There is a Jumper (JP4) at the I-7570 module, as shown in Figure 2-4.
The jumper can provide HART network with 250 Ω (1/4 W) resistor. When
the pin 1&2 of JP4 is closed, the resistor will connect to HART network.
When the pin 2&3 of JP4 is closed, it will disconnect the resistor from
HART network. By default, the pin1&2 of JP4 is closed.
