Advantech WISE-4250

The WISE-4250 series is an Ethernet-based wireless IoT device that is compatible with various I/O and sensors. It is integrated with IoT data acquisition, processing, and publishing functions and can communicate with different WISE devices via the P2P function. Wireless watchdog timer, smart roaming, timestamped data logger, and data recovery functions can enhance connection quality and mitigate the risk of data loss. Data and connections can also be protected via the WPA3/TLS1.3 encryption protocol. It can be accessed via PC and mobile devices and data can be published to diverse types of clouds

IEEE 802.11 a/b/g/n/ac 2.4/5GHz Wi-Fi with AP Mode

The Wi-Fi interface is easily integrated with wired or wireless Ethernet devices, users only need to add a wireless router or AP to extend existing Ethernet network to wireless. The limited AP mode enables the WISE-4250 to be accessed via other Wi-Fi devices directly as an AP.

Smart Roaming

This function help WISE-4250 series communicate and connect to surrounding AP much more flexibly and effectively to prevent long disconnection idle time and setup more stable network. 802.11 k/v/r are also supported to help on better signal strength management in advance and faster connection time.

Data Logger and Recovery

The WISE-4250 can log 10000+ data with timestamp and system log normally or if there?s any wireless dis-connection gap. Once the memory is full, users can choose to overwrite the old data to ring log or just stop the log function. This function helps no missing data and help tracking complete data.

Peer to Peer (P2P)

This function allows modules to send signals to each other remotely (up to 16 devices). These signals can be sent periodically or triggered by a change in status (e.g., an AI/DI input change triggering a DO output). It supports two modes: a basic mode for a single target module/channel and an advanced mode for multiple target modules/channels. By utilizing P2P technology, modules can communicate directly, effectively reducing latency and improving response time. Furthermore, data transmission uses the UDP protocol and can be encrypted with AES-128 to ensure communication security.

HTML5 Web Configuration Interface

All the configuration interfaces are applied in web service, and the web pages are based on HTML5, so users can configure the WISE-4250 without the limitation of OS/devices. You can use your mobile phone or tablet to directly configure the WISE-4250.

RESTful Web Service with Security Socket

WISE-4250 also supports IoT communication protocol, RESTful web service. Data can be polled or even be pushed automatically from the WISE-4250 when the I/O status is changed. The I/O status can be retrieved over the web using JSON. The WISE-4250 also supports HTTPS which has security that can be used in a Wide Area Network (WAN).
