1.3 Description

The iServer is a stand alone Ethernet Server designed to connect devices with serial
interfaces to the Ethernet network using the TCP/IP protocol. It contains Ethernet and
RS-232/485/422 interfaces.

The standard features include:

• Use standard Web Browser , TCP connection, HTTPGET DOS program or Telnet
Simulation, for network connectivity.

• Install via RS-232/485/422 serial port connection.

•

Transfer data from RS-232/485/422 serial interface to TCP/IP using built-in socket server.

• Use a standard home page or customize Web page for OEM applications.

This device can be purchased as a stand alone DIN Rail mounted unit, or
as a bench/wall mount unit.

The following example illustrates how you can hookup the devices with serial interface
on the network using the iServer:

2.2 DIP Switches

1 To change the IP address, gateway address,

and subnet mask from the serial port
2 To change to default factory settings
3 To enable/disable DHCP
4 To enable/disable Terminal Server function

The iServer is shipped with all
DIP switches in "OFF" position

To set the iServer to factory default settings, slide DIP switch #2 to ON position. Power the
iServer on and wait about 10 seconds until the iServer fully boots up. Set the DIP switch
#2 back to OFF position (it does not matter if the iServer is powered ON or OFF, just make
sure that the DIP switch is set to OFF, otherwise, every time the unit is power-cycled the
factory settings will take over. See Section 4.6 for setting the iServer to factory default
using the firmware (over the LAN).

To enable the DHCP, besides using DIP switch #3, set the iServer’s IP address to 0.0.0.0.
An iServer with IP address of 0.0.0.0 will request an IP address, gateway address, and
subnet mask from the DHCP server over the Ethernet.

2.4 Serial Communication Interfaces

Two communication interfaces are supported in the standard iServer: RS232 and
RS485. In addition, the serial port can also be provided with TTL logic on request.
These standards define the electrical characteristics of a communication network. The
RS485 port of the iServer is fully compatible to use with RS485 and RS422 instruments.
The RS485 is an extended version of the RS422 communication standard which
increases the allowable number of devices from 10 to 32 by improving the electrical
characteristics.

• The RS232 standard (point-to-point) allows a single device to be connected to an
iServer. The iServer operates with full-duplex RS232 using eight wires: Rx-receive,
Tx-transmit, DTR, DSR, DCD, CTS, RTS and common ground wires. RS232 cable
length is limited to 50 feet.

• The RS485 standard (multi-point) allows one or more devices (multi-dropped) to be
connected to the iServer using a two-wire connection (half-duplex) +Rx/+Tx and
–Rx/-Tx. Use of RS485 communications allows up to 31 devices to connect to the
iServer with cable length up to 4000 feet long.

Although the RS485 is commonly referred to as a "two wire" connection, the
iServer also provides a ground/return shield connection to use as a common
connection for EMI noise protection.

• The TTL standard (point-to-point) allows a single device to be connected to an
iServer. The iServer operates with full-duplex TTL using three wires:Rx-receive,
Tx-transmit, and common ground wires.

Table 2.2 shows the differences between RS232 and RS485 communication interfaces.

Table 2.2

Data Transmission Characteristics RS232 RS485

Transmission Mode Single ended Differential
Electrical connections 8 wire 2 wire
Drivers per line 1 driver 32 drivers
Receivers per line 1 receiver 32 receiver
Maximum cable length 50 ft (15 meters) 4000 ft (1200 meters)

Changing between RS232 and RS485 interfaces, as well as modifying the
other parameters is possible through the iServer firmware using its home Web
page or Telnet connection (see Part 4 for details).

Table 2.4 shows the connector locations for Tx and Rx

signals for the TTL interface. The ground and +5Vdc can be
connected according to Table 2.3.

2.4.3 Wiring RS485 Interface

RS485 interface uses a two-wire communication system (one for transmitting and one for
receiving) plus a common wire to connect to the shield of the cable. It is recommended
to use a shielded cable with one twisted pair.

Use of twisted pair and shield will significantly improve noise immunity.

Figure 2.5 shows multi-point, half-duplex RS485 interface connections for the iServer.

Figure 2.5 Multi-point, Half-Duplex RS485 Wiring

Value of the termination resistor is not critical and depends on the cable
impedance.

2.5 Network Communication Interfaces

2.5.1 10Base-T RJ-45 Pinout

The 10BASE-T Ethernet network (RJ-45) system is used in the iServer for network
connectivity. The 10 Mbps twisted-pair Ethernet system operates over two pairs of wires.
One pair is used for receiving data signals and the other pair is used for transmitting data
signals. This means that four pins of the eight-pin connector are used.

Figure 2.6 RJ45 Pinout

2.5.2 10Base-T Crossover Wiring

When connecting the iServer directly to the computer, the transmit data pins of the
computer should be wired to the receive data pins of the iServer, and vice versa. The
10Base-T crossover cable with pin connection assignments are shown on Figure 2.7.

Figure 2.7 10Base-T Crossover Cable Wiring

Use straight through cable for connecting the iServer to an Ethernet hub. The
ports on the hub are already crossed.

PART 3

NETWORK CONFIGURATION

3.1 Network Protocols

The iServer can be connected to the network using standard TCP/IP protocols.
It also supports ARP, HTTP (WEB server), DHCP, DNS and Telnet protocols.

