The AMB8350 is a high performance wireless modem providing a reliable low cost serial data communications link that can be used for many data communications applications at an exceptionally competitive price. The modem operates in the ISM 868 MHz band. The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 57.6 kbps.

The parameterisation of the RF modem is realised via serial interface by making use of PC Software ‘ACC', supplied by Amber wireless. The Serial Link interface is fully programmable from 110 bps up to 115.2 Kbps. The modem achieves a RF range of up to 2 km (at clear line of sight). Each modem may be configured to either operate in ‘Master' or ‘Slave' mode for use in a wireless network.

The modem can be configured for various operating modes to enable:

• A ‘cable-free' RS232 point-to-point link, reproducing the function of a half duplex RS232 cable.
• A RS232 point-to-point link with data verification.
• A point-to-multipoint communications link (‘Master' and ‘Slave' mode), where a single ‘Master' modem may control up to 255 ‘slave' modems.
