General Information
Terms of Use
Warnings and Cautionary Statements
Compliance
Terms of Use
Due to the nature of wireless communications, transmission and reception of data is not guaranteed. Data
may be delayed, corrupted (i.e., have errors), or totally lost. Although significant delays or losses of data
are rare when wireless devices such as the TGX™ Gateway are used in a normal manner with a well-
constructed communication network, the user should not rely on the TGX Gateway during situations where
failure to transmit or receive data could result in damage of any kind to the user or any other party,
including but not limited to personal injury, death, or loss of property. Industrial Scientific accepts no
responsibility for damages of any kind resulting from delays or errors in data transmitted or received using
the TGX Gateway or for failure of the TGX Gateway to transmit or receive such data.
Warnings and Cautionary Statements
Table 1.1 Warnings and cautionary statements
Read and understand this Product Manual completely before installing or operating the TGX
Gateway.
If you believe the TGX is not operating correctly, remove it from service and contact Industrial
Scientific.
Do not operate the TGX in areas where blasting is in progress or where explosive atmospheres
may be present.
Do not operate in classified hazardous areas, near medical equipment, near life support
equipment, or near any equipment susceptible to radio interference. The TGX transmits signals
that could interfere with this equipment.
For compliance with the Federal Communications Commission (FCC), only a trained and qualified
installer must complete the installation.
Install, operate, and service this equipment in accordance with your company’s safety policy and
any local Occupational Health and Safety Standards.

2
Table 1.1 Warnings and cautionary statements
The TGX Gateway is equipped with various radios that transmit signals. When the power cable is
connected, the TGX may transmit signals. Before connecting the power cable, be sure each
antenna is connected to its respective SMA input on the back of the TGX. Powering the TGX
without these antennas connected could result in damage to the internal transmitting devices,
causing reduced range, communication failures, or both.
The antenna cables carry high frequency signals; handle, install, and operate to prevent injury
and damage to the cable.
For compliance with FCC radio-frequency exposure limits, ensure a minimum distance of 20 cm
(7.87 ″) from each antenna to all persons.
Ensure a minimum distance of 61 cm (24 ″) between the antennas to help prevent Radio
Frequency Interference (RFI) during transmission.
The TGX Gateway antenna modules and their neodymium magnets can cause injury. To avoid
injury, Industrial Scientific recommends the following.
•Persons with a pacemaker or implantable cardio defibrillator (ICD) should maintain a
minimum separation distance of 90 cm (36 ″) between the pacemaker or ICD and the magnet.
Consult your physician or pacemaker or ICD manufacturer for additional guidance and
recommendations.
•Neodymium magnets have a strong attractive force. Each can attract quickly when in close
proximity to another magnet or a metal surface, and cause injury. The magnet material is
brittle; it can crack or splinter on impact to cause injury and potentially become a flying
hazard. Use protective gloves and eyewear to avoid a potentially severe pinch injury, cut, or
splinter.
•Keep magnets away from electronic devices, identification cards, credit cards, and other
items that use microchips, magnets, or magnetic fields.
Connect only compatible antennas specified by Industrial Scientific.
WARNING: Substitution of components may cause an unsafe condition.
The TGX exterior case, internal components, and antennas from Industrial Scientific are not
customer serviceable.
•Do not open the TGX or its antenna enclosures or alter them in any way.
•Do not use extensions with the antenna cables.
•Do not alter the power cable in any way other than to trim the unterminated ends of its wires;
do so only when the power cable input and its wires are not connected.
Do not use the TGX service input, which is for Industrial Scientific use only.
The antenna and power cables must be routed such that they will not be kinked, crushed, or
subjected to repeated bending (e.g., by a vehicle door).

3
Table 1.1 Warnings and cautionary statements
Ensure each antenna cable is connected to its one-and-only dedicated input. The cables are not
interchangeable.
The TGX requires fused connections to the vehicle battery and the ignition system; direct
connections are not supported.
Ensure each power-cable wire is connected to its one-and-only intended termination point and
ensure each connection’s integrity to avoid fire, damage to the vehicle’s ignition system, or
another unsafe condition or undesired result.
Do not interact with the TGX while driving. In many states and provinces, interacting with such
communications devices while in control of a vehicle constitutes distracted driving and is a
punishable offense.

