Signal	Return	Name	Signal	Description
Pin	Pin		Type
4	6	RF POWER	Digital	RF output is enabled when a 4 to
		ENABLE	input	30 V input (pin 9, RF ON BIAS,
				can be used as a voltage source)
				is present on this pin.
				Note: The interlocks must be
				satisfied and the setpoint
				must be within the Output
				power range before unit
				will deliver power. See
				Table 3-3. on page 3-6 for
				the Output power range
				specification.
				See Wiring Diagram 4-17.
5	6	FORWARD/LOAD	Analog	This analog signal provides a
		POWER SETPOINT	input	linearly scaled control of the
				forward or load output power
				depending on the regulation
				mode (1 V per 1 kW output
				power).
				See Wiring Diagram 4-16.
				Note: The interlocks must be
				satisfied and the setpoint
				must be within the Output
				power range before unit
				will deliver power. See
				Table 3-3. on page 3-6 for
				the Output power range
				specification.
6		SIGNAL COMMON	Chassis	This pin is Signal Common. Also
			ground	connected to Apex generator
				chassis ground.
7	6	RF ON STATUS	Digital	+ 5 Vdc on this pin represents
			output	RF ON.
				See Wiring Diagram 4-18.
8	6	EXTERNAL BIAS	Voltage	+15 Vdc provided to the User
			reference	port through a 5.62 kΩ resistor.
				See Wiring Diagram 4-20.
