In high resolution mode, the temperature = (Modbus register value) ÷ 20. In low resolution mode, the temperature is (Modbus register
value) ÷ 2.
Temperature values are stored as signed values in the Modbus register. A 0 in the register is interpreted as 0°; and 65535 in the register
(0xFFFF) is interpreted as −1 ÷ 20 = −0.05° in high resolution mode and –1 ÷ 2 = –0.5° in low resolution mode.
Storage Mode and Sleep Mode
While in storage mode, the radio does not operate. All SureCross
®
radios powered from an integrated battery ship from the factory in
storage mode to conserve the battery. To wake the device, press and hold button 1 for five seconds. To put any FlexPower
®
or integra-
ted battery SureCross radio into storage mode, press and hold button 1 for five seconds. The radio is in storage mode when the LEDs
stop blinking, but in some models, the LCD remains on for an additional minute after the radio enters storage mode. After a device has
entered storage mode, you must wait one minute before waking it.
During normal operation, the SureCross radio devices enter sleep mode after 15 minutes of operation. The radio continues to function,
but the LCD goes blank. To wake the device, press any button.