3.2 Ethernet (MAC) Address

MAC (Media Access Control) address is your computer's unique hardware number.
When you're connected to the LAN from your computer, a correspondence table relates
your IP address to your computer's physical (MAC) address. The MAC address can be
found on the label of your device and contains 6 bytes (12 characters) of hexadecimal
numbers XX:XX:XX:XX:XX:XX hex

For example: 0A:0C:3D:0B:0A:0B

There is an duplicate MAC address label included with your unit.

3.3 DHCP

DHCP, Dynamic Host Configuration Protocol enables individual computers or devices to
extract their IP configurations from a server (DHCP server). If the DHCP is enabled on
your iServer, as soon as the iServer is connected to the network, there is an exchange of
information between DHCP server and the iServer. During this process the IP address,
the Gateway address, and the Subnet Mask will be assigned to the iServer by the DHCP
server. Note that the DHCP server must be correctly configured to make such assignment.

The DHCP can also be enabled if the iServer’s IP address is set to 0.0.0.0.
If fixed or static IP address is desired, the DHCP must be disabled. The iServer is

shipped with DHCP disabled (factory default). The DHCP can be enabled by setting the
DIP switch # 3 to the “ON” position (refer to Figure 3.2).

Figure 3.2 DIP Switch on the Bottom Side of iServer

3.4 DNS

DNS, Domain Name System enables individual computers and devices to be recognized
over a network based on a specific name instead of an IP address. For example, instead
of having to use http://192.168.1.200 (IP address), you would use only http://eis03ec or
any eight character name stored as Host Name under Access Control page in the
iServer Home Page. The default DNS name for an iServer is "eis" followed by the last
four digits of the MAC address of that particular iServer.

1. It is very important to communicate with the network administrator in order to
understand the DHCP and its existing configurations on the host server,
before enabling the DHCP on the iServer.

2. The iServers are shipped with a default static IP address of

192.168.1.200 and Subnet Mask of 255.255.255.0.

3. On Novell networks or Windows 2000 where the DCHP is an updated
function of DNS this feature may be beneficial since a particular name can be
assigned eliminating the need for the IP address, as described in Section 3.4.

3.5 IP Address

Every active device connected to the TCP/IP network must have a unique IP address.
This IP address is used to build a connection to the iServer’s serial port. Every computer
using TCP/IP should have a unique 32-bit address. It is divided into two portions, the
network ID and the host ID. For instance, every computer on the same network uses the
same network ID. At the same time, all of them have a different host ID. For more details
about the IP address see Appendix B.

3.5.1 Default IP Address

The iServer is shipped with a default IP address set to 192.168.1.200 and Subnet Mask
of 255.255.255.0. If you are going to use a Web browser or Telnet program to access
the iServer using its default IP address, make sure that the PC from which you’re
establishing the connection has an IP address that is in the same range as the iServer’s
IP address (192.168.1.x, where x can be any number from 1 to 254.

Your PC’s IP address cannot be the same as the iServer’s IP address).

You also need to make sure that your PC’s Subnet Mask is 255.255.255.0. This is a
good way to access the iServer over the network and make any configuration changes
needed. If the factory default address is already in use on your network, use an Ethernet
crossover cable between your computer and the iServer and modify the IP address or
any other settings within the iServer.

3.6 Port Number

All TCP connections are defined by the IP address and a port number. A port number is
an internal address that provides an interface between an application running on your
computer and the network through the TCP/IP protocol.

There are three default TCP port (socket) numbers assigned to the iServer:

1. Port (socket) number 1000 when using HTTPGET program.

2. Port (socket) number 2000 when trying to access your serial device connected to
the serial port of the iServer.

3. Port (socket) number 2002 when trying to access the iServer itself for reading or
changing the settings. This can be done using Telnet application.

Example: C:\>Telnet 192.168.1.200 2002

PART 4

OPERATIONS

This iServer can be used and configured in several ways, depending on user’s
preference and network setup. It can be used in Telnet simulation mode where it
emmulates serial communication operation over a network cable or directly from a Web
browser, like Netscape or Internet Explorer. It can also be configured using NEWPORT’s
iCONNECT Configuration Software.

If DHCP and DNS servers are used, the connection is very simple, you do not need to
worry about IP address, MAC address, or network conflicts, all of these issues are solved
for you by your network DHCP and DNS server. All that is left for you to do, is to enable
DHCP on the iServer (see Section 2.2) and use a straight network cable to connect the
iServer to a hub and power it up.

If DHCP is not the preferred method, you can configure your PC’s network connection with
an IP address of 192.168.1.x that is in the same range as the iServer’s default IP address
(192.168.1.200) and connect to the iServer using a cross-over network cable between your
PC’s network port and the iServer. After you’re done with configuring the iServer, you can
always set your PC back to its original settings.

On your computer, from the MS-DOS Prompt window type "ping 192.168.1.200” and
press Enter. If DHCP and DNS servers are used type “ping eisxxxx”, where xxxx are the
last four digits of the iServer’s MAC address, located on the back of the device. You should
get a reply as shown in Figure 4.1.

Figure 4.1 Pinging eis03ec MS-DOS Prompt

This proves that the connection is proper and you can get into configuration or run mode
using the Telnet or Web browser.

4.2.1 Device Setup

From the iServer Home Page, this option allows the users to add up to eight devices (in
RS485 mode) and the iServer will send the entered commands out and will receive the
responses from those devices. The responses can be seen by clicking on the “Take
Readings” button.

Since only one device can be connected in an RS232 connection, there should be only
one device entered in the “Device Setup” page.

By clicking on the numbers from 1 to 8, the parameters for each device can be defined.

