To view/edit basic/advanced parameters for a single device

Review or edit basic and advanced parameters on one device record.

Review or update device parameters from the Device Details page.

Before you start

Confirm that:

• you selected the correct device
• you know which application or parameter set you need to change
• you are ready to save the update and schedule a parameter download if needed
• the selected application version matches the parameter change

Open device parameters

1. Go to Verifone Central → Device Management → Devices.
2. Open the target device.
3. Go to Device Details → Details → Parameters.

Parameter levels

Parameter management supports:

• basic parameter configuration with two levels
• advanced parameter configuration with five levels

A warning message is displayed when there is an error in the uploaded VPFX file. Select the Restore Default button to revert to the old configuration.

Edit parameters

1. Review the current parameter values.
2. Update the required basic or advanced parameters.
3. Save the changes.

Capture the existing value before changing it. Change only the parameters required for the task. This makes a later review or correction unambiguous.

Stop if the device, application version, or parameter level is unexpected. Review the device record before saving.

The edited parameters can be scheduled for download using the option sequence Actions > Download Schedule > Parameters Only.

Verify the result

After you save the update, confirm that:

• the new values appear in the parameter view
• the correct application or parameter level was updated
• a Parameters Only download is scheduled if the device must receive the change
• the saved value matches the intended value on the correct parameter level
• the device identifier matches the scheduled parameter download
