Linksys Wrt And SSC32 TTL

Hi!
This is my first post in this forum, although I`ve been hiding in the shadows for a loooong time. 8)

The sole reason for me posting here is of course my desperate need for help!

So, Here we go!

I have a linksys Wrt54G router Running the OpenWrt White Russian Firmware. This is in turn connected to the ssc-32 using a simple 2 wire to the TTL RX. This works great!
I can telnet to the router using netcat and output data to the servo controller, and the servos does move.
But this is also where the problem begins: I cannot make the servo move to a definite position. when I send the commands to the serial port, it seems it does not consider the timing or speed variable. If I send "#0 P1600 S750 " the servo will move. If i repeat the command enough times it will eventually reach the desired position but only by small steps…
When I connect the SSC-32 to one of my computers it works properly with the same command.

PS! Sorry for my bad english…

Cheers Morten

Glad you finally posted. :smiley:

What you are describing is a classic case of the SSC-32 resetting. This means the power applied to it is not strong enough. The easiest way to verify this is to watch the green LED. When you power on the SSC-32 it should be on. However after it receives a valid command the LED will go out, and after that it should blink when it is receiving data. If you send it a command and the servo moves a little, then the LED is on steady, that means the SSC-32 has reset. How to prevent this you ask? Remove the jumper VS1=VL, connect a 9vdc battery clip to the VL input, and power the servos with the VS terminal as normal. Let us know if this helped. :wink:

Thank you very much for your help, it was as you said, low voltage to the controller. Doh! I should have figured, I actually had the same problem when I first recieved the SSC… Well, we`re all learning from mistakes, right?
:blush:

This means it is possible for me to use the WRT as a networked control device, while using the Mini-itx solely for the 4 video streams!

Anyways, thanks for the help!
