2. Getting Started

In this chapter, we give instructions o n installing NPort 5x50AI-M12 device servers. Software installation is covered in subsequent chapters.

The following topics are covered in this chapte r:

NPort 5x50AI-M12 Series App earance

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and /or wir ing your NPort

Wiring Caution!

Calculate the maximum possible curre nt in each power wire and com mon wire . Observe all elec trical codes dictating the maximum current allowab If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!

Please take care when handling NPort components generate heat, and consequently the casing may feel hot to the touch. When installed with other components, make sure that there is at least 2 cm clearance on all sides of NPort

in order to allow

proper heat dissipation.

Connecting the Hardware

This section describes how to connect NPort 5x50AI-M12 to serial devices for first tim e testing p urposes. We cover Wiring Requirements, Connecting the Power, Connecting to the Network, Connecting to a

Serial Device, and LED Indicators.

You should observe the following:

• Use separate paths to route wiring for power and devices . If power wir ing and devic e wir ing pa ths must cross, make sure the wires are perpendicular at the intersection point.

NOTE: Do not run s ignal or commu nication wiri ng and power wiring in t he same wir e conduit. T o avoid interfer enc e , wires wi th di ff e re nt signal character istics should be routed sep ara te l y.

• You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separate.

• Where necessary, it is strongly advised that you labe l wir ing to all devices in the system.

Connecting the Power

Connect the power line with the NPort 5x50AI-M12’s M12 connector. If the power is properly supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to a green color.

Connecting to the Network

Connect one end of the Ethernet cable to the NPort 5x50AI-M12’s 10/100M Ethernet port and the other end of the cable to the Ethernet network. If the cable is properly connected, the NPort 5x50AI-M12 will indicate a valid connection to the Ethernet in the following ways:

• The Ethernet LED maintains a solid green color when connecte d to a 100 Mbps Etherne t 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 NPort 5x50AI-M12 and the serial device. Serial data cables are optional accessories for NPort.

LED Indicators

The top panels of all NPort 5x50AI-M12 have four LED indicators , as descr ib ed in the followi ng table.

3. Initial IP Address Configuration

When setting up your NPort 5x50AI-M12 for the fir s t time , the f irst thing you should do is configure the IP address. This chapter introduces the metho ds that c an be used to conf igure the device server’s IP address.

Select one of the initial IP Address configuration methods to configure NP ort 5x50AI-M12’s IP Address. For more details about network settings, see the Network Settings section from Chapter 5, Web

Console Configuration. The following topics are covered in this chapter:

ATTENTION

Consult your network administrato r o n how to reserv e a fixed I P address for your NPort

in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications, you should assign a fixed IP address to your NPort

ATTENTION

In order to use this setup method, both your computer and NPort

connected to the sam e LAN. Or, you may use a cross computer’s Ethernet card. Before exec uting the AR P command,

must be configured

with the factory default IP address

must

be on the same subnet.

Initializing the NPort’s IP Address

1. Determine whether your NPort 5x50AI-M12 needs to use a Static IP or Dynamic IP (either DHCP or BOOTP application).

2. If the NPort 5x50AI-M12 is used in a Static IP environment, you can use NPort Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to conf igur e the new IP address.

3. If the NPort 5x50AI-M12 is used in a Dynamic IP environment, you can use NPort 5x50AI-M12 Administration Suite, Web Console, Telnet Console, or Serial Console to configure NPort 5x50AI-M12 to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.

5x50AI-M12.

Factory Default IP Address

NPort 5x50AI-M12 products are configured with the following default private IP address: Default IP address: 192.168.127.254 (IP addresses of the form 192.168.xxx.xxx are referr ed to as priv ate IP addre s s es, si nc e it is not possible to

directly access a device configured with a private IP address from a public network. For example, you would not be able to ping such a device from an outside Internet connection. NPort 5x50AI-M12 applications that require sending data over a public network, such as the Internet, require setting up the serv er with a va lid p ublic IP address, which can be leased from a local ISP.)

NPort Administration Suite

NPort Administration Suite consists of some useful utility programs that are used to configure and manage your NPort 5x50AI-M12.

See Chapter 5 for de tails o n ho w to i ns tall NP ort A dm inistr atio n Sui te, and how to use thi s s uite o f useful utilities to se t up IP add re s se s and conf i g ure your NPo rt 5x50AI-M12 Series serial device servers.

