UtiliNet SCADA Single Board Radio 98-1546 Rev AA 43
Regulatory Compliance
The endpoint module has been designed to meet the following standards:
• FCC - CFR Part 15.247 - Radio Frequency Devices, Subparts A-General and B-Unintentional
Radiators (testing is done at a module level for Modular Approval)
• Industry Canada
FCC - CFR Part 15.247
Both versions of this product are certified with Modular Approval under the same FCC ID number.
Modular Approval is used because the product may be used in a variety of customer assemblies and
configurations. Modular Approval avoids the need to qualify each individual end-product assembly.
However, the customer must adhere to certain rules in order to stay compliant.
For customers using the Internal Antenna version, an FCC ID sticker must be affixed to the outside
of the end-product assembly, stating this Modular SCADA/DA Utilinet board is contained within.
For customers using the External Antenna version, the end-product assembly must also have an FCC
ID sticker stating this Modular SCADA/DA Utilinet board is contained within. In addition, though,
special rules apply to the antenna:
• The antenna (and any associated RF cables connecting the antenna to the board) must be exactly
the same as the one used for certification OR the same type antenna and equal or less gain than
the antenna used for certification.
• The antenna (and associated RF cables) must have unique connectors, so that an end user cannot
connect a non-approved antenna.
The point is that the FCC does not want a customer to attach an antenna with more gain and thereby
possibly exceed the radiated output power and spurious limits. Landis+Gyr chose to use a 5 dB whip
antenna made by MMG (Manufacturer's Marketing Group) to qualify this product. More information
about this specific antenna is found in “External Antenna” on page 35.
This antenna was chosen due to its good performance, availability, relatively low cost, and
comprehensiveness (qualification with this antenna should cover most other antennas available on
the market that could potentially and realistically be used with this product).
If a customer wants to use a different antenna, they are welcome to do so. If the alternate antenna is
the same type (whip) and equal or less gain (5 dB), then it falls under Modular Approval and no
further action is required. However, if the antenna is a different type or more than 5 dB gain, the
customer must re-qualify the assembly for compliance.
The requirement for unique connectors is satisfied by using an MCX Female connector on the
Modular SCADA/DA Utilinet board and a Reverse-Polarity N-Type Male/Plug connector on the
5 dB whip antenna from MMG. MMG also makes the RF coaxial cable to connect this antenna to the
