XB-24B connection

I have 2 Pro’s that I have connected with out a problem, but for the life of me these XB24’s have me stumped.

Unit 1 set for:

ZNET 2.5 Coordinator AT

Pan id :999

DH and DL set for the AH/AL of the second unit

Unit 2 set for:

ZNET 2.5 Router/end device ZT

Pan id:999

DH and DL set for the AH/AL of the first unit

The software does work with the Pro modules. On the TX side, I can see the LED flash as data is written, but the RX never sees data.

I cannot get them to talk to each other. Any thing I’ve missed?

Thanks!

These will be scrapped soon as too expencive in set up.

Come on guys. Any help?
