Document change log

Updates (changes/additions) to this NiagaraAX GPRS Modem Option - Engineering Notes document are listed below.

Updated: February 24, 2011

Changes to cover new GPRS modem option support in AX-3.6 and build 3.5.31 and higher, most notably the “full configuration” ability of a hosted station’s GprsPlatformService. A first-section Note introduces this change, and it is mentioned in numerous places in the document, with reference level coverage in About the GprsPlatformService.

Two new “Provider Configuration” properties were added: “Allow PPP Connections” and “Max PPP Active Time Before Disconnect“, which are described within sections Provider and Provider Configuration. Also, debug-level “status and runtime data” at the bottom of the configuration view is now on two separate tabs—see GPRS Status and Runtime Data tabs.

Many screen captures were also updated to reflect new properties and “tweaked” property names, the latter of which also affected the listing of many properties.
Updated: June 7, 2010

Mostly minor changes. Added notes in the SIM card section and a configuration section (Provider) about needing a username and password from the service provider. Removed references to Fox and HTTP tunneling through a JACE that was erroneously included in some “use case” figures—such tunneling is available only on a Supervisor platform. Added a new section TCP/IP configuration with GPRS modem that explains DNS servers should not be configured, nor DHCP used, on any JACE using a GPRS modem.
Updated: January 21, 2009

Minor changes, noting new “M2M JACE” platform in several places. This JACE is available with an onboard GPRS modem option, equivalent to the GPRS modem option card for other JACEs. Added descriptions for two new GPRS modem properties found in theGPRS Modem Configuration view, including one new Modem Configuration property and one new Provider Configuration property (each the last one listed), as well as a few new entries in the GPRS Status and Runtime Data tabs of that view. All relate to a “modem restart” routine implemented for a rare intermittent issue. Included also is a note in the section SMS application for GPRS that explains that the station’s SmsService can also receive SMS messages. Typos in remote SMS commands were corrected in Remote SMS commands.
Updated: October 3, 2008

Minor changes, including a repeated Note in the section Use cases for GPRS equipped JACEs that explains GPRS connection speeds are similar to that for dialup modems. Two empty “usage notes” sections were also removed in the appendix Wyless as service provider.
