JP3, JP5 - External Power Enable/Disable Selector - JP3 is used to set pin #9 of DB9

connectors S1-S4 to either the RI (Ring Indicator Signals) or the 5V/12V DC Power

(selected by JP4). JP5 performs the same function for DB9 connectors S5-S8. When

the jumper is set to the “P” position, it will output the DC power over pin #9; if set to

the “D” position, pin #9 will be connected to the normal RI signal, based on the RS232

standard.

JP4 - Power Source Selector - Used to select DC power for pin #9 of the DB9

connectors. This can be set from PCI Express 12V or 12V (or 5V) from the 4-pin auxilliary

power connector.
