Maintenance ManualMM101271V1 R2ASitePro™ ControllerShelf Assembly EA101209V1

ADDENDUM NUMBER 1 TO SITEPRO MAINTENANCE MANUALMM101271V1 R2AThis addendum adds an improved high-speed data (HSD) adjustment procedure to the following manuals:• SitePro Controller Maintenance Manual MM101271V1 R2A• SitePro Simulcast Controller Card Maintenance Manual MM101509V1 R1A• GPS Simulcast Systems (with SIM and SitePro Controllers)System Alignment and Field Testing Procedures MM101724V1 R1AThis improved procedure allows the adjustment to be made on-the-fly without the need to put the SiteProController into Test Mode. The adjustment range is the same as with the earlier procedure [two hexadecimaldigits 00-FF]. The values entered will take effect immediately. By writing these values to EEprom they willpersist through a reset. From a hyper-terminal connected to the SitePro Controller serial port1 perform thefollowing:HIGH-SPEED DATA ADJUSTMENT PROCEDUREAdjust HSD by modifying the pot setting. Once the correct level is found it must be stored in permanentmemory.1. Adjust the 'real time' high-speed level:SI2C 50 1 5 <rtn> sets slave device for all subsequent read/write operations (50 is EE pot)2. Read current data from the HSD pot:RI2C A9 A9 <rtn> reads current data at specified address range (A9 is location of the HSD pot)3. Write new values to the HSD pot. The value from step 2 provides an initial set point. The command towrite a value is:WI2C A9 xx <rtn> were xx is the hexadecimal value written to the HSD pot. Write new valuesuntil the desired deviation is achieved.4. Store the new value which achieves the desired deviation into permanent memory (novRAM) using thefollowing commands:SI2C A6 2 5 <rtn> sets slave device for all subsequent read/write operations (A6 is EEprom)WI2C 03 xx <rtn> writes new value of the HSD Pot in EEprom (03 is location of HS level)RI2C 03 03 <rtn> reads current value of the HSD Pot from EEprom (to check if writtencorrectly) 1 This procedure can also be performed through an ethernet port. Refer to the applicable manual for instructions.

MAINTENANCE AND SERVICEMM101271V1 R2A 135.0 MAINTENANCE AND SERVICEThis manual provides maintenance and servicing information for M/A-COM SiteProController Shelf Assembly EA101209V12. Production versions of this shelf consist of thefollowing components:• Shelf Assembly MA101080V1• Interconnect Board Assembly (A1) CB101073V1• Controller Board Assembly (A2) CD101069V1• SitePro Modem Board (A2-A1) CB101074V1• Rockwell Modem InterfaceCard Assembly (A3) ROA 117 2247Rockwell Modem Assembly (A7) RYTUZ 921 01/1• Analog Board (A4) CB101070V1• Power Supply Module (A5) PS-PS101328V1• Display Module (A6) MA101082V1Display Board Assembly (A6-A1) CB101077V1Cable (A6-W1) CA101222V1• Input Cable to the Power Supply (W1) CA101211V1• Output Cable from the Power Supply (W2) CA101212V15.1 APPLICATIONSThe SitePro Controller can be installed and configured for several different stationapplications. Initially the basic configuration is for the EDACS Station Trunking Shelf.This shelf enables the station to function as part of an EDACS trunked communicationsystem by providing digital signaling and control of the associated base station. Inaddition, the SitePro Controller provides an interface between the base station repeater,the Site Interface Module (SIM) and other channel SitePro Controller(s) at the sametime.5.2 COMPATIBILITY AND MIGRATIONThe SitePro Controller, with the exception of the Site Controller, is compatible withGETC compatible devices as follows:• Downlink GETC• SIM• SureCall• Hotline• Site Sentry 2 The Service Technician(s) should always consult any application manuals, Software Release Notes (SRN), and SpecificCustomer information provided with the system whenever the equipment requires service or repair.

