Problem connecting SSC-32 to lynxterminal again

Ok so I am having problem sending commands to the SSC-32 from lynxterminal, as this is the second time this is happening to me, I am guessing I am doing this wrong so I require your help. The first time the SSC was defective, but this time the SSC is brand new. This is a 4DOF Hex with 24 Servos.

0th. I plugged only two servos (channel 0 and channel 1) to the SSC-32 board.
1st. applied the jumpers on TX and RX the right way.
2nd. Set up baud rate for both the SSC-32 and lynterminal to be 15200
3rd. I plugged in a cable from servo board to computer (Using a USB converter).
4th. I removed the VL=VS1 jumper and the VS1=VS2 jumpers and powered VL and VS1 with different batteries; 9.6V 1000 mAh and 6V 2800 mAh respectively. The green light on the SSC-32 turned on.
5th. Opened lynxterminal, The green light on the SSC-32 turned off. I wrote VER but got no output from the terminal. I clicked on timeouts, then clicked ‘VER’ Test, it read 0 bytes. I clicked on REG "Can’t find SSC-32’. :imp: :angry:
6th. I proceeded to check if the cable was wrong or the SSC, so I removed the TX and RX jumpers and connected the SSC-32 along with a Bot Board II. I wrote the code below and programmed the Bot Board II (using the same USB cable) to see if the servos would move accordingly.

SSC con P11
Baud con i115200

Main

serout SSC, Baud,"#0 P1500 S750", 13]
pause 1000
serout SSC, Baud,"#1 P1500 S750", 13]
serout s_out,i9600,"Done with this"]

goto Main

The servos moved as predicted.

  • Why can the Bot board II talk to the SSC-32 but the Lynxterminal can’t?
  • The USB cable is not defective since I programmed the Bot Board II with the same cable.
  • This is frustrating, what am I doing wrong, help? :cry: :cry: :cry: :unamused:

Hi Kike89,

We are sorry to hear you are having problems with the SSC-32.

Your notes show pretty thorough debugging: could you send us a clear picture of your setup when you have the SSC-32 plugged into your computer? It should show SSC-32, the USB-to-serial adapter, and your connected batteries and servos.

We would also like to confirm the options you’ve specified in the “Setup” screen of LynxTerminal:

]Port: the same COM port you used to upload your Bot Board configuration (if you have not disconnected your USB-to-serial adapter since then)/:m]
]Baud rate: 115200/:m]
]Data bits: 8/:m]
]Stop bits: 1/:m]
]Parity: None/:m]
]Flow control: None/:m]

We would also like to confirm that it’s normal for the the green light on the SSC-32 turned off when you do a Connection with LynxTerminal.

Thanks for choosing RobotShop,
Jeffrey

Parity was not set to NONE… thank you!
