5.1 Mounting the Device Server
The NPort 5630-8 can be mounted on a DIN-rail or directly to a wall/panel.
Montaxe en carril DIN:
- Attach the DIN-rail mounting kit to the rear of the NPort 5630-8 using the provided screws.
- Hook the top of the DIN-rail clip onto the DIN-rail.
- Push the bottom of the device towards the DIN-rail until it snaps into place.
Wall/Panel Mounting:
- Attach the wall mounting plates (if included or purchased separately) to the sides of the NPort 5630-8.
- Mark the positions for the screws on the wall or panel using the mounting plates as a template.
- Drill pilot holes and secure the device to the wall/panel using appropriate screws.
5.2 Conexión de alimentación
Connect the 110V power adapter to the power input terminal block on the rear panel. Ensure correct polarity if using a DC power source. The Power LED on the front panel should illuminate once connected.
5.3 Conexión de rede
Connect a standard Ethernet cable (RJ-45) from your network switch or router to the Ethernet port on the rear panel of the NPort 5630-8. The Ethernet Link/Activity LEDs should indicate a successful connection and data activity.
5.4 Conexión de dispositivos en serie
Connect your RS-422/485 serial devices to the RJ-45 8-pin serial ports on the front panel. Refer to the device's pinout diagram for correct wiring. The NPort 5630-8 supports both RS-422 and RS-485 modes, which can be configured via software.
