# WIZ105SR input

## Question

Asked by samvjt on 2016-02-01 in Serial-to-Ethernet & ConfigTool.

Is any pin when i plug in RJ45 gives me high voltage and unplug RJ45 gives me low voltage? Do i need to change some setting to achieve that ?

Dear samvjt

there is no pin to check the register of link status.
The link status register is supported from W5200 chipset.

Thanks.
