==SERIAL PORT ADAPTER==&lt;br /&gt;
&lt;br /&gt;
This module is designed for interface adjustment between the devices&lt;br /&gt;
which have the UART interface (TTL levels) and the Smart Home system.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;caution&amp;quot;&amp;gt;&lt;br /&gt;
CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment.&lt;br /&gt;
To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:&lt;br /&gt;
*all connectivity work must be carried out with the power turned OFF;&lt;br /&gt;
*use appropriate tools and personal protection against electric shock;&lt;br /&gt;
*do not use damaged cables, wires and connectors;&lt;br /&gt;
*avoid folding the cables and wires;&lt;br /&gt;
*do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;&lt;br /&gt;
*do not use the power socket with poor contacts to connect;&lt;br /&gt;
*do not exceed the load limit parameters specified in the manual;&lt;br /&gt;
*the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.&lt;br /&gt;
When the power is on, NEVER:&lt;br /&gt;
*connect/disconnect the connectors;&lt;br /&gt;
*open modules and sensors.&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;

*P – presence and type of parity bit [N(No parity),E(Even parity),O(Odd parity)];&lt;br /&gt;
*S – stop bit length [1, 1.5 or 2].&lt;br /&gt;

*'modbus', Modbus protocol, at the end of redirection the checksum CRC16(Modbus) is added;&lt;br /&gt;
*'dmx', DMX protocol;&lt;br /&gt;
*'CO2' for connecting Larnitech CO2 sensors;&lt;br /&gt;
