# Wiznet config Tool107 Version 1.4.4.1 Compatibility

## Question

Asked by Dave2010 on 2026-06-03 in Ethernet Chips.

Wondering if the Wiznet config Tool107 Version 1.4.4.1 would be compatible with the new Wiz750SR TTL. I have used this tool to configure the old Wiznet 107SR but that is obsolete, so we are using the new Wiz750SR TTL now. I would like to know if the old config tool can configure the new devices.

The legacy Config Tool (Tool107 v1.4.4.1) does not support the WIZ750SR series, including the WIZ750SR-TTL.

For configuration and management of WIZ750SR devices, please use the latest WIZnet Configuration Tool available at the link below:
