Installation and Use Manual7
Installation and Setup
During installation on a Windows NT, Windows 2000, or Windows XP system, if the installer is not in
the Administrator group, the installation wizard may display a message warning that the installation
may not be successful. If this occurs, the installation wizard will run to completion but the Windows
registry may not be updated correctly. If you are subsequently unable to connect to a transmitter,
reinstall the software using the required user account.
2.2.2Install the ProLink II software
To install ProLink II software:
1. Insert the ProLink II CD-ROM into the PC’s CD-ROM drive.
2. If the setup program does not start automatically, locate and run the SETUP.EXE file. The file
is located in the root directory on the CD-ROM (e.g., D:\setup.exe, where “D” is your
CD-ROM drive letter).
3. Follow the on-screen instructions to complete the installation. If you have a previous version
of ProLink II installed on your PC, you may be prompted to remove it before installing the
new version.
Note: The ProLink II site key is associated with a disk drive and specific folder on your PC. If you
decide to move ProLink II after installation, you will have to transfer the license and reinstall
ProLink II. To avoid this step, be sure to install ProLink II into a location that you can use
permanently.
Note: If you have a Model 2700 transmitter with transmitter software earlier than v3.4, and you have
the enhanced density application installed, you cannot access the enhanced density functions with
ProLink II v2.1 or later. To configure and manage the enhanced density application from ProLink II,
you must either upgrade your transmitter software to v3.4 or later, or continue to use ProLink II v1.x
with enhanced density support. You can install both ProLink II v1.x and ProLink II v2.0 or later on
the same PC, and you can use ProLink II v2.0 or later with your pre–v3.4 transmitter for all functions
except enhanced density. You can also use ProLink v1.2 with transmitter software v3.4 and later;
however, not all transmitter functions will be accessible using the older program.
2.2.3Generate the temporary license
The first time ProLink II is run, you will be prompted to generate a temporary license. This license
will allow you to run ProLink II with full functionality for seven days, starting from the current date
and time. Follow the on-screen instructions to generate the temporary license.
Note: If you are running Windows 98 or Windows ME, you must temporarily disable any anti-virus
software running on your PC before you can generate the temporary license. You can re-enable the
anti-virus software immediately after the temporary license has been successfully generated.
Continue with Section 2.2.4 to use ProLink II for seven days. During this time period, follow the
instructions in Section 2.2.7 to obtain and configure a site key.
Note: If you attempt to use ProLink II after the temporary license has expired, ProLink II will no
longer allow you to connect to a transmitter.

Installation and Setup
2.2.4Determine your connection type
Different transmitters and networks support different connection types.
•Table 2-2 lists the supported protocols and wiring methods for IFT97xx and RFT97xx
transmitters.
•Table 2-3 lists the supported protocols and wiring methods for Model 1500/2500,
Model 1700/2700, and Series 3000 transmitters.
•Table 2-4 lists the supported protocols and wiring methods for the Model 2400S transmitter.
•Table 2-5 lists the supported protocols and wiring methods for all MVD Direct Connect
systems.
In these tables, and throughout the chapter:
•Temporary – refers to a connection that is not permanent and is typically used only for
configuration and troubleshooting. Because the transmitter housing must be open for the
duration of the connection, these connections should be removed and the housing closed as
soon as possible. The operator should be aware of the safety hazards that result from opening
the transmitter housing.
•Hard-wired – refers to a connection that is made to the permanent wiring, usually a transmitter
output wire or the network that the transmitter is already using. Because hard-wired
connections do not require the transmitter housing to be open, they can be left in place as
desired.
ProLink II SetupTransmitter StartupUsing ProLink IIBefore You Begin
•AN – refers to transmitters with the analog outputs option board
•IS – refers to transmitters with the intrinsically safe outputs option board
•CIO – refers to transmitters with the configurable input/outputs option board
•FF – refers to transmitters with the F
OUNDATION fieldbus input/output option board
•PA – refers to transmitters with the PROFIBUS-PA input/output option board
•DP – refers to transmitters with the PROFIBUS-DP input/output option board
•DN – refers to transmitters with the DeviceNet input/output option board
•MVD Direct Connect – refers to meter installations that include the core processor but do not
include a transmitter. ProLink II is connected directly to the RS-485 terminals on the core
processor or the MVD Direct Connect I.S. barrier.
Once you have determined your connection type, use the Wiring Method # value in the table to direct
you to the correct wiring procedure in Section 2.2.5.

can expose the operator to electric shock.
To avoid the risk of electric shock, do not touch the power supply wires or terminals
while using the service port.
Installation and Use Manual11
Installation and Setup
On Model 3350/3700 transmitters, opening the wiring compartment in
explosive atmospheres can cause an explosion.
Do not remove the compartment covers in an explosive atmosphere within three
minutes after power is disconnected.
On Model 2400S transmitters, removing the transmitter housing cover in a
hazardous area can cause an explosion.
Because the housing cover must be removed to connect to this transmitter using
the service port clips or HART clips, these connections 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.