MAINTENANCE AND SERVICE14 MM101271V1 R2AThe requirements for compatibility and migration are that:1. The SitePro Controller will only switch modes if the Control Channel fails or aconfiguration command is received. The SitePro Controller will, however, changemodes as currently implemented by the GETC. For example, the SitePro ControllerControl Channel can switch modes, without failure or configuration command, if itdetects carrier.2. For High Speed Data Modulation, the SitePro Controller has a separate Analog Board(A4) providing software configurable filtering, which is compatible with high-speeddata types.5.3 SYSTEM EXTERNAL INTERFACES(SitePro Trunked Interface Specification)The following is a description of all electrical connections to the SitePro Controller. Allinput/output definitions are relative to the SitePro Controller. This configuration supportsEDACS, Simulcast and Voted systems. The analog and digital control signals provide aninterface to a variety of base stations and are grouped by functionality.5.3.1 Station Control• LocRxAudio - Analog inputMASTR III level = 1 Vrms, Zin = 100Kohm, bias = ac coupledThis signal is unfiltered local receiver audio from the base station also calledVolume/Squelch or VolSqHi and carries either High Speed Data (controlsignaling/digital audio) or Low Speed Data with analog audio. The two componentsare internally separated.• RUS - Digital TTL active high inputThis signal is the Receiver UnSquelch signal from the base station and is activatedwhen a carrier of sufficient signal strength (as determined by the squelch pot setting)is present.• LSD - Analog outputlevel = 300 mVrmsZout = 100ohm, bias = 0 voltsThis signal is the Low Speed Data output to the base station. The signal isconditioned through a low pass filter to remove frequency components above 300 Hzto allow multiplexing with analog voice audio.• HSD - Analog outputlevel = 1.1 VrmsZout = 100ohm, bias = 0 voltsThis signal is the High Speed Data output to the base station modulator. The signal isconditioned through a specially designed filter needed to meet precise RF modulationbandwidth limitations.

MAINTENANCE AND SERVICEMM101271V1 R2A 15• LocPTT - Digital active low open drain outputThis signal is the Local PTT control. This line, when low, will key up the base stationtransmitter and select the local receiver audio source for transmission.• RemPTT - Digital active low open drain outputThis signal is the Remote PTT control. This line, when low, will key up the basestation transmitter and select the remote audio source for transmission.• A/DmodCtrl - Digital output TTLThis is the Analog/Digital Modulation Control signal. When high, HSD is routed tothe base station transmit. When low, LSD/audio is routed to the base station transmit.• HSAcq - Digital output open drain outputThis is the High-Speed Acquisition control signal. A high or low signal produces acorresponding high or low time constant in the limiter circuit.• LocRxMute - Digital active low output (8.5 volt low Z source)This signal is the Local Receiver Mute control. This line, when low, blocks therouting of receiver audio to the base station transmitter and line out. Muting occursduring HSD transmission, no valid carrier present, or no valid LSD present.• Walsh1/Walsh2 - Digital output TTLThese two signals are combined to form a two bit Walsh Function DAC. This signalis the Low Speed Data source.• Synth_Clk – Digital open drain outputThis signal provides the clock source for loading the base station frequencysynthesizer (required for MIIe). Data is clocked on the negative edge of the clock.The baud rate is approximately 2.4Kbaud.• Synth_Data – Digital open drain outputThis signal provides the data source for loading the base station frequencysynthesizer (required for MIIe). Data is clocked on the negative edge of the clock.The baud rate is approximately 2.4Kbaud.• Synth_LdEn – Digital open drain outputThis signal is the Synthesizer Load Enable control.

