Those familiar with RS232 will know that the standarddefines how RS232 lines should be driven electrically:what they are called, what information they carry andeven the connectors and pin numbers to use. RS422and RS485, by contrast, define only the electricalcharacteristics of the driver.

Advantages of RS485 and RS422
RS485 and RS422 drive lines in a differential fashion:two wires are required for each signal. If you wish totransmit four signals then eight wires are needed. Thefigure below shows a single RS485 / RS422 signal beingtransmitted. To transmit a logic 1, line B is high andline A is low. To transmit a logic 0, line B is low andline A is high. The advantage of this arrangement isthat signals can be transmitted faster and over greaterdistances than is possible with a single wire.
Diffences Between RS422 and RS485
In both RS422 and RS485, one driver can drive manyreceivers. In RS485 each driver can be switched offallowing multiple units to send data over a singlepair of wires. This is not possible in RS422. Thisextra feature causes extra problems for RS485 units.Other differences are small so hereafter I will referto units as RS485 but the remarks apply to RS422 also.Interface units often describe themselves as RS422/RS485because a RS485 unit which is not using its extracapability is RS422 compatible.
RS485 Wiring Arrangements
When instruments are described as having an RS485 interfacethis tells you nothing for sure about the signals beingtransmitted. Usually though only the Transmit Data (TX)and Receive Data (RX) of a normal serial port are convertedto RS485 or RS422. The other signals of the serial port arenot used. Three arrangements are commonplace: Write only,4-wire (full duplex) and 2-wire (half duplex).
Write Only System: Sending Data Only
In this arrangement the computer sends data out over asingle RS485 pair of wires to many instruments. It neverreads any data back. An example of this is the remotecontrol of CCTV cameras. The operator can send outmessages to move the camera. His feedback is the TVpicture so no return data is needed. This requiresonly conversion of the RS232 TX signal to RS485.
Full Duplex System: Sending and Receiving Data over 4 Wires
Full Duplex means that data can pass simultaneouslyboth to and from the instruments. This requires4 wires - one pair to Transmit and one pair toReceive. The computer alone controls the TXtransmit line. It sends out a message which includesan Address. The addressed instrument alone replies bydriving the RX line.
This does mean that all the connected instruments mustuse the same software protocol - otherwise there willbe confusion as to which instrument is being addressed.A simple conversion of RS232 to RS485 will sufficefor this arrangement and no special demands aremade on general purpose software such as ComDebug.
Half Duplex System: Sending and Receiving Data over 2 Wires
Half Duplex means that data can only pass in onedirection at a time. In this arrangement both TXand RX signals share a single pair of wires. Thiscan save in installation costs.
The computer drives the lines to send out itsrequest message but must turn its driver off toallow the instrument to reply. This is the trickybit. Many RS232-to-RS485 converters recruit theRTS line of the serial port to switch theRS485 driver On and Off. However Windows has nevermade more than a half hearted attempt to supportsuch an arrangement.
The multi-tasking nature of Windows means that itis always difficult to make actions occur at exacttimes - in this case there can be a significantdelay between the request being sent out and thedriver being switched off. If the instrument startsits reply before the switch-off then the start ofthe reply will be missed. Instrument manufacturersare forced to find their own solutions to thisproblem. This may include special software, specialhardware or both.
In recent years most Serial Ports have beenimplemented as USB-to-Serial arrangements. Theseunits always include a microprocessor and this canperform the task of controlling the RS485 driververy well. If you need to implement a 2-wireRS485 system you should always obtain a USB-to-RS485converter that advertises this special feature. Anexample type that we use is Moxa 1130. This unitautomatically switches off the driver when thereis no more data to send. Such a unit can workwith general purpose software such as ComDebug orHyperTerminal. Be aware though that it may not workwith the special software supplied by instrumentmanufacturers which may assume a particular RS232-to-RS485 converter and may produce errors whenused with any other unit.
Preventing Voltage Reflection
When a signal is sent down a cable there is alwaysa reflection voltage which returns up the cable.This reflection is bigger as signals' edges getfaster and lines get longer. It can be minimisedby terminating the ends of the line with thecharacteristic impedance of the system. This is120 ohm for RS485.
Ideal RS485 Wiring
Ideally an RS485 system consists of a singlelinear cable (no branches) with 120 ohm resistorsconnected across the 2 wires at each end of thecable.
RS485 can handle speeds of over 10 Mbits persecond and line lengths of over 1 km. If youare operating anywhere near these values you mustarrange your wiring close to the ideal.
For many applications where baud rates are slow(say 9600 baud), and lines are only tens of meterslong, this is not essential. The wiring requirementscan then be relaxed to allow cables to run in stararrangement from the computer and the terminatingresistors become optional.
Line Pull Ups: Avoiding Serial Errors
In many RS485 multidrop systems there are timeswhen no unit is driving the RS485 lines. They canthen go to any voltage and may produce serial errors.To avoid this it is often necessary to fit resistorswhich pull one line high and the other line low puttingthe line into the passive state. The RS485 convertersusually include such resistors which can be connectedif needed.
RS485 Signal Names: Caution Required
You will find that your RS485 signal names for a linepair are either A,B or +,-. In an ideal world you wouldsimply connect A on the computer to A on the instrument.However these names are not consistently applied bymanufacturers and you may need to connect A on thecomputer to B on the instrument.

