8.4.
The module supports two networking modes: Normal and Slave.
In normal mode, the module can talk to any other module. In slave mode, the module can talk to
normal-mode modules, but cannot transmit to or receive from other slaves.
Slave mode is selected by writing 0x00 to this register. The default network mode is 0x01
(Normal Mode).
8.5.
When a byte is received by the UART, the module will start a timer that will countdown every
millisecond. The timer is restarted when each byte is received.
If the timer reaches zero before the next byte is received from the UART, the module begin
transmitting the data in the buffer. Normally, this timeout value should be greater than 0x01 and
greater than one byte time at the current UART data rate. If the timeout value is set to 0x00, the
transmit wait timeout will not operate, and a full buffer will be required for transmission. When
configured this way, the data will be sent only when a full MTU has been received through the
UART. The default setting for this register is 0x10 (~16ms delay).
8.6.
Modules can be grouped into networks. Although only modules with the group ID will be able to
talk to each other, modules in different groups but on the same channel will still coordinate
transmissions through the CSMA mechanism. Valid values for this register are 0 to 127. The
default group setting is 0.
