HARDWARE DIP SWITCH FUNCTIONS

There are four switches on the Microprocessor/Display PCB Assembly that perform unique transmitter functions. The

figure below shows the location and function of these switches.

Figure 34 – Hardware Dip Switch Location and Function

Switch number 1 is the Write Lock. When this switch is in the ON position and the Hardware Write Lock is selected in

the Resource Block FEATURE_SEL, the transmitter prevents any modification of data or parameters that can be

performed both locally and from a class 1 or 2 MASTER device.

Switch number 2 is used to set the transmitter into Simulation mode.

Switch number 3 is used for Cold Startup. When this switch is in the ON position before powering up the transmitter,

most transmitter parameters are set to default values (See Device Blocks for default settings). These default

parameters are found in both the Transducer and Analog Input Function Blocks.

Switch number 4 is not used and has been reserved for future use.

Note.

A Cold Startup will adjust several parameters to a defined default value. Cold Startup may be used to reset the

initial operating condition of the transmitter. When the Cold Start switch is in the ON position on transmitter

power up, critical transmitter parameters will be reset to default values. The SW3 switch must be in the OFF

position to ensure user configured data is not overwritten on transmitter power up.
