Overview
The ANC-7030 provides three functions in one rack-mounted unit normally associated
with the operation of a modern multimedia conference, auditorium or meeting room.
The unit controls a wall mounted marquee type alphanumeric status display, a pager
type RF signaling device for projection-room/auditor presentation coordination and a
synchronized battery backed clock signal output decodable by an external large format
4" X 12" time-of-day clock (Antona ANC-7020). The internal chassis hardware consists
of an Antona ANC-7852 8052 microcontroller card and an ANC-7332 real time clock
input/output card. An ANC-6090 RS422 output adapter handles transmitting the
differential signal to the external wall mounted clocks. The RS422 converter and both
cards have separate manuals detailing their hardware. An external UL listed power
supply provides all three voltages used by the chassis.

Installation
Chassis Mounting
Turn off any other equipment to be connected to the ANC-7030 including any
remote equipment before performing the installation. Never install/remove the
chassis, or any of the attached equipment, with the power applied. This could
result in permanent damage to the chassis or other connected equipment due to
static discharge.
Install the ANC-7030 chassis into any empty 1 unit high rack mount opening and
secure the chassis to the enclosure. Connect any external cabling for serial output, RF
antenna, powering or audio output before applying power.
LCD viewing Angle Adjustment
Depending upon the height the chassis is mounted at and the user's normal viewing
angle, the LCD may need to be adjusted for the best possible display contrast. There
is a small 1/8" diameter hole just below, and left, of the LCD mounting screw in the
upper left hand corner of the display. The operator may use a small single blade
(slotted) type screwdriver (metal or plastic) to adjust the potentiometer to suit the
installation. Be careful not to force the adjustment beyond the mechanical stops on
both ends of the potentiometer
1.0 Marquee Operation
There are currently three (3) fixed single word messages that the remote marquee
can display. They are displayable by pressing a numeric key (1-3) on the chassis front
panel keypad and then pressing the ‘ENTER’ key as follows:
Desired Marquee Display Keypad input
SECRET 1, ENTER
CONFIDENTIAL 2, ENTER
UNCLASSIFIED 3, ENTER
Table 1
The unit will beep whenever the 'ENTER' key is pressed as feedback to the operator
that a message has been sent to the remote marquee. Pressing the 'ENTER' by itself
will retransmit the message to the marquee provided no other key has been pressed
that is not supported (i.e. any key other than 1,2,3). The 2 line LCD display on the
Marquee/Page/Clock chassis will indicate the message currently being displayed on
line two under the line one title "Marquee". Upon powering up the chassis, or after a
powerfail, the message 'SECRET' will be transmitted by the chassis to the remote
marquee. The user should visually verify the proper message on the marquee, or
retransmit it upon a powerfail occurrence. If power is applied to the chassis first and
then to the marquee, the marquee will display the last message it received before
being turned off.

2.0 Page Operation
The hand held key-chain type transmitter sends an encoded 318-MHz signal to the
pager antenna that is connected to the rear of the chassis by way of a 50-ohm coax
cable. Pressing any of the four buttons on the hand held transmitter causes a 1,200 Hz
tone to be transmitted to the front 1/8" stereo phono type jack and to the rear mounted
RCA type connector. The transmitter's signal is encoded to minimize false signals to
the receiver. The factory default device code for both transmitter and receiver is
"oooooooo" - all 8 encoder lines open. The hand held transmitter should run for one
(1) year before battery replacement is necessary. The pager receiver is a model
RF304RM based on a single chip 4-bit encoded 318 MHz signal. The mating hand
held pager transmitters are a model RF304XT. Additional hand held transmitters are
purchasable through A-VIDD Electronics. Appendix C gives more information on both
the RF receiver and transmitter.
The front mounted stereo phone connector also has an associated level control to
adjust output for use with a stereo headset or powered stereo speakers.
The green power-on LED, located at the left-hand front of the chassis, will turn red as
a hardware indication of pager reception. The LED color change is not driven by
software, and so will tell the operator if a valid, decodable input has been detected by
the RF receiver. If the LED changes to the red color and the LCD displays one of the
decoded button input status states (see next page) when any pager button is pressed,
but no sound is heard, check that the level control is not in the full counter-clockwise off
position and that the speaker is powered and plugged into the chassis output
connector. The LCD will display a one or two letter indication on line two under the line
one title "Pg". The possible displays and interpretations are as follows:
LCD display Meaning
RRed button pushed
GGreen button pushed
YYellow button pushed
BBlue button pushed
RG Red and Green button pushed
RY Red and Yellow button pushed
RB Red and Blue button pushed
Table 2
These may be used by the person paging to tell the operator further detail on what
action he/she would like taken. This arrangement provides 7 different signals. In
addition, the user may press and hold down any of the buttons to produce a short or
long tone to the operator at the chassis location as an additional signal type.
3.0 Remote Reading Clocks
If the unit is equipped with one or more ANC-7020 remote reading large format clocks,
the ANC-7030 chassis will transmit the currently set time displayed on the LCD in
military format (00:00 to 23:59). The remote clocks are all updated with time
information each second. In addition, every 4 seconds a brightness value is resent to