Figure 4.6 Device Setup

In the “Device Parameters” page the “Device Name” and the “Response Unit” fields are
simply text fields and each can take up to eight alphanumeric characters. The “Device
Command” field is where the actual command is typed. The iServer will send this
command to the serial device as soon as the “Take Reading” button is clicked.

Figure 4.7 Device Parameters

In RS485 connection, the
RS485 node number must

4.2.4 Configuration

This section describes the "Configuration" page of the iServers’s Web interface.
To get into the Configuration page, the user will be prompted with a Login Password. The

default Login password is 12345678 and is changeable, if desired.
When connecting your serial device to the iServer, the Serial Communications parameters

(baud rate, data bit, parity, and stop bit) must be the same on both, the iServer and your
serial device.

Figure 4.11 Configuration

4.2.4.A Serial Communication
Baud Rate: The serial port speed can be set from 300 to115,200 bits/s (default is 9600 bits/s.)
Data Bit: Options are 7 or 8 (default is 8 bits.)
Parity: Options are Odd, Even, and None (default is None.)
Stop Bits: Options are 1 and 2 bits (default is 1 bit.)

4.2.4.A Serial Communication (continued)
Transceiver: The iServer’s DB9 serial port can either be set to RS-232 or two-wire RS-

485 (default is RS-232.)
Modbus/TCP: A widely used protocol mainly in industrial automation applications with

default TCP port number of 502 (see Local Port field). The options are Enable and Disable.
If enabled, the Modbus/TCP is the only protocol driven by the iServer on its LAN port. If
disabled, the TCP/IP is the only protocol driven by the iServer on its LAN port (default is
disable).

End Character: When the defined Hex character is received by the iServer on its serial
port, the iServer will forward the buffered serial data to the Ethernet. The default value is
00, which forces the iServer to forward the data to the Ethernet as it receives the data on
its serial port (this means that the iServer requires NO “end character” to forward the
data).

Forward End Char: If enabled, the iServer will send the End Character out to the
Ethernet as part of the data. If disabled, the iServer will not count the End Character as
part of the data and will drop it (default is enabled.)

Timeout: In RS232 connection, if the iServer does not receive any more serial data
within the given time value, the iServer will forward the buffered serial data to the
Ethernet. For example, if the Timeout is set to 200 ms, the iServer will send out the
buffered serial data to the LAN, if it does not receive any more data on its serial port for a
period of 200 ms.

In RS485 connection, the Timeout value is used to switch between serial transmit and
receive mode. Since the iServer supports 2-wire RS485, it needs to either transmit or
receive serial data and the Timeout value determines the time interval for each. The
range can be from 0 to 9999 ms (default is 0 ms).

Serial Port Password: The Telnet connection to the iServer’s serial port (default port

2000) can be password protected if this option is enabled (default is disable). If enabled,
the actual password can be placed in the next field.

4.2.4.B Terminal Server
TCP/UDP: The iServer supports TCP and UDP protocol (default is TCP). If UDP is

selected, it can be configured either for Broadcast UDP or Directed UDP. In case of
Broadcast UDP, the iServer will transmit the serial data to every node on the network.
This can be accomplished if the Remote IP Address is set to 255.255.255.255.

The Broadcast UDP is a practical solution when one device needs to communicate with
multiple PC’s or devices over the network (one-to-many connection). In the case of
directed UDP, the iServer will transmit the serial data to a specific node on the network
(one-to-one connection). This can be accomplished if the Remote IP Address is set to
the IP address of that specific node.

Server Type: In most cases the iServer will be acting as a Slave device. Slave option is
chosen when a network host needs to connect to the serial port of the iServer (default is
Slave).

Number of Connections: The range is from 0 to 5. If 0 is selected, the Terminal Server
feature is disabled. This means that no network connection can be made to the serial
port of the iServer. If 1 is selected, only one network connection can be made to the
iServer’s serial port. Any number more than 1 would allow the network hosts to monitor
(read only) the traffic on the iServer’s serial port simultaneously, but only one network
host would be allowed to read and write (default is 5).

18

4.2.4B Terminal Server (continued)
Local Port: This is the port or socket number for the iServer’s serial port. Any number

between 500 and 9999 can be defined with the exceptions of 1000 and 2002 which are
already used by the iServer for other purposes (default is 2000.) Port number 502 is the
default socket number for Modbus/TCP protocol. If Modbus/TCP is enabled in the
iServer, it’s then suggested to use 502 for the Local Port unless your host software that
supports Modbus/TCP indicates otherwise.

If your application software is IP enabled, it means that it can open a connection
to a node on the network (i.e. iServer with the attached serial device) with an IP
address and a port number. In some cases the application software may not
allow you to specify the iServer’s port number (it only allows you to enter the
iServer’s IP address). In these cases, you should put 23 in the Local Port field of
the iServer. By doing this, the iServer will forward connections that are made to
its Ethernet port directly to its serial port.

Connection Control: Some serial devices accept connections or disconnect
connections based on certain signal conditions. For example, a serial device may accept
a connection only if the incoming DTR signal (connected to device’s DSR or DCD) is
high or low. In this case, when the iServer receives the TCP connection, before it
forwards it to its serial port, it must raise its DTR (DTR+) or to lower its DTR (DTR-). The
iServer is capable of doing this with any of the hardware or modem control signals (DTR,
DSR, DCD, RTS, and CTS).

