DAS 8.4 Plus Installation and Operation Manual

DESCRIPTION

AES/EBU Digital, Analog Audio and Activity Sensor.

The DAS 8.4 Plus contains an 8 - 96kHz AES receiver and 24-bit D/A convert-

er. The AES receiver may monitor any one of the four AES outputs with the front

panel monitor selector switch. The AES receiver provides data integrity information

to the microcontroller, which is used to indicate a data error. The D/A converter fur-

nishes a stereo feed to the balanced analog audio output amplifier, headphone ampli-

fier and level control, along with the stereo 10-LED meter and silence sensor cir-

cuitry. The factory default time delay and restore delay is set at 10 seconds, with a

fixed signal threshold of -30dB. Upon silence detection for the user-selected time,

the serial “SS/DIG Error” status is sent. When audio returns and the restore time

delay has expired, the serial “SS/DIG Error” status is sent. The “SS/DIG Error” may

be programmed for:

• Number of seconds of silence that must be present before an alarm state is

reached.

• Number of seconds of audio presence after an alarm state before the

“SS/AES/EBU “DIG Error” led illuminates.

PIP Input:

The Parallel Input Port (GPI) provides 16 pulse-stretched parallel 5-volt

TTL/CMOS compatible inputs. The inputs are pulled high to 5 volts through a

20KΩresistor and are activated by pulling the input to ground for a minimum of

40ms. These inputs supply status to any serial polling device (when the unit ID is

set to 0, no polling of inputs is required). For all PIP inputs a pulse of specified min-

imum input duration (000 to 2.55 Seconds) causes the status to go true until the end

of the input pulse. The pulse width may vary between the specified value and 10 ms

less than that value. This allows the polling computer more time to detect an input

change.

“Open Collector” Status Outputs, 16 Port Output Control

The DAS 8.4 Plus provides sixteen open collector status outputs. The status out-

puts may be configured to operate in one of three modes:

• The status outputs follow the first eight-associated channel.

• The status outputs a one-second pulse when the first eight-associated channel is

selected.

• RS-232 serial burst mode control

DAS 8.4 Plus Installation and Operation Manual

DESCRIPTION

Serial Communication:

The DAS 8.4 Plus’s serial communication is configured for multi-drop RS-232,

allowing up to 8 - DAS 8.4 Plus’s on the same computers serial port. Burst mode

allows a computer or ASCII terminal to control and interrogate the unit. This section

defines all burst mode commands. Each burst mode commands starts with an aster-

isk (“*”). Next is a single decimal digit that corresponds to the unit (ID) address 0-

7. Following that are one or more ASCII characters specifying the command. No

carriage-return or line-feed is required to terminate the command except for those

few commands of variable length, if the maximum length is not sent. If acknowl-

edgements are enabled, successful commands are responded to with “RRR” while

errors get an “EEE” response. The syntax of each command is given below. The

syntax shows the command exactly as it should be sent, except that lower case char-

acters represent values that should be substituted:

User Programming:

The DAS 8.4 Plus programming is stored in non-volatile memory.

Configurations are set with selection dipswitches and computer commands.

Inspection:

Please examine your DAS 8.4 Plus carefully for any damage that may have been

sustained during shipping. If any is noted, please notify the shipper immediately and

retain the packaging for inspection by the shipper. The package contains the DAS

8.4 Plus, Multi-voltage “Lump-n-Line power supply, plug-in euroblock screw ter-

minal mating plugs, Installation manual, reversed modular serial cable and the 9-pin

D-Sub (S 9) adapter.