WARNING
Removing the core processor lid can expose the operator to electric shock.
To avoid the risk of electric shock, do not touch the power supply wires or terminals
while removing or replacing the core processor lid, or while using the RS-485
terminals.
CAUTION
Connecting a HART device to the transmitter’s primary mA output could
cause transmitter output error.
If the primary mA output is being used for flow control, connecting the VIATOR
HART Interface to the output loop, via either the mA terminals or the HART clips,
could cause the transmitter’s 4–20 mA output to change, which would affect flow
control devices.

3. Ensure that your wiring meets the following requirements:
•For basic analog output operation, the primary mA output requires an external power
supply with a minimum of 250 Ω and 17.5 volts. See Figure 2-5.
•For communication, the VIATOR HART Interface must be connected across a resistance
of 250–600 Ω. See Figure 2-4.
To meet the resistance requirements, you may use any combination of resistors R1, R2,
and R3:
-If no other device is connected to the primary mA output, add resistor R1 in series with the
primary mA output.
-If the primary mA output is connected to a remote device such as a DCS or a PLC with an
internal resistor (R2), ensure its value is between 250 and 600 Ω. If it is lower than 250 Ω,
add resistor R1 to the connection so that the overall resistance (R1 + R2) is between 250
and 600 Ω.
-If your DCS or PLC does not have an internal resistor, add resistor R3 and make sure its
value is between 250 and 600 Ω

3. For long-distance communication, or if noise from an external source interferes with the
signal, install 120-Ω, 1/2-watt resistors (R1) across terminals of both end devices.
Note: The Modbus protocol allows only one Modbus master to be active on the network at any given
time. If you are connecting through a network, ensure that no other Modbus master devices are
currently active.

Method 7: Modbus/RS-485 temporary connection to service port
Note: This method is supported by all Series 1000, Series 2000 and Series 3000 transmitters.
Using a Black Box signal converter, the PC can be connected directly to a transmitter’s service port.
Figure 2-8 shows the wiring for this connection type.
1. At the PC, attach the Black Box signal converter to the PC’s serial or USB port, using a 25-pin
to 9-pin adapter if necessary.
2. At the transmitter, connect the signal converter leads to the service port terminals. See
Table 2-11. For assistance in identifying the terminals, see Appendix A.
•If you are connecting to a Model 1700/2700 or to a Model 2400S transmitter, the service
•If you are connecting to a Model 1500/2500 transmitter or a Series 3000 transmitter, the
port terminals are available at any time.
RS-485 terminals on these transmitters are accessible as a service port for a 10-second
interval after power-up:
-If a service port connection is made during this interval, the port will remain in service
port mode indefinitely until power is cycled.
-If no service port connection is made during this interval, the terminals switch to
Modbus/RS-485 mode, and must be accessed using the RS-485 communication
settings configured in the transmitter (see Method 6).
Service port connections to these transmitters are discussed in detail in Section 2.2.6.
Note: The Modbus protocol allows only one Modbus master to be active on the network at any given
time. If you are connecting through a network, ensure that no other Modbus master devices are
currently active.
Note: All service ports are accessed using the default address of 111. If you are connecting over a
multidrop network with multiple service ports, it is not possible to specify which device to connect to.

Method 8: HART/Bell 202 temporary connection to HART clips
Note: This method is supported by Model 2400S transmitters that support HART communication.
Using a VIATOR HART Interface, the PC can be connected directly to the HART clips on the face of
the transmitter. Figure 2-9 shows the wiring for connection to the HART clips.
1. At the PC, attach the VIATOR HART Interface to the PC’s serial or USB port, using a 25-pin
to 9-pin adapter if necessary.
2. At the transmitter, remove the housing cover.
3. Connect the HART interface leads to the HART clips.

4. If necessary, add a resistance across the HART clips. The VIATOR HART interface must be
connected across a resistance of 250–600 Ω. Note that the HART clips use the same circuit as
the mA output, so the required resistance may already be installed if the mA output loop is
connected to a remote device or a HART network (see Figure 2-1).

Method 9: Modbus/RS-485 temporary connection to MVD Direct Connect
Using a Black Box signal converter, the PC can be connected directly to the RS-485 terminals on the
core processor or the MVD Direct Connect I.S. barrier.
1. At the PC, attach the Black Box signal converter to the PC’s serial or USB port, using a 25-pin
to 9-pin adapter if necessary.
2. If connecting to the core processor, remove the lid.
3. Connect the signal converter leads to the RS-485 terminals. See Table 2-12, and:
•For connecting to the standard core processor, see Figure 2-10.
•For connecting to the enhanced core processor, see Figure 2-11.
•For connecting to the I.S. barrier, see Figure 2-12.
Note: The Modbus protocol allows only one Modbus master to be active on the network at any given
time. If you are connecting through a network, ensure that no other Modbus master devices are
currently active.
Note: Before using ProLink II to communicate with the core processor, disconnect any wiring to a
remote PLC. Be careful not to disconnect the power supply wiring. After using ProLink II to
communicate with the core processor, reconnect the wiring to the remote PLC.
