
The O 1006A has an isolated USB mini B console interface using a USB
UART. The UART is USB bus powered, so the O 1006A's status can be
observed at power on. The port settings are 38400 bps, 8 data bits, no parity, 1
stop bit and no flow control.
Windows systems require installation of a FTDI Chip device driver. The system
will prompt to install the driver when the O 1006A is first connected. The
driver can be downloaded automatically from the Internet or manually from
FTDI.
Windows allocates a USB serial CO port when the O 1006A is connected
but it doesn't inform the user as to which port it allocated. This can be
determined by opening the Ports (CO & LPT) tab in the Windows Device
anager.
The O 1006A is shipped with a fixed USB device serial number (12345678).
As a result, the same driver instance is selected by Windows for all units. If
multiple O 1006A units are connected to a USB hub, it may be desirable to
program different serial numbers for each unit. This can be done with the FTDI
Prog application.
A serial terminal program such as HyperTerminal, Tera Term Pro or Putty is
required to connect to the O 1006A console interface. For software uploads,
the program must support the Xmodem protocol. Connect to the O 1006A
using the selected CO port and terminal settings shown above.
See the Management Interface section for information on configuring the
O 1006A.
SFP Selection
Several types of SFP modules are available for different Ethernet optical links.
It is important that the SFP's wave length match the link partner's - 850, 1310,
or 1550 nm. As well, the SFP must be compliant with the port's optical mode
(100BASE-X or 1000BASE-X).
The SFP modules supplied by Luxcom have digital diagnostics which enable
the bar graphs to display received optical power. Detailed diagnostic
information is also available using the console interface. SFPs without digital
diagnostics can be used but the power meters will not work.
The Luxcom 1000-LX SFP transmits into both multimode and singlemode fiber,
but the transmission distance in multimode fiber is greatly reduced because of
bandwidth limitations caused by modal dispersion. odal dispersion varies
greatly from fiber to fiber. The 1000-LX distances in multimode fiber assume
that a mode conditioning patch cord is installed. See the Specifications
section for more information.
The 1000-ZX/ZXE SFP is used for distances up to 100 km. It uses 1550 nm
laser optics. These optics are usually used in matched pairs because the
