Indicator Mode
The device may be configured to blink the LED activity indicator every 10 seconds (the factory
default setting) or only when a scheduled reading is taken. The green LED indicator will blink to
indicate that the device is configured properly to allow a wireless transmission to occur. If the
wireless transmitter is disabled by any of the available configuration options (by setting the
transmitter output mode to disable the wireless output, or by selecting either of the related transmitter
control options), the indicator will not blink. When a wireless transmission is about to be sent, both
the green and the red LED indicators will blink.
The primary reason to turn off the 10-second indicator is to conserve battery capacity. See “Battery
Life” later in this manual. The 10-second mode is forced "on" if the custom transmit interval
discussed above is enabled.
Wireless: Registering the Device on a System
Before the Dwyer software will receive data from an RF-series transmitter, the device must be
properly registered on the system. When the device is identified or configured, the PC software will
store an image of the device for future reference. This image is stored on the PC’s hard disk so it is
retained even when the software or PC is shut down. The software then refers to the device image
when receiving a transmission to “fill in” the information that is not transmitted in the data packet.
This information includes the device ID, calibration date, and measurement variables such as a
thermocouple type or engineering units. The data packet contains a checksum of critical settings to