"Reconnect" is one of the options in the Connection Control menu. This option
can be used in the Serial Tunneling described in Section 4.10. If the connection
in Serial Tunneling is broken due to network problems, power failure, etc., the
Reconnect option will try to get the connection back on line every whatever the
"Connection Timeout" is set to. For Example, if the Connection Timeout is set to
1000 x10 ms or 10 seconds, then every 10 seconds the iServer attempts to
reconnect and reestablish the serial tunnel to the other network node.

Device No.: Refer to Section 4.2.1

4.2.4.C Remote Access (Tunneling)
Remote Access: This option needs to be enabled when Serial Tunneling is configured.

The Serial Tunneling is explained in detail in Section 4.10.

Changes made in the iServer’s Configuration page can be saved permanently
by pressing the Save button. Pressing the Reset button will set all the fields
back to their default values.

4.2.5 Configure Access Control

This section describes the "Access Control" page of the iServers’s Web interface. This
page allows the users to set up the network and security parameters of the iServer.

To get into the Access Control page, the user will be prompted with an Administrator
Password. The default Admin password is 00000000 and is changeable, if desired.

At the initial entrance to the “Access Control” page you will be prompted for the Login
Password (see Figure 4.5) prior to an Administrator Password.

Figure 4.12 Access Control

Login Password: This allows users to access and modify all of the iServer Home Page

menu items, except “Access Control”, which requires an Administrator password. The
default Login password is 12345678. This password can be up to 16 alpha-numeric
case-sensitive characters.

If there is no Login Password assigned (blank box) the iServer will not require a
password to access and modify iServer Home page menu items.

Admin (administrator) Password: This allows users to access and modify the "Access
Control" page. The default password is 00000000. This password can be up to 16 alpha­numeric case-sensitive characters.

If there is no Administrator Password assigned (blank box) the iServer will not require
password to access and modify "Access Control" page.

Web Server: This will allow or disallow accessing the iServer’s Web server using an
Internet browser (default is enabled.)

Host Name: Refer to Section 3.4, DNS.

MAC Address: This is also called Hardware address or Ethernet address, which is

assigned to the iServer at production. The MAC (Media Access Control) address is the
iServer’s unique hardware number and is not changeable.

IP Address: The IP (Internet Protocol) address is a 32-bit number that identifies each
sender or receiver of information that is sent in packets across the Ethernet or the
Internet. The iServer’s default IP address is 192.168.1.200. The iServer’s IP address
should be changed to fit user’s networking environment. Consult with your IT department
for obtaining an IP address.

The DHCP will be enabled in the iServer if its IP address is set to 0.0.0.0. The
DHCP can also be enabled by setting the dip switch number 3 to ON position.

Gateway Address: A gateway is a network point that acts as an entrance to another
network. A gateway is often associated with a router, which knows where to direct a
given packet of data that arrives at the gateway. If the iServer is sending packets to
another network node that is not on the same network on which the iServer is connected,
a gateway address needs to be given to the iServer. The gateway address should be the
IP address of the router connected to the same LAN to which the iServer is connected.
The iServer’s default gateway address is 0.0.0.0. Consult with your IT department for
obtaining a gateway address.

Subnet Mask: It’s a 32-bit number that is used to determine which part of the IP address
is the network portion and which part is the host portion. The iServer’s default subnet
mask is 255.255.255.0. Consult with your IT department for obtaining a subnet mask.

Changes made in the iServer’s Access Control page can be saved permanently
by pressing the Save button and power recycling the iServer (press Power
Recycle button). Pressing the Reset button will set all the fields back to their
default values.

22

4.3 Setting a New IP Address using the Serial Port

Once you know the IP address that you need to put on your iServer you can use a serial
connection (Terminal Emulation) to assign the IP address to the iServer.

Setting the IP address over the serial port requires a crossed-over (null modem) serial
cable and Hyper Terminal or any terminal emulation program. When all the connections
are done, change the DIP switch #1 to "ON" position and press the Reset button or
reset the power on the iServer. The Hyper Terminal screen will acknowledge your
connection by asking for the command.

DIP switch # 1 shown
in “ON” position

Figure 4.13 DIP Switch #1

Type "IP=xxx.xxx.xxx.xxx" and press Enter.
The screen will acknowledge that your command was executed.
You can also set the iServer’s gateway and subnet mask by typing

"GW=xxx.xxx.xxx.xxx" and "SM=xxx.xxx.xxx.xxx", respectively.
Then type q and press Enter
You can now change the DIP switch #1 back to the “OFF” position and reset the power

on the iServer.

Figure 4.14 Setting the IP address via the Serial Port

You can access the iServer’s complete settings by connecting the iServer’s serial
port to your PC’s COM port using a null-modem cable. Bring up a terminal
emulation program (i.e. HyperTerminal) and make sure the right COM port is
selected and the serial communications settings (baud rate, character bit, stop bit,
and parity) match the iServer’s serial port. Power the iServer on and press the
Enter key within 5 seconds of powering the iServer. The iServer will then transmit
its complete configurations to the PC.

You need to make sure to setup the
following parameters on your terminal
emulation program (i.e. Hyper Terminal)

Baud Rate - 9600 b/s

4.3 Setting a New IP Address using the Serial Port (continued)

All that is left for you to do, is to use a straight/normal network cable to connect the
iServer to an Ethernet hub and power it up. Then you can go to your computer that is
connected to the same network and from the MS-DOS-Prompt window type "ping

192.168.1.70" where 192.168.1.70 is the new IP address for the iServer.

4.4 Setting a New IP Address over the Network

Besides using the iCONNECT software, you may use the iServer’s default IP address to
access it and assign a new IP address to it.

