CONFIGURATION
Although the SPR will operate without any configuration, HAI recommends that you use the UPB™ UPStart configuration software
to add the SPR to the UPB network with a Unit ID. Once added to the network, UPStart can then be used to adjust the receive
sensitivity of the SPR and perform communication tests between other devices to insure proper system signal strength.
Adding the SPR to the UPStart Network
The SPR is added in to a network just like most other UPB™ devices. Select Device Add Device, place the SPR into Setup Mode,
and then click the Next button. To place the SPR into Setup Mode, press the Program Button 5 times. To exit Setup Mode, press the
Program Button twice. While in Setup Mode, the Status LED will blink blue. Once the SPR is added to the network, it may be
assigned a Room and Device Name that is used 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 with the SPR and how well the SPR communicates
with all devices. The Repeater Communication Test will show a record of the signal strength, noise level, and phase at all devices.
Adjusting the Receive Sensitivity
If powerline noise is severe it may sometimes cause UPB™ communication to become unreliable. The SPR has 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.
Additionally, the SPR has a manual programmable (push-button) method to adjust its receive sensitivity. Press and hold the Program
Button for 5 seconds and then release it. The Status LED 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. When
the Program Button is released, the Status LED 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.
OTHER THINGS YOU SHOULD KNOW
Multi-Packets
The Split-Phase Repeater is designed to automatically repeat all multi-packet messaging transmissions which it receives in order to
enable UPB™ communication on a network. A multi-packet message transmits the same basic information more than once
back-to-back. All HLC 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 uni-packet (Gen 1) transmissions, then the SPR will not repeat them.
UPStart and the SPR
UPStart normally uses uni-packet transmissions to communicate to UPB™ devices however, once the SPR 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 (Same or Opposite) the PIM is
plugged into.
UPStart has a Network Discovery function that can quickly discover which Unit IDs are in use. In a very large electrical environment,
UPStart must use the SPR to gain access to this information on all phases.
Status LED Indications
The SPR has a blue/red status LED. When the SPR 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 Split-Phase Repeaters
If you install more than one SPR on a single electrical system, you should change the multi-packet messaging transmissions to three.
