TTL serial into the cRIO RS-232 Port?
We'd like to connect a sensor to the RS-232 port of the cRIO. The sensor puts out 9600 baud, 8 bits, no parity, 1 stop bit. No flow control. Alas it's TTL level serial so it swings between 0 and 4.5 v rather than RS-232's spec of +-12v.
Has anyone tried this on a cRIO? I know many RS-232 devices are fine with TTL levels like this but some really want that +-12v. In what camp does the cRIO fall?
If the cRIO is a stickler, does anyone know of a RS-232 level shifter board with it's own onboard power supply that will take in a TTL level serial signal and +5 and/or +12 and convert it into official RS232?
