Interface MK2 or MK3 USB?

I'm trying to find out if I need a MK2 VE Bus to USB or MK3. I have tried to connect to my Victron Multiplus Pheonix Inverter Charger 24/1200/25 with Firmware No. 1817xxx.HEX using a MK3 adaptor with VEConfigure 3 but when making port selection receive 'MK 3 Detected (VE. Bus Device Only). and will not connect to inverter. I'm thinking I may need the MK2 as MK3 does not appear to be working?

I have searched through relevant posts, but there seems to be conflicting opinion as to which VE Bus to USB will work. Any advice would be appreciated.

If the MK3 does not work you need to use the MK2.

Your old Phoenix MultiPlus uses the old VE.9bit protocol and the newer MK3 can only "talk" VE.bus.

An older product with 18xxyyy firmware is not VE.Bus it is VE.9bit and it won't work with a MK3. You'll need a MK2 to configure a 18xxyyy (VE.9bit) product.
