For the past two weeks we have been trying to connect to the Hexapod CHR-3. Eventually after no avail, we switched to testing the Biped BRAT. We were able to communicate with the ATOMPRO, and then the ATOMPRO on the CHR-3. But we still can’t connect to the SSC-32 through PowerPod or the Calibration program. When we go to connect we get absolutely no signal through the comport (tested COM36 and COM2). We know that it isn’t the cable because we have been able to connect to the basic ATOMPRO software. We tried two different SSC-32 boards and could not connect to that either. We are at a complete loss with this board.
If anyone could post the latest version of how the SSC-32 should be electrically wired, in case we are reading from the wrong guide.
Also if anyone else knows about a bug like this from the program? Thanks in advance.
Hello,
You can find the SSC-32 manual at this location:
Items 2-6 explain the different ways to connect the power to the SSC-32, item 7 explain how to connect the servos, and you can find images showing the servo connections a bit further down the page.
For your connection problem, it sounds like it might be a baud rate configuration problem. Item 9 shows how to configure the SSC-32 to use either 2400, 9600, 38,400 or 115,200 kbps and you need to configure PowerPod to use the same speed (using the Setup button). At the same time, you can also verify that the rest of the settings are: 8 data bits, 1 stop bit, no parity and no flow control.
If this doesn’t work, could you say if you are using a regular serial cable to connect to the COM port of your computer, or using a USB-to-serial converter?
Hope this helps,
Jeffrey
For simple testing you may want to use the lynxterm application.
some things to try. When the ssc-32 is reset, a green LED lights on the board. When serial activity is detected the LED goes out. You can send a VER command and the ssc-32 will respond with the version number. I think a jumper can be put across the TTL tx/rx pins and then what is sent to the ssc-32 will be echoed back to the sender.
I’ll test the new things on Monday when I am able to get back to the shop.
We are using a USB - to - Serial adapter, but the adapter does work, we tested it with the basic micro. The LED never goes out on the SSC-32 when we connect it. The cable has three LEDs on it, Link, RX, TX. RX and TX light up when we connect via basic micro studio, and link is on if it is connected to the computer. When we run PowerPod and Hexapod Calibration the cable never receives signal to RX and TX
