# WIZ750SR-105 need access to more GPIO

## Question

Asked by PaulPlasma on 2022-04-29 in Serial-to-Ethernet & ConfigTool.

Hi,
I need more than 4 TTL outputs, preferably a total of 6 or 7. The pinout pictures hint at more GPIO but there is no documentation of any commands to take control of them. Is there a more extensive command document available?
Thanks
