RF Hardware Installation
Hand Held Tranceiver - 3 (HHTR-3)
The DCSI Hand Held Transceiver - (HHTR-3) is used to configure and setup the
EMTR-3 (installed in the electric meter). The HHTR-3 is used to establish the
communication link between the EMTR-3 and the ORION
®
transmitter and can be
used to test the radio link.
RF Hardware Installation
This section provides instructions for installing the RF hardware on-site. A
functioning network can be created and its functionality verified before leaving the
site.
Pre-Installation Field Survey
The field survey is used to review the environmental conditions present at any
particular location and lay out the system to maximize performance. DCSI
recommends that you conduct a field survey before performing the actual hardware
installation.
As with all RF devices, certain environmental conditions must be present to
optimize RF communications. Be aware of the factors that affect the radio
transmission between the ORION and the EMTR-3 when performing the field
survey, such as:
• Metal objects
• Thick walls or foliage
• Local radio interference
• Position of the ORION and/or EMTR-3
Factor in all environmental conditions when planning the location of the
meter/EMTR-3 assembly.
N OTE A clear line of sight between the ORION transmitter and receiver is preferred,
but is not always attainable.
The following section discusses the environmental conditions that may affect RF
transmissions between the ORION and EMTR-3.
