FUNCTION
The TPR-120 Three-Phase Repeater is a small electronic
device that enables communication between
PulseWorx™ & other devices using the Universal
Powerline Bus (UPB™) method of communication on a
three-phase 120/208VAC delta-wye 60Hz powerline.
The main purpose of the TPR is to transfer UPB™ multipacket messages transmitted on one phase (leg) of the
electrical system and strongly repeating them on to the
other phases (legs) to ensure proper communication.

2. Install the repeater into a suitable workbox or
equivalent enclosure.
3. Run wires from a three-pole circuit breaker to the
workbox for Phase A, Phase B, Phase C, and Neutral
(see illustration below).
4. Use wire nuts to connect the TPR’s black wire to Phase
A, and the red wire to Phase B, and the blue wire to
Phase C. Connect the TPR’s white wire to Neutral.
Check that there are no bare wires protruding and
cover the wire nuts with insulating tape if necessary.
5. Check all wiring and connections, and turn on the main
breaker.
6. All three status LEDs will light up if all of the
connections are proper.
Why Do I Need a TPR-120?
UPB™ communication was designed to work on a single
phase powerline. However in a three-phase
environment the signals will not directly jump across all
three phases of a 120/208V electrical system. The TPR
was invented to take any UPB™ multi-packet generated
signal on a single phase and repeat them onto all three
phases of the powerline.
INSTALLATION
The TPR-120 works best when installed as close to the
main circuit breaker panel as possible.
Note: Installation must be carried out by a qualified electrician
only. The main breaker must be turned off during installation
and the repeater must be installed in a suitable junction box or
equivalent enclosure. Installation must be carried out in
accordance with all applicable codes and requirements,
including, but not limited to, the National Electrical Code
(NEC).
1. Turn off the power at the main breaker panel.
CONFIGURATION
Although the TPR-120 will operate without any
configuration, we highly recommend that you use the
UPStart Setup Software to add your TPR to the UPB network
with a Unit ID. Once added to the network UPStart can
then be used to adjust the TPR’s receive sensitivity and
perform communication tests between other devices to
insure proper system signal strength.

Installation Guide and
Three-Phase Repeater
Adding the TPR-120 to the UPStart Network
The TPR-120 is added in to a network just like most other
UPB™ devices. Select DeviceAdd Device, place the TPR
into Setup Mode, and click the Next button. The TPR’s
Program Button is tapped 5 times to enter the TPR into
Setup Mode and double-tapped to exit from Setup
Mode. While in Setup Mode the Status LEDs will blink
blue. Once the TPR is added to the network, it may be
assigned a Room and Device Name that are meaningful
for identification purposes.
Performing Communication Tests
It is important that the communication of your UPB™
network be tested to insure proper system signal
strength. UPStart has a Repeater Communication Test
that will test how well each device communicates to the
TPR and how well the TPR communicates to all devices.
The Repeater Communication Test will show a record of
the signal strength, noise level, and phase at all devices.
Owner’s Manual v2.2
Multi-Packets
The Three-Phase Repeater is designed to automatically
repeat all multi-packet messaging transmissions, which it
receives in order to enable UPB™ communication on an
entire three-phase network. A multi-packet transmits the
same basic information more than once back-to-back. All
PulseWorx™ devices (and most other UPB™ devices) are
pre-configured at the factory to use 2-time multi-packet
messaging. If any of your devices are configured to use unipacket transmissions then the TPR will not repeat them.
UPStart and the TPR
UPStart normally uses uni-packet transmissions to
communicate to UPB™ devices however, once the TPR is
added to the network, it will automatically switch to using
multi-packet transmissions. UPStart indicates that it has
switched to two-time multi-packets by displaying TX=2 in
the status bar. Next to this indication UPStart will also
display which phase (A, B, or C) the PIM is plugged into.
Adjusting the Receive Sensitivity
If powerline noise is severe it may sometimes cause
UPB™ communication to become unreliable. All
PulseWorx devices, including the TPR, have an adjustable
receive sensitivity which may be set to LOW or HIGH via
UPStart. The low setting will help block the noise from
affecting the reception.
The TPR additionally has a manual programmable (pushbutton) method to adjust its receive sensitivity. Press
and hold the Program Button for 5 seconds and then
release it. The Status LEDs will blink red to indicate the
current receive sensitivity setting – once for LOW or
twice for HIGH. To adjust the receive sensitivity to LOW
single-tap the Program Button. To adjust the receive
sensitivity to HIGH double-tap the Program Button.
Press and hold the Program Button for 5 seconds to set
the new receive sensitivity. Release the Program Button
and the Status LEDs will turn back to blue.
Once the Receive Sensitivity has been changed the
Repeater Communication Test should be repeated to
insure proper system signal strength and
communication.
UPStart has a Network Discovery function that can quickly
discover which Unit IDs are in use. In a three-phase
electrical environment UPStart must use the TPR to gain
access to this information for all three-phases.
Status LED Indications
The TPR has a blue/red status LED for each phase of the
powerline. When the TPR is transmitting on the powerline
it will turn the LED red. When it is receiving on the
powerline it will turn the LED purple. When nothing is
happening on the powerline the LED will stay blue.
Multiple TPR-120s
We do not recommend installing more than one ThreePhase Repeater on a single electrical system.
