6. EasyRX dedicated radio receiver
CAUTION!
EasyRX radio card is intended exclusively for the cooperation with EASY B231- DTM6 control unit produced
by DTM System. It should not be used autonomously.
6.1. General information
This receiver expands functional possibilities of EASY control unit to remote steering with DTM 433MHz
series remote controls.
6.2. Receiver card installation
It is the best to start the installation of the receiver from connecting the aerial to it. Next, receiver in the
form of the card - board with the edge connector should be pressed into the socket with the RADIO description on
a control unit board on the right-hand side (4 pins), side where buttons are placed towards the connector.
6.3. Subscribing remote controls to the receiver
The receiver has three identically programmed channels A, B and C. They are functional equivalents of
OPEN A, OPEN B and OPEN C inputs in the control unit). In case of the second and third channel we act the same
as during the programming of the remote control in the first channel (using the button of the second and third
channel respectively). In order to programme any button of the remote control in the first channel it is necessary
to:
- press and hold first channel A button
- when first channel A button is pressed, press
chosen button of the remote control
- first channel A diode flickers which indicates
success of the operation
- release the button
6.4. Terminals for aerial connection
In the brand new receiver an inside
aerial 170 mm long is connected to the
terminal. To increase the range of the radio
remote control, it is necessary to connect
outside stubby aerial. To connect the coaxial
cable of the outside aerial to the terminal (centre vein of the cable) and to the terminal (cable screen). In order to
achieve the optimum radio reach it is important to remember about:
- negative influence of the receiver with energetic devices and metal objects in the aerial neighbourhood,
- negative influence of radio interference from other sources,
- negative influence of high-density housing, wet or reinforced concrete walls.
- shorten range with used remote control battery
- increasing range with increasing height of receiver aerial location
6.5. Remote subscribing of new remote control
The radio EasyRX card has a program enabling simple subscribing of the new remote control for the user
without the need for the access to buttons.
This function is only useful when you have a
remote control already subscribed in the
memory. To subscribe new remote control in
this way it is necessary to proceed according
to fig. 6.
CAUTION!
Possibility of adding remote control
without the access to the control unit
dramatically decreases the level of
security against third parties.
