Re: pic: 1501 Electronics Board



Sorry it took so long, i will explain this real quick before going to bed.

The box on the board is just a conjunction box taking the program, the breaker panel, the tether, the camera TTL, and the remote Rest and Program buttons and putting them into a DB25 cable. There is a switch on the box to go from Programming mode and feedback to breaker panel feedback.

There will be two external boxes, one will be on the robot and will have the reset and program buttons and the Camera TTL on and off. While the other is going to be built in to the OI Controller Station. From there not only will we be able to have a Remote Reset and program button, camera TTL on and off switch, but we will be able to leave the laptop at our OI station and control everything during practice mode and have it tethered while going through one cable. Otherwise having a tether cable, a program cable, and having to keep putting the robot into program mode and disconnecting and reconnecting the TTL chip on the board all the time gets rather annoying.

Our DB25 Cable is 25 feet long, and we took into consideration that the RS232 data can only travel about 50 feet.

I will be posting electrical schematics hopefully soon.

P.S. This board has changed since this picture was taken i will take a final picture before we pack our beauty up in the crate.
