Operating midiBeam
If TX02 and RX02 have been setup as described before in A) or B), turn them on
both. TX02 has a battery switch for that, RX02 has no switch, it is powered
through the USB cable either from the supply or from the computer. If the two
devices are not paired (“Pairing” means tuning them to a common radio
channel), then both of them will blink slowly, with a short blink. If you press
the button on either of them, it will change to fast blinking, which shows that it
is searching for a pair. Press the button on the other one as well, and they will
blink both together for a few seconds, then at once both of them change to
continuous light. This means that they are paired now, they allocated one of 76
radio channels for themselves in the 2.4 GHz range where midiBeam operates.
You can start to play your keyboard, and whatever you send into the MIDI IN
of TX02 (the DIN plug hanging on a short cable), will appear on the DIN and
USB outputs of RX02. Both devices will store their channel settings in
permanent memory, so when you turn them on next time they will remember
on each other. The range of safe functionality is very much depending on the
environment. In open air, LOS (“Line Of Sight”, no objects between TX02 and
RX02) more than 350 meters range can be measured, but reflections in rooms,
objects in between the devices and the momentary direction of the antennas
can influence it. Anyway, the range is more than enough under any conditions
on a huge stage in a hall or open air, or in a studio even between neighbouring
rooms; you will not have to drill holes in the wall for an ad hoc connection.
During the pairing process midiBeam will automatically avoid radio channels
with activity from other devices, also from other pairs of midiBeam. So, if you
want to use several pairs of them on the same location, then this is all what
you have to do:
1. Make sure that only one pair is turned on (also RX02 devices must be turned
off). Pair them.
2. Leave the previous pair running, and turn on the next pair. Pair them.
3. Continue from 2., until all pairs are tuned.
Remember, you have to do this only once. Once you set them up all, they will
all remember their settings.
As said before, during pairing midiBeam avoids any radio channels with
disturbances. If you find unusual difficulty with the transmission quality, then it
is worth to initiate a new pairing. Maybe a disturbing source has been turned
on close to the room (e.g. a Wi-Fi). Then midiBeam will adopt itself to a new
channel that is free.
