Does GS-EDRV100 support GS4-4040

[Saturn_Europa1]

The EDRV100 manual says that it supports GS4:  The GS-EDRV100 is designed to work with legacy GS1, GS2, GS3, and GS4
series drives.

But Automation Direct has this answer:

The GS-EDRV100 uses predefined Modbus addresses for the Command Word and Status Addresses which match those for the legacy GS1, GS2 and GS3 series.

There is some overlap with the modbus addresses of GS4 but they are not the same.  Therefore, we do not recommend attempted use of the GS-EDRV100 with the GS4.

The GS4 series offers the following ethernet communication cards:

GS4-CM-MODTCP
GS4-CM-ENETIP


Who is right?

What are you using as a controller?  If it's a BRX then why bother with an EDRV100?  The built in MODBUS scanner will do it better and easier than trying to fiddle with a bunch of individual statements.
