CLIP Generator for Serial TTL on SB-RIO

1. I'm unable to read and write to VN-100 sensor. The sensor is connected to SB-RIO 9627 using 3.3volts TX RX lines (PIN 8 and 9 on the sensor). Using CLIP generator in LabVIEW I have setup two pins dedicated for TX and RX. But I get timeout error when trying to write to it. There is nothing wrong with the logic since it works when the sensor is connected to the serial port of the computer. Any ideas? How shall I proceed debugging this?

 

2. Maybe I should connect PIN 2 and 3 from the sensor to the RMC board?

 

3. Also, on the clip generator page it says "This page configues the serial p.... (RS-232)". But RS232 can be more than 3.3volts and the FPGA pins on the RMC Board are rated for 3.3 volts. Can you clarify this?
