JP2- External Power Enabler: There are 4 jumpers that control the pin-9
signal of the 4 serial port DB9 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 JP3 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 JP3:
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.
1. Turn the system power OFF before installation!
2. Remove the chassis cover from your computer
3. Locate an unused PCI Express slot (typically white and smaller)
and remove the corresponding slot cover from computer chassis.
4. Plug the I/O card to the unused PCI Express expansion slot and
attached the I/O card bracket to the computer chassis screw.
5. Installing the supplied DB44-to-4XDB9 octopus cable and serial
cables to your serial devices.
6. Put the chassis cover back on the computer.
Note:
PLEASE DO NOT LET WINDOWS AUTO SEARCH THE DRIVERS ON THE CD, it
will cause problems because the INF files will be conflict in this case.
Instead, please browse to the correct location (folder) manually to
