Description

The AMB8350 is a powerful OEM radio data modem enabling cable-free and

reliable transmission of data over medium distances. The embedded

microprocessor controls the complete wireless data communication, thus

handling packet and checksum formation, addressing, monitoring of channel

access and resending of unacknowledged data packets. A buffer memory is

provided to enable transmission and reception of data independently of the

connected host controller. The radio modem can be used as a transparent

cable replacement.

The AMB8350 features a command set of various transmission modes to

meet the requirements of the respective application. It provides a broadcast

operation mode and it enables the user to address up to 254 devices per

channel.

The GUI for the freely available Windows application AMBER-ACC makes it

easy to set the operating parameters. The configuration of the parameters

can alternatively be realised by means of AT-commands.

Interface

The AMB8350 is connected to a host system via RS-232 interface with data

rates of up to 115.2 kbaud. Alternative host interface options: RS-485 or

USB.

Scope of Application

Telemetry, wide-ranging data collection systems, monitoring, surveying,

remote control and wireless sensor networks.
