Description
The receiver has a modular structure and comprises the following boards:
• Mainboard
• Display module
• RF module
• Monitor module (only EM 500 G2)
The display, RF and monitor modules are each connected to the mainboard via a
15-pin ribbon connection. The following sections explain the principal functions.
3.1
Mainboard
The mainboard is a single-sided PCB assembly. It is manually screwed to the side
walls, the front and the back panel wall and the RF module. The mainboard
performs the following functions:
• Conditioning of power supply
• Conditioning of AF signals
• Provision of power supply to additional modules
• Control of own functions and the RF and monitor module via the
microprocessor
3.1.1 Processing the diversity signal
The signal from the RF module with the highest field strength is switched by the
U50 or U51 diversity switches and reaches four signal conditioning blocks that are
connected in parallel.
3.1.2 U52 squelch switch with AF conditioning
If the squelch threshold you set is exceeded, U1 uses U52 to switch the AF signal
and activates the AF high pass filter with U75-1, the AF low pass filter with U75-2
and U76-1, the HDX expander with U100 and the AF stages U101-1, U101-2 and
U76-2.
With EM 500 G2 the AF stages U101-1 and U101-2 are used via analog switch U300
as LOW-CUT filters with a threshold frequency of 200Hz and with U301 as
HI-BOOST filters with an increase of approx. 5dB at 10kHz. Control is via U1,
Q300-1 and Q300-2.
The peak detector is connected to the level indicator behind U76-1 with U100 operational amplifiers (U100-2 and U100-1) whose output signal DEV_L is available to
microprocessor U1 for evaluation.
The two AF signals AF_0 (U76-2) and AF_180 (U101-2) both reach a divider
resistance chain at the inputs of analog switches U175 and U176, via which eight
AF signal switching stages are set by the user. The structure is strictly balanced and
is laid behind the active stages to guarantee full signal to noise ratio even if the
AF signal is weakened by approx. 40dB. From the two outputs, the AF signal then
reaches across various components to protect from ESD parasitic signals and
phantom voltage at AF sockets P175 and J175.

3.1.3 Evaluation of the TX battery signal
The battery telegram sent by the transmitter reaches the U60-2 trigger stage, at
whose output appropriate square wave signals are available for evaluation by U1,
via the 4Hz low pass filter with U60-1.
3.1.4 Evaluation of the pilot signal
The 32.768kHz pilot signal sent by the transmitter is filtered from the signal mix
by the active crystal filter with Q95, Y95 and U95-1, rectified via the D95 diode and
made available for evaluation by U1 via trigger stage U96-1.
3.1.5 Functions of microprocessor U1
The receiver is controlled by the 8-bit U1 microprocessor, which contains in its flash
memory the control program and uses a sub-area as an EEPROM for saving data
even in the event of power failure. The microprocessor uses a 4MHz crystal to
generate both its own internal 8MHz cycle and the reference frequency for the
RF module PLL. It processes the signals already described in line with the program
specifications and the user specifications that can be set on an individual basis via
a menu.
3.1.6 Service interface (RJ45 socket)
The service interface “DATA“ with RS485 protocol, located on the back panel of the
unit, fulfills an important function. The RJ45 socket allows the relevant EEPROM parameters on the RF module and the simulated EEPROM to be read out and modified
in the microprocessor. This interface also enables a software update as part of the
hardware options. For example, the RJ45 socket enables you to read unit data and
write-in after replacing a board. The necessary service software is
available for download free of charge on our Internet homepage:

3.2
RF module
The RF module is a single-sided PCB assembly that is fixed to the back panel via the
BNC input sockets and to the mainboard via a sheet metal brace. The RF module
performs RF conditioning until demodulation of the IF signal. The module is connected to the mainboard via a 15-pin ribbon connection; the following functions are
performed by the plug-in connection:
•
•
•
•
•
Incoming power supply of 5V DC from the mainboard.
Incoming system cycle (4MHz) from mainboard microprocessor.
2 x outgoing AF voltage to mainboard
2 x RSSI voltage to mainboard.
Communication between the mainboard microprocessor and
the EEPROM or the PLL for the RF module.