5x50AI-M12

ARP

You can make use of the ARP (Addres s Resolutio n Protocol) command to set up an IP address for your NPort 5x50AI-M12. The ARP command tells your computer to associate the NPort 5x50AI-M12’s MAC address with the intended IP address. You must then use Telnet to access the NPort 5x50AI-M12, at which point the device server’s IP address will be reconfigured.

Take the following steps to use ARP to configure the IP address:

1. Obtain a valid IP address for your NPort 5x50AI-M12 from your network administrator.

2. Obtain the NPort 5x50AI-M12’s MAC address from the label on its bottom panel.

3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing :

arp –s 192.168.200.100 00-90-E8-xx-xx-xx

This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC address for your NPort 5x50AI-M12. (Be sure to use the actual IP address and MAC address for your NPort 5x50AI-M12.)

4. Next, execute a special Telne t c omma nd by typing :

telnet 192.168.200.100 6000

After issuing this command, a Connect failed message will appear, as shown here. After the NPort reboots, its IP address should be updated to the new address, and you can reconnect us ing either Telnet, Web, or Administrator to check that the update was succe ssf ul.

4. Choosing the Proper Operation Mode

In this chapter, we describe the various NPort 5x50AI-M12 operation modes. The options include an operation mode that uses a driver installed on the host computer, a nd operati o n modes that rely on TCP/I P so cke t programming concepts. Af ter choosing the proper operation mode in this chapter, refer to Chap ter 5 for detailed configuration parameter definitions.

The following topics are covered in this chapter:

Overview

NPort 5x50AI-M12 Serial Device Server s network-enable traditional RS-232/422/485 devices, in which a Serial Device Server is a tiny computer equipped with a CPU, real-time O S , and TCP/IP protocols that can bi-directionally translate data betwee n the seria l and Ethernet formats. Your computer can access, manage, and configure remote facilities and equipment over the Internet from anywhere in the world.

Traditional SCADA and data collection sy s te ms rely on serial ports (RS-232/422/485) to collect data from various kinds of instruments. Since NPor t 5x50AI-M12 Serial Device Servers network-enable ins truments equipped with an RS-232/422/485 communication port, your SCADA and data collection system will be able to access all instruments connected to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site.

NPort 5x50AI-M12 is an external IP-based network device that allows you to expand the number of serial ports for a host computer on demand. As long as your host computer s upports the TCP/IP protocol, you won’t be limited by the host computer’s bus limitation (suc h as ISA or PCI), or lack of drivers for various operating systems.

In addition to providing socket access, NPort 5x50AI-M12 also comes with a Real COM/TTY driver that transmits all serial signals intact. This me a ns that your existing COM/TTY-based softwar e ca n be preserv ed, without needing to invest in additional s of tware.

Three different Socket Modes are available : TCP Server, TCP Client, and UDP Server/Client. The main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer speedier delivery. UDP also allows unicast or multicast of data to only one IP or groups of IP addres ses.

Real COM Mode

One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to continue using RS-232/422/485 serial communications software that was written for pure serial communications applications. The driver intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card. At the other end of the connection, the NPort 5x50AI-M12 accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate ser ia l devic e attached to one of the NPort 5x50AI-M12’s serial ports.

RFC2217 Mode

RFC2217 mode is similar to Real COM mode in that a driver is used to establis h a trans parent connection between a host computer and a serial device by mapping the serial por t on the NPort 5x50AI-M12 to a local COM port on the host computer. RFC2217 defines genera l COM por t contro l op tions based on the Telnet protocol. Third party drivers that suppo r t RFC2 217 are widely available on the Internet and can be used to implement Virtual COM mapping to your NPort 5x50AI-M12 serial port(s).

Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can not only unicast but also multicast data from the serial device to multipl e host computers, and the serial device can also recei from multiple host computers, making this mode ideal for message display applications.

Pair Connection Mode

Pair Connection Mode employs two NPort 5x50AI-M12 units in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5x50AI-M12 is connected from its RS-232 port to the COM port of a PC or other type of computer, such as a hand-held PDA, and the serial device is connected to the RS-232 port of the other NPort 5x50AI-M12. The two NPort 5x50AI-M12 units are then connected to each other with a cross-over Etherne t c able, both ar e connec te d to the same LAN, or in a more advanced setup, they communicate with each other ov er a WAN (i.e., thr o ugh o ne or more ro uter s ). Pair Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the DCD signal) between the two NPort device servers.

