Terminator resistor setup (JP2~JP9)
In the RS485/422 mode, you can install terminator resistors to match line impedance.
For each signal line Tx (Data), Rx will have to be a separate resistor 120 or 300.
For more details about jumper locations please refer to Figure 2-1

66MHZ_ENABLE pin Setup
The 66MHZ_ENABLE pin indicates to a device whether the bus segment is operating
at 66 or 33 MHz. However, MIC-3612 can only operate at 33MHz limited by FPGA
model. By default, the jumper CN2 is closed, that indicates bus segments are limited
to 33MHz.
