INTRODUCTION The TS4000 is a high-speed radio modem that consists of a modem board, radio transceiver board and metal enclosure. The radio transceiver board connects to the modem board with a flexible printed circuit. Radio Transceiver Board The radio transceiver board for this application is an E.F. Johnson DL3422. This device is being used without any modifications. The DL3422 has received FCC type acceptance with an FCC ID of ATH2423422-007. All circuit descriptions and details for the radio transceiver can be found in the type acceptance document for the DL3422. A copy of this has been included with this application. The radio transceiver is available in a frequency range from 132-174 MHz and includes a temperature stable reference oscillator with a frequency stability of ± 2.5 PPM. Modem Board The modem board provides the serial data interfaces that the user’s equipment interfaces to. The modem board also controls the operation of the radio transceiver. This control includes controlling the radio power and frequency and also controlling the modulation, data rate and frequency deviation of the transmit signal. Note that it is this transmit signal that defines the emission bandwidth and spectral efficiency. Radio Flex Circuit A flex circuit is used to interconnect the radio transceiver board to the modem board. This flex circuit is also used to interconnect the serial port 2 connector to the modem board. The J11 interconnecting diagram included with the modem board schematic provides the specific connections provided by the flex circuit for connecting the radio transceiver to the modem board.

Tested To Comply With FCC Standards FOR HOME OR OFFICE USE TS4000

Type Acceptance Information for TS4000 Radio Modem with 3422 Transceiver Proposed FCC ID JWFTS4000C Teledesign Systems, Inc Confidential InformationPage 1 OPERATION DESCRIPTION Radio Channel Programming and Switching Up to 99 radio channels can be pre-programmed into the modem board’s non-volatile memory with a PC based programming software. This software is only available to authorized dealers and service centers. The user can switch between pre-programmed channels by sending an ASCII control string through one of the modem board’s serial ports. The frequency of the radio transceiver is controlled by the microcontroller using the SPI port. This port directly controls the PLL (Phase Lock Loop) on the radio transceiver board. The microcontroller monitors the lock condition of this PLL using the lock detect signal from the radio transceiver. Radio Power Control The transmit power is adjustable from 0.1 to 5 watts. The actual value is adjustable by the end user using the TS4000 configuration software but can never be set over the maximum value of 5 watts. The modem board controls the radio power by setting the radio power DAC on the radio transceiver. This DAC is controlled through the radio transceiver’s SPI interface. The maximum value that this circuit can be set for is configured when the unit is tuned up. This prevents the user from setting the output power higher than the maximum allowed. Data Rate and Emission Masks The modulation data rate is controlled by the microcontroller using the clock circuitry (described above). The modulation data rate, combined with deviation, controls the occupied bandwidth of the transmitted signal. The allowed occupied bandwidth depends on the channel bandwidth and the corresponding emission mask of the signal. Please reference the emission designator calculations in the front of this document for the maximum modulation data rate and deviation allowed for each designated emission. The maximum modulation rate that a unit can operate at is configured by Teledesign Systems when a unit is tuned up. The TS4000 configuration software allows the user to adjust the modulation data rate but can never set it above the maximum value that is configured when the unit is tuned up. The deviation is controlled by the modem board based on the modulation data rate that the unit is set for. Spectral Efficiency This equipment is capable of supporting a minimum of 4800 bits per second per 6.25 kHz of channel bandwidth. This allows this equipment to support the latest FCC spectral efficiency requirements.

