Hi community,
I recently purchased a SSC-32U (firmware v2.50) from Robotshop, but I cant seem to get my ssc-32u to receive commands from my Arduino Uno.
Arduino pin 1 (TX) connected to SSC-32U RX pin and GND to GND. SSC-32U is set to baud 9600 A led green.
Powering up the SSC-32U at VS1 with 5V power supply, VL with 9V powersupply. no VL VS jumper
I can control and communicate using USB cable and servo sequencer utility, but cannot control from arduino, that is with USB cable unplugged and using RX/TX/GND cables.
doesnt look like the SSC-32U receives any bytes because both A&B leds remain on after power up.
I’m worried that there might be something wrong with the board.
Below is the arduino sketch I’m using.
Any help would be appreciated.
THANKS in advance

[code]////////////////////
void setup() //initializing serial communication baud rate
{
Serial.begin(9600); //sets the baud rate at 9600 to match the one set on the SSC-32 board
}
void loop()
{
Serial.println("#1P500T1000"); //turns the servo to the initial position in 1 second
delay(1000); //delay for 1 second
Serial.println("#1P2500T1000"); //turns the servo to the final position in 1 second
Can you provide a few clear images of your setup?
Note that you do not need to apply power to VL on the SSC-32U - please remove this immediately as you may still have the VL = VS jumper in place.
5v from Arduino to VS1
Arduino Pin1(tx) to SSC-32U pin RX
Arduino GND to SSC-32U pin G
See attached picture of my setup
Baud lights A&B stay on after power cycle, pushing the baud button one causes light A to blink then all off (indicating 9600) arduino code is set for 9600 also
Any suggestions of why this setup does not work.
Thanks
After some more frustrating testing I decided to whip out my multi-meter and discovered there was no continuity between RX and ground but there was between TX and ground. I found a bad solder joint on the RX pin and the 102 resistor next to it. See image below bad area circled in red. By just prodding that area with my multimeter,
I was able to get continuity and my Arduino is now communicating and all is good. I hope it will hold, I dont have that kind of soldering skills. Now should I have it exchanged?? I guess I will just hang on to it for now
I decided to return the board after I had a hard time maintaining comms with that loose solder point.
I received a RMA the next day and my replacement board was also shipped.
