network where messages initiated
from one device “hop” from radio to
radio in other nearby devices until
they reach the intended target device.
• If not many D1-528’s are installed yet,
this could prevent the messages from
the copy to D1-528 from reliably
reaching the copy from D1-528 and
continuing the room copy. You may
need to wait until additional D1-528’s
are installed so that a better mesh
network exists.
• Is there an RF interference source
between the copy from and copy to
D1-528’s? Like possibly a WiFi access
point or other radio transmitter.
• Is either D1-528 mounted on or near
a metal object that could be shielding
the RF signals from the D1-528’s? IF
these is, is it possible to move/remove
it or place the D1-528 at another
