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.

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.

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.
The default password for the system administrator is widely known. To

changed. You can change the password using the Change Password
page on the Xenta web site.
To change the password
1In the navigator, expand Configuration-User Administrator, and
click Change Password.
2In the Old password box, type the old password. In the example,
“root”.
3In the New password box, type the new password. In the example,
“seagull3”.
4In the Confirm new password box, confirm the new password.
5Click Save.
Use the new password the next time you log on as system administrator.
If you do not have access to the root password when you try to connect
to a Xenta 500/700/913, a temporary user name and password can be
used. The temporary password is generated by based on the Session ID
displayed on the Login page.
Send the Session ID to helpdesk@tac.com, which generates and returns
a temporary password. Then type the Session ID in the Username box
and the temporary password in the Password box.
Tip
•You can select the text on the login page, copy it and then paste it
into the e-mail message and the Username box.
The Session ID changes each day, so the temporary password is only
valid on the day it is generated.

The Xenta 527 connects to the I/NET controller LAN through terminal
19 and 20 of its lower terminal block connector.
Fig. 5.10: Controller LAN Connections
To connect the Xenta 527 to an I/NET controller LAN
1Connect the positive (+) line to position 19.
2Connect the negative (–) line to position 20.
3Splice shield wires together at each device on the controller LAN,
and connect to a good earth ground at one location only. Ensure
that shield wire continuity is maintained across the controller
LAN.
Note
•The polarity of the RS485 connection is important. It is recommended that you observe the network’s polarity convention (the
positive line connected to position 1, and the negative line to
position 2, on all devices). This convention will help ensure consistent voltage measurements should diagnostic troubleshooting
become necessary.
The Xenta 527 is intended for use on an Ethernet LAN. However, you
can also directly connect an I/NET host workstation to the RS-232 A
port on the front of the Xenta 527. This allows the directly connected
I/NET host to communicate with devices on the Xenta 527’s controller
LAN. This type of connection can also be used when you are configuring the Xenta 527’s communication parameters.
In order to directly connect an I/NET host workstation to the Xenta 527,
you must connect a cable from the workstation’s serial COM port to the
Xenta 527’s RS-232 B port. TAC Xenta Programming Serial Kit
007309200 provides that adapters and cables required for this type of
connection, as well as for a console connection. to the Xenta 527’s
RS-232 B port.
Once you have connected an I/NET host workstation to Xenta 527, set
I/NET’s link type to “NetPlus Router” in the I/NET Configuration editor. Refer to TCON298, I/NET Seven Getting Started, for complete
instructions.

6.5.1Connecting to a MicroNet NCP network (MN MI not used)
The Xenta 555 connects to the MicroNet controller network through terminals 5 and 6 of its upper terminal block connector.
Fig. 6.9: RS485 LAN connections (MicroNet NCP network)
To connect the TAC Xenta 555 to a MicroNet controller
LAN
1Connect the positive (+) line to position 5.
2Connect the negative (–) line to position 6.
Join the shield wires together at each device on the controller LAN, and
connect to a good earth ground at one location only. Ensure that shield
wire continuity is maintained across the controller LAN.
If Belden 9502 dual-twisted pair is being used (recommended), join
together both wires of the second twisted pair and connect them to the
LAN REF terminal at each MicroNet device (refer to the relevant
MicroNet data sheets for details). For the Xenta 555, connect the second
twisted pair to Pin 2 (G0).
Caution
•Belden 9502 dual-twisted pair cable contains one black wire in
each twisted pair. It is essential to good communications that
these black wires are not crossed over between pairs.
Note
•It is important to ensure that the polarity of the network connections is consistent throughout the system, that is, (–) is connected
to (–) and (+) is connected to (+).
