NMS044 Reference Manual Establishing Service for the Gateway 13
2.2 Establishing Service for the Gateway
Establishing cell service for the gateway includes purchasing a SIM card with cellular
service and installing it. As indicated in this section, you can also opt to have Larson Davis
install and activate the SIM when your system is prepared at the factory.
2.2.1 Purchasing Cellular Service
Review this section prior to purchasing cell service.
The NMS044 system requires a SIM card with a data plan. SIM cards should be configured
with a static IP address or alternatively with a dynamic IP address used in conjunction with
the optional SoundLink service, as described in this section. Where available at an
affordable price, we recommend using a SIM card configured with a static IP address.
Step 1. When shopping for a cellular provider, verify that the service supports a public,
static IP address, and that incoming connection requests are not blocked.
If this type of SIM card and service is available, move to the next step; if not, we
recommend the SoundLink online hosting service. This enables you to establish
a secure connection to your gateway(s) using any IP address on a virtual private
network (VPN). Contact Larson Davis or your representative for more
information about this subscription-based service.
Step 2. Purchase a SIM card with the following features:
• A data plan sufficient to the NMS044 data usage
The amount of data your system requires is variable. For most applications, 4
GB per month is sufficient. While precautions have been taken to prevent high
data use, the NMS system doesn’t regulate data use. Significant charges may
occur if the purchased data amount is exceeded.
• No messaging/voice is needed.
Step 3. If your SIM card is configured with a static IP, request the APN (Access Point
Name) from your cellular provider. You will need it later in the process to
configure your system for remote use.
TAKE NOTE If you would like Larson Davis to install the SIM and configure
remote communication along with your equipment order, mail your SIM card,
contact information, and APN (if applicable) to the following address:
NMS System Configuration
Larson Davis Manufacturing Center
1681 West 820 North
Provo, Utah 84601 USA
Recommended next step:
• If Larson Davis is installing the SIM card, move to 2.3 "Connecting the Gateway
to Cellular Service" on page 15. If Larson Davis is not installing the SIM card,
move to 2.2.2
