Common Features

• Ethernet or WiFi interface for access via an internal website and standard communication protocols.
• Ethernet versions support Power over Ethernet (PoE), eliminating the need for an external power supply, though an AC adapter can also be used.
• WiFi parameters can be configured via a USB interface.
• Internal memory and real-time clock for storing measured data, including timestamps, which is automatically sent when communication is restored after an interruption.
• Housed in an elegant yet robust metal box suitable for DIN rail mounting. The box includes clear descriptions and LED indicators for easy commissioning.
• Data can be displayed, stored, and analyzed using the Wix program.

Communication Options

PAPAGO devices offer various communication options depending on the interface used. Control is possible via a web interface or Windows software. Machine data can be read using standard methods like Modbus TCP, HTTP GET (with encryption), e-mail, SNMP, XML, and Spinel. User control is available through a web interface or Wix software.

Communication Protocols Supported:
