1 INTRODUCTION
1.1 Description
The MLiS MLB-G1102 is a Dual Band 2G wireless terminal designed for RS232/RS422/RS485
communication over TCP/IP via any readily available 2G 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-G1102 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-G1102 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.
