1. EQUIPMENT: An Introduction
DATIS, DA6U6 is an ATIS recorder, providing an Air Terminal Information System that uses digital
recording and message playback techniques eliminating the wear and tear problems of mechanical
systems and thus increasing the reliability and availability of the service.
The DA6U6 is a desktop version
of DATIS which is operated at
the front panel controls,
It has a LEMO connector on the
front of the DM2 for the user's
headset.
Both Voice stores have
Alphanumeric Status Displays.

RECORD
RECORD
The message text is recorded by the operator and is retained in a VOICE STORE, when the message
is recorded and checked it may be put into service as being the current information.
The P. A. Communications "DATIS" provides a continuous flow of spoken information by replaying a
recorded message. The process of storage and replay of the text involves NO MOVING PARTS.
NATO Stock No. 51 RA 0160548
There are TWO IDENTICAL voice stores contained within the equipment.
One of the two stores is selected for providing the message for transmission and is termed the
"ONLINE STORE", the other store is available for preparation of further messages, (without disturbing
the online transmission) and is referred to as the "STANDBY STORE".
The press button switch panel is used both for preparing stored messages and to make the selection
of which store should be Online. Changeover, once initiated, occurs at the completion of the message
currently being transmitted.
A key operated switch on the DATIS front panel is used to select / deselect the set of press
buttons. The panel is marked "LOCKED" and "ACCESSED", it should be in the "LOCKED"
position for automatic PATSI operation.
Both the Audio Output and the "off-air" input have telecommunications line interfaces, approved for
connection to B.T., in order that distant transmitter or receiver sites may be used.

When used manually the messages are recorded using the operator's headset.
The selected store will continue to playback, repeating the message until the operating
requirements are changed.
When the key operated switch on the DATIS front panel is set to the "LOCKED" position it is
possible for PATSI to operate the Datis pressbuttons.
Cable 1573 connects these remote control signals from PATSI to the DATIS, in both
directions simulating both the switches and indicators of a DATIS remote control switch
panel.
For convenience, a 25 way “one to one” commercial cable is employed for 1573, fitted with
db25 connectors, one end male the other end female.
EDDS communicates via a “satellite PC” that is provided in the cabinet, taking the Ethernet
data and outputting commands via it’s serial port at 9600 baud, 8 bits data, no parity and
one stop bit.

The two multi pin "d type" connectors, marked Alarm and Conn2, are intended for
connection to PATSI, the audio voice signals from the DATIS to the ATIS transmitter are
continuously monitored and an alarm is given if the signal fails or drops to a low level.
Audio for recording
One of the two stores is selected for providing a message for transmission and is termed the
"ONLINE STORE", the other store is available for preparation of the new (or subsequent)
message, without disturbing the online transmission and is referred to as the "STANDBY
STORE".
The operator's voice is recorded when a message is prepared into either store.
The microphone of the operator's headset is used to pick up the audio, when PATSI
provides a real voice synthesis, the same route through the headset socket on the front
panel is employed.

Short interconnecting cables are fitted between the two units
The controls and indicators are via conn2, a db25 connector, this cable is fed to an indicator
booster board that is fitted inside DATIS.
The existing control switch panel and the PATSI Command board then both have access to
the Datis's "switches" and can also monitor the indicators.
The command board can be considered to be another "set of switches" that will operate the
DATIS.

The Audio Switching is arranged so that when DATIS is switched to "ACCESSED" a path
exists for the microphone signal to pass directly to the DATIS, in a "transparent manner",
the operator's headphone feed is "looped through" the LEMO sockets and remains
connected at all times.

Since the DATIS commands are issued by the press button switches, it is possible to
common the "hot" side of all the switches on a panel, feeding twelve volts to the switches to
enable the panel.
This is the function of the Lock Switch on the front panel of the DATIS.
PATSI has a command board that emulates a set of press buttons, it also has it's "switches"
connected so that they can be enabled/disabled by a single wire carrying +12 V.
Since PATSI is connected into the Datis's "remote control" socket this lock switch will also
"isolate" PATSI's ability to effect the Datis controls.
At all times it is still possible to determine the status of the Datis, owing to the fact that the
indicating leds will still operate irrespective of the positions of the lock switch.

