Hello! Please help a novice to use Tumpa. Yet could only use TTL, and that does not work correctly, the feeling there is not enough supply 5 volts when measured 4.85volt, and the board comes from 5,1volt usb. I can not connect to RS232, jumpers are set correctly, but when checking the terminal signal is not present, and try to connect any device to any RS232, the computer does not detect it. Thanks for any help.

Please send screenshot from PC device manager, that shows all USB devices.
AFAIK 4.85 Vdc is enough to run TUMPA. did you try swapping TX/RX.?

Eugene

Thank you for answering! TUMPA runs. TTL works. Does not work RS232, jtag and spi. Screenshot device manager.
Thanks

Yes, of course I read the instructions. Jumpers are set rs232- out . Devices, connected to the com port is not determined by the PC. I must see them when you connect? com mouse for diagnosis is not determined. Thank you, I'm there already applied, forward support. Do you think the hardware is defective?

Please see;

You should try rs232 loopback test.;
http://www.ni.com/white-paper/3450/en/
if loopback test succeeds it means hardware is OKay, if test fails then hardware may be faulty (contact TIAO customer care in that case)

Eugene

Thanks. looptest fails. R/X flashes, but the text does not appear in giperterminal. Drivers are configured as follows: for A (245 Hardware FIFO driver d2XX for B (Hardware RS232 uart, driver - Virtual COM Port). I think that this is the correct configuration. I do not know what else to try, waiting for help from support. Thank you

Eugene

Somebody try to make looptest RS232. It works at all or not? Tell me, has turned or not anyone else. Thanks

Check your connections and also Try with different terminal software.
Normally loopback test should work. If RS232 is still not working, Please contact TIAO customer care;
