Housecode setting for DS7000 with CM15A

[Geewiz]

With a CM15A already in place, when adding the DS7000, should the Housecodes be the same, or can they be different?

Does it matter?

Thank you!

For reliability, is does matter. Set the DS7000's house code to one that is not used and not transceived by the CM15A.

If you have 2 or more devices transceiving the same house code, then signal collision will occur.
