Wiring Recommendations
We recommend using a AWG16 gauge and 12-24 VDC power supply when PoE supply is not used. The
voltage specified is the one measured on the product block connector: 12V-24 VDC (-15% / +10%).
The voltage drop due to the cable shall be considered. Table 3 shows the maximum distance between
power supply and one unique device, depending on cable gauge and power supply rating.

Power on Ethernet
Power supply to the terminal can also be provided by Ethernet using RJ45 connection (Power over
Ethernet - IEEE802.3af compliant). TBS recommends using an ethernet cable of Cat5e standard or
higher.
The terminal may be powered via a UL294 compliant PoE power injector or switch. According to the
PoE standard two modes are available: power on data pins and power on dedicated pins.
Use one or both types of power supply depending on PoE implementation in your local Ethernet
network. Both direct power supply and PoE can be connected at the same time.
NOTE:
If several terminals are powered through the same PoE switch, make sure the switch can provide
enough power to each device (minimum 11 W per 3D AIR and minimum 7 Watt per 2D IRON).

Ethernet Connection
For Ethernet connections, the wire terminal board provides a RJ45 LAN connector compliant with
IEEE802.3at.
For connecting peripheral devices, the used cable should be of Cat5 or higher, and does not need to
be crossed.