Type Acceptance Information for TS4000 Radio Modem with 3422 Transceiver Proposed FCC ID JWFTS4000C Teledesign Systems, Inc Confidential InformationPage 1 MODEM BOARD CIRCUIT DESCRIPTION Microcontroller and Memory The microcontroller, U16, controls and manages all activity on the modem board. The microcontroller operates at an internal clock rate of 25.1 MHz that is derived from crystal Y1 which oscillates at 32768 Hz. The microcontroller reset is controlled by U2 which monitors the power supply. The program for the microcontroller is stored in flash memory U18. This program can be updated by downloading a new version through the serial port using PC based upgrade software supplied by Teledesign Systems. The chip selects for the flash memory are controlled directly by the microcontroller. The dynamic data for the microcontroller is stored in SRAM (static RAM) U17. Serial EEPROM U15 provides non-volatile storage for the microcontroller. The serial EEPROM is interfaced to the microcontroller through an SPI bus which provides high speed synchronous serial communication. The microcontroller interfaces to a number of other chips on the board through either the SPI bus or through the 16 bit parallel data bus. For the parallel interface, the microcontroller provides all the address decoding for the chip selects. Data Interface There are two serial data interfaces that are used to connect to external equipment. Serial interface 1 is an asynchronous serial interface which is controlled with the SCI (Serial Communications Interface) of the microcontroller. The serial interface lines of the microcontroller are fed into U13 and U27 which provide signal buffering and level translation. The RS-232 buffer, U13, generates its own high (+6 to +10 VDC) and low (-6 to -10 VDC) voltages with a charge pump circuit which oscillates at about 10 kHz. The low voltage of the charge pump is regulated with D5 and is used for some of the analog circuits in the modulation and demodulation sections. The TTL buffering is handled by U27. Serial interface 1 can be configured to operates at either RS-232 or TTL signal levels using jumper block JB1. The RS-232 standard defines voltage signal levels between -25 and +25 volts. TTL signal levels are between 0 and 5 volts. Serial interface 2 is a synchronous or asynchronous serial interface and is controlled with one of the ports of the SCC (Serial Communications Controller) U21. The SCC is controlled by the microcontroller using the parallel bus. To provide the correct parallel interface timing between the SCC and the microcontroller, U25 is used to delay the SCC chip select. Serial interface 2 operates at RS-232 signal levels using U12 to provide signal buffering and level translation. The RS-232 buffer, U12, generates its own high (+6 to +10 VDC) and low (-6 to -10 VDC) voltages with a charge pump circuit which oscillates at about 10 kHz. Power Regulation The power input into the modem can be from 9 to 28 volts DC. This input is diode protected with D22, D23 and D20. The main power regulation is provided by dual switching regulator U20 in conjunction with level adjuster U24. The switching regulator switches at a frequency of approximately 300 kHz. To produce the voltages the switching regulator uses diodes D17, D19, D14, D13, D18 and D21 and transistors Q4 and Q5. The switching regulator produces a 13.0 volt power source and a 5 volt power source. The 13.0 volt power source feeds into the final stage of the radio frequency amplifier of the radio transceiver. The 5 volt power source is used for most of the modem board’s digital circuitry. For the analog circuits, linear regulator U11 produces a temperature and voltage stable 5 volt power source from the 13.0 volt source. Type Acceptance Information for TS4000 Radio Modem with 3422 Transceiver Proposed FCC ID JWFTS4000C Teledesign Systems, Inc Confidential InformationPage 2 Diagnostics The microcontroller monitors a number of signals using an A/D (analog to digital) converter internal to the microcontroller. To prevent over and under voltage into the A/D converter, diodes D15, D16, D6, D7, D8, D9, D10, and D11 are used. To monitor the temperature on the board, U1 is fed into the microcontroller’s A/D converter. To indicate the state of the modem, LEDs DS1, DS2, and DS3 are used. These are controlled by the microcontroller using transistors Q12, Q13, and Q14 to buffer the signals. Clock Circuitry The modem board generates a variable rate modulation clock which controls the over the air data rate of the modulator and demodulator circuits. The modulation clock can be varied between 1 and 10 MHz. The modulation clock is derived from the microcontroller’s main clock. The microcontroller’s main clock is fed into a divider U23 which generates the modulation clock. The divide ratio of U23 is partially set and by latch U19 that is loaded through the SPI bus. The divide ratio is tweaked using decoder U26 and divider U22. The divide ratio of U22 is set through the microcontroller’s SPI port. Modulation and Demodulation ICs U7 and U9 perform the modulation and demodulation of data. The modulation used by the modem board is selectable for GMSK (Gaussian Minimum Shift Keying) or four level FSK (Frequency Shift Keying). This is selectable by the user using the TS4000 configuration software. GMSK When GMSK modulation is used, U9 provides the modulation and demodulation functions. Data is fed into and out of this chip through one port of the SCC (Serial Communications Controller), U21. The GMSK chip filters the transmit waveform by passing NRZ (Non-Return to Zero) data through a Gaussian low pass filter with a BT of 0.5. The BT of 0.5 indicates that the 3 dB bandwidth of the Gaussian filter is 0.5 of the bit rate. Q7 and Q6 are used to adjust the demodulation performance of U9. Four Level FSK When 4LFSK (Four Level Frequency Shift Keying) modulation is used, U7 provides the modulation and demodulation functions. Data is fed into and out of th…
