Pneumocheck Handle Printer/Charger 31

The two inverters connected to the CPU pin 23
functions as a latch which powers up in the low state but
which can be forced to a latched high state by software.
It is used to provide a reliable mechanism by which the
software can distinguish between power-up reset and a
reset caused by the front panel reset key.

The three inverters connected to CPU pin 20 provide
enough drive to illuminate the front panel “ready” LED
directly.

The alarm device is an electromagnetic transducer. It
requires a transistor to drive it. D1 clamps inductive
surges.

Communication with the spirometer is handled by
protected direct UART connections. The signals are
standard asynchronous ASCII at 4800 baud, however,
the levels are CMOS logic levels, not RS232 level.

The printer power supply provides 24 volts at 3 amps
peak. 5 volts at 200ma, and 14 volts at 100ma.
The 24 volts output is regulated with a switching power
regulator while the 5 and 14 volt supplies utilitize linear
regulators. The present design incorporates a
transformer that allows a primary voltage of either 90 to
132 vac or 200 to 275 vac.

The switching regulator IC has a maximum allowable
supply voltage of 50 volts. The minimum output voltage
for the 24 volt supply that will ensure proper printer
operation and print contrast is 22 volts. Using a
transformer with a nominal 25 volt secondary and a full
wave bridge rectifier result in a voltage range of 27 volts
to 43 volts at the regulator when the input voltage varies
through the specified range.

The switching oscillator frequency is determined C17
and R32 which were selected to provide a 20Kh rate.
