| **Parameter** | **Type** | **Description** | **Required** | **Default Value** (when not specified) | **Range** |
| name | string | User-friendly device name | Yes | ||
| device\_alias | string | Alphanumeric string to identify a device | Yes | ||
| protocol | Protocol identifier Internal data | Yes | **Internal data** | ||
| scan\_rate\_ms | integer | Update rate | No | 60000 | |
| poll\_delay\_ms | integer | Poll delay | No | 200 |
It is advised to set scan\_rate\_ms to a value greater than 5000 ms as frequent scans may result in a significant overload of the internal data process.
#### The signals section `tag_job` defines the tag job. This can be set to `gpio`, `board`, `netstat`, `gsm`, `led` and `process`. `tag_job_todo` defines the job sub job. This field should address the particular point of interest. There is also an extra trigger parameter which is optional. It allows changing when the signal switches between on and off and is only applicable on LED and GPIO parameters that can be set. The default trigger is value>0. When a **trigger** column is added the trigger can be changed by entering i.e. "value>10". This is useful when mapping a source signal to for example trigger a relay. An example of how to use a trigger is in the example configuration which is attached to this page. [Excel Configuration Example](https://wiki.elseta.com/attachments/33)Digital-input GPIO will only work with Hardware versions 1.4 and above.
Certain GSM parameters will only work if a sim card is inserted.
| **job\_todo** | **Description** | **tag\_job\_todo** | **Description** |
| gpio | ReadOnly parameters | digital-input | If the value is 1 then the digital input pin is high. If it's 0 then the digital-input value is low. |
| rs232-enable | If the value is 1 then rs232 is enabled. If the value is 0 then rs485 is enabled. | ||
| Parameters that can be set. | sim-select | Switch between sim1 and sim2. If the **value** is 0 then sim1 is selected. If the value is 1 then sim2 is selected. | |
| modem-reset | Making this value equal to 1 will reset the modem. | ||
| relay | Making this value equal to 1 will activate the relay. | ||
