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

As well as supporting Modbus/TCP, the 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).
