RS485-Termination Jumpers
Connector type
IDC8 pin header 2.0 mm
Matching part
2.0 mm jumper
Use 2 mm jumpers to terminate lines correctly.
There are two jumpers COM1 and COM2, respectively.
The RS485 termination jumpers are located at the
top of the printed circuit board, see chapter 2.2
When the jumper is set, the differential pairs
are terminated with 120
Ω
between them.
(E.g. RX+ and RX-, on the right picture)
Additionally, positive/negative receive lines are pulled up/down with 10k
Ω
to 5V/GND in order to protect the
transceivers of the Cool LiteRunner-86DX from over voltages.
It is recommended to protect the ports of the external device in the same way!
