3x the load current. This makes conservation of load on +3V-C crucial. +3V-M Most of the MAC 5500 hardware runs from +3V-M. The MAX782 provides this rail from the battery via a PWM synchronous switching regulator. Moe controls +3V-M in tandem with +5V-M.
Equipment Overview: Theory of Operation +18V The Main Regulator’s 5V switching output also supports generation of a non- regulated 18V rail, which is used to provide power for the acquisition module. By providing the acquisition module with 11.5V linearly regulated power from the +18V rail of the main regulator rather than the main 12V regulator (U17), acquisition is not affected by excessive current draw from the printer motor or external loads on the COM ports (esp.
Equipment Overview: Theory of Operation VAna+, VAna- The analog output circuitry is powered by a low current switched 12V rail, provided by the Main Regulator. VAna+ provides the positive supply for the output op-amps. A charge pump voltage inverter is provided to produce an approximate -11V rail for the op-amps.
Equipment Overview: Theory of Operation CPU (Stooges) Each of the three Stooges has its own 4 Mhz ceramic resonator for use in generating their respective clocks. The Real Time Clock of the system is provided as a part of the Super I/O controller. The timing for this function is derived from its own 32.768 Khz crystal.
Equipment Overview: Theory of Operation Boot Loader In the -005 board, after power ON, the FPGA gets configured using the micro controller Curly. The FPGA emulate the boot ROM and the start up code was placed in the Boot ROM from the smart media card by the micro controller Curly. The ATMEL AT91RM9200 has built in boot program in the internal ROM.

FPGA delays. This delay compensation allows the SDRAM controller to operate reliably at very high speeds (>= 100Mhz). Format pack/unpack logic – The MAC 5500 display architecture is based on the division of pixels into static and dynamic planes. As discussed elsewhere, this technique allows the smooth scrolling of ECG waveforms across the screen while buttons, annotations and other graphics remain stationary.
Page 36
Equipment Overview: Theory of Operation access both the static (5 bits) and dynamic (3 bits) portions of a pixel separately, and simultaneously. The SDRAM bus is effectively split into a “dynamic byte lane” and a “static byte lane”. The resulting improvement in drawing algorithm speed is substantial.
Page 37
Equipment Overview: Theory of Operation maintain that speed for more than one SDRAM page (256 pixels). At page boundaries, the SDRAM must initiate a new page access, and potentially satisfy refresh requirements. Since video lines are longer (640 pixels) than SDRAM pages, some mechanism is required to smooth the flow of pixels from the frame buffer to the LCD.
Page 38
Video Waveform Scroller There are numerous ways of achieving a scrolling waveform, none of which is supported by standard LCD controllers. The MAC 5500 provides scrolling through FPGA hardware placed between the LCD controller output and the LCD panel input.
Equipment Overview: Theory of Operation Color Lookup Table (CLUT) Generally the dynamic plane is filled with waveforms and perhaps a few characters of text. The static plane often contains text messages, icons, buttons and graphics. The greater variety of object types displayed in the static plane demands a wider range of colors.
Acquisition Module Interface Overview The MAC 5500 acquisition module communication protocol is different from previous generations in several key respects: Acquisition module timing is synchronized to the system. There is no longer a need to play synchronizing games to get the system (especially the display and printer) operating at the same sampling rate as the acquisition module.
Equipment Overview: Theory of Operation of more than 80 bits of one’s (or zeros for that matter), so there is no possibility of satisfying the idle period requirement in the middle of a data packet. Because the acquisition module clock is supplied by the FPGA, receive timing errors are limited to phase uncertainty.
Equipment Overview: Theory of Operation that no interrupt support is required. The ATMEL CPU polls a ready bit to determine when the transfer is complete. BBus Interface There are several I/O functions poorly suited to direct control by the ATEML CPU, whether for reasons of software complexity or power consumption.
Equipment Overview: Theory of Operation transistor driver Q100. Full volume is achieved by driving the fundamental beep tone directly to the speaker. Half volume is achieved by gating the speaker signal with a 48KHz square wave, reducing the amplitude by 50%. The LS1 is also used by the communication board for modem sound.
ATMEL CPU UART 1. VGA LCD/CRT Interface An internal backlit LCD is home for the MAC 5500’s graphical interface. In addition, external VGA monitors are supported for stress applications. Control for a standard VGA format (640 x 480 pixels) LC display is provided by the FPGA. The board is designed to support MAC3500 LCD display also.
The +3V-EMI rail is isolated from ESD transients by FB106. Acquisition Module Transceiver / Power Switch MAC 5500 acquires ECG data with a new generation CAM acquisition module. The FPGA provides the interface logic. Clocks and commands are transmitted to the acquisition module on a balanced RS485 line.
Equipment Overview: Theory of Operation threshold the open drain output of the comparator is used to remove the gate drive from Q103 which will in turn switch off the com port power. The function of the integrator is two fold. First it allows high surge currents to exist for a short time. Secondly the integrator has a much longer recovery time due to diode CR103 which ...
R179 limits the charging current to a safe level. PS2 Keyboard Port External card / bar code readers may be connected to the MAC 5500 via a PS-2 compatible keyboard port. A small amount of 5V power is available at the connector to power the external device.
Equipment Overview: Theory of Operation Run ChkShemp: If bit 4 of Port A is high, we are Shemp. At this point we are either Shemp or Larry. Shemp has pull-up resistors on Port A so bit 4 should be high.
Page 49
Equipment Overview: Theory of Operation driving R312), with a 50:1 ratio, 15Vin = 300mV out, hence 15V full scale). Since one terminal is always zero (grounded) and the other is driven with a variable duty cycle between zero and 12V, the feedback signal is positive regardless of motor direction.
An off-the-shelf 28V 1A universal input power supply provides operating/charging power for the MAC 5500. Located in the bottom of the chassis, the power supply is disconnected from the CPU board when the lid is open. The battery connection is maintained through the hinge so the CPU board is capable of operating for a limited time with the door open.
Page 51
21V. Battery Pack The MAC 5500 uses a 15-cell nickel metal hydride (NiMH) battery pack with integral thermal sensor for charge termination detection and self-resetting thermal fuse for short circuit protection. Charge current and normal system operating power are obtained from the AC power supply.
Page 52
Equipment Overview: Theory of Operation The sole purpose for resistor R151 is to protect Moe’s ADC (AN3) pin in the case where the temperature signal TBATTERY becomes inadvertently tied to VBATT+. This can easily occur since the two pins are adjacent. Should the short occur, resistor R151 will limit the current and Moe’s internal protection diodes will clamp the voltage to +3V-C.
Page 53
Equipment Overview: Theory of Operation provides the constant current drive, and derives LED operating power from the MAX782 (U27) VL output rather than from +3V-C. Q109 level shifts Moe’s output to the level required to turn off Q108 during off periods. Software update status Moe also uses the charge LED for indicating the software update progress indicator.
