1 Transmitter.
•
1 Receiver.
•
2 Antennas with their connectors (they can be different).
•
1 User Manual in the web www.itowa.com
2.1. OPERATION
The general operation of the LEVEL ITW sets is the following: each time a change of state of
any of the digital inputs of the transmitter takes place, this variation is wireless transmitted to
the receiver to activate /deactivate the relay output corresponding to that input, that means,
the digital input nº 1 corresponds to the relay output nº 1, the input nº 2 with the relay output
nº 2 and thus to complete all the signals.
In models with analogical signals, in each transmission the value of the analogical signals is
refreshed, due the variation of them is not being sent continuously.
In addition, every 5 minutes the transmitter sends the status of the inputs to refresh the
information to the receiver and check the communications.
.
2.1.1. DIGITAL LEVEL ITW OPERATION
The DIGITAL LEVEL ITW has some led to indicate the status of the corresponding inputs or
outputs, as well as a possible communication failure, and the correct performance of the link
and the power supply.

2.2. LEVEL ITW TRANSMITTERS
The transmitter function is to transmit any variation in the state of the digital inputs, and time
to time send a signal with the current state of the digital and/or analogical inputs to refresh the
information to the receiver, on this way it is also verified there is not communication failure
between the equipments.
2.2.1. INSTALLATION OF THE TRANSMITTER

5. CHANGE OR FREQUENCY
In case that the system does not link correctly due to the interferences in the programmed
frequency band, the working channel can be changed manually.
NOTICE: THE CHANGE OF WORKING CHANNEL MUST BE DONE IN THE
TRANSMITTER AND IN THE RECEIVER.
YOU MUST MAKE SURE TO ASSIGN THE CORRECT FREQUENCY BAND
ACCORDING TO THE RADIO MODEL OF YOUR SYSTEM.
The change of frequency can be done indistinctly, when the system is working or without
power.
It is recommended to start the change of frequency on the receiver system and after on the
transmitter. In case that the systems were working, the change will be done after 10 seconds
approximately.
To make the change you must open the system and to log into the changing frequency
control board.
ITW LEVEL
USER MANUAL

FREQUENCY BAND:
The change of the frequency band is done through the configuration of a jumper, as you can
see in below picture.
Be sure that the frequency band is the one that corresponds to the model of system you are
handling, BAND -869 MHz / 406 MHz / 411 MHz If you select band 869MHz for a system
manufactured to work at 406-411 MHz band or vice versa the system WON’T work.
WORKING CHANNEL:
The change of the working channel is done through a rotary switch of 10 positions (0/9). Each
position has assigned a definite working channel, as you can find in the below configuration
table.
Table 5.1
Be aware to assign the same frequency band and channel to the transmitter and to the
received.
Remember if you have a system in the 406-411MHz band, installed in Spain, you must
Apply for a licence to the DGTel and once assigned the frequency and working
channel, legally, you cannot modify it.
