RX01/LX01 SERIES RF POWER SUPPLY OPERATOR’S MANUAL

ANALOG INTERFACE CONNECTOR PIN LIST

PIN SIGNAL NAME DESCRIPTION

4 PWR/VLT* Power or Voltage leveling mode select. TTL – compatible input

with internal pull-up resistor.

An open circuit or TTL “high” signal applied to pin 4 selects the

power supply’s internal power sensor for power regulation.

A contact closure between pin 4 and pin 16 or a TTL “low” signal

applied to pin 4 selects forward power regulation based on an

external feedback signal (FEEDBACK signal - Pin 12).

Refer to the controls section of the operator’s manual for

detailed instructions on how to configure and use this mode.

This signal is active only in “Analog” control mode.

5 SLAVE* Selects internal oscillator/exciter or external oscillator/exciter

(Slave Mode) as frequency source operation. TTL – compatible

input with an internal pull-up resistor.

A contact closure between pin 5 and pin 17 or applying a TTL

“low” signal to pin 5 selects external frequency source (Slave

Mode) operation. The external frequency source is connected

to the “CEX IN” connector on the rear panel.

An open circuit or TTL “high” applied to pin 5 selects the power

supply’s internal oscillator/exciter as the frequency source.

This signal is active only in “Analog” control mode.

6 GATEN* Selects Continuous Wave (CW) or Pulse Operation. TTL –

compatible input with an internal pull-up resistor.

A contact closure between pin 6 and pin 17 or applying a TTL

“low” signal to pin 6 selects pulse operation. Apply the external

pulse train to Pin 7.

Applying a logic level high to this pin or allowing this pin to float

selects continuous wave (CW) operation.

7 GATE External Pulse Train input. Toggles output power between

setpoint value and 0 Watts. TTL - compatible input with internal

pull-up resistor.

An open circuit or TTL “high” signal applied to pin 7 holds the RF

output to the setpoint level.

A contact closure between pin 7 and pin 17 or a TTL ‘low” signal

applied to pin 7 switches the RF output power to 0 Watts.

Active when pin 6 (GATEN*) is in a TTL “low” state.

8 RFENABLED* RF output status signal. Active low, open collector output.

24VDC, 15mA maximum current sink, 150mW maximum power

dissipation.

Signal output is 0V (low) for an RF on condition; signal output is

“open” for an RF off condition.