The iServer is shipped with a default IP address of 192.168.1.200 and Subnet Mask of

255.255.255.0. You can configure your PC’s Network connection with an IP address that
is in the same range as the iServer’s IP address (192.168.1.x) and connect to the iServer
using a crossover network cable between your PC and the iServer.

With this completed, you can go to the DOS-Prompt and ping 192.168.1.200. If you
receive responses back (Figure 4.15), you can go to the Web browser and type in
http://192.168.1.200 and it will take you to the iServer’s Home Page.

Select

,

button, you’ll be asked for the password. First default LOGIN
password is "12345678" and the ADMINISTRATOR password is "00000000", then you
should be on the Access Control page were you can simply type in the desired Static IP
address, and click Save.

For more details about the “Access Control” page refer to Section 4.2.5.

Figure 4.16 Access Control

For the IP address to take effect the iServer needs to be turned OFF/ON or
press the Reset button.

Once all of this is done, you can connect the iServer to an Ethernet hub using a straight

4.5 Terminal Server Function

It is used to provide dedicated connectivity between computers and serial devices
through the iServer over the Ethernet, without dedicated wiring. The typical Internet
protocol consists of a request and a reply to that request. In this situation the server is
the Host that generates the request and receives the reply from the device, that gets
forwarded to the appropriate party on the network. But there are specific applications
where a message is generated by the device, and the server is simply passing the data
to the appropriate party on the network, in this situation the server acts as Slave.
Examples are the Attendance Time Clocks, Bar Code Readers, remote Displays or
Electronic signboards, etc.

For the iServer to pass the data back and forth between its Serial and Ethernet
interfaces, the Terminal Server option needs to be configured as follows (Figure 4.17):

1. Set the Server Type to Slave

2. Set the Number of Connections to 1 or higher.

3. Set the Local Port number to any number from 599 - 9999, except numbers
1000 and 2002.

4. Press the Save button to store the new settings.

From your application software on the host machine, you can now point to the IP address
of the iServer and the assigned port number to establish a TCP connection to your serial
device connected to the serial port of the iServer.

4.6 Terminal Emulation

On this page you can send and receive data to and from the serial device. Simply, type
the command in the white area and as you type the characters, the characters will be
transmitted out from the serial port of the iServer. If you want to send the whole
command as a word, simple paste the word in the same area. This is an excellent tool to
retrieve data from the serial port without any special software, only a web browser.

4.7 Telnet Setup

Telnet stands for Telecommunications Network, is a protocol that provides a way for
users (or clients) to connect to computers (or servers) on a network, whether in the next
building or across the other side of the world.

You can open a Telnet session using other terminal emulation programs like Tera Term
Pro (downloadable from the internet), which is a free software for MS-Windows. It
supports VT100 emulation, Telnet connection and serial port connection.

Once the Telnet mechanism is decided we can open a session by simply typing the IP
address of the iServer, and setting the Port on 2002 for logging into the iServer
Configuration page or 2000 for accessing the serial device connected to the iServer’s
serial port.

4.8 HTTPGET Program

You can setup and read the information from the iServer by using the HTTPGET
program. The following program can be used to read data from the embedded server
firmware by using TCP port 1000. The command string sends to this TCP port, then it
reads back the response from the same port. Whatever you write to the port goes to the
serial port unmodified. Any response from the serial port can be read back from the
same socket.

The Httpget.exe file is used to setup and read information from the iServer. This file will
be automatically installed when you install the Mail Notifier software available on our
website and CD.

Example to use the "Httpget" program:

1. Create a directory C:\iServer\Httpget.

2. Copy httpget.exe and readme_features.doc files to this directory.

3. Make sure that you are in this directory and then enter the following test program:

C:\iServer\Httpget\httpget –r –S "*01X01\r" 192.168.1.200:1000

where:
"-r –S" are switches before the command string
"01" is device address (in hex format) for RS485 communication interface (skip for

RS232)
"X01" read measurement data value (iSeries protocol)
"\r" calls out a CR
"192.168.1.200" is an IP address
"1000" is a local port number

Respond:

01X01074.3

where:
"01X01" is Echo command
"074.3" is a display reading of the 4-digit device

In the example above the 4-digit iSeries controller has been connected to the
serial communication port of iServer.

4.9 ARP Protocol

ARP is the Internet layer protocol responsible for determining the MAC (hardware)
address that corresponds to a particular IP address. The ARP command allows the user
to view the current contents of the ARP cache of the local computer (residing on the
same network) or remote computer (residing on the different network) through a router.
Microsoft includes the ARP.EXE utility for viewing and modifying the ARP cache with its
Windows products. The following ARP commands can be used to view cache entries:

• arp –a ➞ Use this command to view all ARP cache entries.

• arp –a plus IP address ➞ Use this command to view ARP cache entries associated

with one particular interface on a network with multiple adapters.

• arp –g ➞ Same as arp –a.

• arp –N ➞ Use this command to display ARP entries for specific network interface.

• arp – s plus IP address plus Physical address ➞ Use this command to manually add

a permanent static entry to the ARP cache.

• arp –d ➞ Use this command to manually delete a static entry.

Ping the destination computer using IP address first before using the arp -a
command.

The following window shows examples of arp commands and responses.

• Your computer has an IP address of 192.168.1.118

• The destination computer has an IP address of 192.168.1.96

4.10 Remote Access (Tunneling)

To "tunnel", in this context, is to transmit data between two points through a private
conduit on a shared or public network. The network could be an Ethernet LAN, a WAN,
or the Internet. The iServer allows for a connection between a serial device and a PC, or
between two serial devices, using an existing network rather than dedicated wiring.

