# Input source (https://docs.pulsarml.com/guides/settings/input-source)

Check whether each machine's production comes from a sensor or is entered by hand, and which count it uses.



The **Input Source** tab shows, for each machine with production, where its production data comes from: counted automatically by a Pulsar sensor, or entered by people. To open it, go to **Settings** → **Production** and click the **Input Source** tab.

<Screenshot id="input-source-table" alt="Production settings on the Input Source tab, titled Input source with the subtitle Where each machine's production data comes from. At the top right, a Search field and the Showing All filter. Below, a table with the columns Machine, Subscription, Input source and Production Input: every row shows an OEE Pro badge, Sensor with a blue LIVE badge, and Total with a lock icon." width="1440" height="700" />

## The columns [#the-columns]

* **Machine**: the machine's name.
* **Subscription**: the machine's plan, **OEE Pro** or **OEE Lite**. The list shows only machines on one of these two plans.
* **Input source**: **Sensor** with a **LIVE** badge when a sensor counts the machine's production, or **Manual** with a **FORM** badge when people record it, on the Real Time card or in the [mobile app](/guides/mobile-app/production-lite).
* **Production Input**: the count Pulsar takes as the machine's production, **Total** or **Correct**.

Click the **Machine** or **Subscription** header to sort the table by that column.

## Who can change the production input [#who-can-change-the-production-input]

The lock next to a **Production Input** value means you can't change it here. Hold the pointer over the lock to see why:

* On **OEE Pro** machines the value comes from the sensor: *This is driven by a sensor and can't be manually overridden*. Nobody can change it.
* On **OEE Lite** machines, only super-admins can change it, choosing **Total** or **Correct** from a drop-down in the cell. Everyone else sees the value with a lock and the message *Only super-admins can edit this*.

## Find a machine [#find-a-machine]

* Type in **Search** to show only the machines whose name contains that text.
* Click **Showing All** to open **Filter by**, with a switch for **OEE Pro** and one for **OEE Lite**. Turn one off to hide those machines, or use **Hide all** and **Show all**.

The list also follows the machine group selected in the top bar.