PATSI is constructed using plug-in eurocards housed in a 3U desk-top case.
It can operate from A.C. line or from auxiliary D.C. input power.
It is a multi-processor system using entirely solid state memory ( no disk drives ).
Two processors share the task :•
the controller which communicates with EDDS,
•
the second processor controls the speech composer which provides the
audio signal that is recorded into the Datis standby store.
A press button is provided on the front of PATSI that both selects the DATIS standby store
and puts it into replay, simulating a press of two Datis buttons.
The Audio Module has a LEMO socket to suit a standard RN headset, there is a flying lead
with a matching (size type 3B) LEMO plug for connection to the front of the DATIS.

PATSI Operation
Each processor has a dedicated firmware contained in EPROM.
Composer
The composer provides the audio signal, it is a complete digital announcer on one
card, it is only necessary to change this one card in order to change the spoken
voice.
Each word or phrase ( known as a vocable ) has a unique two letter code, a
spoken message will consist of a quantity of vocables contained in a file.
The file is known as a word action list (WAL), it is stored in the composer's SRAM having been
transferred from the controller via the serial channel comms which is a serial link between the two
PATSI processors.
The firmware is called DVOX. It reacts to a small number of commands which are transmitted from the
controller via the serial channel comms. The control EPROM also contains the vocable tables that
allows the composer to recognise valid words and phrases.
Controller
The controller communicates with EDDS, it controls the DATIS with the command
board, it can both send commands to Datis and see that they have been acted
upon by examination of the led indicators.
The command board has a quantity of opto-isolators that "are lit" by the Datis
indicator booster board, mimicking the led indicators.
These opto-isolators are "read" by the controller to order to fetch Datis status.
The serial link to EDDS is fitted on this card. It is provided by a separate ACIA chip and RS232 level
converter to allow for most types of serial VDU and baud rate.
PATSI Commands.
All commands are via the serial port and are sent and received at 9600 baud.

Correct use of delays.
Delays should generally be placed in front of a vocable. e.g. CpEa
Co
Cp
Cq
Cr
32mS Pause
64mS Pause
96mS Pause
128mS Pause
Cs
Intake of breath
Cu
Cv
Cw
Cx
160mS Pause
192mS Pause
224mS Pause
Long pause + breath t = 608mS
The values of each delay is important.
As an audible example try the following.
KaJbEaAaXb
sounds strange
KaJbCoEaAaXb
sounds better
KaJbCpEaAaXb
sounds natural
whereas
KaJbKfAaXb
KaJbCoKfCoAaXb
sounds OK
sounds perfect
And using Ea again we have the best result
KaJbCpEaCoAaXb

There is no protocol test in comms from EDDS to PATSI
The input from EDDS is stated in the PA consulting Group RFQ as:"These data stream shall be packaged into a message format and the meaning of each
character code are defined in Annex A"
Having discussed this by telephone both PA Communications Ltd. and PA consulting Group
confirm that PATSI should expect raw data without any preamble or header characters but
be simply followed by an Xb at the end of the file.

where Xx=$58 $78 and Ack = $06
The DATIS is controlled by PATSI when commanded via the serial link from EDDS.
There are three main functions.
RECORD SEQUENCE
send sel-codes to build a message
and end with command Xb
STORE CHANGE SEQUENCE
command Xc
STORES OFF SEQUENCE
command Xd
4.8.1.
RECORD SEQUENCE
Send a message to PATSI, observe that either (or both) store shows RECD and has corresponding
red leds lit
Store recording logic is a function of DATIS, the record sequence from PATSI emulates the record button being
pressed.
o
4.8.2
STORE CHANGE SEQUENCE
o
CsKaJbCpEaCoAxXaLaXb
Send an Xc to PATSI, observe that once the running message has finished the on-line store has
changed. ( the priority leds will change on the Datis as soon as the command has been sent ).
o
Send a second Xc to PATSI, observe that "the other store" will also change over.
PATSI observes the led indicators for both stores, so this test has to be performed for both stores.
4.8.3.
STORES OFF SEQUENCE
o
Send an Xd to PATSI, observe that both priority leds extinguish and that once the running
message has finished both stores stop replaying.
