Set Addresses for Modules Without Dials

Some X10 modules don’t have mechanical dials to set their addresses or other options. To configure these types of devices, you need to send commands over the power line.

Some of the X10 modules from Smarthome, Inc. have shed the old-style dial method of setting the module’s house and unit code [Hack #1] . For example, the LampLinc and ApplianceLinc modules, as shown in Figure 1-12, have smooth fronts with no code wheels.

Eliminating the code wheels has some advantages because they can be prone to failure and have a certain air of cheesiness about them, but it’s more complicated than that. By teaching the module to listen for configuration commands over the power line, more options can be supported. That’s exactly what Smarthome has done. With the SmartLinc lamp module, for example, you can set how quickly it dims, its initial brightness level when it’s on, and whether using the switch on the lamp will turn on the module.
