Gateway hardware specifications and technical information are available in the Hardware Guide section
of this document. Information about deploying gateway firmware, configuration and software updates is
available in the Provisioning Server Guide section of this document.
Introduction
The Courier M2M Cellular Gateway from USRobotics provides LAN to WWAN and Serial to WWAN
routing and GPS functionality in a simple, cost-effective base unit. The gateway can be configured locally
or remotely from a PC,tablet, or smartphone. The USR3510 is certified on all major U.S. cellular
operators (CDMA/EvDO and WCDMA/HSPA).
The gateway is pre-loaded with an RS232 serial interface card in its primary expansion slot.
Base Unit Design
The base unit design features Serial-to-WWAN, LAN-to-WWAN, and GPS interfaces, advanced error
detection, and repair watchdogs. When a component or software process loses connectivity, the device
automatically resets or repowers itself. You can also schedule the device to reset at specific intervals to
ensure daily, error-free operation.
Finally, the device can be monitored and provisioned remotely, which vastly reduces the technician time
on site, and enables firmware updates and new software features to be deployed quickly and efficiently.
Expansion Slots
The gateway can be user-customized with expansion cards available from select electronics distributors.
The RS232 serial interface card that is pre-loaded in the primary expansion slot can be removed and
replaced with another expansion card, and the secondary expansion slot can be loaded with an
expansion card. Contact a USRobotics Sales representative for more details.
