3.2 Operation through Optional Interfaces
3.2.1 25 ‐ pin Analog Interface
PIN NAME TYPE DESCRIPTION
1 MAX POWER (E) DO Emitter side of isolated transistor switch. (See Note 1.)
Transistor ON ‐ indicates max reverse power.
2 REFLECTED POWER
(+)
AO A linear DC voltage that represents the reflected power
output level.
0 V = 0 W, 1 V = 20 W
3 FORWARD POWER
(+)
AO A linear DC voltage that represents the forward power
output level.
0 V = 0 W, 1 V = 75 W
4 RF ON/OFF CONTROL
(+)
DI A voltage between this and Pin 17 will turn RF power ON.
Leaving it open or applying zero voltage will turn RF
power OFF.
The nominal voltage to turn RF ON is selectable between
+5 V or +24 V (default) via a jumper. Input should not
exceed 30 VDC.
5 POWER SET POINT
(+)
AI A linear DC voltage to set the output power level.
0 V = 0 W and 1 V = 75 W. Input impedance is 100 k Ω
balanced differential to ground.
6 NOT USED —
7 RF ON (E) DO Emitter side of isolated transistor switch. (See Note 1 )
Transistor ON—RF ON. Transistor OFF—RF OFF.
8 ANALOG REMOTE
ENABLE
DI Ground referenced logic input. (See Note 2.)
LOW ‐ Selects analog remote control mode.
HIGH (or OPEN) ‐ Disables analog remote control mode.
9 OVERHEAT (E) DO Emitter side of isolated transistor switch for Pin 22.
10 INTERLOCK (+) — This pin should connect to Pin 23 to complete the
interlock chain.
If the interlock chain is broken, the power supply will be
disabled.
11 LEVELING SELECT DI Ground referenced logic input. (See Note 2.)
LOW (or OPEN) ‐ Selects forward ‐ power leveling.
HIGH ‐ Selects an alternative power ‐ leveling mode.
12 LOAD POWER (+) AO A linear DC voltage that represents the load power output
level.
0 V = 0 W, 1 VDC = 75 W
13 +12 VDC — User voltage for interface purposes. Rated 10 mA max.
14 MAX POWER (C) DO Collector side of isolated transistor switch for Pin 1.
