4. Connectors
Inputs and outputs locations are shown below:
•J1 –mode selection jumper for digital input – dry contact (close) and logic level (open);
•ETHERNET - 10/100-BaseT RJ45 connector
•POWER – ø2mm power jack

5. ED indicators
The following indicators show the status of the controller :
•Relay status 1÷8 (green) – these LEDs are illuminated whenever the corresponding
relay is activated
•Power (red) – this flashes when the power supply is turned on;
•Busy (yellow) – this LED indicates that someone is connected to the controller
through web interface;
• ink (green) – this LED is located on the Ethernet connector. It indicates that the
device is connected to the network ;
•Act (yellow) – this LED is located on the Ethernet connector. It flashes when activity
is detected on the network.
6. Example Application
6.1 Remote control
The controlled device is connected in series with the relay contacts. Users can operate
TCW180 using a web browser or by using custom SN P applications. The relay outputs are
managed independently of each other.

7. Installation
Please follow the steps below for proper installation :
1. ount the controller in a dry and ventilated place.
2. Connect the Ethernet port to a 10/100 Base T Ethernet connection. For direct
connection to a PC use a “crossover” cable.
3. Connect the I/O pins of the controller according to the required application.
4. Connect the power supply.
If the red LED is blinking, it indicates that the power supply is OK. By default TCW180 comes
with the following network settings:
IP:192.168.1.2 , Subnet Mask: 255.255.255.0 , Default Gateway: 192.168.1.1
Communication with TCW180 may be established by assigning a temporary IP address to the
configuration computer that is on the same network (for example 192.168.1.3). To get access to
the web interface of the controller, you should type the following URL into the browser :
http://192.168.1 2 . If the network settings are correct, the “Login” page will appear.
8. Web-based setup.
The web based interface allows the TCW180 to be configured, controlled and monitored via
web browser. Recommended programs are ozilla Firefox, Chrome and Internet Explorer 6 (or
higher version) at 1024x768 resolution.
8.1 ogin page
After opening the Login page, authorization data must be entered ( by default
username=admin , password=admin). It is recommended to change the username and password
to prevent unauthorized access to the controller.
The controller supports only one active session – only one user (administrator) can operate
the device. If another user tries to login, the following message appears: “Someone’s logged in”

The active session will be terminated automatically, if the current user stays inactive for 2
minutes.
8.2 Monitoring page
After successful authorization, the onitoring page appears:
The onitoring page provides information about the state of the digital input and relay
output of the controller. To change the state of the relays , the “ON/OFF” buttons should be
pressed. If the Pulse button is pressed the relay will change its state for the time specified in the
“Pulse Duration” field in the “I/O Setup ” page. Three buttons are located on the bottom of the
page:
-All ON – clicking this button will turn all relays ON
-All OFF – clicking this button will turn all relays OFF
-Pulse All – clicking this button will change the states of all relay outputs fir the time
specified in the “Pulse Duration” field in the “I/O Setup ” page.
8.3 Account page
This page allows to change the user name and password for the web interface. After
entering the desired information, click the “Save” button.

8.4 Network Setup page
The Network parameters are set on this page. The following parameters can be changed:
•IP configuration – IP Address configuration can be static or dynamic (DHCP)
•IP address, Subnet mask , Default gateway – these fields are active if IP address is
static
•Host Name
•MAC – device AC address
If multiply TCW180 controllers are used on the same network, please change the IP address
after connecting the device to the network. This will avoid devices installed on the network with
the same factory default IP address at the same time. It may be necessary to clear the arp cache
each time you connect new device to the network. This is done by typing arp -d in the command
prompt of a Windows computer.
In order to reduce network traffic and to limit the access, the controller supports VLAN and
AC address filtering. In addition to the AC address of the Default Gateway, another 2 AC
addresses can be added to the filter. The filter is enabled by marking the appropriate check box
after the AC address.
To set up the S TP server the following fields should be completed:
•Mailserver [IP:port] – IP address and port number of S TP mail server
•E-mail – sender mail
•Username&Password – these fields are required if using S TP server with authentication

8.5 SNMP Setup page
TCW180 supports SN P v.1 that enables the device to be part of large monitoring and
control networks. The possible settings are:
•SNMP Configuration – enable SN P v.1
•Read-Write community – performs client authentication
•Read-Only community – performs client authentication
SN P trap messages are sent for the following conditions:
-if event occurs on Digital Input (the signal changes its state)
-device restart
The following parameters can be changed:
•SNMP Traps – enable SN P trap messages
•IP address – IP address of the receiving host
•Community string – performs client authentication
•Trap Interval - time interval for SN P trap messages
•Max. number of Traps – maximum number of SN P trap messages sent, if trap
condition is present

8.6 I/O Setup page
The following parameters can be set for the relays:
•Description – brief description of the output, maximum 10 characters should be used.
•Pulse Duration – time for which the relay changes its state, by pushing the "Pulse" button
on " onitoring" page. This setting applies to all 8 relays
TCW180 can be set to send e-mail alerts if an event occurs on the digital input. The following
fields should be filled:
•Mail to – recipient e-mail address
•Subject – e-mail subject
•Message – e-mail body
In the example above, if an event occurs (closing contact) the controller will send e-mail
message to [e-mail] with subject "alarm" and e-mail body "door open".

9. SNMP setup
TCW180 can be configured and monitored through SN P (Simple Network
anagement Protocol). This could be done using every SN P v.1 compatible program.
Parameters that can be changed, are grouped according to their functions in the tables below.
To obtain a valid OID number it is necessary to replace the “x” symbol with the prefix
”.1.3.6.1.4.1.17095”. To save the changes you should set a value ”1” of the
configurationSaved (OID x.8.0).
