Ztar Embedded RF TRANSCEIVER Instructions
Your instrument may be equipped with either a Standalone Receiver or a RF-MIDI USB dongle
receiver.
Power:
The Ztar Embedded Transmitter is connected to the power supply inside the instrument and it is always
powered-up with the Ztar.
The AirPower receiver may be powered either of three ways:
1) (2) AA batteries
2) 9VDC wall adapter
3) USB
The Receiver’s 3-way power switch settings are USB/Batteries<>OFF<>DC Power
MIDI Port:
On the transmitter the MIDI data that feeds its MIDI Input Port is wired internally directly to the Ztar’s MIDI
Output.
On the Receiver the MIDI port is connected to the MIDI Input of your synth or MIDI system.
Also, you can connect the AirPower receiver via USB to your host computer which will both power the
receiver and send USB-MIDI data into the computer.
Receiver Indicator Lamps:
Power: Power will blink if the battery is low
MIDI: The lamp will blink when MIDI information is being transmitted.
Link: The lamp shows when the transmitter and receiver are connected and will blink when the link is
experiencing a fringe reception condition.
Channel select:
The Transmitter and receiver are equipped with 16-position rotary switches to select a vacant RF
channel, 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. The Transmitter embedded in the Ztar has its channel selection
set at the factory to 0 in most cases.
When selecting a different channel, set the Transmitter and set the receiver to match. Power-cycle both
the transmitter and receiver to re-initialize the channel settings n both units.
When the transmitter is embedded in the Ztar, you can set the RF channel in the Ztar menu system. Go to
UTILITIES/MORE/WIRELESS. Set the RF channel to match the Receiver switch setting and set
Wireless=ON. When the channels match the LINK LED will illuminate.
9.6V Main Battery Supply (MIDI Battery)
[Newer Ztars are wirelessly powered over the USB port using a USB Power bank rather than the battery
wired to the MIDI plug.]
In order to be completely free of cables, when the Ztar is using the AirPower wireless data connection,
you can supply main power to the Ztar system by means of the special Starr Labs MIDI Battery. Simply
plug the battery into the Ztar’s MIDI Output port and it will supply phantom power through its MIDI cable
connection.
