Logging serial data from CO2 meter

Anyone have some insight on setting this up I'm having some problems.

I have a supco iaq50 and a sentinel cppm-4. Output on the the cppm-4 is db-9, and on the supco I think its 3.5mm.

I have a usb to serial converter. I set it up, and using linux and moserial, I couldn't get any data. I was able to receive data from an older serial device using this setup.

The manual for supco just says baud 9600 8 bits of data and no parity. The cppm4 says nothing.

Any ideas?
