Operation and Installation Manual

Product Review

The next century GW-301 (Cellular Gateway) is a powerful communication device for collecting and syncing meter usage and status data to the NextCentury Cloud. An embedded cellular modem provides an instant data connection right out of the box, making setup fast and easy*. The Gateway user interface can be directly accessed via a simple connection to a compatible Android or iOS device using the NCSS mobile app. The GW-301 includes easy-to-understand LED indicators, providing instant device status. The GW-301 Gateway includes an integrated NextCentury radio for connection to NextCentury Transceivers and Repeaters.
*Monthly data plan is provided by next century. You can easily enable/disable cellular service remotely from the NextCentury web portal. Data is affordably provided with no contracts or hidden fees.

Installation and Mounting

Mount the Gateway

Each Gateway comes with a mounting plate and can be installed using the mounting screws and anchors to secure the Mounting Plate to the wall.
Note: To maintain stability, a minimum of two screws and anchors must be used on the mounting plate (Figure 2-A). The gateway should be secured to the wall using the provided mounting screws and anchors, and should not be mounted with 3M Tape alone.

 Mount External Cellular Antenna
  • Attach the magnetic base of the cellular antenna to the wall.
Power the Gateway
  • Plug Power Supply into the 15-volt power port (Figure1-A).

Direct Connect

Connect with Gateway Using Mobile App

When the internet connection is provided to the Gateway requires set parameters (WiFi, network static IP, etc.) then a direct connection can be established with the Gateway using an Android or iOS device and the NCSS mobile app.

  1. Your mobile device’s Bluetooth must be turned on and within 10 feet proximity to the Gateway.
  2. Open the NCSS mobile app and select “Direct Connect” from the menu.
  3. Tap the Gateway device as it appears (fig. 3).
  4. Tap the Settings icon and adjust the connection parameters as needed.

Data Connection Options

Determine your preferred internet connection type to establish NextCentury Cloud connectivity.

Option 1: Integrated Cellular
1. Enable cellular data plan for the Gateway by navigating to the property settings using the NCSS mobile app or by navigating to the NextCentury web portal on your browser.
Note: The data plan is available on a month-to-month basis and can be canceled at any time. Cellular can also be turned on remotely at any time through the web portal.

Option 2: Internet

  1. Plug Ethernet cable into the Ethernet port (Figure 1-B).
  2. If the property network requires a static IP, or other configuration parameters, then use the “Direct Connect” feature available from the NCSS mobile app (section 4).

Note: The Gateway does not need a static IP address unless required by the network configuration. It can be placed on either a WAN or LAN network and use a DHCP address.

Option 3: WiFi

  1. Using the “Direct Connect” feature on the NCSS mobile app to select a nearby GW-301 (section 4).
  2. Tap on the “Settings” icon to access network settings.
  3. Tap “Find Network” under the WiFi section and then select from the available WiFi networks. A password can then be entered.

Note: On unrestricted networks, the Gateway will automatically connect to the next century Cloud. If the Gateway does not connect, please be sure that the network does not require proxy login information and that TCP traffic is not blocked. If a proxy login or firewall is present on the network, a whitelist policy will need to be created by the IT manager for the property.

Power Indicator
  • When the Gateway is plugged in, the Power Indicator LED (Table 1) will be solid green indicating the device is powered on but not connected with the NextCentury Cloud. A solid blue Power Indicator LED signifies the device is powered on and has connected with the NextCentury Cloud. The Power Indicator will turn red if a loss of power occurs. If the Gateway is being reset, the Power Indicator LED will blink red one time.
Setup Indicator
  • When the Gateway has been programmed to a property, the Setup LED indicator (Table 1) is solid green. If the LED is blinking green then the Gateway is programmed to a property AND the Mobile App is directly connected to the Gateway. If the LED is not on after the device has powered on, then the unit has not yet been programmed to a property. If the LED is blinking yellow then the Gateway has not been programmed to property but the Mobile App is directly connected to the gateway. or be able to sync with the NextCentury Cloud.
RF Activity Indicator
  • This LED will be off when the Gateway does not detect any real-time RF activity (if the Gateway is not sending or receiving messages from any repeater or transceiver onsite).
  • 3 rd Party Device Transmissions: The LED will briefly flash red when the Gateway is communicating (sending or receiving messages) with an unprogrammed 3 rd party device. The LED will briefly flash yellow when the Gateway is communicating with a programmed 3 rd party device.
  • Next Century (NCSS) Device Transmissions: The LED will briefly flash green when the Gateway is communicating (sending or receiving messages) with an unprogrammed NCSS device (RE-201 Repeater or TR-201 Transceiver). The LED will briefly flash blue when the Gateway is communicating with a programmed NCSS device.
3G/LTE Indicator
  • The 3G/LTE indicator will be red, yellow, or green depending on the available signal strength. Red is an
