PCI 1 Port RS422/485 Fail Safe Open Circuit Detection Open circuit is when there are no drivers on the circuit. This occurs by design in party line multi driver/receiver systems and unintentionally when the twisted pair line is accidentally cut or disconnected or the transmitting device fails. -
Page 56: Rs422 Serial Port Cables
PCI 1 Port RS422/485 This RS422 arrangement allows data to be transmitted and received simultaneously since each signal has its own data cable pair. In addition, the receiver can set RTS true so telling the transmitter on its CTS input that the receiver is ready to accept data. -
