1 1. Introduction Welcome to Moxa’s NPort Server Lite, an industrial serial device server that greatly enhances the ability of a Windows host (i.e., PC) to control multiple serial devices over a TCP/IP-based Ethernet network.
transmit/receive data functions as well as RTS, CTS, DTR, DSR, and DCD control signals. The NPort Server Lite can be used with your existing applications that support serial communication. A utility program is included that provides simple step-by-step installation instructions and a maintenance wizard that gives you easy access to your asynchronous devices.

2 2. Connecting the Hardware Now that you have been introduced to the NPort Server Lite's features and specifications, it’s time to set up the hardware.
Wall or Cabinet The two mounting plates included with the NPort Server Lite can be used to attach the server to a wall or to the inside of a cabinet. First attach the mounting plates to the bottom of the server (Fig. 2-1a). With the mounting plates installed, you may then attach the server to a wall or cabinet (Fig. 2-1b). Moxa Technologies Co., Ltd. Made in Taiwan Figure 2-1a. Mounting Plates (bottom view) DE-304 RS-232 Device Server 10/100M Ethernet PWR LINK TRAFFIC NP61405 SN:61405 192.168.127.
DIN Rail The NPort Server Lite can be mounted on a standard 35-mm DIN rail. First, attach the DIN rail brackets to the mounting plates (Figs. 2-2a, b). Figure 2-2a. DIN Rail Brackets: Inner Placement Figure 2-2b.
After attaching the brackets, the screw heads should be flush with the mounting plate. The mounting plate can then be attached to the bottom of the unit, with the orientation as shown in Fig. 2-3a or Fig. 2-3b. DIN Rail brackets Made in Taiwan Moxa Technologies Co., Ltd. Figure 2-3a.

A B A B To remove the unit from the rail, simply reverse Steps 1 and 2 above. Use your fingers to pull down on the B end, which should release the bracket from the rail.
Power Connection Instructions for connecting the power adaptor are as follows: 1. Plug the adaptor’s DC plug into the NPort Server Lite’s “DC-IN” jack. 2. Plug the adaptor into an electrical outlet. Note that there is no on/off switch. The NPort Server Lite automatically turns on when plugged into the outlet. When working properly, the LCD screen’s back light will glow for a few seconds and the green PWR LED will also light up, indicating that the NPort Server Lite is receiving power.
3 Using the LCD Control Panel 3. In this chapter, we explain how to use the NPort Server Lite’s LCD control panel. Basic Operation If the unit is working properly, the LCD screen will display a yellow color for a few seconds, after which it turns green. The green PWR LED will also light up, indicating that the server is receiving power. The display will appear like the example below: N P 6 1 4 0 5 1 9 2 . 1 6 8 . S N : 6 1 4 0 1 2 7 .
Detailed Menu Options LCD control panel functions are organized into a hierarchy of menus, with a total of three menu levels. Please refer to Fig. 3-1 for the full menu tree. At the highest level, the MENU button toggles between the default screen, and main menu screen: N P 6 1 4 0 5 S N : 6 1 4 0 5 1 9 2 . 1 6 8 . 1 2 7 . 2 5 4 H M A I N M E N U S E R V S E T T I N G • • • • R ↓ Use the SEL button to advance one level (i.e.

You will encounter two types of configurable fields: The first type involves entering numbers, such as IP addresses, netmasks, etc. For these fields, each digit is modified one at a time. The up button (U) and down button (V) are used to modify the current digit, and the SEL button is used to move to the next digit. When you get to the last digit, press SEL to enter the number into the unit’s memory. The second type of field involves selecting from a set of options.
4 4. Troubleshooting This chapter explains how to solve problems that you may encounter while using the NPort Server Lite. If you still have problems after reading this chapter, contact your dealer or e-mail Moxa for assistance. You may also use the "Problem Report Form" at the end of this manual to notify your dealer that you require prompt technical support. The following topics are covered.
f How do I allow multiple hosts to access the NPort Server Lite? By default, the NPort Server Lite allows access from multiple hosts. This can be controlled using Configurator in the NPort Management Suite. 1. In the Configurator utility, locate the NPort Server Lite on the network and double-click it to view the server’s settings. 2. The Access Control tab is where you can restrict or enable access to the NPort Server Lite. To allow access to all hosts, click “Remove All”.
f Why does Real COM Installer show a question mark (?) above the server icon? This makes it impossible to view the server properties.
The question mark means that your host cannot find the NPort Server Lite. Try the following procedure to resolve this problem: If the host and the NPort Server Lite are in the same location: 1. Verify that the NPort Server Lite’s power adaptor is plugged in and that the unit is receiving power. 2. Verify that the NPort Server Lite’s network cable is plugged in properly. 3. Verify that your computer is properly connected to the network. 4. Double-click the server icon with the question mark.
Programming Problems f Why are the Win32 COMM API functions returning fail codes? Why are the PComm Pro library functions returning the fail code “SIO_WIN32 FAIL”? The fail code for COMM API functions has a different meaning from the fail code for standard COM drivers. You may receive the fail code when the network connected to the NPort Server Lite is unreachable, or if the NPort Server Lite is offline.
