MOXA NPort 5200 Series General Device Servers Installation Guide

Step 1: Connect the power adapter to the NPort
5200 using the provided terminal block or DIN-rail power
supply.
Step 2: Connect the NPort 5200 to a network
using a standard Ethernet cable. Use a cross-over cable if
connecting directly to a computer.

Step 3: Connect the NPort 5200’s serial port
to your serial device.
Step 4: Choose between placing the device on a
desktop, mounting it on a wall, or using a DIN-rail mount.

Resetting the Device

To reset the device to factory defaults, press and hold the
Reset button for 5 seconds using a pointed object like a paper
clip. Release the button once the Ready LED stops blinking.

Hardware Introduction
The NPort 5200 device servers are used to control RS-232/422/485 devices. The NPort 5210/5210-T has two 8-pin RJ45 ports, both for the RS-232 interface. The NPort 5230/5230-T has one 10-pin terminal block, with 5 pins used for one RS-232 port, and 5 pins used for one RS-422/485 port. The NPort 5232/5232I/5232-T/5232I-T have one 10pin terminal block, with 5 pins used for one RS-422/485 port, and 5 pins used for another RS-422/485 port.
– 2 –

Use the terminal block for both serial interface and power source with a 28 to 12 AWG (torque value minimum 3.5 lb-in/0.5 N.m, maximum 4.4 lb-in/0.5 N.m) cable with the devices.
Reset Button–Press the Reset button continuously for 5 sec to load factory defaults: Use a pointed object, such as a straightened paper clip or toothpick, to press the reset button. This will cause the Ready LED to blink on and off. The factory defaults will be loaded once the Ready LED stops blinking (after about 5 seconds). At this point, you should release the reset button.

Hardware Installation Procedure

STEP 1: After removing the NPort 5200 from the box, the first thing you should do is connect the power adapter. Connect the 12-30 VDC power line with the NPort 5200’s terminal block, or connect the DIN-rail power supply with the NPort 5200’s terminal block.

STEP 2: Connect the NPort 5200 to a network. Use a standard straightthrough Ethernet cable to connect to a hub or switch. When setting up or testing the NPort 5200, you might find it convenient to connect directly to your computer’s Ethernet port. In this case, use a cross-over Ethernet cable.

STEP 3: Connect the NP ort 5200’s serial port to a serial device.

STEP 4: Placement Options

In addition to placing the NPort 5200 on a desktop or other horizontal surface, you may also make use of the DIN-rail or wall mount options, as illustrated here.

Software Installation Information
For the NPort’s configuration, the default IP address of the NPort is: LAN: Static IP = 192.168.127.254; netmask = 255.255.255.0
You may log in with the password moxa to change any settings to meet your network topology (e.g., IP address) or serial device (e.g., serial parameters). If you would like to apply the Real COM mode to your application, you will need to install the NPort’s driver on your desktop. You may also refer to Moxa’s support website https://www.moxa.com/support/ for the user’s manual, driver, NPort Search Utility, and more.
NOTE For the NPort with RJ45 serial ports, you may refer to the RJ45 Ports pin assignment section to loop back pin 4 and pin 5 for the RS-232 interface to carry out a self test on the device.
