Interface Number of RS485 ports 1
Other Supply voltage 11.5...27.5 V DC Dimentions 45x42x14 mm

RS485 INTERFACE ADAPTER

This module is designed for interface adjustment between the devices which have the RS485 interface and the Smart Home system. The module has an internal 120Ω terminator resistor.

Features

• Supported protocols:
  • ModBus RTU
  • DMX512
  • Custom protocols
• 1200 – 115200 baud rate

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. 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:

• all connectivity work must be carried out with the power turned OFF;
• use appropriate tools and personal protection against electric shock;
• do not use damaged cables, wires and connectors;
• avoid folding the cables and wires;
• 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;
• do not use the power socket with poor contacts to connect;
• do not exceed the load limit parameters specified in the manual;
• 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.

When the power is on, NEVER:

• connect/disconnect the connectors;
• open modules and sensors.

HW settings

Name	Type, range	SUBID	Default	Description
cfg	string	98	9600/8N1	cfg='SPEED/BPS', where SPEED – baud rate [1200..115200]; B – data length [7,8]; P – presence and type of parity bit [N(No parity),E(Even parity),O(Odd parity)]; S – stop bit length [1, 1.5 or 2]. Example: 1hw="cfg='9600/8N1'"
[Protocol]	string	98	—	Protocol setting is described by protocol parameter. The following protocols are supported: 'modbus', Modbus protocol, at the end of redirection the checksum CRC16(Modbus) is added; 'dmx', DMX protocol; 'CO2' for connecting Larnitech CO2 sensors; 'salda' for connecting Salda ventilation. Example: 1hw="cfg='9600/8N1' modbus"
echo	on; off	98	'off'	For settings check out and testing echo parameter can be used. Module echo-reply can be turned on or off with the help of this parameter. Echo parameter value: 'off'; 'on'. Example: 1hw="cfg='9600/8N1' echo='off'"
