Operating mode is selected by jumper DI1/DI2 – closed for “dry contact” and open for “logic level”. By default, jumpers are closed.
LED indicators
The following indicators show the status of the controller:
- Relay1/Relay2 (green) – these LEDs are illuminated whenever the corresponding relay is activated (the NO contact is closed and the NC contact is open);
- Sts (red) – flashes when the main program of the controller is executed;
- Log (yellow) – indicates that somebody is logged via the WEB interface;
- Net (green/red) – red when the device is linked, yellow when there is an activity.
Powering
TCW122B-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 the secondary circuit. When in use do not position the equipment so that it is difficult to disconnect the device from the power supply.
Installation
- This device must be installed by qualified personnel.
- This device must not be installed directly outdoors.
- The installation consists of mounting the device, connecting to an IP network, connecting inputs and outputs, providing power and configuring via a web browser.
- TCW122B-WD can be wall or flat, not flammable surface mounted, in a clean and dry location room. Ventilation is recommended for installations where the ambient air temperature is expected to be high.
- Mount the device to a wall by using two plastic dowels 8x60mm (example Würth GmbH 0912 802 002) and two dowel screws 6x70mm (example Würth GmbH 0157 06 70). Attach the screws to the surface vertically. See Appendix-A, fig. 1 for mechanical details.
- Maintain spacing from adjacent equipment. Allow 50 mm of space on all sides, as shown in fig.2 in Appendix A, this provides ventilation and electrical isolation.
Configuration
Please follow the steps below for proper installation:
- Mount the controller in a dry and ventilated place.
- Connect the Ethernet port to a 10/100MB Ethernet network. For direct connection to a PC using a “crossover” cable.
- Connect the I/O pins of the controller according to the required application.
- Connect the power supply.
If the red LED (STS) blinks, the main program of the controller is executed.
By default TCW122B-WD comes 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 TCW122B-WD can be established by assigning a temporary IP
address to the computer. This address should be on 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.
If the network settings are correct, the “Login” page will appear.
The web-based interface allows configuration, monitoring, and control.
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.
The controller supports one active session – only one user can operate the device. If another user tries to log in, the message “Someone’s logged in” appears:
The active session will stay open until the “Monitoring” page is open. Inactivity on other pages or closing the browser without logoff will terminate the session automatically in 4 minutes.
Monitoring page
After successful authorization, the “Monitoring” page appears:
The “Monitoring” page provides information about the state of the relays and
digital inputs, values of analog voltages (applied on analog inputs),
temperature and humidity.
The state of the relay can be changed by appropriate “ON/OFF” button. To
change the state of the relay for a specified time, “Pulse” button should be
pressed. Duration of the pulse is specified in “Pulse Duration” field of “I/O
Setup” page.
Digital inputs can be used for monitoring the state of discrete devices –
motion sensor, door contact, relay contact, alarm output etc. All digital
inputs are not galvanic isolated. One side of the contact is connected to
“Digital In” and another side is connected to “GND” pins.
Digital inputs are sampled every 30ms. The change of input status is
considered valid if the same value is read in seven consecutive samples.
Network Setup page
The Network parameters are set on this page. The following parameters can be changed:
- IP configuration – IP Address can be static or dynamic (DHCP server should be present in the network);
- IP address, Subnet mask, Default gateway – these fields are active if the IP address is static;
- Host Name – up to 16 symbols
- MAC – device MAC address.
The good practice is to change the default IP address of the controller
immediately after first power-on. This will avoid collisions if many devices
are used on the same network. It may be necessary to clear the arp cache, each
time you connect a new device to the network. This is done by typing “arp –d”
in the command prompt window of the computer.
VLAN and MAC address filtering are supported. Up to 3 MAC addresses (including
Default Gateway) can be active in MAC filtering.
Attention! If you are not familiar with VLAN and MAC filtering, leave
these sections by default.
Username and password for WEB access to TCW122B-WD can be changed in the Web Access section. Setting the authentication to “disabled” will provide access to monitoring page without entering username and password. The HTTP port can be changed also in this section.
