UART wiring for Sipy to FOCA converter
I would greatly appreciate your assistance.
I am trying to connect my Sipy to Windows PC via a Foca USB to Serial converter. I just cant seem to get it to work.
A few questions:
- The output pins on the converter are VCC, GND, TX, RX and DTR. To which pin on the Sipy do I connect the DTR output to?
- My current connections are:
- VCC to VCC
- GNV to GNV
- TX to RX
- RX to TX
- DTR to RTS (pin 11)
I am using Putty to connect. I get to the terminal screen but the cursor stays solid green.
- A previous program is running and the unit is flashing blue every 4 seconds
How do I get the Serial comms working.
a) You must set Putty to "No flow control", 8 N 1
b) Try to exchange RX/TX. (RX to Rx, TX to TX). The labeling is sometimes swapped.
c) And yes, you do not need DTR.
I don't know about the DTR pin, I don't think you need it.
Did you install the drivers?
