2.5Optional Write Protect Jumper
Write protect option | The ST 3000 transmitters are available with a “write protect option”. It |
| consists of a jumper located on the transmitter’s PWA 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 the jumper position unless you want to change |
| it. Refer to the steps in Table 4 to remove the PWA from the transmitter |
| and Figure 3 to reposition the jumper. |
| Figure 3 shows the location of the write protect jumper on the PWA for |
| Release 300 transmitters. |
