ITR-01 Juno Tower System Integration Guidelines
Today’s modern classroom has a host of electronic devices used to support the instructional environment. Many of
these devices are connected together via a personal computer that typically acts as the control point for these devices.
Projectors, interactive white boards, document cameras, paging interfaces, etc, are all typically connected to a classroom
PC. In addition to these major devices there are often other support devices used to make these connections.
Your new Juno Tower is another electronic device that can also be connected to your classroom PC. But unlike the other
electronic devices mentioned above, the Juno Tower contains a sensitive Infrared radio receiver. To ensure that the Juno
Tower is providing good performance, it is important to follow good installation practices. When the Juno Tower is
connected to the classroom PC, it is now sharing a common ground reference with all the other devices connected to
the PC. If one or more of the devices has a poor or noisy ground reference, its poor performance can influence other
devices connected to the same reference and this includes your Juno Tower. To help ensure the best performance
possible, please refer to the installation guidelines listed below:
1. Connect the Juno Tower’s external power supply to a good AC mains point. Do not use extension cords and if a
power strip is used, ensure that it is of good quality.
2. Do not position the Juno Tower where sunlight can directly shine on the Tower. The Tower uses infrared signals to
link the transmitter to the receiver. Sunlight contains infrared energy and will reduce the system’s performance.
3. Use good quality audio cables when connecting the Tower to the classroom PC. Also use the appropriate length cable.
4. The USB cable provided with your Juno System has been qualified by FrontRow and should be used to connect the
Tower to the computer. If another length of cable is needed, then it must be certified for USB 2.0 or better.
5. Connect the USB cable directly to the computer. Do not connect via an External USB Hub device. Many
inexpensive hubs do not use quality components or good grounding principles.
6. Avoid running the USB and audio cables connecting your Juno Tower to the computer with other cables. Noise can
be present on the other cables and can couple into the cables connecting the Juno Tower to the computer.
