PRODUCT DESCRIPTION
The Powercast TX91501 Powercaster
transmitter is specially designed to provide
both power and data to end devices
containing the Powercast P2110 or P1110
Powerharvester receivers. The TX91501 is
housed in a durable plastic case with several
mounting options. Operational power is
provided to either of the two DC power
connectors at 5V DC. The TX91501 includes
a status LED to provide feedback on
functional state. The TX91501 has a factory
set, fixed power output and no user-
adjustable settings. The label indicates the
effective power for which the device is
configured, with 3 watts EIRP being the
maximum. Once properly mounted,

SET-UP AND OPERATION
1. Wall-mount the TX91501 in the desired location with the Powercast logo and status LED
facing the direction in which the energy is desired. For permanent installations, mount
the TX91501 eight feet or more above floor level.
2. Plug the DC connector of the power supply into one of the two available connectors on
the TX91501. Plug the power supply into a 120V outlet.
3. When the green LED illuminates, the TX91501 is active and transmitting radio frequency
(RF) energy. Data is automatically included in the transmission and can be received by
one of Powercasts Powerharvester Modules.
The status LED indicates the following operating conditions:
LED Status Description
Off Off 5VDC is not applied
Green Active Transmitting normally

If operating on a flat surface for testing purposes, such as a table, it is recommended that the TX91501 is elevated off the surface with a non-
conducting material, such as foam or a cardboard box, OR the TX91501 is positioned near the edge for unobstructed transmission.
