12 Transmitter Configuration and Use: Series 1000 and 2000 Transmitters
Connecting with ProLink II Software continued
To access the configuration upload/download function:
1. Connect ProLink II to your transmitter as described in this chapter.
2. Open the
File menu.
• To save a configuration file to a PC, use the
Load from Xmtr to File option.
• To restore or load a configuration file to a transmitter, use the
Send to Xmtr from File
option.
3.4 Connecting from a PC to a Model 1700 or Model 2700 transmitter
Depending on your transmitter, there are several options for connecting ProLink II to your transmitter.
See Table 3-1.
Note: Service port connections use standard settings, do not require transmitter configuration, and
are always available. Therefore, they are easy and convenient. However, service port connections
require opening the power supply compartment. Accordingly, service port connections should be used
only for temporary connections, and may require extra safety precautions.
Note: Due to the design of HART protocol, connections made using HART protocol are slower than
connections that use Modbus protocol. If you use HART protocol, you cannot open more than one
ProLink II window at a time.
3.4.1 Connecting to the service port
To connect to the service port, which is located in the non-intrinsically safe power
supply compartment (see Figure 3-1):
1. Attach the signal converter to the serial port of your PC, using a 25-pin to
9-pin adapter if required.
2. Open the cover to the wiring compartment.