Ethernet Modem Mode

Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support TCP/IP Ethernet. By connecting one of NPort 5x50AI-M12’s serial port to the MS-DOS computer’s serial port, it is possible to use legacy software originally des igned to transmit data via modem, but now transmit the data over the Ethernet.

Reverse Telnet Mo d e

Console management is commonly used by connecting to Console/AUX or COM ports of routers, switch es, and UPS units. Rtelnet works the same as RAW mode in that only one TCP port is listened to after booting up. The system then waits for a host on the network to initiate a con nection. The difference is that the RAW mode does not provide the conversion function provide d by T elnet. If the connected devices need to use the CR/LF conversion function when controlling, then users must choose Rtelnet mode.

Disabled Mode

When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

You must assign a valid IP address to the NPort 5x50AI-M12 before it will work in your network environment. Your network system administrator should provide you with an IP address and related settings for your network. The IP address must be unique within the network (otherwise, the NPort 5x50AI-M12 will not have a valid connection to the network). First time users can re fe r to Chapter 3, Initial IP Address Configuration, for more information.

You can choose from four possible IP Configuration modes—Static, DHCP, DHCP/BOOTP, and BOOTP— located under the web console screen’s IP configuration drop-down box.

IP address

Setting Factory Defa ult Necessity

E.g., 192.168.1.1 (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid.)

An IP address is a number assigned to a network device (su ch a s a computer) as a permanent a ddress on t he network. Computers use the IP address to identify and talk to each other over the network. Choose a proper IP address which is unique and valid in your network environment.

Netmask

Setting Factory Defa ult Necessity

E.g., 255.255.255.0 255.255.255.0 Required A subnet mask represents all of the network hosts at one geographic location, in one building, or on the same

local area network. When a packet is sent out over the network, the NPort 5x50AI-M12 will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the same network segment as the NPort 5x50AI-M12, a connection is established directly from the NPort 5x50AI-M12. Otherwise, the connectio n is establ is he d thro ugh the given default gateway.

Gateway

Setting Factory Defa ult Necessity

E.g., 192.168.1.1 None Optional

192.168.127.254 Required

A gateway is a network gateway that acts as an entrance to another network . Us ua lly, the computers that control traffic within the network or at the local I nte r net servic e pro v ide r are gateway nodes. NPort 5x50AI-M12 needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. For correct gateway IP address information, consult the network administrator.

None Optional

When the user wants to visit a particular website, the computer asks a Domain Name System (DNS) server for the website’s correct IP address, and then the computer uses the response to connect to the web server. DNS is the way that Internet domain names are identifie d and translated into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easie r to remember. A DNS server is a host that translates this kind of text-based domain name into the numer ic I P addres s used to es tablis h a TC P/I P connection.

In order to use NPort 5x50AI-M12’s DNS feature, you need to configure the DNS server. Doing so allows NPort 5x50AI-M12 to use a host’s domain name to access the host. NPort 5x50AI-M12 provides DNS server 1 and

DNS server 2 configuration items to configure the IP address of the DNS server. DNS Server 2 is included for use when DNS sever 1 is unavailable.

NPort 5x50AI-M12 plays the role of DNS client, in the sense that the NPort 5x50AI-M12 will actively query the DNS server for the IP address associated with a particular doma in name . NPort 5x50AI-M12 f unc tio ns that support domain name are Time server, Destination IP Address in TCP Client mode, Mail Server, SNMP

Specify the location string for SNMP agents such as the NPort 5x50AI-M12. This string is usually set to the street address where the NPort 5x50AI-M12 is physically located.

None Optional

IP Address Report

When NPort 5x50AI-M12 products are used in a dynamic IP environment, users must spend more time with IP management tasks. For example, if the NPort 5x50AI-M12 works as a server (TCP or UDP), then the host, which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to the NPort 5x50AI-M12, the host must have some way of determining the NPort 5x50AI-M12’s new IP address.

NPort 5x50AI-M12 products help out by periodically reporting their IP address to the IP location server, in case the dynamic IP has changed. The parameters shown below are used to configure the Auto IP report function. There are two ways to develop an “Auto IP report Server” to receive the NPort 5x50AI-M12’s Auto IP report.

