SL869 V2 EVK UART 2

  1. Trying to connect the second TTL port on J4 (RX2 and TX2/BOOT) to another IC, but I can’t get any output from it.  I can connect to the through the USB (J1) just fine, but can’t use USB on the IC I’m connecting to.  Is there something I have to do to get the data to come out of both the USB and the TTL port on J4 or just J4?

      Hi Curtis,

      the uart 2 port that should be accessible through J4 is not internally connected in the module so you cannot get the data to come out from from that one.

      If you have other questions please send a mail to TS-EMEA <ts-emea@telit.com>.
