FCC Identifier: PWR-WCSNM941

Trimble SNM941-90 complies with FCC radiation exposure limits set
forth for an occupational/controlled environment. This equipment
should be operated with a minimum distance of 20cm between the
radiator and your body or another transmitting antenna.

The marketed product name is SNM941.

The -90 variant of the SNM941 is certified for use with the Trimble
GNSS, 112057.

In order to maintain compliance with FCC RF exposure requirements,

the Trimble SNM941 antenna, 112057 must be used.

Class A Statement – Notice to Users

This equipment has been tested and found to comply with the limits for
a Class A 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 communication. 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 or
more of the following measures:

are trademarks

– Reorient or relocate the receiving antenna.

– Increase the separation between the equipment and the 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 and modifications not expressly approved by the
manufacturer or registrant of this equipment can void your authority to
operate this equipment under Federal Communications Commission
rules.

Safety Information

Before you use the Trimble® SNM941 Connected Site® Gateway, ensure that you have read and
understood all safety requirements.

WARNING – This alert warns of a potential hazard which, if not avoided, could result in severe

C

injury or even death.

CAUTION – This alert warns of a potential hazard or unsafe practice that could result in minor

C

injury or property damage or irretrievable data loss.

NOTE – An absence of specific alerts does not mean that there are no safety risks involved.

CAUTION – The operating temperature range is –30° C to +85° C and the storage temperature

C

range is –40° C to +85° C. Exceeding these ranges may cause damage to the unit, machine, and
the operator.

Installing antennas

CAUTION – If wiring around the negative master disconnect, the antenna mount must be

C

electrically isolated from the asset’s chassis ground.

CAUTION – For your own safety, and to comply with the RF Exposure requirements of the FCC,

C

always observe these precautions:
– Do not locate antenna within 20 cm of any other transmitting antenna, to avoid co-location
issues.

Wiring notices

CAUTION – Wiring around a master disconnect switch, if installed, may void the warranty of the

C

machine or equipment. Refer to the machine or device user manual and warranty information. If it
is deemed necessary to wire around this switch and directly to battery a 5 A fuse must be
installed on the Battery Negative line of the harness.

familiar with GNSS or vehicle telematics, visit the Trimble website (www.trimble.com) for an interactive
look at Trimble and these technologies.

About the SNM941 device

The Trimble® SNM941 device comes in two models. The SNM941-60 supports cellular communications
in all regions excluding the Americas (but including Brazil). The SNM941-90 supports cellular
communications in the Americas (excluding Brazil). Both variants offer GNSS positioning, cellular
communications, wireless LAN communications, Ignition sense, Engine On sense, three digital inputs,
one analog input, and wired communications using CANbus, RS-232, and Ethernet.

The Trimble SNM941 devices are designed to operate reliably in very harsh installation environments

Exterior description

The Trimble SNM941 device is a rugged telematics and data communications appliance. The device
enclosure is made of heavy duty aluminum. The front of the device contains the electrical harness
connector (see page 12) and antenna ports (see page 11). The bottom of the device includes the four
mounting through-holes (see page 12).

Electrical harness connector

The electrical harness connector is a 34-pin weatherproof electrical connector with a mechanical
locking system. For a description of the connector signals and wiring harness configuration, see

Chapter 6, SNM941 Wiring Harness.

Some machine installations may use a specialized wiring harness depending on the telematics features
a

ailable on that particular machine. Trimble recommends that you use only harnesses provided by

Trimble or by your machine’s original equipment manufacturer.

Antenna connectors

The SNM941 device has four connectors that connect to the 4-In-1 antenna, Trimble P/N 112057:

• GNSS antenna connector – This connector is a SMA jack.

• Two cellular modem connectors – One connector is a TNC jack and other is a reverse polarity SMA
(RP-

SMA) jack.

• Wireless Local Area Network (WLAN or Wi-Fi) antenna connector – This connector is a reverse

Mounting provisions

The SNM941 and antenna is intended to be mounted directly to the asset that is being monitored, with
the exception of the machine chassis. The bottom of the antenna has an industrial adhesive that can be
used to mount the antenna directly to the device/machine. The antenna can only be directly adhesive
mounted to non-metallic surfaces that do not have metal immediately underneath. If mounting to a
metallic surface, you need an antenna riser, P/N 112056. The riser can be mounted with fasteners,
adhesive, or magnets.

In cases where the adhesive will not adequately s
antenna to the riser P/N 112056 ahead the time in a warm environment. Then fix to the asset using
fasteners or magnets.

In the case of installations where extreme vibration may be encountered, such as directly on the chassis
o

a tracked machine, you should mount the SNM941 using a mechanical shock isolation system.