DESCRIPTIONMM101271V1 R2A 196.0 DESCRIPTIONThe SitePro Controller is essentially a processor with audio filtering and specialized I/Ocapability. Flexibility in design allows the SitePro Controller to be configured to functionin many applications as suggested in the APPLICATIONS section. The SiteProController software is stored in flash memory. Configuration Data is stored inNOnVolatile Random Access Memory (NOVRAM).The Controller Board, Rockwell Modem, Analog Board, Power Supply, Display Module,and Display Board are mounted on a tray and enclosed in shelf (Figure 2 - SiteProController Shelf Assembly). The SitePro Controller shelf is a one-rack unit assembly(1.75-inches x 19-inches), which mounts in a standard 19-inch wide equipmentcabinet/rack. This shelf does not slide out, but by reversing the mounting ears can bemounted approximately 2/3 of the way out of the cabinet for troubleshooting.Controller Board A2 uses Dual High Speed Diodes BAV99’s for surge protection on allTTL inputs. However, maximum surge protection is achieved when the SiteProController is grounded to the cabinet earth-ground using Lightning Protection CircuitryGround Kit 344A4500 and the Cabinet Grounding strap Kit 344A4730. Specific detailsfor installing these grounding kits are found in the LIGHTNING PROTECTIONsection 10.0 of this manual.6.1 INDICATORS AND CONTROLSThis section describes the indicators and controls visible and accessible from the frontpanel of the SitePro Controller Shelf Assembly.There are two hinged doors on the front panel of the shelf assembly. Each door has awindow so that indicators mounted on Control Board A2 and Rockwell Modem InterfaceCard A3 can be seen. Opening the Controller Board door provides access to ResetPushbutton switch S1. This door also provides access to PROGRAMMING andDIAGNOSTIC SERIAL PORT J8. Programming is available through this port.The circuit boards can be removed from the shelf assembly through these doors.6.1.1 Indicators6.1.1.1 Controller Board Power IndicatorGreen LED indicator D12 provided on the Controller Board indicates when power isapplied to the shelf. This indicator is visible by looking diagonally through the window inthe hinged door on the front panel of the shelf.6.1.1.2 Controller Board Status IndicatorsFour Red LED status indicators L1 thru L4 (D1 thru D4) are visible through the windowin the hinged door. These indicators show the state of operation of the SitePro Controller.The interpretation of these indicators depend on the system application (refer to theSitePro Controller configuration manual for the specific application).

DESCRIPTION20 MM101271V1 R2AGreen ETHERNET indicators ETH0 and ETH1 are also visible through the window inthe hinged door. These indicators indicate when a compatible source is connected toETHERNET 1 or ETHERNET 2 ports.There are six other LED indicators on the Controller Board that are not visible from thefront panel. Yellow LEDs D7 and D10 indicate when there is transmit activity on ETH0and ETH1. Yellow LEDs D6 and D9 indicate when there is receive activity on ETH0and ETH1. Green LEDs D5 and D8 indicate when there is link activity (refer to EthernetPorts, section 7.3.7).6.1.1.3 Rockwell Modem Interface Card IndicatorsThere are five Red LED indicators on Rockwell Modem Interface Card A3. These LEDsare visible through the window in the hinged door and indicate +5V, +12V, -12V, RLSDand CTS respectively. Received Line Signal Detect (RLSD) indicates data is beingreceived. Clear-To-Send (CTS) indicates a control signal is being sent to the CPUselector.6.1.1.4 DisplayEight-character LED Display Board A6-A1 mounts between the two hinged doors on thefront panel of the SitePro Controller Shelf Assembly. Green LED D1 indicates POWERON to the shelf. This display displays Channel Status and Channel Information.6.1.2 ControlsReset Pushbutton Switch S1 is the only control available on the front panel of theSitePro Controller Shelf Assembly. It is used to reboot the SitePro Controller.6.2 ROCKWELL MODEMThe 9600 Baud Rockwell Modem Board RYTUZ 921 01/1 mounts on top of ModemInterface Card A3 (ROA 117 2247). This Modem Board is used to generate a 9600 baud,fast-train, synchronous, serial data stream suitable for transmission over audio (phone)line or microwave link. The data stream is sent over a full-duplex, four-wire, dedicated3002 grade telephone line.Receive and Transmit Phone Data Lines are two balanced pairs carrying Modem data toand from the station where the data is combined with station audio (voice) and routed tothe Remote Line input and Line output.In addition to transformer isolation and conditioning provided by the SitePro Controller,the modem provides automatic adaptive signal equalization. The Rockwell Modemdemodulates the input signal and the resulting data is transferred using a serial interfacebetween the Rockwell Modem and the controller.The modem senses a received signal by initiating a training state upon detecting anincrease in the input signal level. The modem begins processing data at the end of thetraining state if the input signal is still above the nominal -40 dBm receiving thresholdvalue. Otherwise, the modem returns to an idle mode at the end of the training state if theinput signal is below the nominal receiving threshold value.

The SitePro Controller can communicate with other devices such as theCommunication System Director (CSD), IMC, and RF Station. Communicationoccurs primarily through an RS-232C serial interface normally operating at 38.4kilobaud. For a SitePro Controller interfacing with a Site Interface Module (SIM)this is set to 38.4 kilobaud.2. The SitePro Controller can communicate with other SitePro Controllers in the normalmode of operation, over a Backup Serial Link (BSL). The link uses 0-13.8 VDClevels and operates at 38.4 kilobaud and is ordinarily used in a bus configuration. Fora SitePro Controller interfacing with a SIM this is set to 38.4 kilobaud.3. A timing signal called the Frame Sync Line (FSL) helps arbitrate the use of the BSLserial bus. The FSL is also used for timing purposes. In the station configuration, FSLsignals use 0-13 VDC levels to produce a periodic negative going pulse (2.5 ms wideevery 30 ms).4.

