1. Short description

TCW112-WD is an Ethernet controller, which is designed to work in IP-based networks. It has 1

digital and 1 analog input, 1-Wire interface and 1 relay output. It can be managed by WEB interface
and/or SNMP programs.

The relay can be activated either remotely (WEB, SNMP etc.) or locally - from presence/absence
of ping (echo request or echo replay). SNMP trap can be sent for every monitored parameter
(temperature, humidity, analog voltage and dry contact) if it goes outside of previously predefined
range. Special schematic is utilized for long 1-Wire support.

2. Features

10 Mb Ethernet connectivity;
Password protected, web based configuration and control;

1 digital input with " dry contact" and "logic level" modes;

1 analog input with 0 to 60VDC range;
1 relay with NO and NC contacts;
Long 1-Wire support for 1 temperature (TST1XX) or temperature/humidity (TSH2xx) sensor;
SNMP v.1 support;
SNMP traps sending for alert conditions;
VLAN support;
MAC address filtering;
Remote FTP firmware update.

4. Connectors and LED’s

The location of the connectors and LED’s are shown below:

4.1 Connectors

The device has following connectors:

Power -ø 2mm connector, central positive;
Ethernet - RJ45 connector;
Screw terminals:

- GND ground for 1-Wire sensor;

- DAT data input/output of 1-Wire sensor;

- +VW power supply for 1-Wire sensor;

- GND ground for analog input;

- AIn analog input;

- +VA power supply for analog sensors;

- GND ground for digital input;

- DIn digital input, operates either in “dry contact” mode (J1 is closed) or

“logic level” mode (J1 is open);

- Relay normal open and normal close contacts are available.

4.2 LED indicators

Five LED’s show the status of controller:

STS (red) – flashes when the main program of controller is executed;
LOG (yellow) – indicates that somebody is logged via WEB interface;
REL (green) – indicates that the relay is activated;
Link (green) – located on the Ethernet connector, indicates that the device is connected to

the LAN;

Act (yellow) – located on the Ethernet connector, indicates that activity on the LAN is

detected.

5. Powering

TCW112-WD is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for

use in the conditions of overvoltage category II, and priorly assessed for compliance with safety
requirements. The power supply equipment shall be resistant to short circuit and overload in secondary
circuit.

When in use do not position the equipment so that it is difficult to disconnect the device from
the power supply.

6. Installation

Installation consists of mounting the device, connecting to an IP network, connecting inputs and
outputs, providing power and configuring via a web browser.

This device must be installed by qualified personnel.

This device must not be installed directly outdoors.

This device should be mounted in a clean and dry location room. Ventilation is recommended for
installations where ambient air temperature is expected to be high.

The device should be installed in not flammable box. See Appendix-A, fig. 1 for mechanical
details. Maintain spacing from adjacent equipment. Allow 50 mm of space on all sides, as shown on fig.2
in Appendix A. This provides ventilation and electrical isolation.

7. Configuration

Please follow the steps below for proper installation :

1. Mount the controller in a dry and ventilated place.

2. Connect the Ethernet port to a 10/100MB Ethernet network. 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 (STS) blinks, the main program of controller is executed. By default TCW112-WD is
delivered with the following network settings:

IP address: 192.168.1.2, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1

Communication with TCW112-WD can be established by assigning a temporary IP address to the
computer. This address should be in the same network (for example 192.168.1.3). To get access to the web
interface, you should type http://192.168.1.2 into the browser address field.

If the network settings are correct, the “Login” page will appear.

The web based interface allows configuration, monitoring and control. Recommended browser is
Internet Explorer at 1024x768 resolutions.

7.1 Login 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.

TCW112-WD_R2 - June 2014 Page 5

The controller supports one active session – only one user can operate the device. If another user
tries to login, the message “Someone’s logged in” appears:

The active session will be terminated automatically, if the current user stays inactive for 2 minutes.

7.2 Monitoring page

After successful authorization, the “Monitoring page” appears:

The “Monitoring page” provides information about the state of digital and analog inputs, relay

status, temperature and humidity (if a sensor is connected).

Digital input can be used for monitoring the state of discrete devices – motion sensor, door contact,
relay contact, alarm output etc. The digital input is not galvanic isolated. One side of the contact is
connected to “Digital In” and the other side is connected to “GND” pins. Digital input is sampled every
10mS. The change of input status is considered valid if the same value is read in two consecutive samples.
