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. 7 EM 100 G2, EM 300 G2, EM 500 G2 08/2004 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: www.sennheiser.com > Service & Distributors > Service Documentation > Download 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. EM 100 G2, EM 300 G2, EM 500 G2 08/2004 8/32 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. 9 EM 100 G2, EM 300 G2, EM 500 G2 08/2004 002 003 002 EM 100 G2, EM 300 G2, EM 500 G2 08/2004 004 005 019 012 013 013 003 018 017 018 018 incl.: 017 018 006* * Pos. 006 Exploded view: EM 100 G2 009 020 007 4.1 004 011 016 016 020 Exploded view 005 008 001 4 10/32 002 11/32 003 002 004 005 012 008 010 004 005 016 001 016 013 020 020 009 019 011 012 013 007 014 003 018 015 017 incl.: 017 018 006* * Pos. 006 4.2 Exploded view: EM 300 G2, EM 500 G2 EM 100 G2, EM 300 G2, EM 500 G2 08/2004 Pos Bezeichnung 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 Casing Lens screw Holder Lens screw Spring washer Front module with display Rear panel Label PCB mainboard PCB monitoring module (EM 500 G2 only) PCB RF module Lens screw Flat cable, 15-pin Flat cable, 30-pin Knob (EM 500 G2 only) Socket BNC 50R Key cap ON/POWER Key cap UP/DOWN/SET Built-in plug XLR3M Lens screw EM 100 G2, EM 300 G2, EM 500 G2 08/2004 12/32 5 Test and alignment instructions 5.1 Measuring and test equipment • • • • • • 1 Spectrum analyzer up to at least 1.5GHz 1 RF signal generator 1 AF level measuring device 1 Oscilloscope 1 Multimeter 1 Laboratory power supply unit 5.2 Measuring set-up + DC IN EM x00 G2 DATA Laboratory power supply unit AF OUT RF IN 230.00 MHz Oscilloscope AF level measuring device RF signal generator Other measuring equipment Spectrum analyzer 13/32 Multimeter EM 100 G2, EM 300 G2, EM 500 G2 08/2004 5.3 Test table Sequence Type of measure- Signal input ment/adjustment Settings Measuring point/test point Required value Remarks 1 Visual inspection 1.1 Jack socket PHONES – (only EM 500 G2) – – – Contacts are not twisted, no hairline cracks at the solder points, no mechanical damage 1.2 Volume control (only EM 500 G2) – – – – See 1.1 1.3 – 왖왔, SET, POWER/ON buttons – – – See 1.1 1.4 DC socket, DC IN – – – – See 1.1 1.5 XLR socket – – – – See 1.1 1.6 Jack socket – – – – See 1.1 1.7 RJ45 DATA socket – – – – See 1.1 1.8 BNC sockets – – – – See 1.1 1.9 Monitoring of all display elements +12VDC at DC socket "POWER" = ON – – Monitoring of all display segments 1.10 Monitoring of the il- See 1.9 luminated 왖왔, SET, ON buttons (not EM 100 G2) See 1.9 – – – 2 Mainboard: current and voltage measurement 2.1 Standby See 1.9 "POWER" = Off "VOL" = min.
