2. Hardware Installation
Users may need to make a hardware setting before the application.
The detailed illustration is as below :
[ Step1: Connect Serial port & Set FW Operation Mode ]
Connect the serial port of the I-7570 to PC and set the dip-switch on
the back of I-7570 to the “Normal” position. Then turn on the I-7570
module power.
[ Step2: Check the LED Indication I-7570 ]
Check the PWR LED of I-7570 if it is always on. If yes, it means I7570 is working in the
“Firmware Operation” mode.
[ Step3: Enable or Disable the Terminator Resistor ]
There is a Jumper (JP4) at the I-7570 module, shown in Figure 2-1.
The jumper can provide HART network with 250 Ω (1/4 W) load resistor.
When the pin 1&2 of JP4 is connected, the resistor will connect to HART
network. When the pin 2&3 ofJP4 is connected, it will disconnect the
resistor from HART network. By default, the pin1&2 of JP4 is connected.
