Connecting with ProLink II or Pocket ProLink Software
Making the connection
To connect to the service port:
1. If you are using the infrared port, position the infrared device for communication with the
infrared port (see Figure 2-2). You do not need to remove the transmitter housing cover.
Note: The infrared port is typically used with Pocket ProLink. To use the infrared port with ProLink II,
a special device is required; the infrared port built into many laptop PCs is not supported. For more
information on using the infrared port with ProLink II, contact Micro Motion customer service.
2. If you are not using the infrared port:
a. Attach the signal converter to the serial or USB port of your PC, using a 25-pin to 9-pin
adapter if required.
b. Remove the transmitter housing cover from the transmitter (see Section 2.3), then connect
the signal converter leads to the service port clips. See Figure 3-1.
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, for
example, for configuration or troubleshooting purposes.
When the transmitter is in an explosive atmosphere, use a different method to
connect to your transmitter.
