Switch SSC-32 from Bot Board II or PC control

Here is a way to easily switch from the Bot Board (TTL) or the PC (DB9 RS232) for communicating with the SSC-32.

Don’t forget to mention that the max baud rate can be 38.4k… So long as you set the baud rate of the PC’s com port (which is usually defaulted at 115k), you don’t have to fiddle with the baud rate jumper everytime you switch the cable from the bot board to the ssc-32

:smiley:

This is a great way to set up a bot for programming. Currently I have to remove the the cap screws to get access to the jumpers and switch everything around for PC/ABB comms.

Great idea.

Hi folks, I got a couple of questions. From what I understand this is connections diagram hence all the powering options from this topic (I`m doing the one on Image 3):
lynxmotion.net/viewtopic.php?t=2401
Still apply. Right?

And my second question; when switching between modes, would I have to unplug the serial cable from the SSC 32 and plug it to the Bot Board?(If I want to program the Bot Board that is)

Thanks guys :slight_smile:

Yes this really has no effect on how you wire the boards for power.

This diagram is for changing what is sending data to the the SSC-32. It’s either the PC or the Bot Board. For programming the Bot Board you would need to move the cable.

Thank you very much Robot Dude! I`m all set to go :smiley:

PS. I really love your site and products. You guys are doing a great job!

Hi Jim,

your Image doesn’t show any jumpers. They are not necessary in this configuration?

Because this is only illustrating the serial comms we purposely removed all other jumpers from the drawing. In other words all the other jumpers will need to be set for the application it’s to be used for.

Just to add a little too this… I used a DIP switch and connected it to the baud pins, then I took the last switch and tied it to the first pins on the left side of the connector so that you can turn them all off, and the last one on, and it ties them together to do the force firmware upgrade
I know this jpg is awesome… you’d never believe I do visual effects for a living lol

Hi Jim,

I use this connection!!! Great!
Now, for my ARM, I wont to create a little console in wood with all switch: Switch for BBII power, switch for servo power and this new switch. It’s possible use a LED to indicate the ON/OFF state for every switch?
Thx

You would have to get a 3 pole 2 throw switch. Then use the extra pole to turn on one of two LED’s. The existing 2 pole 2 throw switch carries serial coms, so you can’t just stick an LED on it.

Thank you Jim.
But, I will connect a pole of the LED in the free pole of the switch and the other one?

Something like this…

Thanks djsfantasi!!!

I must change the switch?

But if I connect a LED to a plug for the servos on SSC-32 so that lights when the switch that powers the servos is ON
and one on BBII when the power is ON?
For example:

The switch doesn’t switch power; it directs the serial communications to either the SSC-32 or the Bot Board. Power may be supplied to both devices regardless of this switch setting. In your last diagram, power to the boards are from the switches on the left.

What the indicator I have sketched does do is indicate whether serial communications is going to the SSC-32 (LED is lit) or the Bot Board. The unused connector may be used with a different color LED and resistor, so that each color represents communication to a specific device.

Ok I understand!!! So there’s no power in the “COMM Switch”?

Correct, there is no power in the “Comm Switch” in the original diagram. It is only used to direct the serial communications. When we get a new switch as in my diagram, the extra contacts are used to bring power only to LEDs to indicate which serial destination is selected. The original switch was a double throw douple pole (DPDT) switch. To use the indicator LEDs, you would need a 3PDT (3 pole double throw) switch. [size=85](A 4PDT would work if you have one; you would just have extra contacts…)[/size]

Ok!! Thanks!

The following diagram is possible? (Please no laugh for my resistor design!! :blush: )

Hi,

I believe you’ve to turn the diode (catode against ground). Beside that it should work fine.

OK!!! :laughing:
