10.3.1.2 Single Board Computer

The SBC40 is a full function computer designed for instrument control applications. It consists

of a microprocessor, 2 serial and one parallel ports, standard bus interface, and 4 sockets for

memory. The memory sockets consist of: 256k ROM containing the multitasking operating

system and application code, 32k E2PROM containing the setup variables, 256k RAM

containing data collected by the instrument, and a time-of-day clock to provide event timing

services. The overall function of this board is quite complex. Complete testing of this board's

functions is not possible in the field. If component level troubleshooting of this board is

necessary, contact the factory for schematics.

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 on the instrument.

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.

RS-232 diagnostic procedures are described in Section 4.3.1.2. It is possible for the UART driver

chip to malfunction in either or both of the input or output ports.
