* turn on all devices as the same time * within 10 seconds, while RF LED is blinking, press and hold button on one of the devices * after a second, the new address is randomly generated and sent to all devices. RF LED will blink 3 times to confirm the new address.

* Modbus master, connected to 12 slaves using a pair of WM-1 devices * Modbus master, connected to 10 slaves, organized in two groups * Modbus master, connected to 5 slaves, each one having local WM-1 device
* When the system has two or more separate Modbus lines, they should be configured as separate groups. * Each group has a single master and one or more slaves. * Groups can't talk to each other, but they share the same bandwidth. * Two masters may start transmitting at the same time causing collisions. * To reduce number of missed messages, keep the traffic low.
