HART/Bell 202 connections
-
HART/Bell 202 connections are available on all transmitters that have an mA output, 
except the Model 1500 with the Filling and Dosing application. The transmitter 
Model 1500 with the Filling and Dosing application does not support HART 
communication.
-
HART/Bell 202 connections use standard connection parameters, so you don’t have to 
know the transmitter’s configuration.
-
Because the HART/Bell 202 connection is made over the primary mA output terminals, 
the communication signal can interfere with certain procedures such as loop testing, and 
may cause the output to change. Depending on how the primary mA output is being used, 
this may have significant consequences for process control.
-
Depending on the transmitter and wiring method, HART/Bell 202 connections may be 
appropriate for both temporary and permanent connections.
RS-485 connections
-
RS-485 connections are not available on all transmitters.
-
To use an RS-485 connection, you must know the transmitter’s configuration.
-
RS-485 connections are appropriate for both temporary and permanent connections.
Making the connection
1. Ensure that your PC is connected to a transmitter, using one of the methods described in 
2. If the 
Connect
 dialog box is not displayed:
a.
Open the 
Connection
 menu.
b.
Click on the 
Connect
 option.
3. Select the protocol to use. Depending on the 
Protocol
 option that you choose, different 
communications options will be available for configuration.
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.
Note: Windows NT does not support USB connections.
Note: If you are using a service port connection to a Model 1500/2500 transmitter or a Series 3000 
transmitter, see Section 2.2.6 for instru
ctions on making this connection.
4. Specify 
Baud Rate
Parity
Stop Bits
COM Port
, and 
Address/Tag
 as appropriate for your 
connection and transmitter. See Section 2.2.6 for more information on these parameters.
Note: If you are using HART protocol and a HART tag (software tag) has been configured for your 
transmitter, you can specify the HART tag instead of the HART address.
5. If you are using the Viator USB HART Interface, enable 
Converter Toggles RTS
.
6. Click the 
Connect
 button.
Note: ProLink II can connect to only one transmitter at a time. To connect to another transmitter, you 
must first disconnect from the current connection.
