In the serial settings, make sure you have 8 bits, 1 stop bit, no parity and no flow control before you connect. Now all you need to do is to fire up Putty, change connection type to РІР‚СљSerialРІР‚Сњ, enter your serial COM port, and then access the РІР‚СљSerialРІР‚Сњ settings (red highlight on the right image). If everything looks OK, power up the Pi and plug in the RS-232 cable.

If youРІР‚в„ўd like to talk to serial peripherals from Pi instead, RX/TX wires need to be reversed.Р”В«efore you connect the Pi, check with a voltmeter that GND from Raspberry Pi and GND from RS-232 do not differ from each other too much (a few millivolts is usually OK), otherwise you may risk a ground loop and damage to your equipment! Using Putty to connect to Raspberry PiР”Р„fter youРІР‚в„ўve made all the connections, double check the connections once more, maybe even check the this full sized photo.

Update: The RS-232 connection diagram is from the side youРІР‚в„ўd solder the wires from (РІР‚Сљback sideРІР‚Сњ of the connector), and wired so you can connect a PC USB serial adapter to Raspberry Pi. The red, brown and blue wires go to the RS-232 port РІР‚вЂњ see the illustration on right for connections on this side. The orange, white, green and black wires come from Raspberry Pi and provide power and data lines.

IРІР‚в„ўm not going to cover the internals in detail this time, please either refer to the datasheet or my previous tutorial discussing this same chip.Р”Р„bove you can see one rather compact way to wire the MAX3232. It uses a few capacitors to deliver true +-12V RS-232 signalling on one end, and 3.3V signalling on the other. The MAX3232CPE is very much like itРІР‚в„ўs 5V sister model, MAX232. GND is also needed, and the two UART pins, TXD and RXD. WeРІР‚в„ўll use the 3.3V pin for power РІР‚вЂњ the draw should not exceed 50 mA, but this should not be an issue, since MAX3232CPE draws less than 1 mA and the capacitors are rather small. The connections on Pi side are rather straightforward. Just make sure it doesnРІР‚в„ўt internally short any of the connections РІР‚вЂњ use a multimeter if in doubt! I had a short 2Р“вЂ”6 pin extension cable available and used that, but an IDE cable and other types ribbon cable work fine as well. The last item is needed to connect male-male jumper wires to RaspPi GPIO pins. 5 x 0.1 uF capacitors (I used plastic ones).MAX3232CPE or similar RS-232 to 3.3V logic level transceiver.Serial port in your PC or USB to serial -adapter.

So in this short tutorial, IРІР‚в„ўll show you how to use a MAX3232CPE transceiver to safely convert the normal UART voltage levels to 3.3V accepted by Raspberry Pi, and connect to the Pi using Putty.

Even РІР‚СљTTL levelРІР‚Сњ serial at 5V runs the same risk. However, normal UART device communicate with -12V (logical РІР‚Сљ1РІР‚Сњ) and +12V (logical РІР‚Сљ0РІР‚Сњ), which may just fry something in the 3.3V Pi. These pins also include an UART serial console, which can be used to log in to the Pi, and many other things. In addition to the audio, video, network and USB connectors, the Raspberry Pi also has 26 GPIO pins.
