1: Introduction
The TCP2 RS Device Server connects seria l d evices to Ethernet networ ks using the IP
protocol family (TCP for connection-oriented stream applications and UDP for datagram
applications). A few of the different types of serial devices supported are listed below:
!"
Time/Attendance Clocks and Terminals
!"
ATM Machines
!"
CNC Controllers
!"
Data Collection Devices
!"
Universal Power Supply (UPS) Management Units
!"
Telecommunications Equipment
!"
Data Display Devices
!"
Security Alarms and Access Con trol Devices
!"
Handheld Instruments
!"
Modems
The TCP2 RS connect s these devices through a TC P da ta chann el or th rough a Telnet
connection to comp u ters or an other Device Serv er. Data grams can be sent by UDP.
1.1 Network Protocols
The TCP2RS uses IP protocol for network communications. The supported protocols are
ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, HTTP, and SNMP. For connections to
the serial port, TC P, UDP or Telnet protocols are used. Fir mwa re updates can be
performed using TFTP.
The Internet Protocol (IP ) defines addres s i ng, routing, and data block handling over the
network. The Transmi ssi on Control Protocol (TCP) assures tha t no data i s lost or
duplicated, and th at everything sent to the connection arrives correct ly at the targ et.
For typical datagram applications in which devices interact with other devices without
maintaining a point-to-p oi nt connection, User Datagr am Protocol (UDP) is used.
----------- TCP2RS -------------- User’s manual -------------------- page 6/43

1.1.1 Packing Algorithms
Two software select able packing algor ithms define how and when pa ck ets are sent to the
network. The standard algorithm is optimized for applications in which the TCP2RS is
used in a local environment, allowing for very small delays for single characters while
keeping the pack et cou n t low. The al ternate packing algor ithm mini mizes the packet
count on the network, and is especially usefu l in applications in a routed Wi de Area
Network (WAN). Adjusting parameters in this mode can economize the network data
stream.
1.1.2 Ethernet (MAC) Address
The Eth ernet addr es s is also referred to as the hardware address or the MAC address. The
first three bytes of the Ethernet Address are fixed. The fourth, fifth, and sixth bytes are
unique numbers assigned to each TCP2R S .
Table 1-1:
Sample Ethernet Address
00-20- 4A -1 4- 01-18 or 00: 20 :4A:14:0 1: 18
1.1.3 Internet Protocol (IP)
Address
Every devi ce connected to an IP network must have a uniqu e IP ad dress. This ad dress is
used to reference the specific TCP2RS. See A p p endix F for more information on IP
Addressing.
1.1.4 Port Number
Every TCP connect ion and every UDP datagram is d efined by a desti n ation IP address
and a por t n um ber. For example, a Telnet applicati on commonl y uses port number 23. A
port number is similar to an extension on a PBX system.

2.2 Installing the TCP2RS
The following diagram shows a properly installed TCP2RS.
To install the TCP2 RS, complete the foll owing step s in order. Refer to the n um bers in the
previous figure.
1
Connect a serial device to the TCP2RS.
2
Connect an Ethern et cable to th e 1 0 BAS E-T port.
----------- TCP2RS -------------- User’s manual -------------------- page 9/43

3
Supply power to the TCP2RS.
Note:
The required input voltage is 220VAC.
4
Supply power to the serial device.
3: Getting Started
This chapter cover s the required steps to g et the TCP2 RS on-line and work ing. Th ere are
two basic methods used to log into the TCP2RS and setup the IP address:
!"
Network Port Login: Make a Telnet connection to the network port (port 9999).
!"
Serial Port Login: Connect a terminal or a P C running a terminal emul ation
progr am directl y to the TCP2RS’s serial port.
It is important to consider the following points before logging into and configuring the
TCP2RS:
!"
The TCP2 RS’ s I P address mu s t be con figur ed before a network connect i on is
available.
!"
Only one person at a time may be logged into the configuration port (port 9999).
This eliminates the possibility of several people simultaneously attempting to
configu re the TC P 2 RS.
!"
Network port logins cannot be disabled. The system manager will always be able
to access t he unit. Howe ver, thi s port can be passw ord protected.
!"
Only one terminal at a time can be connected to the serial port. (In RS-485 mode,
the TCP2RS is capable of multidrop connections.)
3.1 Default IP Address
The TCP2RS ships with a default IP address of 192.168.0.25, if you want to use DHCP
you have to config IP 0.0.0.0 which automatically enables DHCP within the TCP2RS.
Provided a DHCP server exists on the network, it will supply the TCP2RS with an IP
address, gat e way address, and su bnet mask when the TCP2RS boots u p. (If no DHCP
server exists, the TCP2RS will respond with a diagnostic error: the red Diagnostic LED
----------- TCP2RS -------------- User’s manual -------------------- page 10/43
10
blinks continuously and the green Status LED blinks five times). This address will not
appear in the TCP2RS’s configuration screens; however, if you enter Monitor Mode from
the serial port with network connection enabled (see Monitor Mode), and issue the NC
command, you will see the TCP2RS’s IP configuration.
3.2 IP Address Configuration
The TCP2 RS’ s I P address mu s t be con figur ed before a network connect i on is availa bl e.
If the IP address was not set automatically via DHCP, set it now using a network or serial
port login and the setup (configuration) menu.
3.2.1 Network Port Login (1)
The easiest way for setting up the IP direction of the TCP2RS converter is using the little
utility called TCP2RSSetup that comes with the converter.
First of all we will write down Ethernet address that comes printed on every device label.
This address is unique and different from other network devices. It’s the hardware
address that every interface has (something like 00-20-4A-61-05-19).
Into the “Extras” disc that comes with the converter, there is an Utility called
TCP2RSSetup. This utility is made for configuring the IP address of the converter. Steps:
1- Star t the program
2- Insert the Hardware address that comes with the converter, and desired IP
address.
3- Click Configurar (This will assign temporarily an IP address to the converter
and opens an internet explor er page for configurin g it)
4- Click Connect and Server Properties
5- Enter desired IP and netmask ans click Update settings
Note: This utility only links IP address with hardware address, but it is not
stored in device’s memory, until we enters into config mode and update
this settings.
3.2.2 Network Port Login (2)
The ARP method is ava ilable under UNI X and Windows-based systems. If the TCP2RS
has no IP a d dress, it wil l s et its addr es s from the fir st directed TCP /IP packet it r eceives.

