Front View of EtherWave-WMR

The EtherWave-WMR is a fully-enclosed unit ready to be interfaced
to external devices.

Any EtherWave-WMR may be configured as a Master, Repeater (or
Repeater/Slave), or Slave. This versatility is very convenient from a
’sparing’ perspective, as well for convenience in becoming very
familiar and proficient with using the device: if you are familiar with
one unit, you will be familiar with all units.