Connected Safety
The TGX™ Gateway enables communication between Industrial Scientific gas-detection instruments and
iNet® Control software. Equipped with LENS™ (Linked Equipment Network for Safety), cellular, and
satellite capabilities, TGX provides the wireless connections needed for the transmission of gas readings,
alarms, GPS coordinates, and other data to iNet Control. This supports cloud-based iNet Now live
monitoring, allowing remote visibility to in-field conditions and potentially hazardous events. Connected
safety from Industrial Scientific is depicted below and supports the following:
•The safety team's preparedness for hazardous and unforeseen events.
•Cooperation among first responders within your company and from local authorities.

Key Features
The TGX is designed for the “mobile worker”, someone who may travel to one or more sites, including
locations outside a company’s in-fence facilities. This in-vehicle mounted gateway with its rooftop antennas
permits remote, live monitoring of its in-range, LENS connected gas-detection instruments.
Location restriction
IMPORTANT: Operate the TGX Gateway only in nonhazardous locations. LENS wireless permits the
wireless connection of a gas-detection instrument that is in a hazardous location to reach the TGX in its
nonhazardous, in-range location.
Instrument compatibility
Use the information supplied below to ensure gas-detection instruments are compatible with the TGX
Gateway. As needed, upgrade instrument firmware to the required version, add LENS Wireless
functionality, and refer to the instrument's product manual.

Communications
TGX Gateway uses LENS Wireless to communicate with gas-detection instruments. It uses cellular and
satellite (if equipped) to transmit those communications to iNet® Control for iNet Now live-monitoring.
Wireless communications are further described below.
Instrument–TGX Gateway
LENS Wireless enables communication among wirelessly connected instruments and gateway units
operating within a LENS group (e.g., Group A). The following also apply.
•Ten named LENS groups (A –J) are available.
•Each LENS group can host up to 25 equipment items.
•More than one gateway can be included in a LENS group.
Instrument communications exchanged through LENS are automatically encrypted with the Industrial
Scientific key. Optionally, a customer-supplied encryption key can instead be used.
TGX Gateway–iNet Control
TGX Gateway transmits communications it receives from gas-detection instruments to iNet Control using
cellular or satellite (if equipped). A Cellular and Satellite Unit will first use cellular and if that is not available,
satellite.
During operation, when the cellular or satellite network connection is lost or cannot be established and
messages cannot be sent to iNet, TGX will temporarily store the instrument data it receives and will retry

7
transmission upon network connection. Stored data are purged after transmission to iNet Control or when
the data have aged more than 12 hours, whichever comes first; data are purged every 30 minutes.
TGX Gateway cellular communications are secured through HTTPS. Satellite communications are byte
encoded.
TGX operation and vehicle power
To allow TGX operation to continue after the vehicle ignition is turned off and to maintain the desired
minimum battery voltage for the vehicle, use the features described below. These customer-settable
options are accessed through an internet connection to the TGX Configuration Manager (TCM), which is
discussed in Settings.
Keep awake
Enable the keep-awake feature to permit the TGX to continue operation after the vehicle is turned off. Set
the amount of time the unit will operate (keep awake) between engine shutdown and TGX power off. The
critical low voltage feature, discussed below, overrides the keep-awake feature.
Critical low voltage
Use the critical low voltage feature and your knowledge of the vehicle’s power system to set the battery
voltage at which the TGX will power itself off. Battery voltage requirements vary by vehicle and can be
affected by operating conditions, battery condition, and other factors. The critical low voltage value should
reflect the customer-determined minimum voltage that will achieve the following:
•Prohibit a running engine from the full loss of its battery power.
•Prohibit a nonrunning engine from completing an ignition cycle.
Notes:
10 VDC is the minimum voltage required for TGX start-up.
If the vehicle’s battery becomes depleted below the critical low voltage threshold, to restore power to the TGX, you may need to
disconnect, then reconnect the power cable to the unit.
Antenna and Power Cable Requirements
TGX wireless communications require the installation of compatible external antennas only from Industrial
Scientific. As indicated below, both the TGX Primary Antenna and TGX Satellite Antenna are required.

Vehicle Requirements
To determine if a vehicle is compatible, note the TGX Gateway power input requirements in the
specification table (below). The power-cable wires are connected to the vehicle as discussed in the section,
“Connections”.
TGX operation requires placement of a unit’s antennas on the vehicle rooftop. The magnet-mount antennas
support connection to a metal rooftop. For any nonmetallic rooftop surface, consult with the installer for
options that will provide a solid, rigid connection comparable to the pull force of the antenna’s magnet (see
Specifications below).
