Repeat the process for the receiver antenna – again using longer M3 screws to more
securely affix the antenna to the bracket. Note that the
receiver antenna enclosure does not have a vented back
side. When mounting this antenna, be sure that the side of
the enclosure with the embossed WiBotic logo is facing the
transmitter antenna.
To move the antennas relative to one another, simply loosen
the thumb screws and slide both antennas within the T-Base
channels. Now loosen the thumb screws and insert the head
of each thumb screw bolt into the slots on the T-base.
Please do not remove the antennas from their 3D printed
enclosures without consulting with WiBotic. High voltage on
the antenna coil PCBs can cause burns if touched during
power transmission. However, if removing the PCB
antennas is required, be sure to mount them with the coil
sides facing inward toward each other. The side of the coils
with the exposed capacitors is the back side, and the back
sides of both coils should be facing outward.
Once the antenna stand is set up, proceed with installing the antenna cables.
Connecting the Components
1. Connect one coaxial SMA cable between the Power Transmitter and the
Transmit Coil.
a. For TR-110 systems, make sure the connection is tightened to 8 inch-lbs.
on both ends.
b. For TR-300 based systems, hand tighten the larger type “N” connector on
the transmitter itself, and tighten the SMA connector on the transmit
antenna end to 8 inch-lbs.
2. Connect the second coaxial SMA cable between the Onboard Charger and the
Receive Coil. Make sure the connection is tightened to 8 inch-lbs on both ends.
3. Connect the Onboard Charger to the target device to be powered (e.g. the
battery) using the supplied battery connector cable. NOTE: The development kit
requires a direct connection to the battery for operation. The “heartbeat
mode” algorithm is disabled if the Onboard Charger does not receive
power from the battery before wireless power is enabled.
CAUTION: If using a battery power cable other than the one
supplied by WiBotic, be sure to follow the pin-out instructions in
the following section.
