GPRS modem option


During the AX-3.4 development cycle, a GPRS (General Packet Radio Service) cellular modem option card became available for newer JACE controllers. For the “M2M JACE” (202/602-XPR) platform, an onboard GPRS cellular modem option is also available. NiagaraAX development for GPRS support has continued during AX-3.5 and AX-3.6 to provide additional functionality. This document provides software configuration details related to the use of this JACE option.

NoteStarting in AX-3.6 and build 3.5.31 and later, a station’s GprsPlatformService now provides the full configuration interface to the GPRS modem, via its default Gprs Platform Service Plugin view. This view is identical to the “GPRS Modem Configuration” platform view. Thus, you can now configure the GPRS modem in a JACE controller using either a station connection or a platform connection.

Covered in this document is the necessary JACE platform configuration, as well as information about the SMS (Short Message Service) application and details on the GprsPlatformService. A reference section on the GPRS Modem Configuration view is also included.

Note

An appendix provides details specific to using the GPRS modem option with the Wyless Group (Wyless) as the wireless Service Provider. Topics include connectivity options, connecting as a VPN client, and an example IPSec VPN gateway configuration.

NoteOnce the GPRS modem option is installed and connects to the service provider, in some scenarios you may no longer be able to communicate to the JACE via the hardwired Ethernet LAN connection, unless your PC is on the same logical subnet as the JACE. This is a “dual NIC consequence” that may occur when the “always on PPP” mode of the GPRS modem is enabled. The actual outcome is dependent on a combination of several factors, and include both the IP configuration of the local network as well as the IP configuration of the connected service provider’s mobile network (in the case of Wyless, a VPN network). In general, avoid any “IP address range overlap” between the JACE’s local network and the service provider’s network.
