Power Connection

Take the following steps to connect NPort Server Lite’s power adaptor.

1. Connect the power adaptor’s DC plug into NPort Server Lite’s “DC-IN”

jack.

2. Connect the power adaptor to an electrical outlet.

Note that there is no on/off switch. The device server automatically turns on

when plugged into the outlet.

If the device server is working properly, the LCD panel back light will glow

for a few seconds before shutting off, and the green PWR LED will also

light up, indicating that the device server is receiving power. The LCD panel

should look similar to the figure shown in Chapter 1.

Serial Connection

The model of NPort Server Lite that you purchased has either one (models

DE-301/331), two (models DE-302/332), or four (models DE-304/334) male

DB9 serial ports on the front panel. Depending on your serial device and serial

interfaces, there are two connection options:

1. For an RS-232 port, you may use a DB9 to DB9 cable to connect your serial

device to NPort Server Lite. Simply plug one end of the cable into one of the

ports on the front panel of the server, and plug the other end into your serial

device’s serial port.

2. Refer to Appendix A for details of NPort Server Lite’s DB9 pinouts, and

then make your own cable.
