5.4 Write 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.