CIRCUIT ANALYSIS24 MM101271V1 R2A7.0 CIRCUIT ANALYSISThe Theory of operation of each circuit board/card and module used in SitePro ControllerShelf Assembly EA101209V1 is described in the following paragraphs. Refer to theBlock Diagram in Figures 3 and 4 and Outline and Schematic Diagrams as listed in theTABLE OF CONTENTS.The SitePro Controller is a Base Station Controller with redundant communication links[Backup Serial Links (BSL’s)]. The BSL’s provide for inter-channel communication.Two 10Mbit Ethernet Ports provide system level communication. The BSL’s providetrunking communications as well as site configuration and database messaging. OneEthernet port is dedicated to Management System information. The second Ethernet Portis not supported at this time.The SitePro Controller and System Interface Module (SIM) will use the primary BSL fortrunking information and limited management system information. The secondary linkwill ensure continued trunking operation in the event of a primary BSL failure.The SitePro Controller/base station interface for digital information, both receive andtransmit, is 9.6k baud synchronous data. Additional digital control information isprovided via discrete I/O at both the base station and controller. The following diagram(Figure 2) is a high level picture of the SitePro Controller and external interfaces.7.1 SHELF ASSEMBLYSitePro Controller shelf Assembly EA101209V1 is a 19” Rack Mount, one Rack Unitdevice. It is enclosed to reduce emissions and interference with other devices. Serialports, Ethernet, power, and I/O connections are accessible at the back of the shelf (Figure1). The serial port connections (6 OVER 6 PHONE LINES & SERIAL PORTS) arestacked two high using RJ45 type connectors (J14) and RJ11 type connectors (J4). TheEthernet connectors J5 & J6 (ETHERNET 0 & ETHERNET 1) are single height RJ45connectors.

CIRCUIT ANALYSIS28 MM101271V1 R2A7.3.2.1 Oscillator For Ethernet PHYsThis circuit consists of crystal oscillator circuit Y1 powered by 3.3 V applied to Y1, Pin4, Vcc. Oscillator circuit Y1 is biased on by resistor R49 connected to Y1, Pin 3, CTRLand produces 25 MHz on the output at Pin 3 through resistor R51 (OSC 25MHz). Thisoutput connects to the CLK25 inputs to the Ethernet 10 and Ethernet 10/100 MbitPHYs3.7.3.2.2 JTAG PortThis JTAG PORT circuit consists of buffer U1 (NC7SZ125M5). This circuit allowsprogramming directly to the microprocessor through connector J4. This circuitry is notpresently used.7.3.2.3 Board Insert Detection CircuitThis circuit consists of NPN transistors Q6 and Q7. When the Controller Board isinserted into a live Interconnect Board, the base circuits of these transistors are connectedto ground through connector J1B, Pins B1 and B32 at either end of J2. Connector J1B,Pin B1 is MATE-DETECT-A and J1B, Pin B32 is MATE-DETECT-B. With the base ofboth transistors at ground, they are held in the off state. This allows POWER ON to cyclehigh if the output of U41 is high. The POWER ON voltage is applied to Pin 2 of HotSwapTM Controller U37. If the base of either transistor (Q6 or Q7) is not connected toground, POWER ON will not be applied to the HotSwap Controller. Therefore, if thecard is not seated properly, power will not turn ON.7.3.2.4 Hot Swap™ ControllerHot Swap™ controller (HSC) U37 allows Controller Board CB101069V1 to be safelyinserted in or removed from Interconnect Board CB101073V1 while voltage is applied.Using external N-channel pass transistor Q5, the supply voltage to the Controller Board isramped up at a controlled rate. Hot Swap switch driver U37, Pin 6 controls the N-channelgate. A programmable electronic circuit breaker detecting over current by sensing voltageacross 15 milliohm resistor R153 protects against shorts. The RESET output (U37, Pin 1)is used to generate a system reset when the supply voltage falls below the voltage presetby resistors R167 and R168. The POWER ON input to U37, Pin 2 is used to cycle theController Board power. The 555 timer circuit (U40) is connected to the HSC chip so thatthe HSC can be automatically reset in the case of a circuit breaker fault.Because the Hot Swap Controller, U37, latches OFF if it senses an overload, a timercircuit has been added to occasionally turn it back ON. If the overload still exists, it turnsoff immediately but if the overload is not present, normal operation is restored. Thiscircuit is needed for unattended operation.The 555 timer is powered any time 5V is applied to the board since it is connected aheadof the Hot Swap Controller. As long as the HSC is ON, 5V is fed to inverter U42-2through D34. The resulting low on U42-4 holds U40 at reset.When the HSC turns power OFF, U42-4 goes high and the reset is removed. The timernow free runs with about a 1.1 second cycle time. U40-3 is high for about 0.7 sec and low 3 PHY is an Industry Standard for “Physical Interface.”

