Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

Like the display, the overall functioning of the CPU can be confirmed by a simple test.

1.Locate the CPU board on the mother board by referring to Figure 2-5.

2.Power the instrument on.

3.Locate the red LED at the top left edge of the board.

4.It should be flashing at a frequency of about once per second.

5.This flashing indicates the board is powered up and is executing instructions.

Testing and operation of the CPU RS-232 port is described in Section 9.3.2. It is possible for the UART driver chip to malfunction in either the input or output port or both.

9.3.1.3 Front Panel Keyboard

The keyboard consists of 8 keys and 3 LED's. Key strokes are sent to the SBC40 computer's parallel port. The computer software detects the key strokes via interrupts. The bottom line of the display consists of 40 characters which is divided into 8 - 5 character fields. Each field defines the function of the key immediately below it. The definition of the keys is variable and depends on the menu level of the software.

To check the operation of the keyboard, each key should perform an operation indicated by its current definition shown on the second line of the display.

Example #1 - testing key#1 (left most key).

At the top level menu key #1 is defined as the TEST function. Pressing this key should cause the middle field of the top line of the display to show the various test functions.

Example #2 - testing key #8 (right most key). At the top level menu key #8 is defined as the SETUP key. pressing key #8 should cause the SETUP menu to be displayed.

Example #3 - If the 5 character field above any key is blank, the key is not defined, pressing the key has no effect.

The 3 status LED's indicate several functional states of the instrument such as calibration, fault, and sample modes. The state of the LED's is controlled by 3 lines on the parallel port of the SBC40. Functioning of the LED's can be checked by:

1.Turn off the M200AU power.

2.While watching the LED's, turn on the instrument power.

3.When the power comes up, the computer momentarily applies power to all 3 LED's. If all the LED's are observed to light, they are working properly.
