Running a Predefined Voltage/Current Programme
The software allows you to define a series of voltage/current settings for the output, and let them run
automatically. To set up the programme:
Exiting from PC Remote Control Mode
1. Close the remote control software.
2. Disconnect the USB/RS232 cable from the back of the power supply.
You hear a tone from the power supply to indicate that remote control mode is no longer active. The
keys on the front panel are unlocked automatically (this may take a few seconds).
Troubleshooting
If you are experiencing problems, check if the pc's COM port is set up correctly:
•
bits per second: 9600
•
parity bit: none
•
data bits: 8
•
stop bits: 1
•
data flow control: none.
To check the functionality, run this query command via a terminal application such as MTTTY:
*ldn?
This should return the identification information (model name, serial number) of the power supply.
