5.4Write Protect Option

Write Protect Option

The SMV 3000 transmitters are available with a “write protect option”. It

 

consists of a jumper located on the transmitter’s Main Printed Circuit

 

Board (PCB) under the temperature measurement (Daughter) PCB that

 

you can position to allow read and write access or read only access to the

 

transmitter’s configuration database. When the jumper is in the read only

 

position, you can only read/view the transmitter’s configuration and

 

calibration data. Note that the factory default jumper position is for read

 

and write access. There is no need to check jumper position unless you

 

want to change it.

 

Figure 19 shows the location of the write protect jumper on the electronics

 

module for SMV 3000 transmitters.