1. Use the NPort Administrator’s IP Address Report function.

2. The Auto IP report protoco l can automaticall y re c e ive the Auto IP repo rt on a regular basis, and is also available to help you develop your own software. Refer to Appendix E for the “Auto IP report protocol”.

Setting Factory Defa ult Necessity

1, 2, 3, 4, 5, 6, 7, 8 1 Required Max connection is usually used when the user needs to receive data from different hosts simultaneously. The

factory default is 1. In this case, only one specific host can access this port of the NPort 5x50AI-M12, and the Real COM driver on that host will have full control over the port.

Max Connection 1:

Allows only 1 host’s Real COM driver to open the specific NPort 5x50AI-M12 serial port.

Max Connection 2 to 8:

Allows 2 to 8 host’s Real COM drivers to open the specific NPort 5x50AI-M12 ser ial p ort, at the same time. When multiple hosts’ Real COM driv ers open the serial port at the same time, the COM driver only provides a pure data tunnel without control ability. That is, this serial port parameter will use the firmware’s settings, not depend on your application program (AP).

Application software that is based on the COM driver will receive a dr i ver respon se of “success” when the software uses any of the Win32 API functions. The firmware will only send the data back to the driver on the host.

This parameter defines the time interval during which the NPort 5x50AI-M12 fetches the serial data from its internal buffer. If data is incoming through the serial port, the NPort 5x50AI-M12 stores the data in the internal buffer. The NPor t 5x50AI-M12 transmits data stor ed in the buffer v ia TCP/IP, but only if the internal buffer is full or if the Force transmit time interval reac he s the time spec ifie d unde r Force transmit.

The optimal Force transmit timeout depend s on your app licatio n, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one characte r is

(10 (b its ) / 1200 (bits /s )) * 1000 (ms/s) = 8.3 ms. Therefore, you should set Force transmit timeout to be larger than 8.3 ms, so in this case, it must be greater

than or equal to 10 ms. If the user wants to send a series of characters in the same packet, the serial devic e attached to the N Por t

5x50AI-M12 should send that series of characters during a time interval less than the Force transmit timeout for the NPort 5x50AI-M12, and the total length of data must be less than or equal to the NPort 5x50AI-M12’s internal buffer size. The serial communic ation buffer size for the NPort 5x50AI-M12 is 1 KB per port.

UDP Multicast

A multicast packet is a packet sent by one host to multiple hosts. In multicast mode, hosts that belong to a specific multicast group will recei v e multic as t p ack e ts s e nt to that group. When configuring a host as a multicast receiver over the Internet, routers on the host’ s LAN must be informed. The Internet Group

NPort 5x50AI-M12 Series Web Console Confi guration

Management Protocol (IGMP) is used to communicate gr oup membership information between hosts and routers on a LAN. The NPort 5x50AI-M12 supports IGMP version 2.

To add a network host to the multicast group, input the host’s IP address (e.g ., 239 .1.1.1) in one of the Destination IP addr e ss input boxes, as illustrated above. The NPort will automatically add this host to the multicast group, and the host will start receiving all packets sent by the NPort to this group.

Pair Connection Mode

Pair Connection Mode employs two NPort 5x50AI-M12 device servers in tandem, and can be used to remove the 15-meter distance limitation impo s ed by the RS-232/422 /48 5 inte rface. One NPort 5x50AI-M12 is connected from its RS-232/422/485 port to the COM port of a PC or other type of computer, such as hand-held PDAs that have a serial port, and the serial device is connected to the RS-232/422/485 port of the other NPort 5x50AI-M12. The two NPort 5x50AI-M12 device servers are then connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they communicate with each other over a WAN (i.e., through one or more routers).

Ethernet Modem Mode

Dial-in

The NPort 5x50AI-M12 listens for a TCP/IP connection request from the remote Ethernet modem or host. The NPort 5x50AI-M12’s response depends on the ATS0 value, as outlined below.

ATS0=0 (default):

The NPort 5x50AI-M12 will temporarily accept the TCP connection and then send the “RING” signal out through the serial port. The serial controller must reply with “ATA” within 2.5 seconds to accept the connection request, after which the NPort 5x50AI-M12 enters data mode. If no “ATA” command is received, the NPort 5x50AI-M12 will disconnect after sending three “RING” signals.

