System overview

Overview

A transmitter is directly connected to the patient and transmits monitored data via the antenna to a corresponding receiver in a one-to-one correspondence between transmitters and receivers. Up to 16 receivers (four quad receiver modules with four receivers on each) may reside in a receiver system. Up to four quad receiver modules connect to the receiver backplane PCB, which is responsible for managing communications between all connected receivers and the telemetry host application software on the PC. The communication between the PC and the receiver backplane is 10BaseT Ethernet and is called the Receiver-Exchange (RX) network. The host application software processes the patient data from the receivers and makes the patient’s ECG parameter and waveform data available for display at network viewing stations or the Clinical Information Center (CIC) central station.
The ApexPro telemetry system consists of the following components:
Patient monitoring equipment
Apex oximeter (optional) Xpod oximeter (optional) Accutracker DX noninvasive blood pressure monitor (optional) DINAMAP PRO 100, 200, 300, and 400 series monitor (optional)

Equipment Overview
035B
The DC power requirements for the ApexPro antenna system depend greatly on the configuration of each individual system. To ease the power requirements of the ApexPro telemetry system, the power supply for the antenna system is external to the ApexPro receiver system and separate from the antenna.

Interface with ApexPro receiver subsystem

Each receiver in the quad receiver module, located in the receiver subsystem, receives data from the transmitters. This data is processed by the receiver system and then transmitted via the dedicated Ethernet interface to a CIC Pro center for further processing and display. The quad receivers and the receiver subsystem together are known as the receiver system.
The interface between the antennas and the receiver system consists of coaxial cabling and connectors for transferring the transmitted signal. The interface uses 75­ohm cable from each antenna field and F style 75-ohm connectors as a connection medium. The preferred cable is RG-6, but for longer lengths RG-11 may be used.

Interface with multiple ApexPro receiver subsystems

To interface the antenna system with multiple ApexPro receiver systems, each antenna field in the antenna system is split into the appropriate number of tap points using combiners/splitters before connecting to each ApexPro receiver system.

Equipment Overview

ApexPro antenna system

Antenna
The antenna system is used for transmission of data from the transmitter to the receiver system.
The antenna is a circularly-polarized array of sloping half-wave dipoles with an omni­directional coverage pattern. The antenna is available in two versions: active and passive. An active antenna includes an active amplifier, while a passive antenna provides no signal amplification. The receiver antenna comes with a standard drop ceiling T-bar mount.
Antenna amplifier
The antenna amplifier boosts the signal when losses from other antenna components exceed the gain of the antenna. DC power for the amplifier is obtained from the +12VDC power supply.
Coaxial cable
Splitters/combiner
Attenuators
Power supply
Coaxial cabling is used to connect the omni-directional antennas and amplifiers to the receiving equipment. Controlled-impedance cabling is used and 75-ohm, RG-6 type is recommended. Plenum- or riser-rated cable is used to meet NEC fire codes. RG-11 may be used if cable lengths become long and dB losses become excessive.
Passive splitters/combiners split or combine the RF signal into multiple paths. The same splitter may also be used as a combiner to join multiple RF signals into one path. There are two-, four-, or eight-way splitters available that are DC-passive.
Attenuators lower signals and balance antenna runs. The attenuators are DC-passive and are available as 3 dB, 6 dB and 10 dB attenuators.
A +12VDC power supply at 1A supplies power to the antenna system. Power supplies accept AC voltages between 90-270VAC. AC inputs have internal fuses that are not replaceable. The output of the supply is short circuit protected.
Bias tee
The antenna bias tee allows the injection of DC power from the antenna power supply into the antenna system cabling. The bias tee supplies RF isolation between the RF signals on the antenna cabling and the power supply. It contains a DC block that
2-4 ApexPro™ 2001989-351A
Page 25
Notch filter
Bandpass filter
Identify antennas
Equipment Overview
blocks the conduction of DC power to the receiver system and associated hardware. A bias tee is used with each power supply.
Notch filters are frequency or TV channel specific and notch out the TV video, audio, or digital center of the band signals. Notch filters also filter pager signals or other strong RF signals that can be found in a telemetry environment.
The bandpass filter rejects frequencies outside its listed bandwidth and passes frequencies inside its listed bandwidth. It is used in place of certain notch filters to provide wide band filtering with less in-band loss than multiple notch filters.
Identify the high-power and active antennas by the part number label and the GE logo only on the front (bottom). The passive antenna looks identical to the high-power antenna except it has a black cap over the LED power indicator. To visually identify the antenna type, observe the following:
The -002, -003, -004, and -005 models have an embossed GE logo. The -006, -007, and -008 models have a blue GE logo. The -003, -005, and -006 passive antennas have a black cap over the LED power
indicator.
For further identification, check the part number label.

