Connect to Device. In the

screen that appears, specify connection parameters appropriate to your connection:

• Immediately after the transmitter is powered up, terminals 33 and 34 are available in

service port mode for 10 seconds. To connect during this period, set

Protocol to Service

Port, and set

COM port to the appropriate value for your PC. Baud rate, Stop bits, and

Parity are set to standard values and cannot be changed (see Table 3-2).

• If no connection is made during the 10-second period, the terminals are automatically

reset to the configured RS-485 communication parameters. To connect, set the connection

parameters to the values configured in your transmitter (see Table 3-2).

6. Click the Connect button. ProLink will attempt to make the connection.
