2.6 Jumper

There is a Jumper (JP4) in the HRT-710 module shown as Figure 13. The
jumper can provide HART bus with 250 Ω (1/4 W) resistor. When the pin 1&2
of JP4 is closed, the resistor will connect to HART bus. When the pin 2&3 of
JP4 is closed or JP4 without jumper connected, it will disconnect the resistor
from HART bus. By default, the pin1&2 of JP4 is closed. Please refer to
section 2.3.4 - HART connection for detail.