Equipment Overview

NOTE
The telemetry system supports 2 SpO2 oximeter modules:
Apex Oximeter Nonin Xpod Oximeter
Theory of operation - pulse oximetry
Pulse oximeters shine light (red and infrared) through perfused tissue and detect the fluctuating signals caused by arterial blood pressure pulses. Well-oxygenated blood is bright red, while poorly oxygenated blood is dark red. The pulse oximeter determines functional oxygen saturation of arterial hemoglobin from this color difference by measuring the ratio of absorbed red and infrared light as the blood volume fluctuates with each heart beat. Since steady conditions (steady venous blood flow, skin thickness, bone, finger nails, etc.) do not cause fluctuations, they do not affect the saturation reading.
Mathematically:
Anything that affects the intensity of the light such as thick or colored skin affects the maximum and minimum proportionally and thus the ratio minimum/m ax im um does not change. However, if too little light gets through, the pulse oximeter does not function.
Pulse oximeters use 2 different wavelengths of light (colors) and thus have the ability to determine 1 component of blood. Pulse oximeters are calibrated to closely approximate functional oxygen saturation values. Pulse oximeter oxygen saturation values will closely approximate laboratory instrument fractional saturation values if the dysfunctional hemoglobin saturation levels are negligible. If the dysfunctional hemoglobin is carboxyhemoglobin or methemoglobin, then the difference between the oxygen saturation value displayed by the Pulse oximeter and the oxygen saturation values determined by the laboratory instrument are greater as the dysfunctional hemoglobin levels rise approximately in accordance with the following formulas:
801
2001989-351A ApexPro™ 2-15
Page 36
Equipment Overview
SpO2 = O2Hb + COHb + MetHb SaO2 = 100 x O2Hb /(100 - COHb - MetHb)
Where:
SpO2 = Pulse oximeter determined and displayed oxygen saturation in percent O2Hb = Fractional oxyhemoglobin saturation in percent COHb = Carboxyhemoglobin saturation in percent MetHb = Methemoglobin saturation in percent SaO2 = Functional oxygen saturation in percent
The following table gives examples of the oximeter readings:
Example 1 Example 2
O2Hb = 96 O2Hb = 88 COHb = 0.5 COHb = 8 MetHb = 0.6 MetHb = 2 SpO2 = 97 SpO2 = 98 SaO2 = 97.07 SaO2 = 97.78
The mathematics are fixed in the pulse oximeter hardware and software. Thus, no field calibrations are needed or are possible. There are no adjustable parts within the pulse oximeter that affect the calibration.
The function f, depends on the wavelengths of the sensor LEDs. These wavelengths are fixed by specified manufacturing processes and materials. The sensors are checked for correct operation before shipping, so no adjustment or calibration is needed or possible.
Because the pulse oximeter does all critical computations in software and there are no critical parts to drift; no re-calibration is needed.

ApexPro receiver system

Overview
The Receiver System receives RF signals from the four antenna inputs. These inputs are for four separate, overlapping fields. The system performs the following functions:
filters RF (backplane) distributes RF to quad receiver modules (backplane) demodulates and decodes transmitter data (quad receiver modules) retrieves decoded data (backplane) packetizes and sends data out over RX network (backplane)
The asynchronous serial communication port is for diagnostics, service and installation information.
2001989-351A ApexPro™ 2-17
Page 38
Equipment Overview
The RX network is directly connected by a network crossover cable to an ApexPro Telemetry System. The RX network should not be tied to any other network.
Receiver subsystem (backplane)
The subsystem provides an interface between the quad receiver modules and the telemetry software running on the ApexPro Telemetry System connected via 10BaseT Ethernet. The subsystem accommodates up to four quad receiver modules. The subsystem performs the initial amplification and filtering necessary on the RF input signals from the transmitter.
Quad receiver modules
The quad receiver module receives the GMSK modulated RF signals from the transmitter through the receiver subsystem (backplane). The RF signals are mixed to an intermediate frequency, filtered, and mixed again to baseband and re-filtered. The baseband signal is separated into its in-phase and quadrature components then sampled. The DSP takes the samples, demodulates, corrects, and decodes packets of TLINK data. The information is passed on to the receiver subsystem for furthe r processing and transport over Ethernet. Each module has four functionally identical receivers.