Today, there are number of serial devices like sensors, gauges, PLCs, card readers,
security alarms, barcode scanners, data loggers, video cameras, ATM machines, time &
attendance terminals, medical lab equipments, electronic signboards, and many others
that are directly connected to PCs via their serial ports.

These devices can be attached to shared Ethernet networks (TCP/IP protocol) and get
accessed, controlled, and managed remotely using the iServer products. Any two
iServer’s can talk to each other over the Ethernet LAN, WAN, and Internet using TCP/IP
protocol. Therefore, the connected serial devices to iServer’s can also communicate with
each other back and forth over these networks. This characteristic is called Tunneling
and it’s illustrated in Figures 4.23.

Figure 4.23 Serial Tunneling

In order to use this Tunneling feature, some settings are required within the local and
remote iServer’s.

4.10.1 Remote iServer

It’s recommended to configure the Remote iServer and have it up and running before the
Local iServer is configured.

1. A static IP address must be assigned to the Remote iServer. This means that the DHCP
must remain disabled. Refer to the DHCP section of the user’s manual for details.

2. Use a browser to access the Remote iServer’s WEB page. Simply type the iServer’s IP
address at the browser’s URL location (i.e. 192.168.1.50) followed by an Enter key.
You should then see the iServer’s main WEB page.

3. Click on the Update button.

4. Click on Configuration, you will be prompted with a Password (default is 12345678).

5. On the Configuration page, under Serial Communication section, make sure the
parameters such as Baud Rate, Data Bits, Parity, Stop Bits, Flow Control, etc. match
with your attached serial device.

6. Make sure to set the End Character (Hex) to 00 and the Timeout to 0.

7. Under Terminal Server section, set Number of Connections to 1 or higher.

8. Click on Save button for the changes to take place.

Make sure that the serial cable and communication settings between the iServer and the
serial device are valid.

4.10.2 Local iServer

1. An IP address should be assigned to the iServer dynamically or statically (recommended).

2. Use a browser to access the Local iServer’s WEB page. Simply type the iServer’s IP
address at the browser’s URL location (i.e. 192.168.1.49) followed by an Enter key.
You should then see the iServer’s main WEB page.

3. Click on the Update button.

4. Click on Configuration, you will be prompted with a Password (default is 12345678).

5. On the Configuration page, under Serial Communication section, make sure the
parameters such as Baud Rate, Data Bits, Parity, Stop Bits, Flow Control, etc. match
with your attached serial device and its application software.

6. Make sure to set the End Character (Hex) to 00 and the Timeout to 0.

7. Under Terminal Server section, set Number of Connections to 0.

8. Under Remote Access section, set the Remote Access to enable, Enter the Remote
IP address (would be the IP address of the remote iServer, 192.168.1.50), and use the
default Remote Port number 2000.

9. Set Connection Control to Reconnect and set the Connection Timeout to a desired value.

The Reconnect option is used in Serial Tunneling and it applies only to the Local
iServer. If the tunneling connection between the two iServers goes down due to
network problems, power failure, etc., the Reconnect option will enable the Local
iServer to reconnect with the Remote iServer based on the specified time interval in
the Connection Timeout. For example, based on a timeout of 1000 x 10 ms (10
seconds), the Local iServer will continually attempt to reconnect and re-establish the
tunnel with the Remote iServer every 10 seconds.

10. Click on Save button for the changes to take place.

11. Initialize the serial device application software to establish the connection.

4.10.3 Tunneling Troubleshooting

Using the original serial cable, please confirm valid communication between the serial
device and its application software on the PC with no iServers in between (direct serial
connection).

A successful connection is evident when the Remote Access drop down menu in the
Configuration page shows enable. This proves that the Serial Tunnel between the two
iServers is up and running. Otherwise, reset the power, first on the remote iServer and
then on the local iServer and recheck for Remote Access drop down menu as enable.

A quick way to check the LAN and serial tunneling connection is to separately access
each iServer WEB page via the Ethernet. If successful, this should prove a valid LAN
connection.

For serial tunneling, open a HyperTerminal session on the PC pointing to the same COM
port to which the Local iServer is connected and type/send some characters. This should
cause the Rx LED on the Local iServer to blink as it receives the data from the serial port
and onto the LAN. Accordingly, the Tx LED on the Remote iServer should blink as it
transmits the data from the LAN into the serial device. If no LEDs blink, then that could
possibly point to the iServer connection in trouble - particularly, the serial cabling and/or
the serial settings (Baud rate, stop bit, parity, etc.) throughout the communication path
between the PC, the iServer, and the serial device.

4.11 iPORT, COM Port Redirector

To obtain the iPORT software (iPORT.exe file) please use the phone number, as listed on
the cover of this manual, to contact the Sales Department nearest you.

To install the iPORT application, simply double-click on the iPORT.exe file and follow the
installation steps. The iPORT is compatible with Windows NT, 2000, and XP operating
systems.

4.11.1 iPORT Overview

The iPORT is a COM port redirecting software for Windows NT, 2000, and XP. Its
function is to redirect connections that are destined for a local serial (COM) port on a PC,
to an iServer network-enabling device on the LAN. In a direct serial connection,
application software can communicate directly over an RS232 or RS485 with a serial
device (Figure 4.26).

