Information for users

This equipment has been tested and found to comply with the limits for a Class B device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference in a residential installation. This equipment

generates uses and can radiate radio frequency energy, and if not installed and used in

accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the

user is encouraged to try to correct the interference by one or more of the following

measures:

•Reorient or relocate the receiving antenna

•Increase the separation between the equipment and receiver

•Connect the equipment into an outlet on a circuit different from that which the

receiver is connected

•Consult the dealer or an experienced radio/TV technician for help

Caution: To satisfy FCC RF Exposure requirements for mobile and base station

transmission devices, a separation distance of 20cm or more should be maintained

between the antenna of this device and persons during operation. To ensure compliance

operation at closer than this distance is not recommended. The antenna used for this

transmitter must not be co-located or operating in conjunction with any other antenna or

transmitter. No other antenna may be used with this equipment other than the PCB

antenna supplied with this equipment.

Caution: To satisfy FCC RF Exposure requirements for mobile and base station

transmission devices, a separation distance of 20 cm or more should be

maintained between the antenna of this device and persons during operation. To

ensure compliance operation at closer than this distance is not recommended.

The antenna used for this transmitter must not be co-located or operating in

conjunction with any other antenna or transmitter. No other antenna may be used

with this equipment other than the PCB antenna supplied with this equipment.

1.2 Hardware Features

Our range of IWT wireless transmitters are available for a wide range of input

types.

The IWmAT 4-20 mA Transmitter has been designed to accept an input from an

existing 4-20 mA signal and transmit the value to one of the IWR range of

receivers.

Please note that the IWmAT does not power the 4-20 mA loop, if powering a

standard 4-20 mA wired transmitter is required please use the IWTxT unit

instead.

IWTaT Series

Wireless Temperature & Humidity Operating Manual

Depending on the receiver used, the value can be outputted as either a 4-20 mA

or 1-5 V dc signal, displayed and logged on a PC, output as a Modbus RTU or

TCP/IP register, or transmitted to a remote server using MQTT messages. The

range of receivers available is shown in the table below.

Receiver Type

Features

IWR-1

1 off 4-20 mA or 1-5 V and 1 off Relay Output

IWR-5

5 off 4-20 mA or 1-5 V and 1 off Relay Output

IWR-USB

Connects to any PC for data display and logging

IWR-PORT

Stores data from IWT transmitters as Modbus

Registers

IoT-Gateway

Stores data from IWT Transmitters & sends it to

remote servers using MQTT packets

The IWTaT and IWTRhT transmitters work within the ISM license-free

2.4 GHz bands. Ranges of up to 500 m are possible using the standard

transmitter and receiver unit with the optional 3dBi antenna giving a range of up

to 750 m.

The transmitter is powered by a primary 3.6 V lithium cell and care must be taken

to insert the battery in the correct polarity.

UNPACKING

The instrument should be carefully inspected for signs of damage that may have

occurred in transit. In the unlikely case that damage has been sustained, DO

NOT use the instrument, but please retain all packaging for our inspection and

contact your supplier immediately.

3 PRODUCT IDENTIFICATION LABEL

The unit delivered should be carefully inspected to ensure it is suitable for the

application required. Detailed information on the product is included in the

identification label and the user manual.

Please ensure, in particular, that the input range of the IWT is suitable for the

intended application and that the IWT unit will not be subjected to temperatures

greater than those specified in this manual.

4. INSTALLING/CHANGING THE BATTERY

A Lithium 3.6 V battery is included inside the IWT transmitter. The battery may be

changed at any time, but care must be taken to install the battery with the correct

polarity.

After the battery has been changed, the unit should be switched on using the

yellow slider switch SW3 and then the pushbutton SW1 should be pushed and

held for 5 s. This is to ensure the battery life count is reset correctly when a new

battery is installed.

The internal red LED will flash 5 times to indicate this procedure has been carried

out successfully.

The battery life is determined by the rate the transmitter sends the Temperature

value to the receiver, this update rate can be selected using Dip Switch 1 and the

default value is 10s.

Please dispose of all batteries as specified by the legislator according to the

Closed Substance Cycle and Waste Management Act or country regulations.

! WARNING!

5. SETTING UP THE IWT WIRELESS TRANSMITTER

The IWT instrument is shipped in a default configuration which allows the unit to

connect with any default IWR receiver unit and transmit the measured signal

every 10 s simply by switching the unit on using SW3 on the internal circuit

board.

If a different update rate is required, or a different network frequency channel is

required these parameters can be selected using DIP Switch 1 as detailed below:

! WARNING !

MAKE SURE THE CORRECT

BATTERY POLARITY IS OBSERVED!

Switches 1, 2, 3 & 4 select the RF Network the IWT will transmit on. The default

network for both the IWT transmitter and IWR receiver is network 1.

Switches 5, 6 & 7 select the Transmission rate of the unit. This effectively sets

how often the measured value is sent to the receiver.

At 1 and 5 second rate, a power save option is available (on by default) that

changes the transmit time to every 30 seconds if the IWR is switched off or out of

range for more than 3 minutes. This option can be changed using the IWT-SET

program.

Switches 8, 9, and 10 set the Channel Number of the transmitter. This is used

with the 5 channel receiver unit (IWR-5) to select which IWT wireless transmitter

is linked to which

4-20 mA or 1-5 V dc output channel.

Channels 1 to 128 can be used with an IWR-USB, IWR-PORT, or IoT Gateway

receiver. The channel number can be changed using the IWT-SET PC

configuration software if switches 8, 9, and 10 are switched to the on position.

The IWT transmitter is now set up and ready to be used. Install the unit where

required, wire the appropriate input into the IWT as specified below (if there isn’t

an integral sensor), and switch the unit ON using SW3. Pushbutton switch SW1

can be pushed to force the unit to transmit its current measured value. A red LED

1 will flash once when the transmit button is pressed and flash a second time if

the transmission has been received and acknowledged by an IWR receiver unit.

If the unit has transmitted successfully, the output of the connected receiver unit

will output a value reflecting the signal level being measured.

6. TROUBLE-SHOOTING GUIDE
