I’m currently working on a Lynxmotion AL5D arm, that uses the SSC-32 Ver2.01 controller. When assembling the base (lynxmotion.com/images/html/build40d.htm) I’m unable to successfully run the LynxTerm 1.11 test (step 20). When starting the lynxterm, the led is continuously on and the command line doesn’t respond to “ver”. The robot came with a male-female serial cable. I tried an identical serial cable and a usb-to-serial cable with the same results. When the cables accidentally touched the other cable port of the computer the base rotor sputtered.
To the best of my knowledge the connections are fine and properly done. Could the problem be somewhere in the controller, like a damaged microchip or a damaged male port?
Hi and welcome,
For a lot of this, I am referring to the SSC-32 manual: lynxmotion.com/images/html/b … m#ssc32lay
Sorry there is not enough information to give you a good answer, but hopefully a few hints may get you working.
What power are your applying? I am guessing a wall wart (AC connection that probably came with kit) and 9v battery?
Did you make sure the jumpers on the SSC-32 are correct? That is the VL=VS jumper was removed (#5 in diagram).
When you turn the power switches on, does the LED on the SSC-32 light up?
When you first plugged in the USB to serial adapter into your computer, did it show something like installing driver… Did it create a new comm port that you chose in Lynxterm?
When you do a connect in Lynxterm, does it show a successful connect? or first start up the program the next time, does it show it being connected?
When you try something with Lynxterm, does the LED on the SSC-32 blink at all? If not sure right serial port selected? If blinks but no response, have you checked to make sure the
baud jumpers on the SSC-32 (#9 in diagram) match the baud rate that Lynxterm is configured for?
Also TTL/RS232 jumpers still in place (#14) and your RS232 cable is plugged in?
Make sure all servo wires are plugged in correctly, with black wires toward outside of the board. If still no response, may try unplugging all servo wires and see if that helps.
Also check to make sure no shorts on power wires coming in and that they have a good connection. When in doubt I like to use a multi-meter to measure voltages.
we used the correct bauld rate. Today when we were trying to solve the problem we used a 9v battery which resulted in the controller coming online - it now works. It was an embarassingly simple problem, but in my defence the AL5D guide says to use wall power . When I earlier spoke of a led, I meant the one that’s shown in LynxTerm next to the connect button. Only after I consulted the manual you linked I realised that the speck next to serial port is a led.
After all we now know that the problem is in the wall power amp or related wiring, we need to check them again. Thanks for your help.