≧1:

ATS0

The NPort 5x50AI-M12 will accep t the TC P conne c tion immediately and then send the “CONNECT <baud>“ command to the serial por t, in which <b aud> repres e nts the baudr a te of the NPort 5x50AI-M12’s serial port. After that, the NPort 5x50AI-M12 immediately enters data mode.

Dial-out

The NPort 5x50AI-M12 accepts the AT command “ATD <IP>:<TCP port>“ from the serial port and then requests a TCP connection from the remote Ethernet Modem or PC. This is where <IP> is the IP address of the remote Ethernet modem or PC, and <TCP port> is the TCP port number of the remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, the NPort 5x50AI-M12 will send out the “CONNECT <baud>“ signal via the ser ial por t and then e nte r d ata mode.

Disconnection request from local site

When the NPort 5x50AI-M12s is in data mode, the user can drive the DTR signal to OFF, or send “+++” from the local serial port to the NPort 5x50AI-M12. The NPort 5x50AI-M12 will enter command mode and return “NO CARRIER” via the serial port, and then inp ut “ATH” to shut down the TCP connection after 1 second.

After the TCP connection has been shut down by the remote Ethernet modem or PC, the NPort 5x50AI-M12 will send the “NO CARRIER” signal via the serial port and then return to command mode.

Authentication failure

The user inputs a wrong pass word from the Console or Administrator. When authentication failure occurs, the NPort will immediately send an e -mail or send an SNMP trap.

IP address changed

The user has changed the NPort 5x50AI-M12’s IP address. When the IP address changes, the NPort 5x50AI-M12 will send an e-mail with the new IP address before the NPort 5x50AI-M12 reboots. If the NPort 5x50AI-M12 is unable to send an e-mail message to the mail server within 15 seconds, the NPort 5x50AI-M12 will reboot anyway, and abort the e-mail auto warning.

Password changed

The user has changed the NPort 5x50AI-M12’s password. When the password changes, the NPort 5x50AI-M12 will send an e-mail with the password changed notice before the NPort 5x50AI-M12 reboots. If the NPort 5x50AI-M12 is unable to send an e-mail message to the mail server within 15 seconds, the NPort 5x50AI-M12 will reboot anyway, and abort the e-mail auto warning.

Power failure

We provide two DC power inputs for redundancy. the NPort 5x50AI-M12 Series supports different approaches to warn engineers automatically, such as by email or rel ay output. Users can connect to “Monitor -> Relay Output” from the web console to check what event causes the warning. The relay output will be canceled after the power recovers, or by selecting “acknowledge eve nt” using the web cons o l e or Telnet. When the Relay Output is sending a warning, the Ready LED will flash red until the warning event ceases.

Ethernet link down

NPort 5x50AI-M12 Series provides system maintainers with real-time alarm messages for Ethernet link down. Even when control engineers are out of the control room for an extended per i od of time , they c an still b e informed of the status of devices almost instantaneously when exceptions occur. the NPort 5x50AI-M12 Series supports different methods for warning engineers automatically, such as by email, SNMP trap, and relay output. Users can connect to “Monitor -> Relay” Output from the web console to check which Ethernet port is causing the warning. The relay output will be canceled if the faile d Etherne t link is restored, or by selecting Acknowledge Event from the web console or Telnet. When the Relay Output is issuing a warning, the Ready LED will flash in red until the warning event ceases.

DCD changed

The DCD (Data Carrier Detect) signal has changed, also indicating that the modem connection status has changed. For example, a DCD change to high also means “Connected” between local modem and remote modem. If the DCD signal changes to low, it also means that the connection li ne is down.

When the DCD changes, the NPort 5x50AI-M12 will immediately send an e-mail, send an SNMP trap,or trigger the relay output..

DSR changed

The DSR (Data Set Ready) signal has changed, also indicating that the data communication equipment’s power is off. For example, a DSR change to high also means that the DCE is powered ON. If the DSR signal changes to low, it also means that the DCE is powered off.

When the DSR changes, the NPort 5x50AI-M12 will immediately send an e-mail, send an SNMP trap, or trigger the relay output.

COM Mapping

Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP/7 Real COM drivers. After you install NPort Administration Suite, there are two ways to set up the NPort 5x50AI-M12 serial port as your host’s remote COM port.

The first way is with On-line COM Mapping. On-line COM Mapping will check to make sure that the NPort 5x50AI-M12 is connected correctly to the network and then install the driver on the host computer.

