Package Checklist
Before installing an NPort 6150/6250 secure device server, verify that the package contains the following items:
- NPort 6150 or NPort 6250
- Power adapter (does not apply to -T models)
- 2 wall-mount ears
- Documentation
- Quick installation guide (this guide)
- Warranty card
Optional Accessories
- DK-35A: DIN-rail mounting kit (35 mm)
- CBL-RJ45M9-150: 8-pin RJ45 to male DB9 cable
- CBL-RJ45M25-150: 8-pin RJ45 to male DB25 cable
NOTE: Please notify your sales representative if any of the above items are missing or damaged.
NOTE: The operating temperature of the power adapter in the box is from 0 to 40°C. If your application is out of this range, please use a power adapter supplied by UL Listed External Power Supply (The power output meets SELV and LPS and rated 12 to 48 VDC; the minimum current is 0.43 A).
Hardware Introduction
NPort 6150
The NPort 6150 unit features a LAN port, RESET button, POWER JACK, and LED indicators (PWR, Ready, Link, P1, P2) on the front. The side view shows serial ports (P1, P2) and a DIP switch.
NPort 6250
The NPort 6250 unit features a LAN port, RESET button, POWER JACK, and LED indicators (PWR, Ready, Link, P1, P2) on the front. The side view shows serial ports (P1, P2), an SD Slot, and a DIP switch.
Reset Button
To load factory defaults, press and hold the Reset Button continuously for 5 seconds using a pointed object like a straightened paper clip or toothpick. The Ready LED will blink on and off. Factory defaults are loaded when the Ready LED stops blinking (approximately 5 seconds). Release the reset button at this point.
LED Indicators
| LED Name | LED Color | LED Function |
|---|---|---|
| PWR | Red | Power is being supplied to the power input. |
| Ready | Red (Steady on) | Power is on and the NPort is booting up. |
| Red (Blinking) | Indicates an IP conflict, or the DHCP or BOOTP server did not respond properly, or a relay output occurred. Check the relay output first. If after resolving the relay output the RDY LED is still blinking, then there is an IP conflict, or the DHCP or BOOTP server did not respond properly. | |
| Ready | Green (Steady on) | Power is on and the NPort is functioning normally. |
| Green (Blinking) | The device server has been located by the Administrator's Location function. | |
| Link | Off | Power is off, or power error condition exists. |
| Orange | 10 Mbps Ethernet connection | |
| Green | 100 Mbps Ethernet connection | |
| Link | Off | Ethernet cable is disconnected, or has a short. |
| Orange | Serial port is receiving data. | |
| P1, P2 | Green | Serial port is transmitting data. |
| Off | No data is being transmitted or received through the serial port. | |
| P1, P2 in-use LED | Green | Serial port was opened by server side software. |
| Off | Serial port has not been opened by server side software. |
Adjustable pull high/low resistor for RS-422/485 (150 KΩ or 1 KΩ)
Open the back door with a screwdriver and use the DIP switch to set the pull high/low resistors. The default is 150 kΩ. You can switch SW1 and SW2 to ON to change the resistors value to 1 kΩ. Do not use the 1 kΩ setting with RS-232 mode, as this will degrade the RS-232 signal and shorten the communication distance. You can also switch SW3 to ON to set the terminal resistor to 120Ω.
NPort 6150 DIP Switch
The DIP switch on the NPort 6150 is used to configure resistors. The diagram shows the switch layout.
NPort 6250 DIP Switch
The DIP switch on the NPort 6250 is used to configure resistors. The diagram shows the switch layout.

| SW | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| High | Low | Term. | x | |
| ON | 1KΩ | 1KΩ | 120Ω | x |
| OFF (Def.) | 150KΩ | 150KΩ | x |
Hardware Installation Procedure
- Connect the 12-48 VDC power adapter to the NPort 6150 and then plug the power adapter into a DC outlet.
- For first-time configuration, use a crossover Ethernet cable to connect the NPort 6150 directly to your computer's Ethernet port. For connecting to a network, use a standard straight-through Ethernet cable to connect to a hub or switch.
- Connect the NPort 6150's serial port to a serial device.
Placement Options
The NPort 6150/6250 device servers have built-in "ears" for attaching the device server to a wall or the inside of a cabinet. It is suggested to use two screws per ear to attach the device servers. The heads of the screws should be less than 6.0 mm in diameter, and the shafts should be less than 3.5 mm in diameter.
The NPort 6150/6250 can also be placed flat on a desktop or other horizontal surface. Additionally, DIN-rail or wall-mount options are available.
Mounting Options Diagram
Diagrams illustrate wall-mount and DIN-rail mounting. Wall-mount requires specific screws (FMS M3 x 4mm), while DIN-rail mounting uses different screws (FTS M3 x 8mm). Screw head and shaft diameter recommendations are provided for wall mounting.
Software Installation Information
For NPort configuration, the default IP address is 192.168.127.254. Log in using the account name 'admin' and password 'moxa' to change settings like IP address or serial parameters.
For software installation, download utilities from Moxa's website:

- Download and install the NPort Windows Driver Manager for Real COM mode.
- Execute NPort Windows Driver Manager to map virtual COM ports on your Windows platform.
- Refer to the DB9 Male pin assignment section to loop back pins 2 and 3 for the RS-232 interface to perform a self-test.
- Use HyperTerminal or a similar program (e.g., Moxa's PComm Lite) to test device functionality.
