| ------------ | -------------------------------------------------------------------------------------------------------------------------- |
| `RefreshPed` | Updates the terminal information. Triggers a PED state callback from which you can query the state using `GetDeviceState`. |

## Parameters

| Name      | Type | Required                                                                                    | Description                                                                                                                                                                                                                                 |

| `retries` | Int  | ![-white\_check\_mark-](/user/data/smileys/emoji/white_check_mark.png "-white_check_mark-") | Number of times to retry refreshing the PED state. If you have multiple POS systems connected to a single PED, there may be an active transaction on the device which would block the request. Set this to a high number to avoid blocking. |
