Full Message Display
The full message display mode provides two types of messages depending on
the type of signal received.
• Position Information
• Status Information
When position information is received, the resulting message output is:
Position<delimiter>Units<delimiter>ID<delimiter>Signal Strength<terminator>
When status information is received, the resulting message output is:
Drift status<delimiter>Battery status<delimiter>ID<delimiter>Signal
Strength<terminator>
The position information is similar to Output Mode 3 with the addition of a signal
strength indication. Signal strength is represented by a value from 0 to 7 where 0
is a very weak signal and 7 is a very strong signal. This can be used for verifying
the quality of signal reception from a particular transmitter location.
The status information is used in conjunction with the drift monitor feature of the
ProScale General Purpose display. If the drift monitor is enabled on the display
and movement is detected outside the drift tolerance range, the display will
indicate a drift condition and a drift signal will be sent on the RF channel. If a low
battery condition is detected, this will also be indicated in the status information.
In the case of the Full Message Display option, the “delete previous
measurement” message is in the format:
DEL<delimiter>ENTRY<delimiter>ID<delimiter>Signal Strength<terminator>,
where DEL is substituted for the position and ENTRY is substituted for the units.
Binary mode output, ProRF emulation
This output mode is intended to be used with applications that were designed for
the ProRF two-way radio interface system. The output from this receiver is a
small subset of the functionality from the ProRF. Since the ProScale RF receiver
is one-way only, no acknowledgment signal can be sent back to the display.
Two different binary message packets are available from the ProScale RF
receiver. One reports a combination position/status message and one reports a
“delete previous record” message. Both of these message packets are
