TCW210-TH-R1.16- November 2022 Page 1
1. Introduction
TCW210-TH is a temperature and humidity data logger with an embedded WEB server. Real-time data
and charts of temperature, humidity and dew point can be monitored with a standard web browser
(no special software is needed). Standard protocols as SNMP, MODBUS/TCP, and HTTP/API are
available for M2M applications. The device supports also interface to popular IoT analytics –
ThingSpeak.
The Ethernet temperature logger supports up to eight temperature or humidity-temperature sensors.
All they can be connected either to the 1-Wire interface, popular for home automation or to more
robust MODBUS RTU over RS-485.
All monitored parameters can be recorded, in internal FLASH memory. The records are made on the
previous set time interval and/or on an alarm condition. The memory is large enough for at least 36
days with records on every minute. The log file can be periodically uploaded on a dedicated server by
HTTP/HTTPS Post. The stored data can be monitored on 4 graph pages.
XML/JSON file with all monitored parameters can periodically upload to a dedicated server by
HTTP/HTTPS Post.
For every monitored parameter e-mails and SNMP traps for up to 5 recipients can be sent. Alarm alert
can also be sent by HTTP/HTTPS Post with XML/JSON status files.

6.2.1. Power supply
TCW210-TH is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for
use in the conditions of overvoltage category II, and prior assessed for compliance with safety
TCW210-TH-R1.16- November 2022 Page 4
requirements. The power supply equipment shall be resistant to short circuit and overload in a
secondary circuit.
When in use, do not position the equipment so that it is difficult to disconnect the device from
the power supply.
6.2.2. 1-Wire interface
1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect
several sensors over short wiring. It is not suitable for long distances or environments with EMC
interference.
The maximum number of sensors (1-Wire or RS-485) connected to TCW210-TH is 8.
The device supports temperature and humidity-temperature sensors. Connected sensors are
automatically detected and the appropriate dimension is assigned.
It is strongly recommended to use “daisy-chained” (linear topology) for multi-sensors systems:
It is strongly recommended to use only UTP/FTP cables and keep total cable length up to 30m.
Although functionality has been achieved in the longer distance, we cannot guarantee error-free
operation over mentioned wiring length. We recommend reading Maxim’s 1-Wire tips at
http://www.maxim-ic.com/app-notes/index.mvp/id/148.
We guarantee proper operation only with Teracom 1-Wire sensors.
6.2.3. RS-485 interface
RS-485 is a standard for serial communications systems defined by Telecommunications Industry
Association (TIA) and Electronic Industries Alliance (EIA). Implementing the standard,
communication systems can be used effectively over long distances and in electrically noisy
(industrial) environments.
The maximum number of sensors (1-Wire or RS-485) connected to TCW210-TH is 8.
The device supports temperature and humidity-temperature sensors.
MODBUS RTU protocol specifies that address of the device should be between 1 and 247. The
user should take care of appropriate address settings.
For multi-sensors systems “daisy-chained” (linear topology) should be used:
TCW210-TH-R1.16- November 2022 Page 5
Interconnections are realized by UTP/FTP cables with RJ-45 connectors. The popular Ethernet
wiring standard ANSI/TIA/EIA T568B is used:
It is recommended to use standard patch cables for LAN networks.
Special attention should be paid on termination of the bus in the last sensor.
We recommend keeping total cable length up to 30 m, although the RS-485 interface works over
a much longer distance.
Attention!
Special attention should be paid on termination of the bus.
The last sensor in the chain should have a terminator installed on the free RJ-45 socket.
6.2.4. Network connection
The Ethernet port of TCW210-TH should be connected to 10/100 Base-T Ethernet hub, switch or
router.
For setup, TCW210-TH may be connected directly to the Ethernet port on a computer. The device
support Auto-MDIX and it is not necessary to use “crossover” cable, standard “straight-through”
can be also used.

IP address: 192.168.1.2, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1
Communication with TCW210-TH can be established by assigning a temporary IP address to the
computer. For computers with Windows OS assigning of IP address is made in “Local area
connection properties”:
TCW210-TH-R1.16- November 2022 Page 7
The 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 pop-up window will appear:
All TCW controllers connected to LAN can be easily found by the free tool “TCW discoverer”.
It is available for Win and Mac operating systems and can be downloaded from
www.teracomsystems.com.
7. Web interface
The WEB interface allows configuration, monitoring, and control. All pages are UTF-8 encoded.
For the WEB interface, the device supports HTTP only (HTTPS is not supported).
If the controller is properly addressing, login pop-up window appears.
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.
TCW210-TH-R1.16- November 2022 Page 8
The controller supports a few active session.
7.1. Monitoring
Monitoring page displays the current state of TCW210-TH. It has one data and four graphs tabs.
7.1.1. Data
The current state of TCW210-TH can be monitored on this page. There are two sections on the
page - оne for 1-Wire sensors and one for MODBUS RTU sensors.
TCW210-TH supports up to eight sensors. They can be connected to both interfaces in a random
ratio, settable in section “Sensors ratio setup” on Setup->Sensors page. By default, the number
of MODBUS RTU sensors are 4.
All detected 1-Wire sensors are shown in “1-Wire sensors” section. The sensors should be setup
in section “1-Wire sensors setup” on Setup->Sensors page.
Teracom 1-Wire temperature sensors readings are shown in the column “Temperature”, while
for dual sensors (TSH2xx) both column “Temperature” and “Humidity” are used. For dual sensors,
the parameter Dew point is calculated.
All MODBUS RTU sensors are shown in “Modbus sensors” section. The sensors should be added
and set up on Setup->Sensors page.
For every sensor, there are a description, value, and ID information. The description length is up
to 15 characters. Default descriptions can be changed in Setup->Conditions page.
Dual sensors (humidity-temperature) have the two parameters. For these sensors, Dew point
parameter is calculated automatically.
TCW210-TH-R1.16- November 2022 Page 9
The page can be automatically refreshed on an interval of 0 to 253 seconds. Zero means no
automatic refresh. This parameter is set in section Setup->System->Monitoring page automatic
refresh. By default, it is 1 second.
7.1.2. Graphs
Every graph page can display up to 4 parameters with up to 2 different dimension.
For every parameter different color can be set. There are a few checkboxes for display
modification.
Export of monitored parameters can be made from the page.
7.2. Setup
7.2.1. Network
The network parameters are set on this page.
The controller supports static and dynamic IP addresses.
It is good practice 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.
The “Hostname” is up to 15 characters. It is shown in the search results of TCW discoverer.
