I have a Vantage Pro 2 with a recent datalogger, and with the included 8 foot RJ11 extension cable and a PL2303 USB/serial adaptor (to a 2008 vintage Mac notebook running NetBSD), weewx is running fine.
I am about to run cables from the console to a more reasonable place for the computer. I notice that Davis specifies 48' max (the 8' plus a non-supplied 40'). I am inclined to use some CAT3 or CAT5 cable and use 2 pairs, one with ground/TX and one with ground/TX, and wire up a short connecting cable at each end to a DB9. My planned run might be a little longer than the 48' spec. So I wonder: Has anybody used a too-long cable, and did it work ok? What type, length and ok or not? The datalogger is labeled serial, but I notice it doesn't say RS232. Is it real RS232 levels (-12V/+12V, ish), or TTL (0/5V)?
