About the Smart-pac T ransport Display
What is a Tram T ransport
Display?
In a Tram Critical Care Monitoring system, bedside and surgical
monitors use Tram modules to collect patient data at the bedside
area. The Tram Transport display presents the patient vital signs
and waveforms collected by the Tram module on a backlit,
supertwist LCD display. The name Tram Transport Display refers
to the display only. For more details about the Tram Transport
display, refer to chapter six in this manual.
What is a Smart-pac

If you use a Smart-pac power supply with your Smart-pac transport
display, the power supply can charge a Smart-pac battery pack
while it runs the transport display. However, it can take up to 16
hours to fully charge the battery.
Even if you use a power supply with your battery pack and
transport display, you still need to place your battery pack in a
Smart-pac battery charger at least once every four weeks, so the
battery charger can exercise your battery pack.
If the battery pack does not work with your Smart-pac display,
make sure the battery backpack on your transport display has the
latest version of software. Call your sales representative for software
updates.
NOTE
It is very important to make sure you fully charge this
battery pack before you use it on a patient.

Troubleshooting
Considerations for Special Components
CMOS Components
The Smart-pac transport display makes extensive use of CMOS
components. CMOS components are more immune to noise and
consume less power than standard TTL or NMOS components.
However , CMOS components are inherently more susceptible to
electrostatic discharge (ESD) damage than other semiconductors.
ESD damage, usually a subtle weakening of semiconductor
junctions, can range from corruption of digital memory to
catastrophic failure and can render one (or more) components
permanently unusable. Although it is more common for CMOS
components to fail from ESD damage, no semiconductor device is
completely immune to ESD damage.
The inputs and outputs of the Smart-pac transport display are
protected from ESD damage; they are no more susceptible to ESD
damage during normal operation than other devices. However, when
you service the equipment, the components within are exposed to
several sources of static electricity, ranging from human hands to
improperly grounded test equipment. For this reason, it is
suggested that all service workstations be as static-free as possible.
The following guidelines can help make your workstation more
resistant to the damage that can be caused by static electricity.
• A grounded, antistatic wristband (3M part number 2046 or
equivalent) or heelstrap should be worn at all times when
repairing assemblies containing semiconductors.
• Discharge any built up static charge before handling
semiconductors or assemblies containing semiconductors.
• Use only properly grounded soldering and test equipment.
• Use a static-free surface (3M part number 8210 or equivalent)
when working on assemblies containing semiconductors.
• Do not remove semiconductors or assemblies containing
semiconductors from antistatic containers (bags) until needed.
• Make sure power to an assembly is turned off before removing
or inserting a semiconductor.
• Do not slide semiconductors or assemblies containing
semiconductors across any surface.
• Do not touch semiconductor leads unless absolutely
necessary.
• Semiconductors and assemblies containing semiconductors
should be stored only in antistatic bags or boxes.
Although these items cannot ensure a 100% ESD-free workstation,
they can greatly reduce the failure rate of any semiconductors that
are serviced.

Troubleshooting
➔ Considerations for Special Components
Surface Mounted
Components
Plastic Leaded Chip Carriers
Surface mounted components aid in miniaturizing the Smart-pac
transport display.
Surface mounted integrated circuits have legs soldered to
rectangular pads on the surface of the circuit board, rather than
legs that are inserted into holes that go through the circuit board.
Surface mounted integrated circuits can have legs on either two or
four sides of the chip.
Surface mounted resistors, capacitors, and diodes usually have no
legs at all – conductive parts of their bodies are soldered directly to
the circuit board.
CAUTION
Surface mounted components were not designed to be
removed and replaced with standard soldering equipment. Removing a surface mounted component with a
conventional soldering iron could destroy the circuit
board. Special equipment is required to remove and
replace these items.
Plastic leaded chip carriers (PLCCs) also save space. PLCCs have
conductors on all four sides and are usually used with special
sockets. They do not have legs like a conventional integrated circuit,
but rather “loops” that make contact with the socket or circuit
board when they are inserted.
CAUTION
Removing and inserting PLCCs requires a special tool
(Burndy QILEXT-1 or equivalent). If you use a screwdriver to remove or replace a PLCC, you may damage
the PLCC or the socket.
If you must troubleshoot the circuitry under the PLCC socket,
carefully remove the PLCC. Next, carefully break out the square
socket bottom with a knife so you can probe the circuit board
below.
When you finish troubleshooting, make sure to replace the square
bottom socket before you insert the PLCC again or replace the
whole socket with the correct socket replacement part. Refer to the
appropriate parts list in this manual. The socket provides necessary
spacing between the bottom of the PLCC and the circuit board.

