MAIN AC SWITCH

The Barracuda uses a power entry module with AC switch just next to the IEC power

cord receptacle. It can operate on 110 or 240 VAC, 50/60 Hz AC mains voltages. If the

unit is to be used with a mains voltage different to that for which the unit is supplied,

set the voltage change-over switch, which is placed inside the box, closed to the AC

transformer. The power supply socket has an integral fuse drawer containing the AC

power fuse and a spare, both of the same value (500 mA, for 230 and 110 Volts)..

DIGITAL AUDIO

INPUT (optional

)

It is baased on two connectors: a transformer balanced XLR-type connector for AES-

EBU signals and an optic connector (TOS-LINK) for fiber-optic, consumer sources.

The digital input accepts any sampling rate between 32 and 96 kHz.

No user

adjustment is necessary since a sample rate converter is built into the unit.

Furthermore, digital input automatically recognizes the digital format and the type of

connection (optic or coaxial).

SERIAL PORTS

Barracuda features up to four optoinsulated

RS232 serial ports (port 3 and 4 are

available as an option

) which allow the remote control and RDS programming both

through local - or remote PCs running the PC Smart Coder Remoter

, UECP

programmer, etc. As stated in the

UECP protocol, main parameters (access rights,

speed, etc) for Ports 1 & 2.

Port 1

(female DB9

connector)

Port for managing and control Barracuda n°1.This is the only port

available for

Firmware update and for connection to an external 56 Kbps dial-

up modem (for

remote control of Barracuda through POTS telephone lines). The Baud Rate can be

set to 2400, 4800, 9600, 19200, 38400 Baud from the Front Panel menu.

Port 2

(female DB9

connector)

Port for managing and control Barracuda n°2. Port Baud Rate can be set to 2400,

4800, 9600, 19200, 38400 Baud from the Front Panel menu. The same port may be

also set as ‘Port 1 Mirror’ to enable chain connection of multiple Barracuda

units.

The Mirror mode operates in a Monodirectional way (i.e. data received

from Port 1 are forwarded to Serial Port 2 output but vice versa is not true). See

Front Panel menu for settings.
