Analogue audio can be used for various configurations, including a car kit mode, portable hands free and speakerphone (with an additional output gain stage).

Five audio profiles are available for GR64 users to configure various modes of operation. Each profile is factory set to represent different modes, typical of general usage. The customer can modify profiles to optimize acoustic performance to their specific application.

The analogue inputs and outputs share common uplink and downlink chains which are multiplexed, and selectively switched by the user through AT-commands.

There five factory-set audio profiles as follows:

• Portable hands free Low-level is recommended.

• Handset

Low-level is recommended.

• Car kit

Low-level is recommended.

• Speakerphone High-level is recommended.

• Headset

Low-level or High-level can be used with headset, depending on requirements.

Portable hands free is the factory-set default profile. The modification, configuration, manipulation and storage of audio profiles is achieved with the AT*E2EAMS (Audio Profile Modification) and AT*E2APR (Audio Profile).

3.3 Mini USB Connector

The USB 2.0 interface allows the connectivity to all relevant PCs and control boards in office and industrial environments. The USB interface is a USB 2.0 full speed interface for AT-C modem functionality between the GTR64 Terminal and e.g. a PC.

There is an AT command to enable this functionality. See AT*USB in the GTR64 AT command manual. Also there is available drivers for Windows environment applications. Visit GTR64 web page at: www.matrix.es/GTR64