Replacing the LCD Display
If your LCD display is damaged, you need to order one of three
Smart-pac Display Retrofit kits available to replace it. The serial
number located on the back of the Tram Transport display
determines which of the three replacement kits you need.
To view the serial number, use the disassembly procedure provided
later in this chapter to separate the Smart-pac battery backpack
from the Tram Transport display. For an explanation on how to
read the serial number digits, refer to “Equipment Identification” in
the Introduction of this manual.
• If the product code of the serial number is “JW,” order retrofit
kit, pn 414091-001. This kit includes detailed instructions
about how to rework the display processor PCB, pn 85638002 revision M or later . If your display processor PCB is an
earlier version, the PCB cannot be reworked and must be
replaced. Call Tech Support at 1-800-558-7822 for details.
Troubleshooting
• If the product code of the serial number is “LG” and product
sequence number is from 001 to 190 (except 186), order
retrofit kit, pn 414091-002. This kit includes a new flex circuit
and LCD display. The new flex circuit is required because the
older flex circuit was soldered directly to the LCD display and
will be discarded with it. Y ou may use the disassembly
procedure included in this chapter to replace your LCD
display.
• If the product code of the serial number is “LG” and the
product sequence number is 186, 191 or later, order retrofit
kit, pn 414091-003. This kit includes only the LCD and you
may use the disassembly procedure included in this chapter
to replace your LCD display.

Problems and Solutions
Here are a couple of problems that Marquette service personnel
have encountered with Smart-pac transport displays, and
descriptions of how they solved them.
Troubleshooting
Problem:
Solution:
The transport display shows a big COMMUNICATION FAILURE
message and won’t display any waveforms.
Using the wrong connector on the transport display usually causes
this problem. Make sure that you’re plugging the Tram module into
the connector on the backof the transport display. The two
connectors on the sides do not work for the Tram module.
I
O
WRITER DISPLAY POWER
If you use the correct connector but you still see the
COMMUNICATION FAILURE message, try the following steps.
• Unplug the cable between the Tram module and the transport
display and plug it back in.
• Replace the cable between the Tram module and the transport
display with a known good one.
• Reseat the connector on the bottom of the transport display.
It connects the transport display assembly to the battery
backpack assembly, and all communication signals between
the Tram module and transport display go through it.
• The transport display is designed to withstand the rigors of
transporting patients, but sometimes connectors disconnect
and integrated circuits unseat. Disassemble the battery
backpack assembly. When you’re inside it, disconnect and
reseat all of the connectors. If you have a PLCC extractor, you
can also carefully remove and reseat microcontroller U3 on
the battery interface PCB. If this step works, make sure that
you do the Checkout Procedures listed in Chapter 4,
“Preventive Maintenance.”

Problem:
Solution:
• Take the battery backpack assembly off of the transport
display assembly, and try it on a different transport display.
Likewise, you can try a different battery backpack assembly
on the transport display assembly.
∞ If the problem is with the battery backpack assembly,
replace the battery interface PCB with a known good
one.
∞ If the problem is with the transport display assembly,
replace the display processor PCB with a known good
one.
The transport display won’t turn ON.
• Adjust the CONTRAST control on the front panel. If this control
is turned all the way down, the transport display looks like it’s
been turned OFF.
• If you’re using Smart-pac battery packs to power the transport
display, make sure they are fully charged. Make sure the
READY light lights on the Smart-pac charger before you use
the battery pack with a transport display. If the EXERCISE
light is ON for the battery, make sure that you exercise the
battery pack before you use it again (press the EXERCISE
switch by the power cord connector on the Smart-pac
charger).
• If you just bought new battery packs, they were probably
Smart-pac II battery packs. If you want to use the new battery
packs, you might have to update the software in the battery
backpack assembly to version 2A or later . The Smart-pac
Battery Backpack V ersion 002 Update Instructions (pn 403596-
034) shows you how to do this.
• Remove the battery backpack assembly from the transport
display assembly and swap these items with ones from a
working transport display.
∞ If the problem is with the battery backpack assembly,
disassemble the battery backpack assembly. Once
inside it, disconnect and reseat all of the connectors. If
you have a PLCC extractor, you can also carefully
remove and reseat microcontroller U3 on the battery
interface PCB. If this step works, make sure that you do
the Checkout Procedures listed in Chapter 4, “Preventive
Maintenance.” If it doesn’t, swap the battery interface
PCB with a known good one.
∞ If the problem is with the transport display assembly,
replace the display processor PCB with a known good
one. If that doesn’t fix it, the problem is probably in the
LCD display itself.

