TDA7210V Remote Control Rx-Board
Step-by-Step Quick Start Guide
Please follow this step-by-step approach when you start up your TDA7210V
PMAfob remote control demo for the first time:
Check the placement of all jumpers on the board. By default the jumpers marked
MSEL
and
CSEL
must be in closed position. The power down mode selection jumper
marked
PWRDWN
must be closed in position
+V
. All other jumpers or test pins on
the board must be left in open position (except the power supply selection jumper
5V/7-15V
– see below). See the picture on the right where all closed jumpers are
marked.
Connect the antenna to the SMA-connector marked
RF IN.
This application operates
in the 434 MHz frequency band. Therefore, antennas with red marking are suitable.
Connect a suitable power supply to the TDA7210V Remote Control Rx-Board. There
are two alternatives:
Regulated: Connect a regulated DC supply voltage of +5.0V to the screw
terminals marked
GND
and
5V
. In this power supply mode the related
jumper must be placed in position
5V
.
Unregulated: Connect an unregulated DC supply voltage in the range
between 7.0V and 15.0V to the screw terminals
GND
and
7-15V
. In this
power supply mode the related jumper must be placed in position
7-15V
.
Switch on the power supply.
Press button
S1
to activate the receive mode. LEDs
DL1
and
DL2
will signalize the
receive-ready state.
Upon delivery of the kit the enclosed PMAfob remote controller is already set to the
correct protocol mode for this demo. By pressing buttons on the PMAfob related
channel LEDs (
CH1…CH5
) on the TDA7210V Remote Control Rx-Board will change
their state.
Note: The PMAfob remote controller supports different protocol modes. This demo
requires the mode
XTEA-Frame/no encryption
which is already configured upon
shipment of the kit. The protocol mode may be changed by removing the battery from
the PMAfob or accidently by holding buttons down longer than 3 seconds. In case your
TDA7210V Remote Control Rx-Board does not react to any remote control commands
anymore, follow these steps to reactivate the right protocol mode:
Open the PMAfob housing and remove the battery for longer than 5 seconds. Re-
insert the battery again.
Hold down button
CH5
for longer than 3 seconds.
Hold down button
CH4
for longer than 3 seconds.
Now, protocol mode
XTEA-Frame/no encryption
is re-established and the demo shall
operate as expected.
Find more information about PMAfob protocol modes in the PMAfob User Guide.
Early versions of PMAfob delivered with other kits may not support the protocol mode
XTEA-Frame/no encryption
. These may be re-programmed with newest PMAfob
firmware (see
www.infineon.com/PMAfob
) for full compatibility with all applications.