Note- the commonly used DRV8825 boards (often purple) using the TI DRV8825 chip have a different motor pin out than the A49xx and similar. The silkscreen of A1 B1 B2 A2 matches the A49xx boards. The DRV8825 uses the format of A1 A2 B1 B2, so the coils should be wired together in pairs. This leads to some confusion.
Further, for this user, the nomenclature of 1A 1B 2B 2A was somewhat confusing at first. It is more commonly annotated as I have written it previously (A1 B1 B2 A2) or as A and A-bar (an A with a bar over the top) for A1 and A2 respectively.

The following confusion was encountered with Rumba (board blue LKDR20150602, also see #RepRapDiscount_Smart_Controller) and Smart Controller from kickstarter 'Prusa i3 with Diamond Hot end': Rumba-boards small white triangle (pin 1 indication - visible if no plug) is inconsistent with the cable red-line indicating pin-1. And to further 'confuse you', the 'Smart Controller' plug exp1 must NOT go to exp1 - it should go to exp2 on Rumba. If you orient the plug on Rumba pin1-to-cable-pin1 - and plug exp1-to-exp1 and exp2-to-exp2 you will get the following error meassage when surveying the serial port (via USB on Rumba e.g. with Arduino IDE 1.0.6) (the exact message might differ):

RUMBA Wiring
Wiring plan based on available information, may contain wrong information ! / recheck necessary.
A different version of RUMBA has a separate COM port 4-pin block (RX/TX/GND/+5) interior of the 16U2. Need picture and docs.
ATX power supply (controlled with RUMBA)
Set the power jumper in 'stand alone' position
Connect GND from your ATX power supply to USB header Pin1 (where the black triangle is)
Connect 5 VSB from your ATX power supply (+5 VDC Standby Voltage) to USB header Pin4
Connect GND and PS ON (Power Supply On) from your ATX power supply to PS ON header, polarity doesn't matter
You'r now able to switch your power supply on and off via gcode or smart controler. With ATX +5 VDC Standby Voltage RUMBA is always powered on even if the power supply is turned of via RUMBA.
FAN0
Can be activated with the usual M106 Sxxx and deactivated with M107 (or M106 S0)
FAN1
Could be activated by using Mcode : M42 P8 Sxxx (0 < xxx < 255)
Marlin Firmware Configuration
Change in Marlin Configuration.h:
if you are connecting the Reprap discount smart controller uncomment this line:
If using Mac OS X as host:
To flash your firmware of choice with the Arduino suite you have to select 'Arduino Mega 2560 or Mega ADK' as Board.
This following is an example only! Most likely your firmware of choice will have support for RUMBA built in
As of Marlin v1.0.0 pins.h contains the below suggested definitions, you should only need to change Configuration.h as mentioned above.

