Module Configuration

The 250 Series module contains several registers that control its

configuration and operation. The module’s default settings allow it to

operate out of the box without any changes; however the registers allow

the link to be customized to better suit the application if necessary. The

Volatile memory is quick to access, but it is lost when power is removed

from the module. Non-volatile memory takes longer to access, but is

retained when power is removed.

All of the configuration settings have registers in both types of memory.

The settings are read from non-volatile registers on power up and saved in

volatile registers. The values in the volatile registers are used during normal

operation since it is faster to read and write the volatile memory locations.

There are commands to read and write both locations.

Figure 21 shows the volatile read-only registers. Figure 22 shows the

volatile read and write registers. Figure 23 shows the non-volatile read-only

registers. Figure 24 shows the non-volatile read and write registers.

Warning: Modules that are not configured in the same way will not be

able to communicate reliably, causing poor performance or outright

failure of the wireless link. All modules in a network must have compatible

configurations to ensure interoperability.
