1. Introduction
This manual provides information for interfacing the RV50(X) Sierra Wireless AirLink® 4G LTE
Cellular Modem to Campbell Scientific dataloggers.
The RV50(X) digital cellular modem is manufactured by Sierra Wireless® and supports network
operator switching based on the SIM(s) for use on GSM (Global System for Mobile
Communications) and CDMA (Code Division Multiple Access) networks. The modem is accessed
through the Internet using TCP/IP communications protocol.
Use of the RV50(X) requires a VerizonLTE or AT&T® HSPA+/LTE business account or an
equivalent account from Campbell Scientific or another service provider. For more information,
see Establish cellular service (p. 3)
NOTE:
The RV50 also supports Verizon® CDMA/1xRTT/EVDO and AT&T®HSPA+/LTE accounts.
For additional information on the RV50(X) module, see the Support section of the Sierra Wireless
website.
Before using the RV50(X), please study:
l Safety (p. iii)
l Initial inspection (p. 2)
l Pre-installation (p. 3)
l QuickStart (p. 8)
The RV50(X) module may be configured in one of two ways, depending on the communications
type and needs of the user. ACEmanager, a web based configuration tool is hosted by the RV50
(X). It can be accessed using a web browser over the cellular WAN or locally over Ethernet. A
number of templates will be provided for download to make most configurations very simple
once connected to ACEmanager.
For many applications, the preferred module setup is Point-to-Point Protocol (PPP) mode. In this
mode, the module simply passes IP communications directly to the data logger. This enables
features such as FTP, HTTP, and emailing. QuickStart (p. 8) describes setting up the module for
PPP mode. See the EmailRelay() paper and Blog article with example programs for more
information on emailing.
Alternatively, for applications that just need a connection for data collection and data logger
maintenance or monitoring, setup as a serial server is sufficient. In this mode, the module
