MDS 05-3624A01, Rev. A JUNE 2000 Data Transceiver MDS OEM-L/ss QUICK START GUIDE Below are the basic steps for installing the transceiver. Detailed instructions are given in “Installation Steps” on page 8 of this guide. 1. Install and connect the antenna system to the radio • Use good quality, low loss coaxial cable. Keep the feedline as short as possible. • Preset directional antennas in the direction of desired transmission. 2. Connect the data equipment to the radio’s INTERFACE connector • Connection to the radio must be made with a DB-25 Male connector. Connections for typical sys- tems are shown below. • Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired. • Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.) The markup had a question about this figure. Please verify 3. Apply DC power to the radio (10–30 Vdc @ 1.5 A minimum) • Observe proper polarity. 4. Set the radio’s basic configuration with a Hand-Held Terminal (HHT) • Set the transmit frequency ( TX xxx.xxx ). • Set the receive frequency ( RX xxx.xxx ). • Set the network address ( ADDR xxx ). • Set/verify the data rate using the BAUD command. The default setting is BAUD 9600 8N1 . (Refer to “TRANSCEIVER PROGRAMMING” on page 14 for command details.) 5. Verify proper operation by observing the LED display • Refer to Table 5 on page 14 for a description of the status LEDs. • Refine directional antenna headings for maximum receive signal strength using the RSSI command.

Ladies/Gentlemen, Please allow us to correct the Emission Designation stated in the Form 731 and page 7 of our test report # MIC28-F90. The calculation of the necessary bandwidth is incorrect since we applied the incorrect level of FM modulation. The correct level of FM modulation shall be 4, not 2 as we used for original calculation, below please find our recalculation: For Channel Spacing = 12.5 kHz, D = 2.5 kHz max, K=1, M = Max. Data Rate inkb/s / Level of FM = 9.6/4 = 2.4 Level of FM = 4 Bn = 2M + 2DK – 2*2.4 + 2+2.5*1 = 9.8 kHz Our measurements per plots # 1 to 3 in Exhibit 9 of the test report show the 99% BW of 9.2 kHz maximum which agrees with calculation. The Emission Designation is 9K8F1D Please allow us to correct the emission designation as above in our application. Please contact us if if you have any questions. Regards, Tri M.

