When operating in uplink/downlink mode the transmission and reception will take about 40 to 50 seconds. In this period the
device will first send a data telegram three times as shown in
consumption for about 20s and will then enter the receive mode for about 20s with 19mA current consumption. Finally a
confirm telegram is sent for about 2s. This uplink/downlink mode is only possible for max. 4 transmissions/day and has to be
added to the Mean Current consumptions in
During the uplink/downlink operation the MCU can be placed in power-down mode and can wake-up by the event of the
ATA8520D.