The second way is with Off-line COM Installation, without first connecting the NPort 5x50AI-M12 to the network. Off-line COM Mapping can decrease the s ystem integrator’s effort by solving different field problems. Via off-line installatio n, use rs can first process software installation for the host, and then ins tall the N Po rt 5x50AI-M12 to different fields.

Use the following procedure to map COM ports:

1. On-line COM Mapping: Connect the NPort 5x50AI-M12 to the network  Set the NPort 5x50AI-M12 to the proper IP address  Map COMs to your host  Apply Change.

2. Off-line CO M Mapping: Map COMs to your host  Apply Change  Connect the NPort 5x50AI-M12 to the network  Configure the NPort 5x50AI-M12’s IP address.

6. Select the COM Number. COM ports that are “In use” or “Assigned” will also be indicated in this drop-down list. If you select multiple serial ports or multiple NPort 5x50AI-M12s, remember to check the “Auto Enumerating” function to use the COM No. you select as the first COM No.

7. Hi-performance mode is the default for Tx mode. If the driver comp le te s sending data out to the N Por t 5x50AI-M12, the driver will respond “Tx Em pty” to the program.

Under classical mode, the driver will not notify the user’s program that Tx is completed until all Tx data has been sent out from the NPort 5x50AI-M12; this mode will cause lower throughput. If you want to ensure that all data is sent out before further processing , class ic al mode is recommended.

Enable/Disable Tx/Rx FIFO. If disabled, the NPort 5x50AI-M12 will send one byte each time the Tx FIFO becomes empty; and an Rx interrupt will be generated for each incoming byte. This will r esult in a faster response and lower throughput. If you want to use XON/XOFF flow control, we recommend setting FIFO to Disable.

Fast Flush (only flush local buffer)

• For some applications, the user’s program will use the Win32 “PurgeComm()” function before it reads or writes data. With our design, after the program uses this Pur g e Comm () function, the NPort driver will keep querying the NPort’s firmware several times to make sure there is really no data queued in the NPort firmware buffer, rather than just flushing the local buffer. This kind of design is used because of some special considerations. Howev er, it might take more time (on the order of several hundred milliseconds) than a native COM1, because it needs to work via Ethe r ne t. T hat’s why the native COM ports on the motherboard can work fast with this function call, but the NPort requires much more time. In order to accommodate other applications that require a faster respons e time, the new NPort driver implements a new “Fast Flush” option. Note that by default, this function is disabled.

• To begin with, make sure there are some “PurgeComm()” functions being used in your application program. In this kind of situation, you might find that your NPort exhibits a much poorer operation performance than when using the native COM1 port. Once you have enabled the “Fast Flush” function, you can check to see if there has been an improvement in performance.

• By default, the optional “Fast Flush” function is disabled. If you would like to enable this function, from the “NPort Administrator,” double click the COM ports that are mapped to the NPort, and then select the “Fast Flush” checkbox. You should find that when “Fast Flush” is enabled, the NPort driver will work faster with “PurgeComm().”

Overview

What is IP Serial Library?

IP Serial Library is a Windows library with freque ntly use d ser ial co mma nd se ts and subroutine s . IP Serial Library is designed to reduce the complexity and poor eff ic iency of serial communication over TCP/IP. For example, Telnet can only transfer data, but it can’ t monitor or co nfig ure the seria l line ’ s par am e te rs.

Why Use IP Serial Library?

For programmers who are familiar with serial communication, IP Serial Library provides well-designed function calls that have the same style as Moxa’s PComm Library.

IP Serial Library is amazingly simple and easy to understa nd . By inc luding it in your VB, C, or Delphi programming environment, you can progr a m your own TCP/I P app lic ation with the ability to control serial communication parameters.

NPort 5x50AI-M12 serial device servers use 2 TCP ports for communication between the NPort 5x50AI-M12 and host computer’s Real COM driver. The NPort 5x50AI-M12 uses a data port and command port to provide pure data transfer without decode and encode. Compared to using only one TCP port to control serial communication (such as RFC2217), IP Serial Library uses a command port to communicate with the NPort 5x50AI-M12 in user’s program. IP Serial Library not only runs with excellent efficiency but also runs without any decode or encode problems.

How do I install IP Serial Library?

IP Serial Lib comes with the NPort 5x50AI-M12 Administration Suite. Refer to the IP Serial directory for more detail about the function definitions .
