JP2- External Power Enabler: There are 4 jumpers that control
the pin-9 signal of the 4 serial ports connectors (S1~S4)
respectively. If the jumper(s) is at the “DIS” position (factory
default), the pin-9 was connected with the RI signal as standard
RS232 definition. If the jumper is at the “PWR” position, the pin-9
was connected with a power either from PCI Express slot or
from Aux Power connector (J7). The power source is controlled
by JP4 jumper (see the following section).
JP3- External Power Selector: The pin-9 of the serial port
connector will be supplied with DC5V or DC12V. There are 3
sources depends on the jumper’s position of the JP4:
AUX5V: DC5V, from J7, an optional power cable is required.
AUX15V: DC12V, from J7, an optional power cable is
required.
PCI12V (factory default): DC12V, from PCI Express golden
finger, no cable is required.
