Overview This chapter includes: LED Indicators Housing • DIN Rail • Wall Mount LED Indicators NPort Express’s top panel contains five LED indicators, as described in the following table. LED Name LED Color LED Function Power is on. Power is off, or power error condition exists. orange 10 Mbps Ethernet connection.
Housing DIN Rail For many industrial applications, you will find it convenient to use the DIN Rail attachments, as shown below. STEP 1: Use 2 screws per ear to attach DIN Rail mounts to each of NPort Express’s two ears. ⇒...
Wall Mount For many industrial applications, you will find it convenient to mount NPort Express on the wall, using two screws, as indicated below. STEP 1: Screw two screws, separated by 7.8 cm, into the wall. The heads of the screws should be no greater than 6.5 mm in diameter, and the shafts should be no greater than 3 mm in diameter.
Serial Installation We discuss the following topics: DIP Switch Settings DB25 Female Connector Pinout RS-232 Wiring RS-422 Wiring 4-Wire RS-485 Wiring • Using a DB25 connector • Using the optional Terminal Block Enabling a Termination Resistor • Enabling the Built-In 120 Ω Terminator •...
Switch SW1 controls the function of the serial port (ON, or up, for RS-232 Console connection, and down for Data Communication, such as when NPort Express is connected to your serial device). Note that after changing the setting of SW1, NPort Express will reboot to initialize the new setting. You must wait a few seconds for the green Ready light to blink off and then on again, indicating that the function of the serial port has been changed.

NOTE: The following pinout diagram shows how to use a DB25 (M) to DB25 (F) cable. NOTE: In Ethernet Modem Mode, you need a special cable—shown in the following pinout diagram—to simulate a DCD signal.
RS-422 Wiring Using a DB25 Connector Using the Optional Terminal Block NOTE: Use a flathead screwdriver to tighten the two attachment screws that connect the terminal block to NPort Express.
Using the Optional Terminal Block 4-wire RS-485 Terminal Block Wiring NOTE: Use a flathead screwdriver to tighten the two attachment screws that connect the terminal block to NPort Express. 2-wire RS-485 Terminal Block Wiring NOTE: Use a flathead screwdriver to tighten the two attachment screws that connect the terminal block to NPort Express.
NOTE: When setting up a multidrop network, a daisy-chained network should be used. Construct your device-to-device wiring as indicated in the above figure. Enabling a Termination Resistor For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection.
Enabling the Built-In 120 Ω Terminator To enable NPort Express’s built-in 120 Ω termination resistor, you must short the bottom two pins of jumper 6 (JP6), on DE-211’s circuit board. To do this: 1. Use a screwdriver to remove DE-211’s outer protective case, and then locate JP6, as shown in the figures below.
Enabling a User-Supplied Terminator When using the terminal block, you may install your own external terminator resistor by connecting the ends of the resistor directly to inputs 2 and 3, or by connecting the two ends of the resistor to the wires that emanate from inputs 2 and 3, as shown in the following diagrams.
Ethernet Installation We discuss the following topics: Connecting to the Ethernet Port • Connecting to a Hub or Switch • Connecting to a PC Connecting to the Ethernet Port Connecting to a Hub or Switch For most applications, you will simply plug one end of your Ethernet cable into NPort Express’s 10BaseT port, and the other end into a Hub or Switch that is connected to your network.
Connecting to a PC In some cases, such as when configuring drivers and software, you will find it convenient to hook NPort Express directly to your computer’s Ethernet card. To do this, you will need to use a cross-over Ethernet cable. This type of Ethernet cable is harder to find, although you can make your own cable by referring to the following cable wiring diagram.
Power Connection We discuss the following topics: Using the Power Adapter Using Power Over Serial Power Status Check Using the Power Adapter Take the following steps to connect NPort Express’s power adapter. 1. Plug the power adapter’s DC plug into NPort Express’s DC-IN jack. 2.
Using Power Over Serial Take the following steps to set up NPort Express’s Power over Serial option. IMPORTANT NOTICE You may not use the power adapter and Power Over Serial option at the same time. Using both power options at the same time could cause irreparable damage to your NPort Express unit.
Do NOT force either jumper horizontally, as shown in the diagram. Doing so could cause serious damage to your DE-211, or to the serial device connected to DE-211’s serial port. To use the 5 VDC Power over Serial option, enable jumpers JP2 and JP3, as illustrated in the following diagram.
