Section 6: Configuring the Sampling and Transmission Rates
The Dual Analog Input Transmitter is very versatile with many program-
mable features and can be used in numerous different applications. Be-
cause no two applications are the same, some configuration is required for
each unit. This section will walk you through the initial configuration of
these sample and transmit settings. The subsections are as follows:
6.1: Selecting the Normal Transmission Rate
6.2: Selecting the Normal Sampling Rate
6.3: Selecting the Abnormal Transmission Rate
6.4: Selecting the Abnormal Sampling Rate
6.5: Setting the Smart Rate Threshold
6.6: Selecting the Normal Upper and Lower Values
6.7: Selecting Rates, Thresholds, and Deadbands via the Software
6.1: Selecting the Normal
Transmission Rate*
The Normal Transmission Rate is the interval in which the Transmitter
transmits data to the Base Radio. The Transmitter is in a “sleep” mode to
save power during the operations sequence. This mode turns off most of
the electronics on the unit, with the exception of the LCD, in order to pre-
serve battery life. The Transmitter will then ‘wake up’ every Normal Sam-
pling Period and take the necessary process value readings. The Transmit-
ter will then transmit these readings to the Base Radio on an interval deter-
mined by the Normal Transmission Rate.
Notice that the fastest update rate of the Normal Transmission Rate is de-
pendent on the baud rate setting you selected earlier (see Section 5.2). The
transmission rates cannot update data faster than their communication
speed allows. Thus, if you selected the 19.2K Baud Rate setting, your fast-
est transmission rate will be 5 seconds. The Transmitter automatically
determines these settings and adjusts the menu options accordingly. A
complete table of these parameters is shown in Section 6.2.
In order to properly set the Normal Transmission Rate, you must first de-
termine how often you need updates from the Transmitter. You have a
selectable range of 1-5, 10, 15, 20, 40 seconds and 1 minute. The factory
default is 10 seconds.
If all of the data does not get through, the data is resent the following sec-
ond. This prevents data from being lost. However, if the Transmission
Rate is set to the maximum (1 second; 76.8K baud), then the data cannot
be resent the following second because the next set of data must be sent in
order to meet the Transmission Rate.
