Welcome to Moxa NPort 4511 Programmable Communication Gateway, a compact palm-sized communications device that allows you to control RS-232/422/485 serial devices over a TCP/IP Ethernet. This chapter is an introduction to NPort 4511 and includes the following sections: Features Product Specifications...
Moreover, PCG’s most important function is to provide something that the typical CG does not have—second stage program development. This gives the developer more options for handling character streams, multipoint connections, and data storage functions. Depending on the kind of program you write, your PCG can be made into different types of Communication Gateway that can be used for different types of applications.
Front/Top/Rear Panel Views The reset button can be used in two different ways, so it requires further explanation. To use the reset button, press continuously for: 3 sec to erase the password After 3 sec, the ready LED will flash on/off every half second. Release the reset button at this time to erase password.
Schematic LED Indicators NPort 4511’s top panel contains three 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 green...
To remove NPort 4511 from the DIN-Rail, simply reverse Steps 2 and 3 above by grasping the bottom of the NPort 4511 unit with both hands, and then using your fingers to pull down slightly on the bottom DIN-Rail mounts. This releases...
6.5 mm in diameter, and the shafts should be no greater than 3 mm in diameter. Do not screw the screws in all the way—leave a space of about 2 mm to allow room for sliding the NPort 4511 unit’s ears between the wall and the screws.
Power Status Check Use the PWR LED on NPort 4511’s top panel to see if it is receiving power. A red light indicates that power is being received. The absence of a light indicates that power is not being received.
For most applications, you will simply plug one end of your Ethernet cable into NPort 4511’s 10/100BaseTX port, and the other end into a Hub or Switch that is connected to your network. In this case, you should use a standard straight-through Ethernet cable, which is readily available from many commercial vendors.
In some cases, such as when configuring NPort 4511 or downloading software, you may find it convenient to connect NPort 4511 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.
Serial Port Installation In this chapter, we give the DB9 Female Connector Pinouts. The following topics are discussed: RS-232 Pinouts and Loopback Tester RS-422/485 Pinouts and RS-422 Loopback Tester Mini Adapter RS-232 Pinouts and Loopback Tester...
In order to make it easier for our customers to attach NPort 4511 to any serial device, a DB9 (male) to DB9 (male) mini null-modem adapter is included as a standard accessory with NPort 4511.
Terminal Block To ease wiring concerns, NPort 4511 now comes with a 9-pin terminal block as a standard accessory, as shown below. The terminal block has a Male DB9 connector that can be used in conjunction with the mini adapter to connect directly to NPort 4511 (note that the terminal block is wired pin-to-pin).
Developing Mode Running Mode DIP Switch Settings The top panel of NPort 4511 contains the following table, which shows how DIP switch 1 (SW1) is used to select NPort 4511’s operation mode. SW1 is located on NPort 4511’s front panel.
Operation Mode Introduction NPort 4511’s two Operation Modes are described in the following subsections. Developing Mode Developing Mode is used when configuring NPort 4511 and when developing and/or downloading a program. The following functions are available when NPort 4511 is in Developing Mode: Run/Stop NPort 4511’s program manually for testing and debugging...
