The Clients can receive their TCMS configuration via DHCP option 210.  
To enable this, create a new DHCP option with ID 210 on the DHCP server. Set the data type to “String” and use the following syntax for the value:

<TCMS-Server-IP-Address>:<AdditionalApiPort>

The additional API port is optional. It can be configured in the  basic settings  of the TCMS.

On the Thin Client, the required TCMS settings are automatically applied by the setup wizard during initial startup. Alternatively, the settings can be configured manually. To do so, enable the option  
Remote-Administration → TCMS Settings → obtain via DHCP .

Once the TCMS settings are configured, the Thin Client will automatically be added to the *Temp Group* during its first login to the TCMS.

• Examples

Under “Additional Options”, add a new entry via “Advanced” using the following values:

• Number: 210  
• Type: String  
• Value: "<TCMS-Server-IP-Address>:<AdditionalApiPort>" (Port optional, include quotation marks)

Save your changes with “Save”.