Operational Description

2.0 Description of Device Operation 2.1 General Operation The EL-705 Data Transceiver is an OEM narrow band radio designed to operate on 12.5kHz channels, meeting the requirements of FCC Part 90 and FCC Part 15. 2.2 Summary of RF Parameters Transmitter Type: Synthesized, 12.5kHz steps. Frequency Range: 450 to 470MHz. Power Output: +33dBm, nominal. Master Clock Reference: 16MHz TCXO, +/- 1.5ppm stability. Receiver Type: Double conversion superheterodyne. Frequency Range: 450 to 470MHz. 1 st IF Frequency: 45MHz 1 st LO Range: Low-side injection 405 to 425MHz, 12.5kHz steps. 2 nd IF Frequency: 450kHz. 2 nd LO Frequency: Low-side injection 44.550MHz, fixed. 2.3 Description of Circuit Functions The following is a summary of the operation of the EL-705 Data Transceiver, and is referenced to the block diagram shown in Figure 1. 2.3.1 Receiver Receiver Front End RF for both transmit and receive is connected to the OEM transceiver board thru the BCN antenna connector J201. In the receive mode, the received signals first pass thru a 5 th order lumped-element harmonic lowpass filter. This filter suppresses all signal energy above the receive band of interest. Following this lowpass filter, the received signals are passed thru an antenna switch which is in the off mode in receive and directs the signal energy to a 3-section helical bandpass filter, FL200. The output of FL200 is then passed thru a low-noise RF preamplifier, Q201, and then thru another 3-section helical bandpass filter, FL201. The combination of both 3-section helical filters has approximately a 20MHz bandwidth, suitable to cover the 450 to 470MHz band and provide sufficient rejection of the undesired out of band signals. The filtered and amplified received signals are then passed thru to a double-balanced IC mixer, U301 that, in conjunction with the 1 st local oscillator signal, downconvert the desired signal to the 1 st IF of 45MHz. The 1 st conversion process to 45MHz utilizes a low-side injection method. Since the receive range is 450 to 470MHz in 12.5kHz steps, the 1 st LO will cover 405 to 425MHz in 12.5kHz steps. 1 st Intermediate Frequency The 1 st IF is filtered by a 3-pole monolithic crystal filter, FL302. This filter has a center frequency of 45MHz and has a bandwidth of 15kHz. Since the first mixer has gain, no IF amplifier is needed. Hence the filtered output of the 1 st IF is fed directly to the SA-606 FM demodulator IC for further processing. 1 st Local Oscillator The first conversion process mixes the filtered and pre-amplified received signal with a locally generated signal source that is phase locked to a 16MHz master TCXO crystal. This 1 st local oscillator is generated from a VCO circuit consisting of Q303 and Q307 and its associated components. The VCO output signal is buffered by U302, and a portion of this signal is fed back to the PLL synthesizer IC, U300, which divides it down using a set of on-chip programmable dividers and compares the result to a divided-down version of the 16MHz master clock in a phase detector. Any static or rotating phase difference between the two signals generates a series of current pulses at a rate of 50 kHz which are converted to a steering voltage in the loop filter. This filtered voltage is then used in concert with a variable-capacitance diode in the VCO circuit to correct this offset to zero. The loop filter also serves to control loop dynamics, suppress the 50kHz phase detector sampling frequency, and noise. The programmable feedback divider string within U300 can also divide the VCO by a fractional part, so smaller than 50kHz increments can be had; thus, 12.5kHz steps can be generated. The other VCO output is split into two paths. One path is filtered by a single-section elliptic lowpass filter to reduce the harmonic content, and the result serves as the 1 st local oscillator signal in the 1 st conversion process already described. The second signal path is fed to the disabled transmitter driver and is not used in receive mode. The 1 st local oscillator frequency range is 405 to 425MHz in 12.5kHz steps. 2 nd Mixer and FSK Data Demodulator The output of the 1 st IF at 45MHz is fed to the FM/FSK demodulator IC, U303. Here, the incoming 45MHz 1 st IF is downconverted to a 2 nd IF of 450kHz and filtered by two 9kHz ceramic bandpass filters FL300 and FL301. These filters provide the final channel selectivity. This downconversion process is accomplished by an on-chip double balanced mixer in conjunction with the 2 nd LO VCO using low-side injection. This VCO runs at 44.550MHz and is designed around an active transistor on U303 in concert with an external VCO tank circuit. Again, as with the 1 st LO, a portion of this 2 nd LO signal is sent to the PLL synthesizer IC, U300, where it is divided down by 891 to yield 50kHz and is then phase locked with the 16MHz master clock TCXO divided by 320 (50kHz). The resulting phase difference is filtered by a loop filter, and the resulting loop correction voltage is coupled to the 2 nd LO VCO, thus completing the loop. This 2 nd LO frequency is fixed at 44.550MHz. After the ceramic bandpass filters, the filtered 450kHz signal is hard limited by a set of limiting amplifiers, and the result is mixed together with a 90-degree phase shifted version of itself. This quadrature demodulation process, after removal of the 450kHz carrier components, yields the received FSK data. Received signal strength indication (RSSI) is derived from the limiting amplifiers, and provides an indication of the received signal level from the transmitter. The FM demodulator output is then sent to two active lowpass filters, U110 and U112. One filter provides a DC estimate, and the other is a data-rate filter. The comparison of these two signals provide received data timing information, and the output of just the data-rate filter is the recovered 4-level FSK data. Two bits per symbol are sent, thus 4- level FSK, and the effective maximum payload data bit rate is 9600 bits pe…
