# WIZ110SR DTR signal

## Question

Asked by ggroke on 2016-01-29 in Serial-to-Ethernet & ConfigTool.

I have a WIZ110SR which is suppose to communicate with a serial device that uses DTR signal.

However, it doesn’t work at all. Does WIZ110SR implements DTR signal? Or can it be done in some way?

Dear ggroke

Sorry, DTR signal is not supported in WIZ110SR.
DTR signal is supported in WIZ100SR customization version according to PO volume.
If you want to that, Please conact to sales. (sales@wiznet.co.kr)

Thanks.
