Model 2400S Transmitters with Analog Outputs
Connecting with ProLink II or Pocket ProLink Software
3. Start ProLink II or Pocket ProLink software. From the Connection menu, click on
Connect to
Device . In the screen that appears, specify:
•
Protocol
: as appropriate for your connection type
• COM Port : as appropriate for your PC
•
Address
: if required by your connection type
No other parameters are required.
4. Click
Connect
. The software will attempt to make the connection.
Note: While you are connected to the infrared port, both optical switch indicators will flash red, and
both the Scroll and Select optical switches are disabled.
5. If an error message appears:
a. For connections to the service port clips, swap the leads between the two service port
terminals and try again.
b. Ensure that you are using the correct COM port.
c. Check all the wiring between the PC and the transmitter.
3.4.2 Connecting to the HART clips or to a HART multidrop network
To connect to the HART clips or to a HART multidrop network:
1. Attach the HART interface to the serial or USB port of your PC.
2. To connect to a HART multidrop network, connect the HART interface leads to any point on
the network (see Figure 3-2).
WARNING
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 HART
clips, the HART 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.
CAUTION
Connecting a HART device to the transmitter’s mA output terminals or HART
clips could cause transmitter output error.
If the mA output is being used for continuous control, connecting a HART interface
to the output loop could cause the transmitter’s 4–20 mA output to change, which
would affect final control devices.
Set control devices for manual operation before connecting a HART interface to the
transmitter’s mA output loop.
