26 Micro Motion Series 1000 and Series 2000 Transmitters
Connecting with ProLink II or Pocket ProLink Software
3.5.2 HART/Bell 202 connections
Follow the instructions below to make the connection.
1. Connect the HART interface to your PC’s serial or USB port. Then connect the leads of the
HART interface to terminals 21 and 22 on the transmitter (see Figure 3-9).
Figure 3-9 HART/Bell 202 connections to Model 1500 or 2500
2. Add 250–600 Ω resistance to the connection, as required.
3. Start ProLink II. Choose
Connection > Connect to Device.
4. In the screen that appears, set
Protocol to HART Bell 202. Baud rate, Stop bits, and Parity
are automatically set to the values required by HART protocol. Specify the remaining
connection parameters as shown in Table 3-3.
CAUTION
Connecting a HART device to the transmitter’s primary mA output terminals
could cause transmitter output error.
If the primary mA output is being used for flow control, connecting a HART device
to the output loop could cause the transmitter’s 4–20 mA output to change, which
would affect flow control devices.
Set control devices for manual operation before connecting a HART device to the
transmitter’s primary mA output loop.
