1.3Terminology
•DHCP – Dynamic Host Configuration Protocol. A protocol for
assigning dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP address every
time it connects to the network. In some systems, the device's IP
address can even change while it is connected. DHCP also supports a mix of static and dynamic IP addresses.
•DNS – Domain Name System (or Service), an Internet service that
translates domain names into IP addresses. Because domain names
are alphabetic, they are easier to remember. The Internet however,
is based on IP addresses. Consequently, every time you use a
domain name a DNS service must translate the name into the corresponding IP address.
•FTP – File Transfer Protocol. An application used to transfer files
from one host to another and to store the files on the requesting
host.
•IP Network – A network (for example Internet or Intranet) using
the Internet Protocol (IP) and IP addressing.
•LTA – LonTalk Adaptor . A computer interface with the LonWorks
network.
•NTP – Network Time Protocol. An Internet standard protocol
(used on top of TCP/IP) that assures accurate synchronization to
the millisecond of computer clock times in a network of computers.
•SNMP – Simple Network Management Protocol. A set of proto-
cols for managing complex networks. SNMP works by sending
messages, called protocol data units (PDUs), to different parts of a
network.
•SNTP – Simple Network Time Protocol. A simplified version of
NTP.
•SSL – Secure Sockets Layer. A protocol developed by Netscape
for transmitting private documents via the Internet. By convention,
URLs that require an SSL connection start with https: instead of
http:.
•TCP/IP – Transmission Control Protocol/Internet Protocol. The
suite of protocols that when combined create the “language of the
Internet”.

The Xenta 500/700/911/913 all share the same hardware design and
hardware layout. For a more detailed description on each Xenta device,
see the Docnet site at
2.1Hardware
The Xenta device is designed around a microprocessor. The module
consists of two parts, an electronics unit containing the circuit boards
and contacts, and a terminal part including the terminal blocks.
Fig. 2.1: The Xenta device – Electronics and terminal.
•Power Outage Protection – Settings like configurations and web
pages are stored in the non-volatile (flash) memory and will not be
lost in the event of a power outage. A built-in capacitor maintains
operation of the RAM memory for at least 72 hours in the event of
a power outage.
•Real Time Clock – The real time clock provides the internal event
log with a time stamp. The capacitor maintains operation of the
clock for at least 72 hours in the event of a power outage.
•Mounting – The Xenta device is cabinet mounted on a TS 35 mm
norm rail EN 50022.
To simplify commissioning, the terminal part can be pre-mounted
in the cabinet.
If the Xenta device is to be wall-mounted, a wide range of standardized boxes are available.

The RS-232 A port (position 21) is used for serial communication
between the Xenta device and the connected unit. The connector is an
8-pin modular jack (RJ-45).
Note
•The interface RS-232 A (position 21) and interface RS-485 A
(position 5–8) are internally connected to port A on the processor. Only one should be connected.
The port uses the following signals:
87654321

Serial Port – RS-232 B
The RS-232 B port is used for communication between the Xenta
device and a computer. It is used for configuration of the Xenta device
using Windows HyperTerminal. The connector is a 4-pin modular jack
(RJ-10).
The port uses the following signals:
4321
Fig. 2.4: Connection using basic RS-232 signals, primarily intended for a
computer running, for example Windows HyperTerminal during the
configuration phase.
Ethernet Port – 10Base-T
The Ethernet 10Base-T port is used for communication between the
Xenta device and the TCP/IP network.
The Xenta can enter a fail-safe state if a severe problem arises in the system program.
The unit can be forced into fail-safe mode by shorting terminals 9 and
10 in Fig. 2.2 during power-up. This can be useful if the system program
experiences problems.
The overall Run indicator (position 3 in Fig. 2.6) will show a steady red
light in the fail-safe state.
2.1.4LEDs
A number of light-emitting diodes (LEDs) on the Xenta device indicate
that the application program is running and when communication is in
progress.

internal port A is used for both.

When you use Windows HyperTerminal you need to set up a connection. Once created it can be used when required. In the example below
a Xenta 511 is configured.
To configure Windows HyperTerminal
1Connect the Xenta to the engineering PC.
2On the Start menu, point to All Programs, point to Accessories,
point to Communications, and then click HyperTerminal.
3In the Connection Description dialog box, in the Name box, type
a name that describes the connection. In the example “Connection
to Xenta 511”.
4In the Icon box, click the required icon.
5Click OK.
6In Connect To dialog box, in the Connect using list, click the
COM port used in step 1 above.
7Click OK.
8In the COM1 Properties dialog box, in the Bits per second list,
The configuration parameters for the Xenta are entered using HyperTerminal. The parameters enable the Xenta to communicate using its
TCP/IP port.
Important
•Because the Xenta’s TCP/IP default parameters are set at the factory, you can immediately access it using a web browser and
change the parameters without having to use HyperTerminal.
The default parameters are:
•IP address: 192.168.255.2
•Subnet mask: 255.255.255.0
To configure the TAC Xenta
1Start Windows HyperTerminal using the connection created in
Section 2.2.2, “Configuring Windows HyperTerminal”, on
page 26.
