1 INTRODUCTION
1.1 Description
The MLiS MLB-G4201 is a Ethernet to 3G wireless terminal designed for RJ45 communication over
TCP/IP via any readily available 3G carrier network. Overall, it is more cost and time effective to use
remote solutions to combine Machine to Machine over diverse locations without having first to establish
and invest in a huge complex network.
The MLB-G4201 wireless terminal uses the DB9 Connector to provide data communication interface
and the DC jack to provide power input. LEDs are used to indicate the status of the wireless terminal.
The MLB-G4201 wireless terminal can be used to provide a wireless communication link to many
applications, including metering, fleet and asset management, vending, security and alarm monitoring,
e-maintenance and other telemetry applications.