3.2.1 RF module shielded compartments
The shielded compartments on the RF module perform the following functions:
• The two compartments between the BNC sockets contain the second mixer,
the 10.7MHz limiting amplifier and the FM demodulator.
• The compartment directly behind the BNC socket contains RF conditioning
up to an including the SAW filter for the first IF.
• The middle compartment performs frequency conditioning for the first
oscillator with VCO, buffer and PLL for both diversity channels.
The input filters are assembled outside the shielded compartments to ensure that
parasitic LO frequency currents cannot be coupled directly to the RF input. The input filters are relatively complex owing to the integrated IF and LO cases,
but nevertheless do not require alignment.
3.2.2 Alignment of the RF module
The only components still to be adjusted are
• C540 for alignment of VCO voltage at center frequency,
• C330 for setting the LO2 crystal oscillator,
• The L310 and L410 discriminator coils, and
• The two level adjusters for the AF outputs.
For communication with the processor on the mainboard, the RF module contains
the U700 EEPROM, in which the relevant frequency range data, the RSSI table and
other status data are stored. Communication is processed via the same bus used by
the microprocessor to communicate with the PLL U500 (frequency setting).
3.3
Display module
The display module for the status displays is connected to the mainboard via a
15-pin ribbon connection.
3.4
Monitor module (only EM 500 G2)
The monitor module (MOD.A020) is a single-sided PCB assembly and is connected
to the mainboard via a 15-pin plug-in connector. The monitor module PCB has a jack
socket for connecting headphones, and an appropriate volume control. The monitor
module also has a complete U1 and U2 amplifier for each AF phase; the volume can
be adjusted via R1.
The monitor module is primarily intended for stereo operation, but in phase configuration is possible for mono operation. If you want to minimize the volume differences in mono operation between the left and right channel (this may occur as a
result of the tolerances of R1), you must close the M1 solder bridge.
You must not close the M1 solder bridge if you are using the monitor
module in stereo mode.

Reading out/changing unit data via the “DATA“ service interface
5.4.1 Overview
You can read out and change unit data via the integrated “DATA“ service interface.
For example, Sennheiser's service software helps you with the following functions:
•
•
•
•
Reading out the current software version and, if necessary, initiating a software update.
Commissioning the receiver following replacement of hardware (e.g. when a board is changed).
Changing the current frequency table.
Changing/resetting the receiver factory settings.
5.4.2 Required hardware
You need the Sennheiser service set for unit data read-in and read-out.
The service set contains for portable ew G2 units
• an infrared adapter for reading out/in data from portable units (e. g. SK 100),
for rack-mount ew G2 units
• an RS232/RS485 converter,
• an RS232 cable to connect the PC and the converter.
• an RS485 cable to connect the receiver and the converter.
You can order the service set directly from Sennheiser:
service set for software ew G2, ID no. 094739, price group 161
5.4.3 Required software
The service software is available for download free of charge on our Internet homepage:
www.sennheise.com > Service & Distributors > Service Documentation > Download
The minimum operating system requirement to run the software is Microsoft® Windows 95™ ,
and a free COM port (RS232) is also required.
5.4.4 Information about the service software
A user guide for the service software is available in PDF format. It contains information about how to
commission the service set, how to install the service software and how to read in/out unit data.
Please find more informations in the instructions for use of the ew G2 service software. Once the installation of
the software is complete you can find this help file in the Windows menu [Start].

5.4.5 Commissioning after board replacement
After you have fitted a new board to the unit, you must use the service software to write the data to the unit
again (e.g. new frequency table).
Requirements
1. You have replaced a faulty board (e.g. receiver RF board),
2. You have connected the receiver via the DC IN an +12 V DC socket.
3. You have connected the unit to the COM port on the PC via the “DATA“ service interface.
4. You have installed the service software and launched it.
5. You have switched on the unit.
Writing unit data
Perform the following steps:
1. Click the button [Auto Detect].
Result: Your connected unit is detected.
2. Click the button [EXECUTE ALL] in the Info tab.
Result: All unit data is read out. If all the data are successfully read out, the message “Success“ appears.
Note: If you perform individual actions in the “Info“ or “Service“ tabs, you must subsequently return the
unit to operational status. Click on [Close Device] once the actions have been completed to do this.
3. Switch to the “Service“ tab.
4. Click the button [EXECUTE ALL].
Result: The new unit data will be written. If all the data are successfully written, the message "Success"
appears.
Result
You have successfully written the new data to the unit. These new data now correspond to the
new factory settings for your unit. Your can find these data in “D:\Sennheiser\ew G2 service package“ in the
files “Defaults.dat“ and “FreqTable.dat“ or alternatively “FreqTableIEM.dat“.
