An input/output device (100) comprises a transmitter (108) configured to generate a radio frequency signal transmission, a receiver (110) configured to receive a radio frequency signal transmission, and processorbased control coordinating transmissions of radio frequency signal transmissions in response to received signal transmissions in a multi-signal 10 path transmission network. The processor-based control is configured to: receive a route request including a destination for a proposed communication over the network; receive a route request including a destination for a proposed communication over the network; determine whether the input/output device (100) is the destination, and, if so, generate and transmit a 15 route reply message without delay; and if the input/output device (100) is not the destination, determine whether a signal path to the destination from the input/output device (100) to the destination is available, and if a signal path to the destination is available, generate and transmit a route reply message after at least a first predetermined amount of delay. 20 6229906_11/5 118 Power Supply 100 Radio 113 Se so 10 - PM m ory 0 114-, Sensor 2 - M 106 116 Control Device Transmitter Receiver 110 108 SCADA System / 1 FIG. 1 156 156 100 154 Control F Control 154 A Comm 1 D G Comm 2 Com~m 1 154 Comm 2] Comm 3 C Sensor 1Sensor 2 Sensor3 B Control L Control LeK 156 -,Comm 3 Comm 4 -- 156 M ~156 N Control OComm 5 p Q Gateway -- 124 Control Center 126 FIG. 2
