Device reset:
This command performs a "soft reset" of the Emic Platform, which resets the volume, speed, and pitch settings to
their default values. All abbreviations stored on the device will remain intact. The "Device reset" command is different
than using the external /RESET pin, which is a "hard reset" that completely restarts the Emic Platform and
reinitializes the module's control firmware.
Upon initial power-up of the Emic Platform and when the "Device reset" command is successful, the Emic Platform
will respond with "OK" or a single 0x55 byte, depending on the ASCII or hexadecimal mode of the Emic Platform.
The visible LED will be both red and green while the Emic Platform is initializing.
Analog audio input:
This command is for the SIP version only and enables the analog audio signal on the AIN pin to be fed through the
Emic Platform to either the AOUT or SP+/SP- pins. During this operation, the visible LED will remain RED and the
BUSY line will be set HIGH. This command will remain active until the Emic Platform receives a single termination
character. In ASCII mode, the termination character is a ";" (semicolon) or 0x0D byte (carriage return). In
hexadecimal mode, it is a 0xAA byte.
When the command is successful and the feed through is disabled, the Emic Platform will respond with "OK" or a
single 0x55 byte, depending on the ASCII or hexadecimal mode of the Emic Platform. The BUSY line will then be set
LOW and the visible LED will turn green.
No signal should be active on the AIN pin when it is not in use, or else the signal may bleed through to the Emic
Platform's audio output at undesirable times. The input has a nominal 694mVp-p level. No on-board gain control is
available. The audio signal must be AC coupled to the AIN pin. This pin should be left floating if it is not implemented.
Emic help:
This command prints a table of available commands. The menu will vary slightly between the OEM and SIP versions.
