Theory of Operation Introduction This section explains the general operation of the ASTRO Spectra/Spectra Plus Consolette. For more detailed information about the ASTRO transceiver, refer to the applicable ASTRO Spectra/Spectra Plus operator’s manual or service manual. Provisions have been made for the connection of voice recorders to the ASTRO Spectra/Spectra Plus Consolette.
Theory of Operation: General • The power supply converts AC power into DC power for use by the radio’s transceiver and the Audio Interface board or optional Tone Remote Control board. The ASTRO Spectra/Spectra Plus control head and speaker are present in all W7 models. W9 Digital Remote Control models do not have a control head or speaker. Refer to the appropriate ASTRO Spectra/Spectra Plus radio user’s guide for information regarding the operation of the control head.
Theory of Operation: Audio Interface Board Audio Interface Board General Description The TRN7391C Audio Interface board (AIB) serves as the central interface for all internal and external components of the ASTRO Spectra/Spectra Plus Consolette. All signals are routed through the AIB where processing may occur. Most audio paths incorporate some processing, while most control and data signals are passed unaltered.
Theory of Operation: Audio Interface Board Speaker audio is available at Accessory Connector 2, pins 14 and 15 (REMOTE_RX+ and REMOTE_RX–, respectively) for use with Digital Remote Control models. Speaker audio level is factory set but can be adjusted using Customer Programming Software. An array of resistors capable of dissipating 10 watts provides a 16Ω impedance for the desksets. To enable this audio output, S101-7 must be ON.
Theory of Operation: Tone Remote Control Board Spectra/Spectra Plus radio user’s guide). S101-3 determines the method in which the emergency is triggered. SPKR_UNMUTE is available at Accessory Connector 2 pin 25 as an output to provide an indication to accessories when the radio is receiving valid audio and the speaker is unmuted. This signal is configurable for either active-high or active-low operation using jumper J15. See Table 2 on page 9.
Theory of Operation: Tone Remote Control Board Voice HLGT FT 120 ms 40 ms Amplitude LLGT Time Figure 8. Remote Key-Up Table 12.
Theory of Operation: Tone Remote Control Board Detailed Description Control Point Monitor The ASTRO Spectra/Spectra Plus Consolette with the TRC option (L146) supports Control Point Monitor as defined by the FCC. The local Consolette speaker will unmute for remote audio that is being passed from the remote device to the Consolette to be transmitted. When the local microphone is keyed, the local speaker will be muted to voice audio.
Theory of Operation: Tone Remote Control Board contains an MF10 dual switched capacitor filter and a dual op-amp for summing purposes. The notch filter is formed by summing together the highpass and low-pass outputs of the filter IC. The MF10s on both HY1 and HY2 require a high-frequency clock input that is derived from a divider circuit (U127 and U129) and the MPU “E” clock. The output of the clock divider circuit (FILTER CLK) is a 110.4 kHz square wave that is used by the MF10s to create the filters.
Theory of Operation: Tone Remote Control Board The input from the phone line is applied to U112 op amp 1 pin 2, along with the line driver audio-canceling voltage (described previously) via S101-7 and S101-8. The gain of U112 op amp 1 is controlled by FET transistor Q113. The lower the DC gate voltage on Q113, the higher the gain, since a more negative gate voltage tends to turn off the FET, creating maximum feedback resistance across pins 1 and 2 of U112 op amp 1.
Theory of Operation: Tone Remote Control Board pin 41). The input to this pin is a 0-5V peak-to-peak square wave. The frequency of the square wave depends on the particular guard/function tone being sent. The microprocessor determines which tone is being sent and then takes the corresponding actions. AGC Circuit Operation The output of U112 op amp 4 feeds reference comparators (U117 op amps 2, 3, and 4) of the AGC circuit. If the peak voltage at the input exceeds the threshold of U117 op amp 4 (+5.
Theory of Operation: Tone Remote Control Board On the TRC board, A+ is converted to regulated 9.6V through U100. From this 9.6V source, several comparator voltages are produced. SWB+ is routed to a 5V regulator (U132) on the TRC board, which provides regulated 5V to all of the logic ICs. One exception to the IC power distribution is the Serial I/O IC (U131). This IC needs to be powered at all times, regardless of the state of S101-1.
Theory of Operation: Tone Remote Control Board Smart Modem Protocol (SMP) Control The ASTRO Tone Remote Control Board also provides an RS232 port through which the Consolette communicates with an ASTRO Console Interface Module (ACIM) using the Smart Modem Protocol (SMP). NOTE: For correct operation, the ACIM must be connected to a Gold Series Console programmed with System 3.0 Conventional or later.

Theory of Operation: Power-Up ! Caution Power-Up Do not connect anything to Accessory Connector 1 other than the supported ACIM connection. Damage could occur to the Consolette and unsupported external devices. The ON/OFF power button located on the ASTRO Spectra/Spectra Plus control head is disabled before shipment. Therefore, the station is immediately operational when its power cord is plugged into a live AC outlet.

Appendix A - Cross Patch Configuration General Description The Cross Patch provides interoperability between two systems on different bands, analog or digital or trunking. An interface cable can be built to allow the interconnection of two ASTRO Spectra/Spectra Plus Consolette stations to form a repeater system. The information received by Consolette 1 will be retransmitted or repeated by Consolette 2. Similarly, information received by Consolette 2 will be retransmitted on Consolette 1.
Appendix A - Cross Patch Configuration Level Settings Consolette 1 to Consolette 2 Path 1. Connect Consolette 1 to Consolette 2 via the cable described above. 2. Connect a signal generator or communications analyzer to Consolette 1. 3. Connect Consolette 2 to a modulation analyzer or communications analyzer. Set the analyzer up to measure deviation level. 4. Apply a –47 dBm on channel RF signal modulated with a 1 kHz tone at 60% FSD into Consolette 1.
Appendix A - Cross Patch Configuration ! Caution When using the Cross Patch, you may exceed the duty cycle rating of the Consolette. If this condition is expected, the customer may want to reduce the RF power output of the Consolette.
