1.4 Jumper Settings
There are three sets of jumper settings located on the back of the module.

MODE 1 - Development Mode Jumper: This is the top jumper, used for
firmware updates only. The two pins should NOT be jumpered during
normal operation.

MODE 2
– Default IP Jumper:
This is the middle jumper. The default IP
address of the ProLinx gateway is 192.168.0.250. Set this jumper to put
the gateway's IP address back to the default.

MODE 3 - Reserved: This is the bottom jumper, reserved for
internal ProSoft Technology use only. The firmware will not run when
these pins are shorted.
1.5 SD Card
PLX3x products can be ordered with an optional SD card (Part Number SDI-1G).
In the event of a disaster, the SD card can be moved from one module to the
next and resume operation. Below is a list of how the module will act - with and
without an SD card.
Without an SD Card

Configuration data is downloaded to the internal memory of the module.

If a blank SD Card is inserted in to the module after the module has been
configured, the configuration data will not be transferred to the SD card.
The configuration data would need to be downloaded to the module while
the SD card is in place.
With an SD Card

Configuration data is downloaded to the SD Card

The configuration data is not transferred from the SD card to the internal
memory of the module. If the SD card is removed and power is cycled to
the module, the module will load the configuration data
from the module’s
memory. If there is no configuration data in the module’s memory, it will
be restored to factory default.
