Notes on J3 Signals
COM1 – COM4	The signals on these pins are RS-232 level signals and may be
	connected directly to RS-232 devices. The pinout of these signals is
	designed to allow a 9-pin male IDC connector to be crimped onto the
	corresponding ribbon cable wires to provide the correct pinout for a PC
	serial port connector (DTE).
LPT1	The signals on these pins comprise a standard PC parallel port. The
	pinout of these signals is designed to allow a 25-pin female IDC
	connector to be crimped onto the corresponding ribbon cable wires to
	provide the correct pinout for a PC parallel port connector.
Keyboard, Mouse	These are PS/2 signals for keyboard and mouse.
Clk	Clock pin; connects to pin 5 of the PS/2 connector.
V-	Power pin; connects to pin 3 of the PS/2 connector.
Data	Data pin; connects to pin 1 of the PS/2 connector.
V+	Power pin; connects to pin 4 of the PS/2 connector.
	Pins 2 and 6 on the Mini-Din-6 PS/2 connectors are unused.
Utilities A
+5V Out	This pin is a switched power pin that is turned on and off with the ATX
	power switch or with the +5V input.
Speaker Out	The signal on this pin is referenced to +5V Out. Connect a speaker
	between this pin and +5V Out.
IDE Drive LED	Referenced to +5V Out. Does not require a series resistor. Connect
	LED directly between this pin and +5V Out.
Power LED	Referenced to +5V Out. Does not require a series resistor. Connect
	LED directly between this pin and +5V Out.
Utilities B
Reset-	Connection between this pin and Ground will generate a Reset
	condition.
ATX Power	When ATX is enabled, a momentary contact between this pin and
	Ground causes the CPU to turn on, and a contact of 4 seconds or
	longer will generate a power shutdown. ATX power control is enabled
	with a jumper on jumper block J10 (see page 14).
KB Lock	When this pin is connected to Ground, the keyboard and mouse inputs
	are ignored.
IR RX, IR TX	IrDA pins. Can be connected directly to an IrDA transceiver.
+5V In	Connected to +5V input power on J11 (see page 9). This pin is not
	switched by ATX control. This pin is provided for auxiliary use such as
	front panel lighting or other circuitry at the user’s discretion.
