2. FUNCTIONAL DESCRIPTION
CSM800FH FCC ID: LW9-CSM800FH
Canada ID: 2119B-CSM800FH
Operates as a Frequency Hopping Spread Spectrum radio within the 902 to 928 MHz band. A guard
band of 175 kHz is applied at each side of the band to limit out-of-band emissions. The first possible
operating channel is centered at 902.175 MHz. Due to rounding, the last used operating channel is
927.7224 MHz.
Due to the large available operating bandwidth, the band is divided into 250 equally spaced operating
channels, with a 102.6 kHz channel spacing. Of the 250 operating channels, 5 groups of 50 equally
spaced, non-overlapping, channels are utilized under normal operation. Channel spacing within a
group is 513 kHz. The channel group (0-4) is determined by a configurable Network ID which must
be transmitted to the CSM800FH via serial interface before normal operation can begin. The channel
group is given by the equation:
ℎ = % 5
The dwell time for each of the 50 operating channels is 20 milliseconds within a 1 second period.
Each of the 50 channels is occupied only once during each 1 second period.
The hopping sequence (channel index order) is determined by a pseudo-random algorithm which
takes the Network ID as input and which guarantees each channel is used only once within the
sequence of 50 channels. When all 50 channels have been used, the hopping sequence repeats. Each
non-overlapping channel group utilizes the same hopping sequences, thus the number of unique
hopping sequences is 250 / 5 = 50. The hop sequence number (0-49) is given by the following
equation.
 =
5
Note that with a possible Network ID value of 255, 2 additional Hop Sequence indexes can be
obtained (50 and 51), but these yield the same channel sequence as Hop Sequence 0 and 1.

3. FCC COMPLIANCE NOTIFICATIONS
FCC Part 15 Notice
“This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.”
ISED RSS-Gen Notice
“This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the following two
conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired operation of the
device.”
“Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils
radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes :
1) l’appareil ne doit pas produire de brouillage;
2) l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en
compromettre le fonctionnement.”
For Canadian User
CAN ICES-3 (B)/NMB-3(B)”
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
“Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment”
WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible
label on the outside of the OEM enclosure specifying the appropriate Hetronic FCC identifier for
this product below.
“Contains FCC ID: LW9-CSM800FH”
“Contains IC: 2119B-CSM800FH”

RF Exposure
The Hetronic CSM800FH equipment has been approved for mobile applications where the equipment should be used
at distances greater than 20cm from the human body. Operation at distances of less than 20cm is prohibited and
requires additional SAR evaluation.
L'équipement Hetronic CSM800FH a été approuvé pour les applications mobiles où l'équipement doit être
utilisé à des distances supérieures à 20 cm du corps humain. Le fonctionnement à des distances inférieures à
20 cm est interdit et nécessite une évaluation SAR supplémentaire.
NOTE: FCC/IC warnings are to be incorporated into the manuals as provided to the end user.

8. Microcontroller Interface
Pin Layout
CSM FH uses a pin layout compatible with legacy Hetronic radio modules. This layout allows the
CSM FH to be used in devices that accept direct installation of the legacy module. Please note,
however, that the pins are not utilized the same way as the legacy radios, and software modification
of devices is required to make use of the CSM FH radio module.
