Override Time Pin
Pin 8 is to remotely select an override silence time (default is 2min 5sec). This may be useful
for the broadcast of Remembrance Day services, or where you expect a silence of up to
2 minutes to be broadcast. The override silence time is set whilst the contact is active,
therefore a latching button is recommended. The override time can be changed via the
Sonifex SCi software.
Pin 13 is a voltage supply pin. 5V is supplied up to a maximum current of 200mA.
Pin 25 is a ground reference level.
Slave Socket
An 8 way RJ45 connector allows connection to another
RB-DSD8 unit, via RS485.
Pin 4: TX/RX -
Pin 5: TX/RX +
Pin 8: DGND
All other pins are unused.

USB Remote Control
A Type B USB socket carries a standard Universal Serial Bus interface via which advanced
configuration options may be set and many functions may be remotely controlled.
The RB-DSD8 will interface directly with personal computer USB ports using a standard
USB cable. On first connection, you will be prompted to install the necessary USB driver
(supplied), following which the USB connection behaves as a “virtual serial port” with
identical data format and command protocol as the RS232 remote control interface.
Ethernet
The 8-way RJ45 socket connector carries a standard Ethernet interface and allows
connection to a local area network. The pin assignments are as follows:
Pin 1: Receive data+
Pin 2: Transmit data+
Pin 3: Transmit data+
Pin 6: Receive data-
Pin 5: Ground
All other pins are unused.
Wordclock & AES Synchronisation Input
This BNC is used as a digital input and has an impedance of 75Ω. The input is autosensing
and can be used to provide an external synchronisation signal from an AES3 source or from
a TTL wordclock.
Dual IEC Main Inputs
The RB-DSD8 has 2 mains inputs for power supply redundancy, which provides protection
against a single point of failure on the internal power supply units, and, if distinct sources
are used for the mains inputs, it will also protect against a mains input failure. The inputs
are rated at 2A and will accept a voltage range of 85V to 264VAC.
