Telemetry
Uses 1.4 Ghz protected WMTS(Wireless Medical Telemetry Service) freq band
Tele and wireless bedsides can use same infrastructure CWI (common Wireless Infrastructure).
Bidirectional Uses Smart Hopping. Make sure you mark that instead of 802.11
If a frequency is interference occursthe tele signal hops to afreg /time slot for better performance.
ITS Transceivers TRX -- ecg only smaller and lighter ( No SPO2 hanging off the side.
TRX+ -- ECG + SPO2 or ECG upgradable to
SPo2
Telemetry does all calcs at the PIIC.
SpO2 –
Transceiver sounds:
New device-- hasn’t been configured yet(Repeating double beeps
and all LED’s flashing.
Self test pass one beep fail two beeps
Not connected to PIIC = double beeps every 5 seconds. Single beep
when check button pressed means in contact with PIIC. Doubles
mean not in contact.
Find device-European ambulance tone
Spot check can be initiated at the PIIC or when the sensor is
inserted. Transmitter emits a pulse detection tone during the
measurement
The transmitter beeps to indicate if the measurement was successful
or not. One beep means passed. 2 means failed
If Pulse is detected single beep for each beat while measuring SpO2

Standby:
Standby Duration times are infinite to 10 minuts. Clinicians put the device in standby from the PIIC for however long they believe the patient will be out of range. Appr time till resume
shows in the standby window. Unit uses the most battery juice when coming out of standby looking for an AP.

Likely Problems for the TelePak:
Poor ECG quality when used in showere due to water collecting in connector. Should encourage use of the Pouch
with protective flap. The transceiver won’t be damaged but the leadset will have to be dried out.
Likely Problems for AP:
Check for active connection between AP and APC:
Go into Philips wizard: and go to status tab
If screen is displayed, the AP is communicating with the APC
Note that a lot of info is on this screen:

IP address

Channels

Firmware Rev

LED status(available for 1.4 core AP. Not for the standard
AP) Keep pressing F5(refresh) to see if network and Radio
LED’s are OK. Screen doesn’t refresh on its own.

Remote antenna Status

Dip Switch setting

Insufficient spectrum status
Power/Sync flashing green-Loss of remote sync unit
Flashing Red- Loss of sync unit connected to this AP
AP Self-Test Passed but unregistered
Radio LED ON=Amber
Ntwk LED on-Amber
Power/SyncLED on – Amber
Other LED on’s indicate AP failure&need to replace
FDX(Full Duplex) off= Device is operatin in half duplex: DIP switch 4 set improperly
100M OFF AP operating at 10 Mbps again DIP 4 set improperly & connected to a switch configured for 10Mbps/Half
Duplex.
Link OFF=Problem with the network connection.
Act-Activity Off continuously : indicates no communication to or from the AP over wired link.
Likely Problems for APC:
Losing it’s configuration
Caused by how the “Master” APC manages transferring the
configuration files to the “Slave” APCs. If the installation
instructions are not followed precisely, the configuration will not be
transferred to ehe “Slave” and if the “slave” ever becomes the
“Master” the configuration will appear to be “lost”. Always run the
AP/APC upgrader Tool to make certain the configuration is
transferred properly!!!
Remember that the order things are done, does matter
Transceiver Tool Connecting to a Transceiver
1.
Connect the service cable between the service PC
and transceiver.
2.
Start the Application.
3.
Click on :Connect
4.
Insert batteries into the transceiver
5.
The tool updates with status information
Coverage Assessment Tool:
Transceiver can be programmed to use the LED’s on it
to report received signal strength and it will start beeping
when the signal strength drops below the “Weak signal”
limit of -75dBm

Any IIT wireless bedside will report the received
signal strength in service mode, in the instrument
Telemetry Diagnostic screen.

Any MRx defibrillator will report the received
signal strength in the “Network Settings” screen

Note: the access point and the transceiver both
broadcast at the same signal strength so the
received signal strength reported by the
transceiver will accurately reflect the signal
strength received by the access point.

The body will impact strength(transmitted and
received) so it should be worn the way a patient
wears it. Use a pouch and adjust so you can see
the LED’s.

If you hold it, hold close to the body and away
from ECG leadset. Your hand will cause a lot of
RF Absorption and result in a poor
measurement.
2 operating modes; Philips recommends the average.
RSSI(Received Signal Strength Indicator) mode. Can be
changed by pressing the “Telemetry button”.
Average RSSI mode

EASI LED is “on”

Provides the average RSSI over the last
3 seconds
Point RSSI Mode

EASI LED is off

Samples and reports RSSI every 25 ms
Battery on Telepak shows how strong signal is. There is
no audio feedback unless there is no signal which is the
double beep.
All LED’s on = >49dBm good signal
Botom 3 on = -50 to -69 dBM Good Signal
Bottom 2 on = -70 to -75 dBM Marginal to weak
Bottom 1 = <-75 dBm Weak signal
No lights = No connection to AP and Double beep.
At the bedside monitor, go into service Mode

Syck Network Design
If the wireless networkneedsmorethan onesync Unit a Synck network design isrequired.
In these situations ther is a singleMaster sync uit and one or more to talk to.
4 synces can be daisy chained together or configured in star topology.
