Hardware Installation
In the previous section, we introduced the three general operation
modes of NPort Express. This section describes briefly how to con-
nect NPort Express to your serial device, how to hook up the power
cable, and how to connect to the Ethernet.
Serial Connection
NPort Express has one DB9 serial port on the back panel. Depending
on your serial device and serial interfaces, there are two options:
1. You may use a DB9 to DB9 cable to connect your serial device to
NPort Express. Simply plug one end of the cable into the port on
the back panel of NPort Express and plug the other end into your
serial device’s serial port.
2. Refer to Appendix C for details of NPort Express’s DB9 pinouts to
make your own serial interface cable.
Power Connection
You should take the following steps to connect NPort Express’s
power adapter.
1. Connect the power adapter’s DC plug into NPort Express’s DC-IN
jack.
2. Connect the power adapter to an electrical outlet.
Note that there is no on/off switch. The server automatically turns on
when plugged into the outlet, and the red PWR light on NPort Ex-
press’s top panel will glow to indicate that it is receiving power.
Network Connection
There are two ways to use the 10/100BaseT Ethernet jack located on
NPort Express’s front panel (see Fig. 1-2):
1. For most applications using NPort Express, you will simply plug
one end of an Ethernet cable into NPort Express’s 10/100BaseT
jack, and the other end into a hub connected to your network. In
this case, use a regular straight-through Ethernet cable.
2. In some cases, such as when configuring the drivers and software
used with NPort Express, you may connect NPort Express di-
rectly to your computer’s Ethernet card. To do this you will need
