Second Receiver Output Voltage
First Receiver Output Voltage
Non-inverting Complementary Receiver Output, always active
for wake-up
Output of the valid signal detector. Indicates if a valid RS-232
level is present on receiver inputs logic "1"
Drive low to shut down transmitters and on-board power
supply. This over-rides all automatic circuitry and FORCEON
Drive high to override automatic circuitry keeping transmitters
on (FORCEOFF must be high)
