Avitar can be used to configure a PLC device as either a normal PLC station or a <acronym class="acronym">SLAC</acronym> <acronym class="acronym">PEV-PLC</acronym> or <acronym class="acronym">SLAC</acronym> <acronym class="acronym">EVSE-PLC</acronym> station. In doing so, <span class="application">Avitar</span> changes several <acronym class="acronym">PIB</acronym> values at the same time. This section illustrates how to configurat a <acronym class="acronym">PIB</acronym> the same way using the toolkit.
</p><p>
The HomePlug Green PHY Specification refers to the <code class="constant">APCM_SET_CCO.REQ</code> and <code class="constant">APCM_CONF_SLAC</code> primatives in the SLAC protocol description. These are virtual operations to be implemented by the user. In both cases, one must read the <acronym class="acronym">PIB</acronym> from the <acronym class="acronym">PLC</acronym> device, edit the <acronym class="acronym">PIB</acronym>, recompute <acronym class="acronym">PIB</acronym> checksums and write the <acronym class="acronym">PIB</acronym> back to the <acronym class="acronym">PLC</acronym> device. This can be done manually, using <span class="application">Avitar</span>, or in a script, using the Powerline Toolkit as shown below, or programatically, using custom software.
