8 servo controller

I’m having some problems with my servo controller.When i turn it on Yellow LED is
on. As soon as a have my serial cable connected Yellow LED goes off.
When I’m trying to send data all LEDs (Green,Red,Yellow) are flashing.
Tried to use different mods,different software - problem follows.

Can anyone help me to figure this out.
Thanks. :cry:


If connecting the serial cable makes the yellow LED go out, the servo controller is most likely getting reset by the handshaking lines. Taking off the reset jumper should take care of that.
