# multi socket TCP IP

## Question

Asked by phuctruong on 2017-11-29 in Serial-to-Ethernet & ConfigTool.

I’m using WIZ550SR module for my project. I have a question for you:

- When I config this module run client mode can I create two (or more ) socket to connect to server via two (or more) port at the same time? See the picture below

I contacted Mr Kit Wan (kitwan@wiznet.hk), he said: customized firmware WizSE module W5500S2E-S1 which can below connect up to 4 TCP connections.

I already have WIZ550S2E modules (<http://wizwiki.net/wiki/doku.php?id=products:wiz550s2e:wiz550s2eds_en>), Can you send for me the customized firmware version of W550S2E which support multi socket handing function?

I will use one of two module: W5500S2E-S1 or WIZ550SR for my project.
Can you help me to choose a S2E module which support connect 2 server socket is the best.

Thank you so much!
