Connecting with ProLink II or Pocket ProLink Software

WARNING

Removing the transmitter housing cover in a hazardous area can cause an explosion.

Because the transmitter housing cover must be removed to connect to the service port clips, the service port clips should be used only for temporary connections, e.g., for configuration or troubleshooting purposes.

When the transmitter is in an explosive atmosphere, use a different method to connect to your transmitter.
