Connection and Setup of the AD2089
12 AD2089 Operator’s Manual
Note
The count in the ENTER display includes the keys in the ENTER, MULTI-FUNCTION, and
CONTROL sections of the keyboard, as well as the “flip” button on the joystick.
To verify proper operation, each key on the AD2089 keyboard must be pressed once. The keys
can be pressed in any order. When a key is pressed.
• An audible tone is sounded, verifying key recognition by the keyboard's microprocessor.
• The number in the associated display decrements by one. Pressing the same key multiple
times will not decrement the count by more than one (although the audible tones will
continue).
• When all keys have been pressed (including the joystick flip button), each display section will
show a zero.
Press 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 the current keyswitch position (OPERATE, PROGRAM, or MENU), and the SITE
display shows the number 0, 1, or 2 corresponding to the respective keyswitch position.
Rotate the keyswitch to all three positions, and verify that each of the three locations provides the
appropriate message and number. Following verification of the keyswitch positions, press the test
switch button to advance to the serial communications test.
Serial Communications Test
This test provides a communications check of the keyboard's RS-232 serial port. The test requires
a loop back connection of the XMIT pin to the RCV pin on the keyboard output port, or on the dual
terminal block (pin 4 connected to pin 5 on the J1 side only). During this test procedure the
CAMERA display shows the message “SERIAL”.
A sequence of test characters is sent from the microprocessor's transmit port to be verified at the
processor's receive port.
• If the test sequence is verified as correct, a double tone sounds on the speaker.
• If the test sequence is not verified, or if the test connection is incorrect, a single tone sounds
on the speaker.
After completing the serial communications test, press the test switch button to advance to the
ROM Checksum test.
ROM Checksum Test
In this test a software checksum of the ROM contents is calculated for comparison with a known
checksum value. The known value is printed on a label on the AD2089 microprocessor. The label
is visible on the bottom of the unit, adjacent to the test switch button.
When the test is run, the CAMERA display shows the checksum message CS =, and the ENTER
display shows the four digit computed value of the checksum. Verify that the displayed checksum
value matches the checksum printed on the label.
