So, it looks to me like if you use Wi-Fi with two TIU's you need a Wi-Fi module for each, and that means that both need to be Rev L in order to hook up the Wi-Fi module to the TIU's.
Do I have this right or is there a way to have two TIU's work with one Wi-Fi modules?

A serial adapter works on older units. New TIUs "Version L"s don't. Same WiFi unit works on either. One per TIU.
The comment "Same WiFi to both" has me confused.
So to be sure I understand. . . I need a wifi module connected to each TIU? So for two TIUs I need 2 wifi modules?
One TIU is older and does not have a USB port. Can I use a usb to serial connector and get full wifi functional capability with this older TIU?
Thanks.
Yes 1 WIU per TIU and yes the older TIU will work with a USB to serial adapter just fine.
I tried to clean up the response above. Sorry.
Now that I re-read it, I thought your post described a version L WIFI unit. I believe you were just describing 2 TIUs and I got confused.

No problem. I really appreciate you taking the time to try to help.

Thanks! I think I understand now. Glad to hear I can use the older TIU as I didn't relish having to buy another.
Great forum.
I think that the TIU needs to be V 5.0 or later. So, you may need to update an older TIU. The DB9 USB to serial converter is cheap on eBay. I also purchased a "1FT DB9 Y Splitter Cable Video Adapter Male to 2x Female PC 9Pin D-Sub RS232 12"". This allowed me to connect my TIU to the WIU AND a TMCC Command base with MTH 50-1032 cable.
Theoretically, you just may be able to connect two TIUs and the WIU with a USB Hub. There is a 4 port version on eBay for $4. This would be worth trying before you buy two WIUs. If both TIUs are set to TIU #1, it ought to work. I know you can talk to two TIU #1s using one DCS Remote. You may get lucky and it just might work the same way with WIU. If it doesn't work, no harm, no foul. Toss the hub in your computer bag. FWIW just for grins, I just bought one. I'll be testing it on RC3R's TIUs and WIU in the near future.
I did just receive and test a "5.5x2.1mm 12V CCTV Camera 1 Female to 2 Male DC Power Splitter Cable Adapter". You can power the auxiliary ports for two TIUs with one Z500 brick.
