PS2 TIU Questions

Apologize if this has been covered already.

Recently acquired what appears to be an original TIU. No “rev” on the bottom and has “ProtoSound 2” logo instead of “DCS”. I confirmed it will power up. I understand the older versions had signal strength issues but my layout is not large.

I purchased the DCS Companion 3rd Edition but haven’t finished yet.

Can my old TIU be upgraded to current DCS software? A dealer told me only “rev l” and higher can be, but I saw here that any TIU can be upgraded.

Can I use WiFi as primary control (with serial cable) and not purchase a remote?

Can I run a TMCC Command Bass AND WIU at the same time using a “Y” serial cable?