Display Processor PCB PN 85638
Earlier versions of the Tram Transport Display used the pn 8563800x display processor PCB. V ariable resistor R84 is used to set the
intensity of the fluorescent backlight to a consistent level in the
factory.
If you replace the LCD display assembly or any of the following
components on the display processor PCB, you should calibrate the
backlight level:
Q3 R84 R87
R100 T1 U69
Display Backlight Intensity
Adjustment
Do the following to calibrate the display backlight intensity:
1. Turn the transport display OFF.
2. Attach all cables to the display processor PCB. This includes
the cable to the backlight of the LCD display assembly, and
the cable to the battery backpack assembly.
3. Attach a digital voltmeter across resistor R100 on the display
processor PCB.
W ARNING
In the following step, apply power to the transport
display. When you apply power, the output side of
inverter T1 develops over 700 volts to dive the fluorescent backlight tubes in the LCD display assembly.
Make sure you do not touch inverter T1, connector
J828, or the bottom side of the circuit board while
power is applied.
4. Turn the transport display ON.
5. Adjust variable resistor R84 until the digital voltmeter reads
140 millivolts.

Audio V olume Adjustment
Variable resistor R31 is used to set the Smart-pac transport
displays to a consistent volume level. The speaker volume is
adjusted in the factory to a particular amplitude.
NOTE
This is not a recommended field adjustment, but be
aware that changing the speaker assembly changes the
speaker volume.
If you perform a checkout procedure on a transport display after a
repair and you notice that the alarm volume is much louder or
quieter than other transport displays in your hospital, you may
adjust variable resistor R31 to fix this problem.
W ARNING
Recheck the alarms after adjusting the speaker voltage.
Too high an adjustment will overdrive the speaker and
too low will shut off the alarms.

Checkout Procedure
Preventive Maintenance
Getting Started
Required Special Equipment
The following checkout procedures describe how to make sure the
Smart-pac transport display operates correctly. Perform checkout
procedures periodically and after you repair a transport display for
proper operation.
Y ou must use other equipment, like the Digital Display Writer
(DDW) and Smart-pac power supply, in these checkout procedures.
The checkout procedures listed here only fully test the Smart-pac
transport display. You should also perform checkout procedures for
the other equipment to make sure they operate. Refer to the
checkout procedures in the appropriate service manuals.
Throughout this procedure you must connect the transport display
to devices that you would use during normal operation. You may
already have most of these items. The only exception is that you
must connect to a patient simulator instead of a real patient to
get waveforms and vital signs.
Y ou need the following items before you can start the procedures:
✓ A patient simulator. We use a Marquette Multifunction Micro-
Simulator (pn MARQ-1) in the procedure, but you could use a
different one. If you do, you need to change some of the steps
slightly.
✓ A Tram module. We show a Tram 600A module in the
procedure, but you can use any one of these:
• Series 7200 Tram module
• Series 7200 Tram AR module
• Tram 100, 200, 300, 500, or 600 module
• Tram 100-850 A or SL module
✓ An interconnection display cable. It goes between the Tram
module and transport display. Y ou can use any of these cables:
Part Number Length (Feet) Length (Meters)
403495-001 10 3.0
403496-001 15 4.6
406468-002 25 7.6
406468-001 40 12.2
✓ A patient cable to attach ECG leadwires to the Tram module.
• If you use a Tram module with a round ECG connector, you
can use pn 9443-001.
• If you use a Tram module with a rectangular ECG connector,
you can use pn 403061-001.

