Serial configuration by inverted RS232 at 3V CMOS level

Inexperienced users of ISM band radio modules often

require a totally transparent interface. This can require

considerable processing power, and buffer memory,

to be provided in the radio device.

The more experienced user, on the other hand, may

not want to write a raw radio interface, but desires a

module that gives more control over the datastream

than a 'beginners' solution.

The PL radios represent such a compromise solution.
