I’ve a biped scout with microcontroller SSC-32. The problem is that the microcontroller doesn’t get the comands from the computer(the LED-light D1 is constantly on and the motors are on(the robot can stand) by they are not moving). I tried another microcontroller , new cabel for conection with the computer and new battery, but the robot still doesn’t move.
Does anyone had this kind of problem and do you know a possible solution to this problem?
Please help soon.
Thanks for the help 
Hi Lost,
We will need a lot more information to try to help. If I read this right, you have a scout with an SSC-32 on it. Is there any other microcontroller such as a Basic Atom Pro or the like on it as well or are you simply trying to control the scout from a PC?
Are you following any of the tutorials for this? If so which one and what step are you up to?
If you are controlling it from a PC what program are you using on the PC? What are the jumper settings set on the SSC-32? For which baud rate? Does this match the baud rate on the PC?
What types of batteries do you have connected to the robot? Has it been charged?

Hi Kurt,
My scout has only an SSC-32 on it.
I’m using Lynxmotion Visual Sequencer v1.16 for SSC-32 to control the scout from PC. The baud rate is ok and the batteries are HFR-6V AA1600 and are charged.
I was able to move the robot form PC, i was trying to make it walk and it was all perfectly fine. But once after charging the batteries, the robot could only stand(the servos where on) but didn’t recognize any of the commands
from the Sequencer(didn’t move any of the servos). I tought that the problem was the SSC-32 and I replace it with the spare one, but all remain the same. Then I changed the battery and no luck with that too.
Is this enough information about my problem?
Thanks for the quick reply.

Hi again,
The first two things I always check in cases like this is power and communications. So First if you look at your current ssc-32 and the manual: lynxmotion.com/images/html/build136.htm#ssc32lay
It sounds like you only have one battery hooked up. Do you have the VL=VS jumper in place (5 in diagram), likewise VS1=VS2(3). Are you setup to do communications through the 9 pin connector. That is are both jumpers in place at #14. What baud rate is set at #9.
You say that the LED #11 stays on? If so then it sounds like it is not getting any information from your PC. What type of serial cable are you using? Is it a “Real” RS-232 port or are you using an USB to serial cable? If so which one? Have you tried rebooting your PC? Have you verified that SEQ is set for the right COMM port and that the right baud rate?
If you startup Visual sequencer with the RS-232 cable connected from your pc to the SSC-32 card does it show up as connected? Does it show you the firmware version below the firware button? If you click on the All=1.5mS button do all of the servos go their centered position? Do you have a project setup and it has the proper servo numbers selected.
If none of the stuff in SEQ works have you tried simple stuff with the LYNX SSC-32 terminal program? Can you get it to move a specific servo?
Are you sure none of your servo wires did not get pinched and possibly short out? Sometimes when all else fails I will unplug all of my servos and see if it will talk. If not… But if it can then I keep adding one or more servos and see if it still works, if you add one and it stops then probably something wrong with that servo, or possibly you exceeded your battery and the processor resets, but then you will typically notice that when all of the servos go limp…
Good Luck
Kurt
Hi again,
If you startup Visual sequencer with the RS-232 cable connected from your pc to the SSC-32 card does it show up as connected?
No.
Does it show you the firmware version below the firware button?
No.
If you click on the All=1.5mS button do all of the servos go their centered position?
That button is not active.
Please help!!!
Thanks in advance,

The problem is the communication. Are you using a serial-to-USB cable? If so, there are only a handful of cables that work.
If the SSC-32 receives any data, the green LED will go out. It’s always on, therefore it never received a command from the pc. I would check the cable first, make sure it is securely plugged in on both ends and is of the right type. If you got a known good spare, try that one as well.
This problem is common and it’s usually something cable related or comm port settings.
