Regulatory Compliance
7 Regulatory Compliance
7.1 Introduction
The purpose of this chapter is to describe which behaviour the user MUST have in order to
operate the device under compliance with current regulations. The details described here
are then to be read carefully and applied literally. Also, please read carefully all the other
documentation available in order to understand all the limits and ensure compliance of
the final application.
The module
EMB-Z2538PA
is certified for CE and FCC compliance. The different
regulations have different limitations and impose different approaches to the module that
will be discussed in different chapters. Any aspect that both the regulations have in
common will be described in an appropriate chapter in order to keep readability of this
document at maximum.
The main aspect that the user MUST consider is the output power. The module itself is
compliant and ready to be used but care must be taken in setting an appropriate output
power when programming the devices. The module can output up to 22 dBm of conducted
power which translates into up to 20 dBm of EIRP with the integrated antenna or more if
using an external antenna. Please follow the directives in this document to set the
appropriate output power for the antenna you are using. Any other antenna that is not
covered in the certification must not be used unless a new certification is performed.
7.2 Compliance: Important information
The module is to be used in accordance with the current guide. Any hardware
modification on the module will void the certification.
The use of the module is allowed only with the Embit's modified version of the Texas
Instruments software stacks (TIMAC, Z-STACK) on the standard IEEE 802.15.4
channelization (from channel 11 @ 2405 MHz to channel 25 @ 2475 MHz) The channel 26 is
not available due to FCC restrictions. Any modification of the software stack is prohibited.
The antennas used must be one of those indicated by the manufacturer and the output
power must be set as required by the present document.
The EMB-Z2538PA can operate using the internal PIFA antenna or with an external antenna
attached via the U.FL connector. For the specific FCC certification, the list of allowed
antenna are indicated in the following table. The use of any other antenna is permitted
only with a FCC Class two permissive Change.
There is no duty cycle limit for this module if the appropriate power settings are
respected.
The module can only be used with the antennas specified in the following table and the
power setting must not exceed those indicated in this table for each antenna and
operative area (CE or FCC). If the module is using the integrated antenna, please consider
the settings specified for the EMB-AN24-15PFA antenna.