Equipment
✓ A set of leadwires. Leadwires pn 403066-005 are shown in this
procedure.
✓ A blood pressure cable to connect the blood pressure output on
the simulator to the input on the Tram module.
• If you use a Tram module with round BP connectors, you can
use pn 6770036.
• If you use a Tram module with rectangular BP connectors,
you can use pn 700095-001.
✓ A Direct Digital Writer (DDW). A Series 7160 DDW is shown in
the procedure, but you can use a Series 7150 DDW as well.
✓ A DDW cable. The cable that you need depends on what kind of
DDW you use:
• If you use a Series 7150 DDW, the DDW cable is the same
type of cable that you use to connect the transport display to a
Tram module, so you’ll need one of these:
Part Number Length (Feet) Length (Meters)
403495-001 10 3.0
403496-001 15 4.6
406468-002 25 7.6
406468-001 40 12.2
• If you use a Series 7160 DDW, you need a pn 700180-001
cable.
✓ A pair of power cables for the DDW and Smart-pac power supply.

PN413780/404706
WHAT IS IN THIS CHAPTER?
This chapter describes the upper-level assembly of the Tram
Transport Display assembly. The Tram Transport Display
assembly is the front half of the Smart-pac Transport Display,
which is everything except the battery backpack assembly
described in Chapter 10.
This chapter lists the parts that make up the Tram Transport
Display assembly and provides an exploded view to show you
how they go together. PN 413780-002 replaced the -001 version
and pn 404706-100 version of this assembly. The older
assemblies are included later in this chapter.
The Tram Transport Display assembly is a part of the Smart-pac
Transport Display, which is described in Chapter 5, “Smart-pac
Transport Display.”
If the product code of the serial number is “LG” and product
sequence number is 1 to 190 (except 186), it uses the pn 413780-
001 version of the flex circuit (item 59) and LCD display (item
34).
If the product code of the serial number is “LG” and product
sequence number is 186, 191, or later, it uses the pn 413780-
002 version of the flex circuit (item 59) and LCD display (item
34).

7 Processor Display PCB
PN800814/85638
WHAT IS IN THIS CHAPTER?
This chapter describes the display processor PCB. This assembly
contains all of the active electronic circuitry in the transport
display assembly, so it does many jobs. These jobs include:
❖ communicating with a Tram module to collect patient data
❖ reading user input from the switch PCB
❖ driving the LCD display
❖ sending patient data to a DDW so it can be graphed
❖ reading battery status information from the battery interface
PCB in the battery backpack assembly, so that it can display
how much battery power is in each Smart-pac battery pack
An older version of the display processor assembly, pn 85638006 is also provided at the end of this chapter. For both
assemblies, this chapter presents the parts that make up the
display processor PCB, and provides parts location and schematic
diagrams for this circuit board.
The display processor PCB is a part of the transport display
assembly. For more information about that assembly, refer to
Chapter 6: “Transport Display Assembly.”

Theory of Operation for PN800814
Overview
Watchdog T imer
All functions on the display processor PCB are controlled by
microprocessor U5 with a clock rate of 12.5MHz set by oscillator
U4. Resistor R4 enables the oscillator output while R5 pulls the
output high when the oscillator is disabled. System application code
is stored in EPROM memory on a separate plug in cartridge. The
cartridge is interfaced with buffers U7 and U24 providing a buffered
address bus and U20 as a bi-directional data bus buffer. The 100K
pullup resistors simply provide a logic high when the output buffer
is in the high impedance state. 64K of static RAM (U1, U2) resides
on the board for system workspace. Custom logic is contained in
EPLD U3 with all address decoding and processor support logic.
DUART U30 controls all of the serial communication and reads the
system configuration switches.
All audio functions are performed either by a programmable sound
generator U27 or by sound generator PCB pn 801446-001 with an
audio power amplifier U38 providing appropriate drive levels to the
off board speaker assembly.
The video circuit is controlled by a pair of display controllers U23
and U33 each drives half of the LCD screen. Video arbitration,
address decoding and serial port selection functions are performed
by the programmed EPLD video RAM arbitrator U31.
System reset and watchdog functions are implemented by a voltage
regulator U6. The regulator asserts an active low reset pulse for a
minimum duration of 200mS after Vcc has reached 4.75V. Diodes
CR1 and CR2 allow the HALT* and RESET* lines of the
microprocessor to be pulled low with the reset line. After the reset
period, pullup resistors R10 and R11 guarantee logic high levels at
their respective pins. Should the processor assert HALT or RESET
internally, diodes CR1 and CR2 prevent contention with the
regulator. Resistor R8 guarantees that reset remains low while VCC
is falling to 0V. The system software must service the watchdog (pin
6 of U6) at a minimum of every 1.6 seconds or the regulator will
assert the reset line. Removal of resistor R9 high impedances the
WDI input of the regulator allowing it to disable the watchdog
function.
Address Decoder EPLD
Revision E 7-17
The address decoder EPLD U3 functions as the interface to all the
peripherals. This includes generating chip selects and wait states,
interfacing to the front panel switches and Trim Knob control, and
providing the logic necessary for auto-vector interrupts. The EPLD
needs a 12.5MHz clock at its GCLK input. To facilitate testing, all
the output pins can be TRI-STATED by driving the GOE2* pin high.
The address decoder EPLD provides four main functions.
• Address decode/wait state generation
• Prioritized interrupt logic
• Front panel interface
• Asynchronous serial multiplexer

