NPort 5200A Series
Connecting to the Network
Connect one end of the Ethernet cable to the NPort 5200A's 10/100M Ethernet port and the other end of the
cable to the Ethernet network. The NPort 5200A will indicate a valid connection to the Ethernet in the following
ways:
•
The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•
The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.
•
The Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between the NPort 5200A and the serial device. The NPort 5200A's serial port
uses the RS-232/422/485 interface to transmit data. The port uses a standard male DB9 or terminal block pin
assignment. Refer to Appendix A to see the signal definitions for the port.
LED Indicators
The NPort 5200A has four LED indicators, as described in the following table.

Adjustable Pull High/Low 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 5230A/5250A uses a dip switch to set the pull high/low resistor values for each serial port.
ATTENTION
Do not use the 1 KΩ setting on the NPort 5250A when using the RS-232 interface. Doing so will degrade the
RS-232 signals and shorten the maximum allowed communication distance.