Troubleshooting
USB connection
This section is 'Work In Progress'.
Symptoms
Without any reason, the USB connection to the RUMBA is not possible. When connecting the USB cable to the computer, the operating system does not see any device. If the board is provided with a SD card reader, printing with a SD card is still possible.
The RX/TX lights may be stuck on and may/may not flicker when the host is polling the RUMBA over USB. Anecdotal comments point to this happening on a cold startup after a session of successful printing, usually from the day/night before.
Note-- A single user reports that disconnecting the LCD (while trying to upload firmware) solved the problem. This user believes this to be due to the power draw on a 'USB Powered' board and the supply limitations of USB of 1A of 500mA (depending on the version, etc). Symptomatically, it was noted that the LCD Screen contrast was diminished, and the measured voltage was 3.8 on the 5V rail, leading to a suspicion of under-volting. In this user's case, entering DFU mode was not possible, likely because the voltages were not reaching the expected High digital level. Before proceeding with the following, try simply disconnecting the higher power devices that are running at this time (motors and the heated bed should be off by default while trying to flash, but other peripherals perhaps..)
Correction
First, be sure that the problem is not due to a bad position of the power jumper. The problem could be caused by the USB2Serial firmware. Then, you should flash the firmware following these steps:
- Set the power jumper in 'USB powered' position.
- Place a jumper slightly on the two pins pointed by the white arrow (see picture below). (These are the Ground and Reset pins of the ISP programming header for the ATMega16u4 chip that handles the USB communication.)
- If the board is not mounted on your printer, place it on a clean, dry and insulated surface.
- Connect the USB cable on the board, and connect it on your computer
- Remove the jumper (be careful not to make short-circuit, do not use metallic tools). The TX and RX leds are flashing: the board is now in DFU mode.
Reset pins:
Jumper locations:
If you are running Windows, you can now flash by doing this (Tested on XP, should be fine on higher versions):
- Download and unzip File:RRD-RUMBA ATmega16U2 USB2Serial.hex.zip on your home folder.
- Download and install FLIP from AMTEL.com (Version 3.4.n7 a the time I'm writing this).
- Provide the DFU driver to windows, it should be located in the usb folder of your FLIP installation.
- Once the driver is properly installed, run FLIP.
- Select device ATMega16U2.
- In the HEX file frame, select, if not done yet, FLASH (If done, it should display 'Select EEPROM' in the button.).
- Select File -> Load Hex File --> point it to the download hex file (from the first step).
- In 'Operations Flow frame', ensure that checkboxes 'Erase', 'Program' and 'Verify' are selected.
- Click RUN.
- You can now disconnect and reconnect the USB cable, and everything should be back to normal.
If you are running Linux or Mac OSX, you can now flash the firmware by doing this:
- Download and unzip File:RRD-RUMBA ATmega16U2 USB2Serial.hex.zip on your home folder.
- Note: Make sure you get the latest version of the Hex file, i.e. . . Arduino-usbserial-atmega16u2-Mega2560-Rev3.hex, the DFU method didn't work on my Mac, I used a Pocket AVR Programmer and the ver3 hex, it worked like a charm.
- Install the software dfu-programmer. You must have the version 0.5.5 or above (Ubuntu 13.10 or higher).
- Mac users can install via Homebrew
- With root privileges (or sudo command), execute this command line to flash the firmware:
- You can now disconnect and reconnect the USB cable, and try to connect your host software to the board.
- Another way to verify the fix is to use the 'lsusb' command
Install lsusb:
