NPort 5600-8-DT User’s Manual Basic Installation
3-4
STEP 1: Connect network, serial device, and power
This step covers the physical installation of the hardware. This step requires the following items:
 NPort 5600-8-DT Series device server
 Power adapter and power cord
 Ethernet cable
 Serial cable with RJ45 or DB9 connector (depending on model)
 Serial device
Connect to Network
After placing the device server in its location, plug one end of the network cable into one of the
device server’s Ethernet ports. Plug the other end of the cable to the network. There are two
Ethernet ports on the NPort 5600-8-DT so you can easily daisy-chain multiple units together.
Attach Serial Device
Use the serial cable to connect your serial device to a device port on the NPort 5600-8-DT. Make
sure that you are familiar with your device’s serial communication settings (e.g., baudrate, stop bit,
etc.). You will need to know these parameters when configuring the device server and drivers.
Adjustable Pull High/Low Resistors for RS-485
Termination resistors may be needed when connecting RS-485 devices to your NPort, in order to
prevent the reflection of serial signals. The device port’s pull high/low resistors must then be set
correctly to prevent signal corruption. DIP switches are located on the bottom of your NPort
5600-8-DT for adjustment of each device port’s pull high/low resistors. You will need to
unscrew the DIP switch cover to access the DIP switches.
The pull high/low resistor values for each device port are set as follows:
1 2 3
SW
Pull High Pull Low Terminator
ON
1 KΩ 1 KΩ 120 Ω
Default
OFF
150 KΩ 150 KΩ
Do not use the 1 KΩ setting when using RS-232. Doing so will degrade the RS-232 signals and
reduce the effective communication distance.
