procedure. To quit the test sequence and start normal keyboard
operation, unplug the unit and reapply power.
Speaker Test
This test performs an audible check of the keyboard speaker.
An audio tone signal is sent to the speaker and is stepped
through the frequency range of the speaker. During this test
the CAMERA display shows the message SOUND. This test
is repeated until the test sequence is manually advanced. Push
the TEST SWITCH button to advance to the LED tests.
LED Lamp Test
The first LED test simultaneously illuminates all segments of
all LED's in the four keyboard displays. When all the LED's
are illuminated, push the TEST SWITCH button to advance to
the LED Brightness test.
LED Brightness Test
In this test, all LED's in the keyboard displays are dimmed
simultaneously (but not turned off), followed by all LED's
brought to maximum intensity. The brightness test is repeated
continuously until the test sequence is manually advanced.
Push the TEST SWITCH button to advance to the Seven
Segment LED test.
Seven Segment LED Test
This test simultaneously illuminates each LED element of all
18 LED's for a brief interval. The sequence first illuminates
the top segment of all LED's simultaneously, for a brief period,
then the next segment of all LED's, until all seven segments
have been illuminated. This test is repeated until the test
sequence is manually advanced. After all seven segments of
the LED's have been illuminated, push the TEST SWITCH
button to advance to the Joystick check.
Joystick Calibration/Speed Check
This test performs a check of the joystick center position and
its movement. The joystick center position is checked to
determine if it is properly calibrated. When the joystick is
moved in each direction, its position is monitored and
displayed continuously. The ENTER and CAMERA displays
show the direction and amount of movement of the joystick.
ENTER Display
During the joystick checks, the ENTER display shows a pair
of message codes. These codes are displayed in the four
LED positions of the ENTER display, as shown below.
Center Position Display:
Movement Display:
When the joystick is centered, two dashes are displayed as
the message codes: the first (left-most) indicates the center
of panning movement and the second (right-most) indicates
center of tilt. If the dashes are not displayed when the
joystick is centered, the joystick is not properly calibrated.
When the joystick is moved in any direction, each dash is
replaced by a 2-digit movement code. The second digit of
the left code indicates the horizontal (panning) direction of
movement, L (left) or r (right); the second digit of the right
code indicates the vertical (tilt) direction of movement, U
(up) or d (down). Each of these direction indicators is
preceded by a number, from 1 to 8, representing the speed in
that direction. For example, the message "8 L 1 d" indicates
that the joystick is being held to the left, at the highest speed
position (furthest from the center), and downward, at the
slowest speed position (closest to the center).

CAMERA Display
During the movement checks, the CAMERA display also
shows two message codes. These codes are displayed in the
six LED positions of the CAMERA display, as shown below.
CAMERA Display:
The three left-most digits display a numeric value, from 0 to
255. This value represents the panning position of the
joystick, with 128 being the center position. As the joystick
is moved left, the value increases; as the joystick is moved
right, the value decreases. The three right-most digits show
a similar numeric value for joystick tilt positions, with 128
being the center position. As the joystick is moved down,
the value increases; as the joystick is moved up, the value
decreases. (Due to variations in components and voltage
sources, the center and end point numeric values for each
keyboard may differ by a small amount.)
When the joystick checks are completed, push the TEST
SWITCH button to advance to the Keyboard Button test.
Keyboard Button Test
This test performs a visual and an audible check of the proper
keyboard button actions.
When this test is started, each of the keyboard LED displays
shows a number representing the number of buttons to be
pressed in that section of the keyboard. The numbers
displayed in each section are:
STATUS display : 4
MONITOR display: 4
CAMERA display: 8
ENTER display: 21
NOTE: The count in the ENTER display includes the buttons
in the AUX/LENS and PRESET Sections of the keyboard.
To verify proper operation, each button on the AD2078
keyboard must be pressed once. The keyboard buttons may be
pressed in any order. When a button is pressed:
1. A distinct audible tone is sounded, verifying a proper
keyboard reading by the microprocessor.
2. The number in the associated display is reduced by one
until each button of that section has been pressed. Multiple
pressing of any button reduces the count by only one.
After all buttons are tested, push the TEST SWITCH button to
advance to the Keyswitch test.
Keyswitch Test
This test performs a visual check of the keyswitch positions.
When the test is started, the ENTER display shows either
OFF, PROG, or DISP, representing the current keyswitch
position, and the STATUS display shows the number 0, 1, or 2
respectively. Rotate the keyswitch to all three positions and
verify that all three locations provide the appropriate messages
in the ENTER display. After verification of the keyswitch
positions, push the TEST SWITCH button to advance to the
Serial Communications test.
Serial Communications Test
This test is a communications check of the RS-232/422/485
port. The test requires a loop-back connection of the XMIT
pin to the RCV pin on the keyboard output port or terminal box
(pin 4 connected to pin 5). See Typical System Connections, at
the end of the manual, page C-9, for illustration of this
connection. During this test procedure the CAMERA display
shows the message SERIAL.
A sequence of test characters is sent from the keyboard
microprocessor on the port transmit pins. This sequence is
then verified by the microprocessor at the receive pins. When
the verification is complete, a double tone is sounded on the
speaker if the received code was verified as correct. If the
proper code was not received, a single tone is sounded. (The
single tone is also sounded when the proper self-test
connection is not provided.)
After the test is completed and either tone has been sounded,
push the TEST SWITCH button to advance to the ROM test.
ROM Checksum Test
A software checksum of the ROM contents is calculated for a
manual comparison with a known checksum value. The
known checksum value is printed on a label on the AD2078
microprocessor, visible from the bottom of the unit, beside the
TEST SWITCH button.
When the test is run, the calculated checksum is displayed on
the CAMERA and ENTER displays. The CAMERA display
contains the message CS =, and the ENTER display contains
the 4-digit computed value of the checksum. Verify that the
displayed checksum value matches the checksum printed on
the label.
When the ROM Checksum test is completed, the entire test
sequence can be restarted at the speaker test by pressing the
TEST SWITCH. To exit the built-in test sequences, unplug the
keyboard wall transformer and reapply power.