SNMP Setup page
TCW122B-WD supports SNMP v.1. This enables the device to be part of large monitoring and control networks. The possible settings for “SNMP” section are:
- SNMP Configuration – enable/disable SNMP;
- SNMP Port – allows standard port changing;
- Write/Read community – performs client authentication;
- SNMP Traps – enable/disable SNMP trap messages;
- IP address – IP address of the receiving host;
- Community string – performs client authentication;
- Trap Interval – time interval in seconds for SNMP trap messages;
- Max. Traps number – the maximum number of SNMP trap messages sent if trap condition is present.
SNMP traps are sent if:
- event occurs (status change) on Digital Input 1 or Digital Input 2;
- measured voltage on Analog Input 1 or Analog Input 2 goes outside the range;
- measured temperature goes outside the range;
- measured humidity goes outside the range;
- restart condition.
I/O setup page
I/O settings can be made here. For temperature, humidity and analog value MIN, MAX, and HYSTERESIS values can be set. These values define the thresholds for all monitored parameters.
When the measured value goes out of range SNMP trap (if enabled) will be sent. Leaving range is considered when the parameter goes lower than MIN values or higher than MAX. Coming back in the range is considered when the parameter goes higher than (MIN + HYSTERESIS) or lower than (MAX – HYSTERESIS).
For IP watchdog monitoring following parameters can be set:
- Mode – outgoing (echo request) or incoming (echo replay) mode can be chosen;
- IP address – IP address of ICMP corresponding host;
- Activation options – the relay activation options – Pulse OFF, Pulse ON, Permanent OFF, Permanent ON
- Outgoing ping interval – the time between two echo requests;
- Ping timeout for activation – timeout before activation of the relay;
- Maximum number of activations – the maximum number of activation of the relay (restarts) after the timeout has expired.
Ping timeout for activation should be longer than Outgoing ping interval.
Relays can be activated manually from the WEB interface or automatically in
function of the watchdog.
By default, relay state changes via the WEB interface are memorized in non-
volatile memory. After the power on, the relay goes in its last state, before
the power down.
If the “Save relay state after change via WEB” is No, after power on the relay
is always OFF.
The guaranteed write cycles (every change saving) are 100000.
When Web/SNMP activation is selected, “Pulse” and “ON/OFF” buttons on
“Monitoring” page are active. The duration of the pulse for relay activation
can be set from 1 to 253 seconds.
For every sensor, analog input, digital input and relay description with a
length of 11 characters can be set.
Temperature units can be changed between Fahrenheit and Celsius.
Automatic monitoring page refresh interval can be set from 1 to 253 second.

Application examples
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Teracom Ltd. cannot assume responsibility or liability for actual use based on the examples and diagrams.
Watchdog
TCW122B-WD is set to send a periodic ping to AP (Local network) and the remote server (Internet). If there is no answer in “Ping timeout for restart”, the corresponding relay is activated in order to reset particular network equipment.
Dry contact monitoring
The monitored contacts are connected to digital inputs (Din1 and Din2) and ground (GND). Changes in the state of contacts can be monitored either by WEB or SNMP interface. If SNMP traps are allowed and properly set, every change of state will generate a trap to the server.
Wire Bus
- Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect several sensors over short wiring. The bus carries power and a single data wire. It is not suitable for long distances or environments with EMC interference.
- We strongly recommend reading Maxim’s 1-Wire tips at https://www.maximintegrated.com/en/design/technical-documents/tutorials/1/148.html.
- The total wiring length should be up to 30m, although functionality has been achieved in the longer distance. We cannot guarantee error-free operation over mentioned wiring length.
We guarantee proper operation only with our 1-Wire sensors series TST1XX and TSH2XX.
SNMP protocol
TCW122B-WD can be configured and monitored through SNMP (Simple Network
Management Protocol). This could be done using every SNMP 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 ”1.3.6.1.4.1.38783”.
To save the changes configurationSaved (OID x.3.13.0) should be set to “1”.