Infrastructure installation

Overview

This chapter provides direction for how to install specific parts and gives guidelines for specific tools to use for installation.

Install coaxial cable

Installation guidelines
Use the hospital scaled prints and the logical antenna schematic to install the cabling. The logical antenna schematic is generated by ND&I.
Keep the following in mind when installing coax cable.
Always follow the National Electric Code regulations. Always use PVC for the feed-throughs. Do not kink the cable. If the cable is kinked, cut out the kinked part and reattach. Do not pull cable over any metal edges or other abrasive surfaces. Do not pull cable for one room at a time. The entire cable spool should be
accessible and multiple runs should be pulled at the same time into the ceiling.
Do not lay cable on top of light fixtures. Lay out cable uniformly and with excess slack. The slack should consist of about
25 cm (1 foot) or so every 3 m (10 feet), both horizontally and vertically.
Do not coil up any extra cable, but instead increase the amount of excess slack
throughout the entire length of cable.
Coaxial cable preparation
These sections describe how to strip coaxial cable and crimp connectors to the cable. Below are descriptions of the components of a coaxial cable.
1 Center conductor — The center-most feature of coaxial cable. It consists of solid copper
or copper-clad aluminum wire.
2 Dielectric — An electrical insulation utilized to maintain position of the center conductor.
It is composed of polyethylene in either solid or foam state. This insulator/positioner may
3-2 ApexPro™ 2001989-351A
also be evenly spaced solid polyethylene discs.
200A
Page 43
Strippers and crimpers
Installation and configuration
3 Outer conductor or foil — Either solid aluminum tube or an aluminum foil wrap. The cable
size is usually derived from its outside diameter.
4 Braid — Interwoven strands of aluminum or copper mesh. It extends the conductivity of
the outer conductor to the sleeve of the connector.
5 Jacket — The black polyethylene coating over the aluminum outer conductor protects it
from scratches or abrasions during handling and provides a weather-tight seal. The jacket on plenum cable is made of teflon specified by fire codes.
Recommended tools
The following table indicates the recommended cable strippers and crimpers.
NOTE
The CT611QS will work for both RG-6 Riser and RG-11 Plenum cable. The current RG-11 crimper will work with the new RG-11 cable and
connector.
The old RG-6 Riser crimp tool will work for the RG-6 Plenum. Italics = preferred tool.
Following the descriptions is a section describing how to correctly strip coaxial cable. RG-6 is the recommended coaxial cable, but RG-11 cabling is used for some installations.

Installation and configuration
NOTE
Be sure that after planning and designing the antenna system, the Penetration Check test (described in the ApexPro Antenna System Installation Test Instructions) is completed. It is used to estimate the RF penetration of the hospital construction.
The standard installation for antennas uses a T-bar mount connected to the drop ceiling support. The retaining clip and pin come with the antenna.
For ceiling tile or dry wall mounting, see Optional antenna mounting kits on page 6-3 to order additional hardware kits necessary for these mounting options. All antenna mounting installation options and instructions are described in the ApexPro Telemetry Antenna Mounting Instructions that are included with the antenna.
NOTE
For customer site reasons, some antennas may require installation above the ceiling. Antennas cannot be mounted in a plenum air shaft, since the antenna is not plenum rated. For specific guidance on above-ceiling antenna mounting, contact the Network Design and Integration (ND&I) team.

Install antenna amplifiers

Antenna amplifiers are installed to boost the signal levels from the antenna. The installation location for the antenna amplifier is generated by the ND&I team for each site installation.

Programming the transmitter for use

Before use, the transmitter must be programmed. The transmitter is programmed or upgraded in the field to:
select the operating frequency and corresponding TTX number select the reference lead set the alarm pause time select the filter setting change the serial number download new software
Refer to the ApexPro Telemetry Frequency Chart Reference Manual for the operating frequencies and the corresponding TTX ID numbers.
Refer to the Transmitter Programming Box Programming Instructions for details.

Transmitter configuration

Program code storage

Executable program code for the main processor is stored in non-volatile programmable memory. Program code can be changed via an interface connector port using the PC-based programming box software or a HyperTerminal program and a programming box. The version of the currently stored transmitter code can be displayed using the transmitter programming box software kit. See Apex, ApexPro and ApexPro CH Transmitter Programming Instructions.