Prioritized Interrupt Logic
Front Panel Interface
Asynchronus Serial
Multiplexer
Programmed into the address decoder EPLD, the interrupt logic
consists of a 4 to 3 priority encoder and additional logic to signal
the microprocessor to use auto-vector interrupts. All sources of
interrupts come from the DUART U30.
The microprocessor U5 reads the front panel switches, the Trim
Knob control, and 4 dip switches (SW1) through the 16 bit I/O port
on the address decoder EPLD. Access to the port is via the SWPORT
address. The input from the four front-panel switches, the switch
push of the Trim Knob control, and the quadrature position signals
from the Trim Knob control are all processed through an identical
digital debounce circuit. All the switch inputs must have pull-up
resistors.
Once debounced, the quadrature position signals from the Trim
Knob control are fed through a decoder and an 8-bit up/down
counter in the address decoder EPLD. The 8-bit counter increments
or decrements depending on the direction the Trim Knob control is
turned. The 8-bit counter rolls-over to 0/255 when it reaches its
maximum/minimum count.
The 7200_TM pin of the address decoder EPLD supplies the signal
used to multiplex the channel A receive/transmit lines of the
DUART U30. On power-up this pin will be set low.
Audio
For display processor 800814-001A, only the sound generator U27
was used. In version A, the ready line of the sound generator then
goes inactive which keeps the chip select active for the device. The
output of the sound generator for version A is bypassed with
resistor R25 and capacitor C155 to suppress any high frequency
oscillations in the audio amps output driver . For PCB 800814-001B
and later, a sound generator daughter boar d was used instead of
the sound generator at U27. This programmable sound generator,
either U27 with an audio amplifier (U38) or a daughter board
(801446-001) attached at U27, receives information from the data
bus via latch U28. Clocking the data into the data latch starts the
audio cycle by chip selecting the sound generator U27. Once the
sound generator is finished with its cycle, it raises the ready line
which in turn deselects the device and signifies to the DUART U30
that it is ready for another audio cycle. After AC coupling capacitor
C9, the audio signal is applied to a variable resistor R32 for volume
control. The variable resistor is set so that maximum power to the
speaker is achieved. The variable resistor R32 in conjunction with
C159 form a single pole roll-off filter at 3.18KHz. (Assuming that the
pot is set at it’s midpoint) Transistor Q7 allows for disabling of the
audio signal during non-use so that speaker buzz or hiss may be
kept to a minimum. The power amplifier driver U38 provides a fixed
gain of 20 to the audio signal level. RC networks consisting of R45,
C15 and R33, C11 provide for amplifier stability and bass boost
gain. Finally AC coupling capacitor C18 allows only the audio to be
presented to the 8 ohm 200mW bezel mounted speaker . Capacitor
C14 provides 50 dB of power supply rejection on the audio amplifier
output.

DUART and Serial
Communication
Video
All serial communication is handled by the DUART U30. A 3.6864
MHz crystal provides the local operating frequency for the DUART.
This frequency was chosen for easy derivatives of the serial channel
baud rates. This same clock frequency is buffered and utilized by
the sound generator , either U27 or the daughter board 801446-001.
A bank of DIP switches SW1 is connected to the DUART input port
for system configuration. Each switch, when closed, will pull down
an input line of the DUART . Serial communication can be to any
one of three different ports. These ports include: Tram module
through the housing, Smart-pac Upgrade Kit and the 2-inch writer.
Serial channel A talks to the Tram module exclusively. Serial
channel B alternates between the writer and the Smart-pac
Upgrade Kit. This alternation is accomplished via the DUART
control lines and a small logic section of the video RAM arbitrator
EPLD U31. See that section for further clarification. The receive
lines from the external 2-inch writer are optically isolated for
equipment isolation reasons.
The presentation of video on the LCD display is accomplished by
using a pair of display controllers U23 and U33. These devices
each represent either the top half or the bottom half of the LCD
screen. At power up, they are configured to read data from the video
RAMs and display this data on the LCD screen. The microprocessor
U5 taps into the video RAMs and places the LCD data into these
RAMs for use by the controllers. Each device is synchronized so
that uniform presentation of data to the LCD screen is
accomplished. The choice of 11.5MHz for the system clock was
made to reduce flicker to a minimum.

