RS232-ADPTM Serial RS-232 Adapter User Manual
This RS232-ADP board is a high-speed
RS232 Serial UART to TTL level
converter module. It is allow you to
connect the serial COM port on your
computer directly to the module. The
module then translates RS232 level to
TTL level on the TXD and RTS lines.
Also, translate TTL level back to RS232
level on RXD and CTS lines.
This board features innovations that set
it apart from other RS232 Adapter
boards. Innovations feature like RXD
and TXD status LEDs. Quick and easy
connect that you can plug directly on to
the breadboard. The board is small and
compact in size 1.50 x 1.25 inches.
The TX and RX pins from the RS232ADP can be connected directly to RX
and TX pins of your preferred 5V logic
microcontroller. You only need to supply
5VDC to the board.
The RS232-ADP board is perfect for
embedded systems that require a serial
connection to a computer. The board
attaches directly to the computer COM
port via a serial DB9 cable. The PC
serial port transmits and receives signals
at +/-12V while TTL devices including
microcontroller operate at +5V and
GROUND. In order for you to interface
between the two, you’ll need this
interfacing circuit.
