This is a RS232 vs RS485 asynchronous bidirectional convertor, which features electromagnet isolation. The internal TVS bidirectional transient suppression diode and detonator to protect the device from unstable working.

Package Includes - 12V Power Adapter and Male to Female RS232 DB9 Cable

• Stable transmission on rate of 300~115200bps
  
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• 1200m Long Distance Transmission
• Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
• Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
• Integrates optional RS485 output terminal 120R resistor, enabled/disabled via switch
• DC-005 power jack, allows 6V~36V DC wide range input, suits different application situations
• 3x LED indicators, easy to check the operating status: power, transmitting, and receiving
• Aluminium alloy enclosure with sand blasting and anodic oxidation, solid and durable
