2 Principles

2.1 System Operating Principle

TMS60 is a digital telemetry monitoring system consisting of the transmitter (TD60), the
receiver (RC60), the antenna array. The transmitter sends the patient’s physiological
information to the receiver, which then transmits the information to the Central
Monitoring System (CMS) for analysis, displaying, storage and printing. The transmitter is
attached to the patient, whereas the receiver is used together with the CMS. TMS60
telemetry monitoring system is intended to monitor and display a fixed set of parameters
including ECG, Resp, SpO
module, SpO

2.2.3 Receiver

2.2.3.1 Principle Diagram

Figure 2-3 Receiver Principle Diagram

The receiver comprises the AC/DC power source, power adapter board, amplifying and
branching module, 4-channel receiver, LED board, main control board and network
interface board.

BeneVision TMS60 Service Manual 2-3

2.2.3.2 AC/DC Source

The AC/DC source is to convert the externally inputted AC source into a 9V DC by means
of isolation. The inputted AC voltage range is from 90V to 264V, and the outputted
voltage/current is 9V/6.5A.

2.2.3.3 Power Adapter Board

The power adapter board is to drop the 9V DC coming from the AC/DC source to a 5V DC
and then output it with the 9V DC.

2.2.3.4 Amplifying and Branching Module

The amplifying and branching module is to amplify, filter and branch RF signals. The
module allows two amplifying, filtering & branching circuits with circuit parameters in full
symmetry. Each circuit amplifies, filters and branches the RF signals received by its
corresponding antenna and then outputs 4 channels of RF signals. Therefore, there are a
total of 8 channels of RF signals, which are then sent to the 4-channel receiver for
processing. The 9V DC linearly drops down to an 8V DC, which then goes to the
amplifying and branching module. The antenna array is shared by all receiving modules.
Therefore, in order to compensate for the branching attenuation of the signal, a LNA (low
noise amplification) is added before the branch divider. Besides, to avoid that the LNA is
blocked by strong out-band signal interference, filtering circuits shall be added in front of
and behind the LNA.

2.2.3.5 4-Channel Receiver

The 4-channel receiver divides the two channels of antenna signals coming from the
amplifying and branching module into four channels of RF signals through the 4-channel
branch divider. The MCU of the 4-channel receiving board will estimate the received
signal strength (RSSI) and then select the corresponding antenna signals through the
antenna switch. The selected signals will be respectively sent to the receiving modules for
filtering, amplifying, mixing, filtering and demodulating. The demodulated 4-channel
analog signals will then be sent to the MCU system for clock and data regenerating. The
regenerated data is packed by CPU and then delivered via the asynchronous serial port to
the main control board for processing. The 9V DC linearly drops down to an 8V DC, which
is then stabilized into a 5V and a 3.5 V supplying power for the 4-channel receiver.

2.2.3.6 Main Control Board

After receiving the data coming from the 4-channel receiving board, the main control
board will pack them and then delivers them to theCMS through the Ethernet. The
speaker of the main control board will give a short beep when the initialization is over,
and will beep continuously when an initialization failure or a hardware fault occurs.

2-4 BeneVision TMS60 Service Manual

2.2.3.7 LED Board

The LED board has two green LEDs, respectively indicating the power status and the
communication status of the receiving module.

2.2.3.8 Network Interface Board

The interface between the main control board and Ethernet consists of the network
isolating transformer and interface connector.

2.2.4 Central Monitoring System (CMS)

BeneVision Central Monitoring System comprises powerful system software and
high-performance computer components. It constructs a monitoring network by
connecting monitors and telemetry transmitters. By collecting, processing, analysing and
outputting the information coming from monitors and telemetry transmitters, the CMS
can achieve centralized monitoring over multiple patients so as to greatly promote the
efficiency and quality of the monitoring work.

The CMS is capable of connecting up to 32 telemetry transmitters.

2.2.5 Central Charger

The central charger inner structure consists of three boards, as shown in Figure 2-4:

Measurement accuracy verification:
The accuracy of Masimo and Nonin SpO2 modules has been verified in human
experiments by comparing with arterial blood sample reference measured with a
CO-oximeter. Pulse oximeter measurements are statistically distributed and about
two-thirds of the measurements are expected to come within the specified accuracy
range compared to CO-oximeter measurements.

NOTE

 A functional tester cannot be used to assess the accuracy of a pulse

oximeter monitor. However, it can be used to demonstrate that a particular
pulse oximeter monitor reproduces a calibration curve that has been
independently demonstrated to fulfill a particular accuracy specification.

1. Connect a receiver to the antenna array.

2. Turn on the telemetry monitoring system and the CMS. Ensure that the

telemetry monitoring system works normally.

3. Remove the battery of interference transmitter; make sure its RSSI in the

telemetry window of the CMS is not higher than 130 (-105dBm). If the RSSI is
higher than 130 (-105dBm), use the CMS configuration tool to scan all of the
frequencies, and choose a frequency, of which the signal is lower than

-105dBm, and program it to the interference transmitter.

A Electrical Safety Inspection

The following electrical safety tests are recommended as part of a comprehensive
preventive maintenance program. They are a proven means of detecting abnormalities
that, if undetected, could prove dangerous to either the patient or the operator.
Additional tests may be required according to local regulations.

All tests can be performed using commercially available safety analyzer test equipment.
These procedures assume the use of a 601PROXL International Safety Analyzer or
equivalent safety analyzer. Other popular testers complying with IEC 60601-1 used in
Europe, such as Fluke, Metron, or Gerb, may require modifications to the procedure.
Please follow the instructions of the analyzer manufacturer.

The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step if an approved agency status is to be maintained. The
safety analyzer also proves to be an excellent troubleshooting tool to detect
abnormalities of line voltage and grounding, as well as total current loads.
