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)

Equipment Overview

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
2-4ApexPro™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.

While in normal application mode, pressing and releasing the Verify Leads button
causes the LEDs to light up for 1 minute if their corresponding lead is good. Pressing
and releasing the Graph button causes either a save or a manual graph at the CIC Pro
center.
Pressing both the Verify Leads and the Graph buttons together causes an alarm
pause condition for the programmed amount of time (typically 5 minutes) or until the
alarm pause action is initiated again. When the transmitter is in alarm pause, the
corresponding LED flashes once every second at a 1/8th duty cycle.
Upon any activation (Verify Leads, Graph, or Alarm Pause) the top row of LEDs
flash twice. All these functions are disabled in service mode.

Equipment Overview
When the battery voltage drops below 1.9 volts for ApexPro,1.6 volts for ApexPro
CH or 1.73 volts for the T14, the Change Battery LED flashes once every second at
a 1/8 duty cycle.
RF
The RF output is transmitted through one of the shield wires on the multi-link cables.
The carrier frequency can be programmed to any frequency within the allowable
band.
DINAMAP PRO series monitors
The DINAMAP PRO 100, 200, 300, and 400 series monitors can be connected to the
transmitter using the DinaLink™ serial cable to monitor SpO2, NBP , and temperature.
Parameter data from the PRO 100–400 series monitors is displayed, trended, and
stored at the CIC Pro center.
The DinaLink interface cable assembly consists of a monitor adapter cable, the
DinaLink adapter, and an interconnection cable. It connects the transmitter to the
PRO 100–400 series monitors and provides electrical isolation. The interconnect
cable connects to either of the optional interface ports on the transmitter

SpO2 oximeter modules
The oximeter is an optional module that, when connected to the transmitter, allows
telemetry monitoring of a patient’s pulse oximetry data. The oximeter must be
connected to an transmitter in order to convey SpO2 data to the CIC Pro center. Only
digital data is available; no waveforms are generated or transmitted .

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:
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.
2001989-351AApexPro™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.

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.
1Center conductor — The center-most feature of coaxial cable. It consists of solid copper
or copper-clad aluminum wire.
2Dielectric — 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
3-2ApexPro™2001989-351A
also be evenly spaced solid polyethylene discs.
200A
Page 43
Strippers and crimpers
Installation and configuration
3Outer conductor or foil — Either solid aluminum tube or an aluminum foil wrap. The cable
size is usually derived from its outside diameter.
4Braid — Interwoven strands of aluminum or copper mesh. It extends the conductivity of
the outer conductor to the sleeve of the connector.
5Jacket — 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.

Install antennas
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.

Due to the fact that frequency drift occurs even without power applied, the cailbration
schedule should take into account the date the equipment was last calibrated,
including equipment in storage locations and spares.
Before installation, determine and record the date of initial factory calibration of
transmitters and receivers from the removable calibration sticker that ships on these
devices. If the installation is not within 30 months of the date shown on the
manufacturer calibration sticker, calibrate before installation. See Calibration on page
4-10.
The mounting options for the ApexPro Telemetry System Receiver System are:
Standard tabletop mount (four rubber feet)
Optional rack mount for standard 19 inch network rack system with a 4U panel
Mount the receiver system securely and away from vibration.
Vibration may cause patient waveform dropout at the CIC.
NOTE
If using rack mount, route all cables to the hinge side so the receivers are
accessible for service. A right angle F-connector may be helpful for the
coaxial cable.

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

ApexPro CH Telemetry Tune-Up
Introduction
To make sure the ApexPro CH antenna infrastructure remains in proper operational
and functional order, a proper maintenance schedule must be observed.
RF environment changes
Changes in the RF environment could adversely affect the output of the original
design of the antenna infrastructure.
Schedule
WARNING
LOSS OF DATA—The manufacturer requires that calibration be
performed by service personnel as follows:
For 1395-1400 MHz systems calibrate the following every 2 years:
T14 transmitter
RIM 1400
Receiver subsystem
Due to the fact that frequency drift occurs even without power applied, the cailbration
schedule should take into account the date the equipment was last calibrated,
including equipment in storage locations and spares.
Determine and record the date of initial factory calibration of transmitters and
receivers from the removable calibration sticker that ships on these devices. Calibrate
within 30 months of the date shown on the manufacturer calibration sticker or 24
months after installation, whichever occurs first, and every 24 months thereafter.
Additionally, the manufacturer recommends that service personnel perform the
following maintenance procedures upon installation of antenna infrastructure, prior to
every antenna expansion, and every 12 months thereafter.

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.

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.