Error log

The transmitter contains an error log in its non-volatile programmable memory. When a synthesizer lock error occurs, this is logged and latched into the appropriate memory space. When a checksum error on start-up occurs, this is logged into the appropriate memory space for this as well. The error log can be viewed using the programming box PC software or a HyperTerminal program. This reports both of these errors as well as a real-time report of the synthesizer lock status.

Parameters

Using HyperTerminal or the ApexPro PC programming box software, certain transmitter parameters can be viewed and some can be changed while in service mode.

Visual inspection

Inspect for damage

The following steps check for obvious damage.
General
Inspect the equipment (transmitter, receiver, etc.) case for cracks or other
physical damage. Do not use a transmitter that is damaged. Refer all damaged equipment to qualified personnel.
Inspect all external connections for loose connectors or frayed cables. Have
any damaged connectors or cables replaced by qualified service personnel.
Transmitter
Inspect the transmitter case for damage that may affect the environmental
seals (such as if the unit was dropped and the case seals opened as a result of the impact). Do not use a transmitter that has seals that have been compromised.
Inspect the membrane switch for the Graph and Verify Leads controls. If
the membrane is cracked or damaged, do not use the transmitter.
Inspect the leadwire connections for corroded or bent connector pins. Do not
use a transmitter with bad leadwire connectors.
Inspect the leadwires for cracks or other damage. Replace leadwires that are
cracked, damaged, or no longer flexible.
Open battery compartment and inspect the battery contacts. Clean them if
they are dirty or corroded.
The battery compartment is not sealed and may be exposed to moisture. If
there are any visible signs of moisture within the battery, return for service.
Inspect the dust covers before each use to verify that they are securely
attached.
If a transmitter or leadwires fail any of the above inspections, immediately service or replace it.

i. If the difference is less than or equal to ±130 Hz, no adjustment is
required as the transmitter is within specifications. If the difference is greater, proceed to Adjust T14 transmitter frequency.
NOTE
If the difference is more that ±1400 Hz from the target frequency, take the transmitter out of service and contact GE.
WARNING
The T14 transmitter cannot be adjusted more that 1400 Hz over the lifetime of adjustments. Refer to the previously recorded adjustments to ensure that the overall total of adjustments is not or will not be more than 1400 Hz. If it greater than or equal to 1400 Hz take the T14 transmitter out of service and contact GE.
NOTE
This procedure applies to the T14 transmitters. If the ApexPro or ApexPro CH transmitter frequency needs to be adjusted, send the unit to GE for service.

System troubleshooting

RF drop-out determination

Turn on drop-out flags on the CIC Pro to check the color of any drop-out on the patient signal lead waveform at the CIC Pro patient view.
1. From the Main CIC Pro screen, select the Setup CIC button.
2. Select the Service Password tab.
3. Type the passwor d mms_com and then select OK. A Command prompt window
is displayed.
4. Type setflags<Space>-mark<Space>all and press Enter on the keyboard to
turn on drop-out flags.
If the color is yellow, suspect RF drop-out on the transmitter, the antenna
system or the receiver system.
If the color is light blue or dark blue, suspect a network issue, not an RF-
related drop-out.
If it is another color, refer to the CIC Pro Service Manual provided with your
system for the cause since this indicates that it is not RF drop-out.
5. Type setflags<Space>-mark<Space>off and press Enter on the keyboard to
turn off drop-out flags.
Troubleshooting
6. Close the Command prompt window and the CIC Setup window.

Yellow drop-out condition

Determine the source of the problem
1. Verify the patient/transmitter is in the coverage area. If not, the system is not at fault.
2. On the CIC Pro:
Ensure that you are viewing all leads for the patient/transmitter. If the status is Leads Fail, correct the system. Refer to the operator’s manual
provided with your system.
NOTE
If a shorted-leadwire set is used, an Asystole alarm will sound if the transmitter is admitted. This alarm can be silenced by turning off all alarms for this admitted bed.
3. Check the transmitter battery status. If the status is Low Batt, correct the condition by replacing the batteries with new ones.
NOTE
If needed, refer to the appropriate ApexPro T elemetry Service Manual or the operator’s manual provided with your system.

