On Indicator: This red LED indicates power is applied to the unit.
The DDL12 provides no power switch. Power is applied by simply
plugging the wall-mount transformer into a proper AC outlet.
AC Power Cord: The power transformer provides 27 Volts AC to
the DDL12, and is detachable via a 5-pin DIN connector. The
DDL12 has two internal 'self-resetting' fuses (there are no user
serviceable parts inside the unit). If the internal fuses blow, they
will attempt to re-set after a short period. However, this may be an
indication that the DDL12 requires service.
Device #: This 6-gang DIP switch allows the DDL12 to be
assigned a specific device number. Up to 64 different device
numbers (0~63) may be assigned to allow RS-232 control of
®
multiple ADVANTAGE
products in a common system. From the
factory, the DDL12 is assigned Device # 1.
Serial Port: This 9-pin Sub-D (male) connector provides an RS-
232 Serial Port for remote control via computer or third-party
controllers (see RS-232 Control on pg. 8). The Serial Port has the
following pin assignments (left-to-right & top-to-bottom): Pin 1)
not used; Pin 2) Receive Data (RxD) input; Pin 3) Transmit
Data (TxD) output; Pin 4) Data Terminal Ready (DTR) output;
Pin 5) Ground; Pin 6) not used; Pin 7) Request To Send (RTS)
output; Pin 8) not used; Pin 9) not used. PC Control Software
and a serial cable are provided for programming via Windows
(see Setup on pg. 3). NOTE: The Serial Port can also transmit
commands received via the Logic Inputs (see Setup on pg. 4).
Link Port: This 9-pin Sub-D (female) connector provides a Link
Port for RS-232 control of multiple ADVANTAGE
RS-232 Control on pg. 8). The Link Port of one device simply
connects to the Serial Port of the next device (and so forth). Link
cables are available as an option (Biamp #909-0057-00). NOTE:
All but the final device in a system should have its 'last' switch
down (see Baud Rate) . The Link Port has the following pin
assignments (right-to-left & top-to-bottom): Pin 1) not used; Pin
2) Transmit Data (TxD) output; Pin 3) Receive Data (RxD) input;
Pin 4) not used; Pin 5) Ground; Pin 6) not used; Pin 7) not
used; Pin 8) not used; Pin 9) not used. NOTE: The Link Port
will also transmit commands received via the Logic Inputs (see
Setup on pg. 4).

Baud Rate: This 6-gang DIP switch allows the DDL12 to be
assigned a specific communications baud rate.
available are 2400, 9600, & 19200 bps. The factory default is
9600 bps. Only one baud rate should be selected at a time, by
raising the corresponding switch. The two switches on the far right
are not used. The switch on the far left (labeled 'last') is used
when connecting multiple devices in a 'Link Port to Serial Port'
configuration (see Link Port). From the factory, the 'last' switch is
up. When connecting multiple devices, the 'last' switch must be
switched down on all devices except the final ('last') device in the
system (the device with no Link Port connection).
Logic Inputs: This 9-pin Sub-D (female) connector provides eight
logic inputs for controlling the DDL12 via contact-closures (see
Logic Inputs on pg. 6). Logic Inputs have the following pin
assignments (right-to-left & top-to-bottom):
Inputs 1~8; Pin 9) switch ground. Logic Inputs are programmed
using the PC Control Software and serial cable provided with the
DDL12 (see Setup on pg. 4). From the factory, Logic Inputs 1~8
are programmed to recall presets 1~8 respectively.
Input: These plug-in barrier strip terminals provide a balanced
line-level input. For balanced connection, wire high to (+), low to
(-), & ground to ( ). For unbalanced connection, wire high to (+),
and ground to both (-) & ( ). Input gain is adjusted via software or
RS-232 control (see Setup on next page).
Output 1 & Output 2: These plug-in barrier strip terminals
provide the two independently delayed balanced line-level outputs.
For balanced connections, wire high to (+), low to (-), and ground
to ( ). For unbalanced connections, wire high to (+) and ground to
( ), leaving (-) unconnected. Signal level will be reduced by 6dB
when outputs are unbalanced.
