GATEWAY NAME AND POWER SWITCH
Gateway Name:
The Gateway Name is labeled on the side of the
gateway with the handle. The gateway name is
EPAERTXXX where X represents a unique number.
Power Button:
Depending on the build of your Smart Gateway, the
power switch can be either a toggle switch or a push
button. The toggle switch is convenient in that it
allows the gateway to remain on when switching
between shore power and battery. However, it is easy
to accidentally turn the switch on/off when picking up
the gateway or when packing the gateway in a case. If
it is necessary to ship the Gateway, it is recommended
that a piece of tape be applied over the switch to keep
it in the off position during shipping.
Motherboard Reset Port:
There is a port covered by a screw that allows for a
hard-reset of the gateway motherboard. See the
troubleshooting section later in this manual for
additional details.

Section 1 – Using the External Ports on the Smart Gateway
The Smart Gateway has four (4) external ports for connecting instruments. There is one (1) port to
which a traditional gateway LINC cable can be attached (COMx), an Ethernet Port and two (2) USB
ports which can be configured to communicate with RS232 Serial connections. There is an
additional port for future expansion which could potentially be used for instruments that output
voltage, but the port is currently not functional. Refer to the ‘Smart Gateway Hardware Information’
section of this document for additional details.
The external LINC port on the Gateway will be assigned a COM port number that matches the
setting in Windows on the Laptop inside the Gateway. The LINC numbers that are added to Survey
Controller will represent the COM port to which the instrument is connected. It is recommended that
a standard naming convention be used for these custom LINC numbers. For cnsistency, keep the
name convention with the 1000 series and include the COM Port number for the connection. For
example, when connecting a cable to a port assigned COM5, a LINC will be added to the equipment
inventory in Survey Controller with a number of 1005. If connecting an instrument to a port assigned
COM6, the LINC number in Survey Controller would be 1006, and so on. The COM port should be
identified using Windows Device Manager for each instrument attached via USB prior to adding to
Survey Controller. NOTE – An SPM Flex will NOT be assigned a COM port number since it
connects to the Ethernet port on the Smart Gateway. See the SPM Flex section for additional
details.
Using COMx (Traditional LINC Cable Port)
When using the traditional LINC cable port on the Gateway (Gen 3
and above), note the COM port number labeled on the outside of the
Gateway. Substitute that number for the COMx reference in the
steps below.
1. Login to the Gateway’s internal laptop. Refer to the ‘Accessing the Smart Gateway’ table above
for login options.
2. Add a custom LINC number for COMs to Survey Controller. For illustrative purposes, COM5 will be
used.

Using the USB Ports to Connect Instruments – Serial to USB (i.e., DustTraks)
Section 5 of this guide outlines how to directly connect a RAE Host to the Smart Gateway USB
port and configure a run in Survey Controller.
When connecting an instrument using a Serial (RS-232) to USB connection, the Laptop inside the Smart
Gateway will assign a COM port number for that connection. If using both USB ports on the Gateway or if
using a USB splitter to add instruments, it is important to only connect one instrument at a time in order to
identify which COM port is assigned to which connection.
Hardware Note: Only certain Serial (RS-232) to USB connectors will work. If the
connector is not automatically assigning a COM port number, try another connector.
The connector should be FTDI compliance and use a Virtual Com Port Driver. The
driver that is already loaded on the laptop in the Gateway should be sufficient when used
with the proper connector.
1. Open Device Manager – BEFORE CONNECTING the
Serial to USB cable to the Gateway
 Click the Windows Search Icon in the lower left
corner of the screen
 Type ‘Device Manager’ in the search bar and
press enter
 Expand the ‘Ports (COM & LPT)’ section. The
COM Ports that are already assigned will show in
the list. Make note of which COM ports are
already assigned.
KEEP THIS WINDOW OPEN
2. Connect the instrument to the ‘Serial to USB Cable’ and
connect the USB end to one of the USB ports on the Smart Gateway.
 DustTrak Note: Since the DustTrak connection is USB and the Smart Gateway connection is
USB, a Female to Female DB9 Null Modem cable must be used between two Serial to USB
connectors.
 When the connection is made on the Smart Gateway
(USB cable is plugged in), Device Manager should
display the new COM port assigned for that
instrument connection. Make note of the new COM
Port.
3. From this point forward, the steps are the same as outlined in Section 1.
 Add a custom LINC number for COM7 (LINC 1007) to Survey Controller
 Start a Run in Survey Controller
 Unlock the MeterApp, Stop the MeterApp Run and configure it for COM7 and the
instrument-specific baud rate
 Start the MeterApp Run. Sensors should turn green and samples should increment…

Using the Ethernet (RJ45) Port (SPM Flex)
1. Verify that the Ethernet Port is configured as LAN
 Login to the Cradlepoint and navigate to Networking – VLAN Interfaces (Refer to the table
above for login information for the Cradlepoint modem)
 Look where port 0U is configured. If it is in the LAN section, the Ethernet Connector is set to
work for an instrument connected to the external Ethernet port (i.e., SPM Flex). If the 0U
port is missing or is in the WAN section, see the Internet Sources section below for details on
configuring the Ethernet port to have 0U in the LAN section.
2. From this point forward, the steps are the same as outlined in Section 1 EXCEPT, the instrument will
be using an IP Address instead of a COM port in the ‘Data Input Settings’ tab of the MeterApp and
the custom LINC number will be the last three digits of the Flex’s IP Address.
 Add a custom LINC number for the Ethernet Port to the Equipment Inventory in Survey
Controller. Use the last three digits of the SPM Flex IP address as the LINC number. For
Example, an SPM Flex with an IP address of 192.168.3.150 would have a LINC of 150
added to Survey Controller. An SPM Flex with an IP address of 192.168.3.142 would have a
LINC of 142 added to Survey Controller, etc.
 Start a Run in Survey Controller
 Unlock the MeterApp, Stop the MeterApp Run, and configure the ‘Data Input Settings’ tab
as shown
 Configure the MeterApp to use the IP Address
 In the LINC Setting section, verify the SPM
Flex’s IP Address in the ‘Meter’s IP Address’
box
 Enter port 502 for an SPM Flex
 Remove the checkmark from ChkBat-Sig
 Configure GPS as shown
 Click Save and Configure
 Start the MeterApp Run
 Click Run – Start
Sensors should turn green and samples should increment.
Close the MeterApp and let it re-launch if the sensors don’t turn green.