By installing iPORT software on the same PC, the iPORT will redirect the serial
connection from the COM port to the network port on that PC. The connection can simply
reach the serial device through an iServer sitting anywhere on an Ethernet network
(Figure 4.27). This connection redirection is totally transparent to the serial device and
its application software. Once the connection is up from the PC to the serial device, the
data is transmitted across the Ethernet network to the serial device and back from the
serial device to the PC, all through the iServer and the iPORT.

4.11.1 iPORT Overview (continued)

Figure 4.26 Direct Serial Connection

Figure 4.27 Redirect Serial Connection

4.11.2 iPORT Configurations

After the iPORT is successfully installed on your windows machine, you will have an
iPORT icon on your desktop and Control Panel window. By double-clicking on this icon,
you can start the application and the iPORT main window will appear on your screen
(Figure 4.28).

Click on "COM Ports" button and you will see the window on Figure 4.29. Select the
appropriate COM port (this should be the same COM port that your application software
uses). The selected COM port will then appear on the main iPORT window. By
highlighting the selected COM port, you will be able to add the IP address and the port
number to connect that COM port to the iServer on the network.

Up to 255 COM ports can be selected and each can have a different IP configuration
pointing to different iServers on the network. This enables users to simultaneously
redirect different application software to connect to serial devices attached to networked
iServers.

iServer IP Address – This is the IP address of the iServer that is connected to the serial

device on one end and attached to the Ethernet LAN on the other end. The iServer’s
default IP address is 192.168.1.200, which can be changed to fit your network IP
address range (see the iServer’s manual for details).

iServer Port Number – This is the port number for the iServer’s local serial port. The
default value is 2000. If this port number is changed in the iServer’s Configuration page
(see the iServer’s manual for details), the same number should be placed in the iPORT
window.

Activate – If this box is checked, the selected COM port will be available for network
connection. If it is unchecked, the selected COM port will be in sleep mode.

Timeout – This is the amount of time (in milliseconds) in which the iPORT keeps the

application software waiting before the device response is arrived. The default value is 5
seconds and it can be set between 0 to 10 seconds.

Status – This window shows the connection status as the iPORT makes connection to
the iServer or disconnects from the iServer. The connection status can be ideal,
connecting, connected, or disconnected along with the IP address of the iServer shown
in the Status window.

Apply button – To save the configuration for a selected COM port, click on the "Apply"
button and reboot your PC for settings to take place in your Windows registry.

Clear button – This button deletes the settings for a selected COM port.
Cancel button – This button closes the iPORT window without saving the settings.

In Figure 4.29, if a COM port number is dimmed and cannot be selected, it
means that the COM port is already used by another application or it could be a
physical serial COM port on that PC.

The serial communication settings (baud rate, data bit, stop bit and parity) of
your application software must be identical to the serial communication settings
of the iServer’s serial port and your serial device’s port connected to the iServer.
You can use a Web browser to log into the iServer and configure its serial port’s
settings (see the iServer’s manual for details).

4.12 Mail Notifier Software

The Mail Notifier Software can be used only with NEWPORT Electronics instruments.
For complete information of how to use the Mail Notifier software, click on the Help menu

of the main window.
The Mail Notifier software generates email notifications for alarm conditions. Users can

be notified automatically of alarm conditions monitored via internet connections
throughout the world. By use of the email forwarding of alarm conditions, alarm
conditions can be monitored on a network isolated from the internet and forwarded to
connections on the Internet.

The Mail Notifier utility operates under Windows 98, NT 4.0, 2000, and XP in conjunction
with existing email that supports the MAPI messaging
interface. If MS Outlook has been loaded, the MAPI
support should be available.

4.12.1 Mail Notifier Installation

The Mail Notifier must be loaded on a computer running
Microsoft Windows (versions specified earlier) using an
email program that provides MAPI access. Network
access must be available between this computer and
the iServer. Network access must also be available
from this computer to the appropriate email server and
from the email server to the recipient’s email server

Figure 4.30 iServer

Mail Notifier Main Window

38

4.12.2 Mail Notifier Program Options Setup and Configuration

Complete program setup requires:

• Entering a recipient for the email

• Specifying connection details to MAPI services.

•

Defining alarms for devices, and selecting how and when the email will be active.

Figure 4.31 iServer Mail Notifier Profile Setup

The “Send To” tab contains a field to specify an email address to which alarm
notifications will be sent (i.e. the recipient). Only one entry is permitted, in the address
field. Additional addresses can be placed into “More Addresses” list.

Email Connection (MAPI Access)

The following instructions work with some versions of Microsoft Outlook. Note though
that some email systems may prevent the use of Mail Notifier due to security constraints.

The simplest way to obtain a connection the the Email services is as follows:

1. Configure the Mail Notifier to connect to the email by displaying a Login Box. This
option is found by selecting View, Options from the Mail Notifier's menubar. Select
the "Email Setup" tab, mark the checkbox for "Use Login Box"

2. After Mail Notifier is configured to use the login box, the Mail Notifier can be started
without user intervention if your MS Outlook program is running beforehand.
Otherwise, the Mail Notifier will display a Login Box that should display the
necessary User Profile.

39

4.12.3 Mail Notifier Device Setting and Configuration

Device setup requires:

• Entering the IP

address for iServer device (for example 192.168.1.200).

• Specifying Socket number

(1000 or 2000 depending on iServer settings).

• Defining RS485 Unit # interface address (1 to 199). Enter "0" for RS232 interface
or for iServer.

• Entering Reading command

. Normally set to X01 to obtain reading from the devices.

If you want to change this setting, refer to HTTPget Section 4.8.

• Defining the Alarm setup (High/Low, High value, or Low value).