NOTE
Once you select this option, you have five minutes to enter the duplicate TTX numbers. If that is not enough time, simply select this option again and continue entering TTX numbers.
5. At the CIC Pro center, admit a duplicate TTX four times. You should have the same TTX admitted five times. This will ensure that the TTX is admitted to at least two different receiver cards.
6. Type setflags<Space>-dup<Space>off and press Enter on the keyboard when you want to turn off duplicate TTX.
7. Close the Command prompt window and the CIC Setup window.
If drop-out continues on both receivers, suspect the transmitter. Swap the
transmitter with a known good transmitter. Drop-out should go away.
If drop-out is on one receiver and not the other, See Troubleshoot the
receiver on page 5-6.
If drop-out is on one receiver and not on the other, use the ApexPro Telemetry Server Service Manual provided with your system to complete the following steps.
1. Isolate which receiver subsystem is attached to the CIC Pro center you’re viewing by using the service diagnostic tool PTSCONFIG at the CIC Pro center/ telemetry server and the command “blink patient unit|bed*” in order to associate a care unit/bed number to a receiver in a given rack.
5-6 ApexPro™ 2001989-351A

2. Once the receiver subsystem is known, check all LEDs for proper operation. Verify their status with the Receiver Subsystem LED status chart on page 5-13.
3. Swap the suspected receiver with a known good receiver card. Drop-out should go away.
If drop-out does not go away, suspect an antenna coverage problem. See Antenna
system troubleshooting on page 5-7.

Quick antenna system checks

1. Check all antennas: a. Check to see if each antenna’s LED is illuminated. b. If any antenna’s LED is not illuminated, make sure its power supply is
powered. Apply power to the antenna power supply if necessary. c. Make sure all cables are properly connected. d. Replace the power supply if necessary.

With transmitter powered, press Graph and Verify Leads buttons at the same time. The Pause Alarm LED will begin to blink. This mode will remain active for 5 minutes (default time) or until transmitter is powered down or is taken off Pause Alarm mode, whichever occurs first. (After 5 minutes the RF will shut off.)
15. Place the transmitter in the same position on the spectrum analyzer as in step 9.
16. Turn on a marker and place it on the peak of the signal.
17. Turn on averaging to average over 10 samples. a. Press TRACE. b. Press F1 - TRACE MODE. c. Select AVERAGE. d. Press ENTER.
18. Move away from the analyzer. Your body will affect the measurement, so make sure your hands are at least 3 feet away from the analyzer, antenna, and transmitter.
19. Wait for 10 seconds and then record the peak of the signal.
NOTE
When measuring the signal, ensure that the transmitter is still in Pause Alarm mode by verifying that the no alarm LED on the front of the transmitter is blinking.
20. Repeat steps 5 through 19 for all transmitters to be tested. We recommend the following table for data collection:

Acceptance criteria
The transmitter's carrier level should be 30 dB or more below the transmitter’s modulated output. For example, if a transmitter’s modulated output is -55 dB, its carrier level should be -85 dB or lower. If the carrier level is higher, the transmitter needs repair.

General fault isolation

Visual inspection
A thorough visual inspection of the equipment can save time. Small things— disconnected cables, foreign debris on circuit boards, missing hardware, loose components—can frequently cause symptoms and equipment failures that may appear to be unrelated and difficult to track.
The following steps might seem trivial but it is highly recommended that they be performed to remove these “simple” failures as causes of problems.
NOTE
Notify the staff and move any admitted patients off the receiver system or provide for alternate monitoring before removing power from it.
Set the ON/OFF switch to the OFF position and disconnec t the Receiver System
from its power source.
Perform an internal visual inspection of the components.See Replaceable parts
on page 6-1.
Take the time to make all the recommended visual checks (refer to the visual inspection table below) before starting any detailed troubleshooting procedures.
Area Look for the following problems: I/O Connectors and
Interface Cables
Internal Harnesses and Cables
Circuit Boards Moisture, dust, or debris (top and bottom)
Ground Wires/Wiring Loose wires or ground strap connections
Mounting Hardware Loose or missing screws or other hardware, especially fasteners used as connections to ground
Fraying or other damage Bent prongs or pins Cracked housing Loose screws in plugs Excessive cable tension or wear Secure mounting hardware
Excessive tension or wear Loose connection Strain reliefs out of place
Loose or missing components Burn damage or smell of over-heated components Socketed components not firmly seated PCB not seated properly in edge connectors Solder problems: cracks, splashes on board, incomplete feedthrough, prior modifications or repairs
Faulty wiring Wires pinched or in vulnerable position
planes on PCBs
Receiver System mounted loosely or near vibration
Power Source Faulty wiring, especially AC outlet
Circuit not dedicated to system (Power source problems can cause static discharge, resetting problems, and noise.)
