Hello,
I am having trouble getting RIOS to move the arm accurately and do programmed movements. Setting the arm at 1.5mS and then configuring and enabling all the servos goes smoothly, but when I go into the Arm/Moves screens, the arm does not match up correctly with the onscreen diagram and it does not move accurately.
Also, when I try to program sequences of motion, only the gripper and wrist servos respond.
Does anyone else have this problem?
The first thing we need to work on is the powering. Whenever weird things happen it’s the most likely cause. Did you install the 9vdc battery clip onto the VL terminal as suggested in step 15 and 16 of the base assembly manual?

Hope this helps, Jim
No, I assumed that plugging it into wall-power negated the need for a 9 volt. Would having both wall power and the 9 volt hooked up fix the problem?
I can’t know for sure, but I am saying this is the first step if the SSC-32 controller is acting up. It’s very likely the SSC-32 is resetting.
While we’re at it. What PC (make and model), and OS are you using? Does it have a DB9 serial port, or only USB. If you are using a USB to serial cable, what brand is it? (make and model)
I am using a Dell D800 Laptop with serial connection running on Windows XP
Ho, good answer. You should not be having any communications issues then. I’m pretty confident you’re just seeing the SSC-32 reset.
so…9 volt needed then?
Based on all the problems people have been having with the SSC-32 reseting, I think you need a longer start up from a reset with a solid LED on the whole time, something like 3 seconds start.
A REALLY BIG red LED may help too… 
ok, so i got the 9 volt and all the servos are working (i still don’t really understand that one, wouldn’t the wallpower be constant?)
but i am still having trouble matching the arm up to the program. the arm matches up when i go to 1.5ms and configuration of servos, but in moves/playback mode, the arm does not match up with the onscreen diagram and moves. any thoughts?
i am also seeing that when the onscreen diagram shows the arm going up, the arm is actually physically going down. i don’t think the servos were installed backwards, is there some button i need to click in the configuration screen to reverse the signals being sent to the servos?
Bingo!
Step 6 Figure 7 in the manual.

There are reverse boxes that should be enabled. Hope this helps!
I’m not really getting your point. The SSC-32 resetting is simply when the wall pack can’t supply enough current to the servos. When this happens the voltage drops below 5.5vdc on the VL terminal and the 5vdc regulator shuts down. When the SSC-32 resets the servo pulses turn off and the voltage sag goes away. It can cause some really weird things to happen. So the fix is to supply the VL terminal with a separate supply, the 9vdc battery.
But it would be easier for people to notice when their SSC is reseting.
