2.6 Jumper
1. HRT-710 :
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.
