PC Software for PeakTech Power Supply Models

Drivers

The P 15xx series power supplies communicate using a UART Bridge VCP Driver. If this driver is not installed, it can be downloaded from the Silicon Labs website. Models P 1885 and P 1890 do not require an additional driver and are typically detected as standard serial USB devices by the operating system.

Software Configuration

Follow these steps to configure the software:

• Open the pcsc folder and start the pscsMult.bat application.
• Click the [Add Button] to set up preferences for connecting to your device.

Finding the Port Number:

To find the correct port number for your power supply, use Windows' Device Manager. For models connecting via RS485, an additional RS485 Device ID will be required.

Adding a New Connection:

Fill in the required fields in the "Add" popup window and click the [Save Button] to establish a new connection.

The "Add" connection window typically includes fields for:

• Connection Name: e.g., USB_1
• Description: (Optional)
• Connection Type: e.g., USB
• COM Port: (e.g., COM5, identified via Device Manager)
• RS485 ID: (For RS485 connections)

Connecting to the Device:

You can select a connection by its icon or double-click the configured connection window to access the user interface of the specific power supply. Multiple connections can be managed using the [Add Button], [Edit Button], and [Delete Button].

Once the software successfully connects to your device, the readings will be displayed. The main interface shows:

• Current Voltage, Current, and Power readings.
• Output status (On/Off).
• A graphical representation of Voltage and Current over time.
• Options to configure Wave Form Generator descriptions.

The interface also includes controls for setting Voltage and Current limits (UVL/UCL) and sampling rates.

Software Operating Modes

The software offers several operating modes accessible via separate tabs:

• External Timed Program
• Internal Preset Memory
• Data Log
• Settings
• Device Calibration

External Timed Program

This mode allows for the creation and execution of timed programs. After setting the desired voltage, current, and time values for each step, you must press Enter and activate the output. The values will turn green, and the [Run Button] will become available.

The "External Timed Program" table displays columns for Step, Voltage(V), Current(A), Time, and Output status (checkboxes indicating if output is active for that step).

The interface also shows the current running cycle and remaining time.

Internal Timed Program (for P 1885, P 1890)

Models P 1885 and P 1890 feature an additional mode: "Internal Timed Program". This program runs entirely on the power supply and is managed internally.

Important Notes:

• After completing the program configuration, click [Save to PS Button] to ensure the data is stored correctly on the power supply.
• Setting the time to 00:00:00 is considered invalid. This setting has no operational meaning and will cause the program to stop at that step, disconnecting the output.

The "Internal Timed Program" interface displays a table with steps, Voltage(V), Current(A), and Time. It also includes fields for program description, cycle settings, and buttons like [Read From PS Button] and [Save To PS Button].
