Connecting to the Network
Connect one end of the Ethernet cable to NPort 5100’s 10/100M Ethernet port and the other end of
the cable to the Ethernet network. NPort 5100 will indicate a valid connection to the Ethernet in
the following ways:
y The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
y The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet
network.
y The Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between NPort 5100 and the serial device. NPort 5100’s serial port
uses the RS-232/422/485 interface to transmit data. The port uses a standard male DB9 pin
assignment. Refer to Appendix A to see the signal definitions for the port.
LED Indicators
NPort 5100 has 3 LED indicators, as described in the following table.
LED Name LED Color LED Function
Steady on: Power is on and NPort 5100 is booting up.
Red
Blinking:
Indicates an IP conflict, or DHCP or BOOTP server
did not respond properly.
Steady on: Power is on and NPort 5100 is functioning normally.
Green
Blinking:
The device server has been located by
Administrator’s Location function.
Ready
Off Power is off, or power error condition exists.
Orange The device is connected to a 10 Mbps Ethernet connection.
Green The device is connected to a 100 Mbps Ethernet connection.
Link
Off Ethernet cable is disconnected, or has a short.
Orange Serial port is receiving data.
Green Serial port is transmitting data.
Tx/Rx
Off No data is being transmitted or received through the serial port.
Adjustable Termination Resistor for RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection
of serial signals. When using termination resistors, it is important to set the pull high/low resistors
correctly so that the electrical signal is not corrupted. Since a particular pull high/low resistor
value cannot fit all environments, the NPort 5150/5130 uses jumpers to set the pull high/low
resistor values for each serial port.
To set a termination resistor to 150 KΩ, make sure both of the assigned jumpers are in the OFF
position. This is the default setting.
To set a termination resistor to 1 KΩ, make sure both of the assigned jumpers are in the ON
position.
