<Zone ID> | Is a number from 00 to 99, sending "00" selects all zones. |
| The maximum number is 99. |
| Zone ID is factory set at "0", but can be reassigned. |
<Product ID> | For the XT1, the factory default setting for product ID is 10 |
<Command> | Is 1 to N, N may be in one or multiple digits as defined in the first column in the |
| table below |
<Parameter1> | None, or is 1 to N, N may be in one or multiple digits as defined in the |
| "Parameter1" column below |

<Zone ID> | If multiple T118 tuners are used in one application, the Zone ID of each tuner |
| shall be reassigned with a unique number. |
In this way each tuner can be controlled individually via the RS232 port. Use command 14 in the following list to program a new Zone ID.