On a UNIX host, cr eate an entr y in the host’s ARP table using the inten d ed I P

address and the hardwa re ad dress of t he TCP2RS, which is found on the product
label.
Figure 3-1:
ARP on UNIX
arp -s 19 1.12.3.77 00:20:4a:xx:xx:xx
In order for the ARP command to work on Windows, th e ARP table on the PC must
have at least on e IP addr e s s defined other th a n its own. If the ARP tabl e is empty, the
comma nd w ill return an erro r message. Type
ARP -A
at the DOS command prompt to
verify that there is at least one entry in the ARP table.
If the local machine is the only entry, ping another IP address on your network to build a
new entry in the ARP table; the I P address mus t be a h ost ot her than the machin e on
which you are workin g. Once ther e is at least on e ad d itional en try in the ARP table, use
the following command to ARP an IP address to the TCP2RS:
Figure 3-2:
ARP on Windows
arp -s 19 1.12.3.77 00-20-4a-xx-xx-xx
2
Now open a Telnet connection to port 1. The connection will fail quickly, but the
TCP2RS will temporarily change its IP address to the one designated in this step.
Figure 3-3:
telnet 191.12.3.77 1
Telnet to Port 1
3
Finally, open a Telnet connection to port 9999 and set all required parameters.
Figure 3-4:
Telnet to Port 9999
telne t 191.12.3.77 9999
Note:
This IP address is temporary and will revert to the default value
when the TCP2RS’s power is reset, unless you log into the TCP2RS
and store the changes permanently. Refer to Chapter 4 for
instructions on permanently configuring the IP address.
3.2.3 Serial Port Login
1
Connect a console t er minal or PC runn ing a terminal emulation progr am to the
TCP2RS’s serial port. The default serial port settings are 9600 baud, 8 bits, no
parity, 1 stop bit.
----------- TCP2RS -------------- User’s manual -------------------- page 12/43
12
2
To ent er Setup (con figuration) Mode, c ycle t he TCP2RS’s po wer (power of f and
back on) . A ft er power-up the self-test begins and th e red D iag nostic LED starts
blin king. You have on e s econd to ent er th ree lowercase "x" char acters.
Note:
The easiest way to enter Setup Mode is to hold down the “x” key at
the terminal (or emulation) while powering up the TCP2RS.
3
Select 0 (Server Config urat ion) and follow th e prompts until you get to IP a ddres s.
4
Enter the new IP address.
5
Select 9 to save the configuration and exit Setup Mode.
The TCP2RS performs a power reset.
----------- TCP2RS -------------- User’s manual -------------------- page 13/43

4: Configuration
Cer t ain parameters must be c onfig ured be fore the TCP2RS can func tion on a net work.
The TCP2 RS can be local ly or remotely configured using the following proced u res:
!"
Use a standard Web brows er to access the TCP2RS’s intern al Web p ages and
configu re the unit over the net work. Thi s i s the easiest an d preferr ed m ethod.
!"
Use a Telnet connection to con figure the unit over the network.
!"
Use a term inal or terminal emulation program to acces s the seria l p ort locall y.
The TCP2RS’s configuration is stored in nonvolatile memory (NVRam) and is retained
withou t power. Th e configuration can be changed at an y time. The TCP2 RS p er forms a
reset after the configuration has been changed and stored
.
4.1 Network Configuration
4.1.1 Using a Web Browser
If your TC P 2 RS already has an IP address ( s ee Chapter 3, Getting Started), you can log
into it using a standard Web browser with Java enabled.
1
Type the TCP2RS’s IP addr ess into th e Web browser’s URL (Addr ess/ Loca t ion)
field.
Once you have connected to the TCP2RS, you will see the device Web Manager
interface.
2
Select Connect to login and gain access to the configuration menu.
3
Use th e men u t o n avigate to subp ages where you can confi gure server setting s .
