2.4.2 37-pin Analog I/O Interface (ENI P/N: 1050-295)
The 37-pin Analog I/O Interface is optically insulated from the
generator at the interface board interconnect point. Therefore, to use
this interface card, the customer system needs to source power to the
interface board on Pins 36 and 37.
Pin Name Type Description
1 MAX POWER (E) DO Emitter side of isolated transistor switch. (See
Note 1)
Transistor ON - Indicates a max. reverse power
or max. current limit.
Transistor OFF - No limit reached.
2
REFLECTED
POWER (+)
AO A linear DC voltage that represents the reflected
power output level.
0 V = 0 W and the max. value is adjustable
between 0 and 12 VDC.
Typically calibrated to 10 VDC = Maximum
Reflected Power Limit.
3 FORWARD
POWER (+)
AO A linear DC voltage that represents the forward
power output level.
0 V = 0 W and the max. value is adjustable
between 0 and 12 VDC.
Typically calibrated to 10 VDC = Maximum Rated
Power.
4 RF ON/OFF
RETURN
DI Signal return for Pin 29.
5
POWER
SETPOINT (+)
AI A linear DC voltage to set the output power level.
0 V = 0 W and the max. value is adjustable
between 0 and 12 VDC.
Input impedance is 100 k ohms balanced
differential to ground.
6 No Connect N/A NONE
7
GENERATOR
READY (E)
DO Emitter side of isolated transistor switch. (See
Note 1)
Transistor ON - GENERATOR READY
Transistor OFF - GENERATOR NOT READY
Signal Definition:
Generator Ready = interlock chain complete (see
Pins 10 & 35) as well as no present generator
overheat condition.
DI = Digital Input DO = Digital Output AI = Analog Input AO = Analog Output
