Internal Connector and Jumper Setting
The COM1 and COM2 are designed for multiple proposes. Using JP5 (COM1) or JP6
(COM2) is to select RS485 terminator resistor. JP7 is used to select 3VSB /3.3V
voltage with PCIE mini card module (See a PCIE mini card module specification.)
JP2 is used to clear CMOS data, and other connectors are reserved for other
usage.
