The me-d200/d350 is housed in a rugged cast-aluminium box sealed to IEC 529 (IP54) making it suitable for a wide range of mobile and fi xed applications. All me-d200 modem units meet the essential requirements of the relevant European directives and all me-d350 modems meet relevant US FCC and Canadian regulations. In order to maintain this compliance the installation and safety information must be adhered to at all times. The me-d200/d350 modem must only be installed where unintentional contact cannot be made. The surface of the device may be hot to touch under certain transmit conditions. A warning label is permanently displayed as part of the equipment rating label af fi xed to the lid. The me-d200/d350 is not designed for permanent transmis-sion. If prolonged transmission periods are used, the unit will become hot and will require an additional heatsink to be fi tted. When fi tting the me-d200/d350 into a fi xed installation, care must be taken in the routing of all cabling such that the insulation cannot become damaged.The recommended supply sources for use with the me-d200/d350 are a standard 12V supply, but is capable of operating in the range (9V - 18V). ●●● Preparing for useUnpacking and inspectionUnpack the modem and check that you have received the following items: me-d200 or d350 TransceiverUser Guide (this document) me-d200 diagramme-d350 diagram:If any of these items are missing, please contact your supplier.●● e11 034663 35 4 5 Description of modemThe me-d200/d350 is a network free, point to point data radio that offers great fl exibility in varied applications where wireless data or voice communication is needed. It can be used as a “dumb” radio, with no internal module fi tted, to allow users to facilitate the use of their own modem and protocol. Internal link changes enable the input to be set for TTL levels so allowing POCSAG for example. In this scenario, the radio is completely transparent and simply needs the correct signal level inputs (see pin out details), and use of separate control lines (PTT etc) or serial commands.The me-d200/d350 can also be fi tted with either a Bell 202,V.23 module, a FFSK module (up to 4800 baud rate) or a GMSK module (up to 9600 baud rate). These allow communication with a pc via hyper terminal and other emulation packages. For further information on these options, including pin outs, please refer to the separate Module Manual available on the Mobile Expertise web site.The me-d200/d350 also operates as a standard radio with microphone input and speaker output, in this mode the radio has the following associated features, these include CTCSS/DCS, busy channel lockout and scan Features Compact and rugged die cast boxResistant to dirt, dust and water ingress (IP54 rated)Network free, point to point communication1/5 watt programmable output powerSynthesised operation with 16 channel capabilityCTCSS & DCS encode and decodeprogrammable 12.5 / 25kHz channel spacingExternal modem / Dire…

D350 THEORY OF OPERATION Page 1 of 8 D350 THEORY OF OPERATION D200 THEORY OF OPERATION Page 2 of 8 1 INTRODUCTION The VHF and UHF radios comprise of two PCBs, the RF and the digital PCB, connected via an 18-pin female and male connector. The digital board, which controls the radio functions and data inputs/outputs, is interfaced with external data equipment through the 15-pin d-type sub female (DB-15) connector. 2 DIGITAL CIRCUITS The Digital circuit contains the CPU, the channel select switch, and associated digital circuits. 2.1 TX-SIGNAL CIRCUIT There are different signal paths for the TX signal depending on user requirements Data Filter (pin 1) The data signal from Pin 1 of DB-15 connector (CON401) goes through IC406-C. The signal is amplified by IC404-C and then its amplitude is limited by IC404-D. It is filtered by an 8th order low pass filter (IC405) to reduce the bandwidth. The first two stages of the 8th order LPF consist of a Gaussian filter for the improvement of ramp function response and the last two stages use a Butterworth filter for attenuation at higher frequencies. The output of the LPF is then fed to the RF board for TX modulation External modulation path with no data filter (pin 1) This route is programmable and bypasses the data filter. It routed via an ac- coupled buffer, then directly to the RF. POCSAG route (pin 1) This route uses the same circuitry as 2.1.2, but with modifications to make it compatible with TTL levels for POCSAG signals (TTL levels) DC coupled