IE: DAMPER END <br />SWITCH. <br />ANALOG INPUT - A MODULATING SIGNAL THAT COMES FROM THE FIELD DEVICE TO THE BAS SYSTEM. IE: THERMOSTAT. <br />ANALOG OUTPUT - A MODULATING SIGNAL SENT OUT FROM THE BAS TO THE FIELD DEVICE. IE: FLOW CONTROL VALVE. <br />DIGITAL INPUT -A BINARY SIGNAL THAT COMES FROM THE FIELD DEVICE TO THE BAS SYSTEM. IE: FLOW SWITCH: <br />DIGITAL OUTPUT - A BINARY SIGNAL SENT OUT FROM THE BAS TO THE FIELD DEVICE. IE: FAN STARTISTOP <br />COMMUNICATION WIRING- WIRING BETWEEN CONTROLLERS IN A RAS SYSTEM. ALLOWS NUMEROUS POINTS OF INFORMATION <br />TO COMMUNICATE THROUGH THE NETWORK CABLE. BAS NETWORK SPEED AND TRAFFIC CAN EFFECT CONTROLLABILITY. <br />BACNET MS/TP IS THE MOST COMMON COMMUNICATION WIRING, REQUIRING 22 GAUGE TWISTED PAIR WIRING BETWEEN THE <br />CONTROLLERS.
