REGULATORY INFORMATION
7.1
FCC (United States) Certification
TCM 330U LIMITED MODULAR APPROVAL
This is an RF module approved for Limited Modular use operating as an intentional trans-
mitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The
module is optimized to operate using small amounts of energy, and may be powered by a
battery.
The module transmits short radio packets comprised of control signals, (in some cases the
control signal may be accompanied with data) such as those used with alarm systems, door
openers, remote switches, and the like. The module does not support continuous streaming
of voice, video, or any other forms of streaming data; it sends only short packets contain-
ing control signals and possibly data. The module is designed to comply with, has been
tested according to 15.231(a-c), and has been found to comply with each requirement.
Thus, a finished device containing the TCM 330U radio module can be operated in the Unit-
ed States without additional Part 15 FCC approval (approval(s) for unintentional radiators
may be required for the OEM’s finished product), under EnOcean’s FCC ID number.
This greatly simplifies and shortens the design cycle and development costs for OEM inte-
grators. The module can be triggered manually or automatically, which cases are described
below.
Manual Activation
The radio module can be configured to transmit a short packetized control signal if trig-
gered manually. The module can be triggered, by pressing a switch, for example. The
packet contains one (or more) control signals that is(are) intended to control something at
the receiving end. The packet may also contain data. Depending on how much energy is
available from the energy source, subsequent manual triggers can initiate the transmission
of additional control signals. This may be necessary if prior packet(s) was(were) lost to fad-
ing or interference.
Subsequent triggers can also be initiated as a precaution if any doubt exists that the first
packet didn’t arrive at the receiver. Each packet that is transmitted, regardless of whether
it was the first one or a subsequent one, will only be transmitted if enough energy is avail-
able from the energy source.
Automatic Activation
The radio module also can be configured to transmit a short packetized control signal
if triggered automatically, by a relevant change of its inputs or in response to receiving a
signal from another transmitter, for example.
Again, the packet contains a control signal that is intended to control something at the re-
ceiving end and may also contain data. As above, it is possible for the packet to get lost
and never reach the receiver. However, if enough energy is available from the energy
source, and the module has been configured to do so, then another packet or packets con-
taining the control signal may be transmitted at a later time.
