REMOTE CONTROL

Remote Control Setup
All the models with the suffix “P”, such as KA3003P,KA3005P, KA6002P, etc. can be connected to the PC through interfaces USB/RS232 on the back of the machine and controlled by the remote control.

COM setting
Set up the COM port inside the PC according to the following list.

• Baud rate: 9600
• Parity bit: None
• Data bit: 8
• Stop bit: 1
• Data flow control: None

Functionality check Run this query command via the terminal application such as MTTTY (Multi-threaded TTY).

*IDN?
This should return the identification information:
Manufacturer, model name, software version.
KORAD KA3003P Vx.xx

REMOTE CONTROL PROCEDURES

Entering the Remote Control Mode

1. Connect the USB cable.
2. The power supply will automatically connect. After normal connection,there will be a tweet from the power supply itself.
3. The panel buttons are locked, so the power supply can only controlled by the computer.
   NOTE: KORAD software must be installed first.

Exiting from the Remote Control Mode

1. Close the remote control software.
2. Disconnect USB from the back.
3. The power supply disconnects; a tweet from the beep with the hint that the remote control is over.
4. The power supply automatically comes into the panel control mode.