Antona Corporation [phone] URL:http://www.antona.com

each individual clock display according to a user set, and stored, value from the ANC-
7030. The internal clock frequency is a compensated crystal controlled oscillator
running at 32,768 Hz. When compared to GMT (Universal Time), it should keep time
accurate to within 10 minutes / year. The time may be reset quickly from the front
panel as described in section 4.23 to eliminate any short-term drift by the internal clock.
4.0 Chassis Operation and Settings
4.1 Chassis Connections
4.11 - Powering the Chassis
The chassis is powered from a source of 110 VAC through an external power supply
that provides the +5V, +12V and -12V used by the chassis. The power supply is
plugged into the 5-pin DIN type connector on the rear of the chassis labeled "POWER".
To the right of the DIN connector is the power on/off toggle switch that
connects/disconnects all three power supplies to the chassis. When the chassis is first
powered up, a green LED (light emitting diode) on the front panel and the yellow-green
backlight for the LCD (liquid crystal display) should both light. A short tone output
should sound through any externally connected audio receiver and a sign-on message
should appear on the LCD indicating the unit title and software revision running. After
2 seconds, the unit will begin displaying time-of-day information, display any hand held
pager button(s) being pressed, output the default message "SECRET" to the marquee
and begin transmitting time and brightness information to any optional external clocks.
4.12 - Chassis Outputs
There are three output connectors on the rear of the chassis. Starting from the rear
left hand side of the chassis, the first DB-9 female connector, labeled "CLOCK", is an
RS485 differential serial interface for controlling the ANC-7020 remote mounted
clock(s). The next DB-9 male connector, labeled "MARQUEE", is an RS232C level
serial port which controls the remote mounted marquee display. Both of these DB-9
connectors have adapters which change the pinouts from the D-shell connections to a
6-pin RJ-11 modular phone type connector for CAT-5 cabling to the peripherals.
The RCA connector, the second connector from the chassis rear right hand side,
provides a fixed line-out level tone to feed into a computer auxiliary sound card input if
needed (labeled "LINEOUT"). This same 1,200 Hz tone output is available on the front
of the chassis by way of a 1/8" stereo mini-phono connector, labeled "TONE", for use
with a standard pair of headphones or externally powered speakers. Tone volume
level may be user set for this connector output with the "LEVEL" control potentiometer
located just to the right of the mini-phono connector.
4.13 - Chassis Inputs
Aside from the power supply detailed in 4.11, the only other input connector is located
on the rear right hand side of the chassis labeled "PAGE ANT" for connection of the
external pager antenna by way of a BNC type connector. The antenna input

impedance is 50 ohms for use with RG-59U type coax. This is the type of coax
commonly used for office ethernet installations.
4.2 Chassis Software Operation
4.21 LCD/keypad User Interface
For setting time, marquee message and external clock brightness a simple user
interface is provided by way of the 2-line LCD status display and a 16-button keypad on
the front right side of the ANC-7030 chassis
At any time, the user may press the "Help" button to review how to use any of the
ANC-7030 settings. In help mode, use the "Up Arrow" and "Down Arrow" to scroll
through the instructions on the LCD. Use the number buttons to get specific
instructions on the various modes. Pressing the "2nd" key will return the user to the
first level of the help mode. Pressing "Help" again will return the LCD to normal display
status operation. Pressing the "Clear" button also returns the unit to normal operation
from any data entry mode. If the user goes to either a setting or help mode, and no
button is pressed for sixty (60) seconds, the unit returns to normal operation.
4.22 Marquee Setting
. Changing marquee messages requires just 2 key presses as described above in
section 1.0 - Marquee Operation. Press 1 (secret), 2 (confidential) or 3 (unclassified)
then the "Enter" button.
4.23 Time-of-Day Setting
To set time-of-day press the following sequence: "Up arrow", "Enter". The flashing
digit indicates which value shall be changed by pressing a number key. The user may
advance or move back to any position by simply pressing the "Up Arrow" or "Down
Arrow" buttons. The user presses "Enter" to set the system clock after all digits are set.
Setting a new time to the clock will reset the internal non-displayed seconds count to 00
also.
4.24 Clock Brightness Setting
To set an individual clock brightness press the following sequence: "Up arrow", "Up
arrow", "Enter". The flashing digit indicates which clock shall be changed by pressing a
number key. The user may advance or move back to any position by simply pressing
the "Up Arrow" or "Down Arrow" buttons. The LCD displays which clock number is to
be effected and the current brightness setting. The user can select any value between
00 to turn the clock display off, 01 for the dimmest setting and 15 for the brightest. The
number range represents LED "on" time in fractions of 1/16. Note that when the clock
is set for 00 - display off, it will appear as if the clock is not working when actually it is
just being set for 0 "on" time. As in setting the time, the user presses "Enter" to
complete the new brightness setting. The user need only set the desired brightness
setting once for each clock. Upon system power up all brightness values will be

restored from an EEROM (electrically erasable read only memory) installed within the
chassis and retransmitted to each clock at a four (4) second interval. This also means
that when the clocks and/or chassis is first powered up, it may take up to four (4)
seconds for the current brightness setting to be received by the remote clock.
4.25 Clock LED Test
This mode is mostly for factory use. Its purpose is to turn all LEDs on for one (1)
minute, and then return to normal clock display operation. Once this mode is entered,
the user may return to normal operation by pressing the "Clear" button.

Appendix A - Clock Protocol
The RS422 serial output to the remote mounted clock(s) is fixed at 2400 Baud, 8 data
bits, one stop bit and no parity. Transmission of time-of-day to all clocks is
synchronized at 1 second intervals. Individual brightness settings are transmitted
addressed to each clock 1/2 second after a time-of-day transmission. Data, whether
time or control information is fixed at 6 bytes as follows:
Byte # Description
1Sync Code (CCH)
2Unit Address - 00H to 08H (All=80H)
3Control Code*
4Data byte 1 (hours/brightness)
5Data byte 2 (minutes)
6Checksum - sum of bytes 2-5 modulo 8,
1's compliment
* - the control codes are as follows:
21H = set clock time of day with bytes 4/5 (packed BCD)
20H = set clock brightness with byte 4 lower nibble (binary)
31H = set clock test LED mode - turn all LEDs on
A typical serial transmission of time data would be as follows:
CCH 80H 21H 12H 34H 0AH
This would display "12:34" on all connected and powered ANC-7020 units.