signal with no filtering (pin 1) Link(LK430) changes route the signal directly to a voltage limiting circuit (diode and resistor added) then directly to the RF stage Voice (pin 7) The audio signal, from Pin 7 is switched by IC409, through the 300Hz High pass filter, IC408, (removal of voice components below 300Hz allows SAT to added) to the audio filter with pre-emphasis. The signal is then fed to the data filter, IC405 as described in 1.1.1 above. The output of the LPF is fed to the RF board for modulation. Module option board route (pin 10) From pin 10 the signal (RS232) is routed directly to the module option board, for processing, then to the MOD input of the RF. D350 THEORY OF OPERATION Page 3 of 8 2.2 RX-SIGNAL CIRCUIT The Rx-signal circuit is split into several routes Data output (pin 2) Data signals are switched through IC407-C by a ‘busy’ signal, which is activated when the radio receives a valid RF signal. It passes through a filter and amplitude level adjustment (IC416 A and B) to pin 2 of the DB-15 connector (CON401). The data route can be altered uses the available links in the data decoder Option Board Module Data Route (pin 11) The option board module signal is routed via IC407C and the level shifter IC416C, to the option board. For GMSK the dc level needs to be within specified limits for the GMSK chip to demodulate the signal. The decoded signal from the option board is routed directly to pin 11 of the DB-15 connector. For FFSK or AFSK (Bell 202/V23) the signals can include SAT tones, so the signal is also routed via IC409 to the decode circuit as described below. Speech (pin 9) Audio voice signals are switched through the analogue switch (IC409) to the 300Hz High pass filter (IC408) to eliminate the sub-audible tones (CTCSS/DCS). The output of the HPF is switched through IC418 (disabled if data is enabled) and IC406-A. The voice signal is then de-emphasized by R471 and C452 and amplified by IC412 (LM386 – Audio Amplifier), with the level adjusted by RV401. The amplified signal goes to pin 9 of CON401 (DB-15). 2.3 ANALOGUE SWITCH IC409 (74HC4053B) is a digitally controlled analogue switch, which consists of three single pole double throw switches. Placing a high (5V) or low (0V) on the control lines switches the ports. A controls the X ports, B controls the Y ports and C controls the Z ports. This switch ensures the same filtering can be used for both TX and RX signals were appropriate. 2.4 HIGH PASS FILTER The 300Hz high pass filter is an 8-pole 1dB Chebeyshev active filter that comprises of IC410 and associated components. Received audio is passed to IC408 from Pin 4 of IC409 where sub-audible tones below 300Hz are removed. TX (Mic) audio is also fed into IC408 via IC 409 (Pin 4) where sub-audible voice products below 300Hz are also removed. 2.5 Sub Audible Tone Circuits * 2.5.1 CTCSS/DCS DECODE CIRCUITS Discriminated audio from Pin 9 of IC6 (on RF board) is fed into a 6th order Chebeyshev 250Hz low pass filter (IC411-B and associated components form the first 2 poles). The output is fed through the analogue switch, IC409, to IC410 (pin 8), which is a 6th order low pass Butterworth switched capacitor filter. The output from the Butterworth filter (Pin 3 of IC410) is then fed to the remaining second 4 D200 THEORY OF OPERATION Page 4 of 8 poles part of the 6th order Chebeyshev filter (IC411-D, one of IC410’s internal operational amps and associated components. The combination of filters gives a 4dB ripple low pass filter when programmed for 250 Hz. The remaining internal operational amplifier of IC410 forms the squaring circuit. This signal is compared the pre-programmed CTCSS/DCS of the MPU (via pin 32). If matched then valid data is decoded and the audio enable lines go high (pin 48 of microcontroller), along with LED401, lighting the green LED. Audio is released through pin 9 of DB-15 Connector. If unmatched, the busy L.E.D. (orange) is lit. 2.5.2 CTCSS/DCS ENCODE CIRCUITS The SAT squelch signal is produced as a 3-bit parallel word at Pins 19, 20, and 21 of the micro controller (IC401). This is converted to an analogue signal by resistors R481, R482 and R483 and fed through the analogue switch (IC409) into the 6th order Butterworth clock tuned low pass filter (pin 8 of IC410)). The filtered encode output (Pin 3 of IC410) is fed to the sub-audible gain control circuit (IC411-A and RV402) and then fed to the audio mixer circuit of the RF board. 2.6 TWO TONE DECODE CIRCUITS Two tone uses fr…
