Connecting the Baron 4WD motors to the ROMEO

There are four motors but only connectors for two motors on the ROMEO. I assume that one set of connectors goes to the right motors and the other set goes to the left motors??? And each motor on each side should be connected in parallel??? Also, there are only encoders for two motors. I placed them on the back motors. How will I control the speed and rotation of the front motors? Or am I missing something?
As for programming it, I saw this page:

And I initialize with this
Stepper_Romeo myStepper(200,7,6,4,5);
The first value stands for the total number of steps of a revolution for this motor. The others define the typical output pin on the Romeo.
For the Baron 4WD, what is the correct number of steps for one revolution with the motors that come with the kit? And what pins are the 7, 6, 4, 5 referring to? I know they are pin numbers on the board, but I have no idea what is connected to them in this example. Four pins for one motor? Finally, this example is for one of the four motors, correct? So I will want to create four instances of Stepper_Romeo, one for each motor, correct?
By the way, I am the same user as MrGibbage. I tried logging in again and it said my password was invalid, even though I was able to log in last night. I tried resetting my password, but I never got the reset email. In fact, I never got an email after registering both last night and this morning. Does the forum software have issues sending emails? And yes, I have checked my spam folder.

2013-06-07 14:05:07 Never mind. I found another wiki that explained it all

2013-06-07 13:04:23 Cool.
But, back to my original post, please explain the programming of the motors. The wiki states to initialize a new object, use
Stepper_Romeo myStepper(200,7,6,4,5);
and then goes on to explain (quote)
The first value stands for the total number of steps of a revolution for this motor. The others define the typical output pin on the Romeo. (end quote)
So, is 200 the correct value for the motors that are supplied with the kit? And what output pins do I use? What are the output pins used for with regards to the motors? And how do I differentiate between the left and right motors? What is the code if I want just the left motors to run, or the right motors, or both?

2013-06-06 22:24:41 yup, encoders are useful when needing a function that requires accurate movements. Or for example mapping a place with sensors by measuring distance covered and so on..
But for moving the motors you don't need the encoders.

2013-06-06 06:27:56 Ohhh... so the idea is that I don't need to use the encoders to just move the rover around. The driver on the board takes care of it. But if I want feedback of the wheel position, then I can use the encoders to get that.

By the way, how do I connect the encoders to the ROMEO?

Hi
You can refer to this encoder's sample code. They should be the same. You can connect to ROMEO digital pins according to the code. ;)