• Specifying Pause Interval

. It determines how many seconds each subsequential alarm

notification will be sent.

• Determining Monitor interval. It establishes the interval or time resolution in seconds
for which readings will be obtained from the device.

APPENDIX A GLOSSARY

User of this manual should be familiar with following definitions:

ARP (Address Resolution Protocol) is a protocol for mapping an Internet Protocol
address (IP address) to a physical machine address that is recognized in the local
network. For example, the IP address in use today is an address that is 32-bits long.
In an Ethernet local area network, however, addresses for attached devices are 48-bits
long. (The physical machine address is also known as a Media Access Control or
MAC address.) A table, usually called the ARP cache, is used to maintain a correlation
between each MAC address and its corresponding IP address. ARP provides the
protocol rules for making this correlation and providing address conversion in both
directions.

Ethernet is a network protocol defined by the IEEE 802.3 standard. Ethernet-based
networks use MAC Address rather then IP Address to exchange data between
computers. By using ARP and adding TCP/IP support, Ethernet devices may be
connected as part of the Internet. An Ethernet LAN typically uses coaxial cable or special
grades of twisted pair wires. The most commonly installed Ethernet systems are called
10BASE-T and provide transmission speeds up to 10 Mbps. Devices are connected to
the cable and compete for access using a Carrier Sense Multiple Access with Collision
Detection (CSMA/CD) protocol.

IP (Internet Protocol) is the method or protocol by which data is sent from one computer
to another on the Internet.

IP address (Internet Protocol address) is a 32-bit number that identifies each sender
or receiver of information that is sent in packets across the Internet.

IP Netmask is a 32-bit pattern of bits used to determine which part of the IP address is
the network portion and which part is the host portion.

MAC (Media Access Control) Address is your computer's unique hardware number.
When you're connected to the Internet from your computer, a correspondence table
relates your IP address to your computer's physical (MAC) address on the LAN.

Ping is a utility that tests the network connectivity. It is used to determine if the host is
capable of exchanging information with another host.

Port number/Socket number is a way to identify a specific process to which an Internet
or other network message is to be forwarded when it arrives at a server. It is a
predefined address that serves as a route from the application to the Transport layer or
from the Transport layer to the application of the TCP/IP system.

Sockets are a method for communication between a client program and a server
program in a network and defined as "the endpoint in a connection." Information
transferred across the Internet primarily occurs between sockets.

TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication
language or protocol of the Internet. When you are set up with direct access to the
Internet, your computer is provided with a copy of the TCP/IP program just as every
other computer that you may send messages to or get information from also has a copy
of TCP/IP. TCP/IP often is used as a general term to indicate generic access to the
Internet.

Appendix B IP Address

An IP address is a unique 32-bit address assigned to a computer and includes:

• A network ID number identifying a network.

• A host ID number identifying a computer on the network.

All IP addresses have been divided into three smaller groups (classes) A, B and C

• Class A addresses have 8-bits of network ID and 24-bits of host ID. They can support
a large number of hosts, approximately 2 = 16,777,216 computers per network.

The IP addresses range in binary from 00000001.xxxxxxxx.xxxxxxxx.xxxxxxxx

to 01111111.xxxxxxxx.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 1.x.x.x to 127.x.x.x

Class A network ID’s support a very large number of hosts.

• Class B addresses have 16-bits of network ID and 16-bits of host ID. They can
support approximately 216= 65,536 computers per network.

The IP addresses range in binary from 10000000 00000000.xxxxxxxx.xxxxxxxx

to 10111111 11111111.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 128.0.x.x to 191.255.xxx.xxx

Class B network ID’s support a medium number of hosts.

• Class C addresses have 24-bits of network ID and 8-bits of host ID. They can support
approximately 28= 256 computers per network.

The IP addresses range in binary from 11000000.00000000.00000000.xxxxxxxx

to 11011111.11111111. 11111111.xxxxxxxx

The IP addresses range in decimal from 192.0.0.xxx to 223.255.255.xxx

Class C network ID’s support a small number of hosts.

The rest of the addresses are divided into two classes, D and E.
Class D networks are not assigned to the host. They are used for multicasting.
The address range from 224.x.x.x to 239.x.x.x

Class E networks are experimental or reserved addresses.
The address range from 240.x.x.x to 247.x.x.x

44

Appendix C IP Netmask

IP Netmask or Subnet Mask is a 32-bit pattern of ones and zeros used to determine
network portion of an IP address from the host portion of the IP address. Subnet mask is
a network ID that is created by borrowing bits from host portion of IP address and using
them as part of a network ID. The table below shows a default subnet mask for address
Classes A, B, and C. Each bit that is set to "1" in the subnet mask corresponds to the bit
in the IP address that is to be used as the network ID. Each bit that is set to "0" in the
subnet mask corresponds to a bit in the IP address that is to be used as the host ID.

Address Class Mask Binary Value Mask Decimal Value

or Dotted Notation

Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0

If your network requires more network ID’s, you can extend the default subnet mask to
include additional bits from the host ID. This allows for additional network ID’s within the
network. The table below shows some examples of subnet masks and bits moved from
the hosts ID to create a new subnet.

Mask Dotted Notation Mask Binary Mask Bits

Class A

255.0.0.0 (Default) 0

255.192.0.0 2

255.224.0.0 3

255.255.255.192 2
…………………. .

255.255.255.254 6

To determine the number of valid hosts ID’s remaining after subnetting, use the following
equation: 2n– 2, where n is the number of octet digits left after the subnet mask.
