SD Data Logger

Bought an SD data logger for Christmas for my current project.· However, I am a programmer by trade, not an EE . . . So, I have no idea how to start connecting the wires.· Here's my current status:· I have the Data Logger attached to the body of the bot with the 3 wires dangling loose.· The 3 wires are the Serial, +, Gnd.· Below is the description of the pins·included with the data logger:

Serial
Serial In/Out connection to the SD data logger.
The data logger allows either 19,200 baud or
2400 baud depending on jumper JP1. If the
jumper is on, then the baud rate is 19,200. If the
jumper is off, then the baud rate is 2400. This
pin is used for both sending and receiving data.

+
Supply voltage input to regulator. Vin may be
between 3.6 and 7.5 volts. This source must be
able to supply 50 milliamps of current.

Gnd
Power supply and serial ground. This MUST
also be connected to ground on the device
sending the serial data to the module.

Is it possible for someone to give me simple instructions on how to attach properly?· I'm trying to attach this to P15.· Digital photo of this connected to a BOE Bot would help GREATLY.

Thanks!

    + goes to the positive terminal of your power
    Gnd goes to ground
    serial goes to a pin on the BS2 that you plan to communicat with.

    i am going to make the (expletive)umption that you have the SD Data Logger from Hitt Consulting. Attached is a picture. It is pretty straight forward. using a parallax LCD extension cable or similar. http://www.parallax.com/detail.asp?product_id=805-00012

    Attach one end to the boebot servo header location 15 and attach teh other end to the SD Data Logger.


    The Baud rate is set for both directions,· Your choice between the two speeds.

    Enjoy.

    Brian, I guess the language filter got a little carried away on your post. Ha Ha Ha

    The easiest connection is how Brian has shown, just don't forget to put the switch in position "2" to power the data logger.

    Awesome, Thanks!· I feel like an idiot now because it was so simple.· Tested the data logger and everything works!· I'll post my project when I finish.
