2.7 Jumper
There are four Jumpers (JP5~JP8) at the GW-7557 module, as shown in
Figure 14
.
These jumper can provide HART channel with 250
Ω
(1/4 W) resistor. When the pin
1&2 of JP5 is closed, the resistor will connect to HART channel 0. When the pin 2&3
of JP5 is closed, it will disconnect the resistor from HART channel 0. By default, the
pin1&2 of JP5 is closed. Please refer to section 2.3.3 HART connection for detail.

PS:
The relation between jumpers and
HART channels is shown in below:
JP5 => Channel 0
JP6 => Channel 1
JP7 => Channel 2
JP8 => Channel 3