Video RAM Arbitrator
Video Interface
The video RAM arbitrator EPLD U31 functions as the
microprocessor U5 interface to the video RAM and as a serial
multiplexer. The chip selects for the master and slave graphics LCD
controllers (GLC) are also generated by this EPLD.
The video interface portion of the video RAM arbitrator EPLD has an
identical master and slave section. From the view point of the
microprocessor, the video RAM data is NOT contiguous and resides
at odd addresses. The microprocessor may read and write to the
video ram while the GLC can only read from the video RAM. The
video interface switches between the microprocessor or GLC
address depending on who is accessing the video RAM. When the
microprocessor reads the video RAM, the video interface
synchronizes the microprocessor read cycle with the GLC read
cycle. W ait states ar e added to the microprocessor read cycle until
the two read cycles synchronize. Once synchronized, the video
interface divides the GLC read cycle into two read cycles, one for the
GLC and one for the microprocessor. The GLC r ead cycle starts first
and latches its data into the octal latch U8 or U25. The
microprocessor read cycle starts by switching in the microprocessor
address to the video RAM via multiplexers. The data from the video
ram is routed to the microprocessor data bus via the transceiver
U21. This completes the read cycle. The microprocessor write cycle
operates identically to the read cycle except the data direction is
opposite.
Serial Multiplexer
The serial multiplexer portion of the video RAM arbitrator EPLD
provides the logic to select the appropriate receive path for receive
channels A and B of the DUART U30 as well as inverting the
AUX_XMT line. The following function tables present the data path
for the DUART receive channels B and A respectively.

On/Off Control
The power switch circuitry assumes that a pullup resistor of
approximately 50K to +5.0V is connected to the open collector I/O
line ON/OFF*. When the power switch is in the open position, the
pullup resistor dominates the open collector I/O line indicating a
logic high to the device monitoring this I/O line. The monitoring
device sources no power to the processor PCB under this logic high
condition.
When the power switch is closed, the pullup resistor is pulled low
with all of it’s current flowing through the power switch to ground.
The device now sources power to the processor PCB to energize the
board. After the board powers up, the reset pulse duration is
initiated by the voltage regulator U6. During this time that reset is
active, transistor Q6 is energized which in turn energizes transistor
Q5. The LTCH_PWR line is therefore pulled low during reset. After
the reset pulse goes high, and LTCH_PWR is asserted high,
transistor Q4 is energized. (Note that no current flows through
transistor Q4 as long as the power switch remains in the closed
position). This allows transistor Q3 to remain off and the signal
PWR_ON to go high. When the power switch opens, transistor Q4
conducts the pullup current to ground through resistor R27. This
biases on transistor Q3 pulling the signal PWR_ON low. This allows
the processor time to clean up things and shut off the contrast
circuit before logic power goes away. After these functions are
performed, the processor disables LTCH_PWR which in turn shuts
off transistor Q4 allowing the ON/OFF* line to be pulled up by the
power sourcing device. This is the signal to this device to remove the
power. If for some reason LTCH_PWR cannot be removed, the next
watchdog reset pulse energizes transistors Q5 and Q6 pulling
LTCH_PWR signal low long enough to turn off transistor Q4.
Contrast Circuit and
Control
Revision E 7-21
The necessary voltage for contrast control is derived from the DC to
DC converter U34. This converter makes ±12.0V from +5.0V input.
By tying the V+ output to ground, a span of -24V is achieved from
negative voltage to ground. Resistor R70 provides the necessary
minimum load to the converter secondary for good startup and
regulation. The VLCD_ON signal allows control over whether or not
the negative voltage regulator U35 sees any input voltage. When
active, the regulator provides a variable contrast voltage to the LCD
panel (assuming a 1K pot is connected to the appropriate PCB
pins).
