Table 4-1.User Port 25-Pin APEX Standard Pin Descriptions (Continued)

Signal	Return	Name	Signal	Description
Pin	Pin		Type
4	17	RF PWR ON	Digital	When a positive voltage between
			input	4 and 30 V is applied to this pin
				RF output is enabled. Once the
				output is ON, a voltage of 1.5
				Vdc or less disables the RF
				output.
				See Wiring Diagram 4-5.
				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.
5	18	SETPOINT	Analog	This pin linearly controls the RF
			input	output of the generator.
				0 to 10V = 0 to maximum rated
				power output as defined by
				configuration PIN position 2 in
				Table 1-1.
				See Wiring Diagram 4-3.
				Note: Setpoint must be greater
				than 1% of full rated
				output before unit will
				deliver power.