CIRCUIT ANALYSISMM101271V1 R2A 29for about 0.4 sec. U40-3 is inverted by U41. During the high part of the cycle, theresulting low at U41-4 holds the HSC ON pin low keeping the HSC OFF.When U40-3 switches low, U37-2, the HSC ON pin is allowed to go high through D35,pulled up by resistor R157. The HSC turns ON, but if the fault is still present, it turnsOFF within 40µs and the cycle continues. If the fault is gone, the 555 is held reset and theController Board resumes normal functioning.Capacitor C119 and resistor R191 act as a slugging filter on the FB input to prevent fasttransients on the 5V from causing the HSC to generate a reset. Likewise, capacitor C118and resistor R190 prevent large transients on the input 5V, i.e. when the RMIC is hotswapped, from causing the HSC to generate a reset due to a transient on the ON pin.7.3.2.5 3.3V RegulatorThe controller board is provided with 5 Volts and ±12 Volts from the Interconnect Board.Linear regulator U25 is used to provide 3.3 volts to be used by the majority of digitallogic on the Controller Board and the Board.The Hot Swap Controller (HSC) is used to ramp up the 5V-power rail at a controlledrate. This, in addition to other considerations, will allow the Controller Board to be hotswappable. The 5V output from this circuit will also power the 3.3-Volt regulator, thuscausing the 3.3 V power rail to also ramp up at a controlled rate. As mentioned above, theHSC has a built-in electronic circuit breaker.7.3.2.6 3.3V Power MonitorThe 3.3V Power Monitor (U31) uses a precision temperature-compensated reference andcomparator circuit to monitor the status of the 3.3V supply. If a loss of power is detectedan internal power-fail signal forces reset to the active state, which is low. When the 3.3Vsupply returns to a normal state, the reset signal is kept active for approximately 150 msto allow the power supply and microprocessor to stabilize. This 3.3V Power Monitorcircuit also monitors Reset Pushbutton S1 on the reset output, U31, Pin 1. If the reset ispulled low, by pressing S1, a reset signal is generated upon release. The output of U31 isheld in reset output (low) for approximately 150 ms.7.3.2.7 Test PointsTest Points TP1 thru TP10 are provided on the Controller Board as follows:• TP1 thru TP3, TP7, TP8 and TP10 are ground connections• TP4 is +12V• TP5 is +3.3V• TP6 is +5.0V• TP9 is WALSHCLK7.3.2.8 Programming Serial Port J8This port (J8) is located at the front of the Controller Board just behind the hinged door.It is provided so that a programmer can easily program the microprocessor from the frontof the SitePro Controller without removing it from the cabinet.

CIRCUIT ANALYSIS30 MM101271V1 R2A7.3.2.9 DecouplersDecoupling capacitors (Decouplers) are used to eliminate high-speed transient noise inhigh-speed digital circuits. There are many decoupling capacitors used on the ControllerBoard. These capacitors are connected between a source and ground. For example, onsheet 3 of Schematic Diagram WD-CB101069V1 there are two 3.3V decouplingcapacitors, C2 and C87.7.3.3 BackplaneThe Controller Board to Interconnect Board A1 (Backplane) connector circuits are shownon Schematic Diagram WD-CB101069V1, Sheets 4-7 and include:• Board Connections • I/O (1)• Serial I/O • I/O (2)7.3.3.1 Board ConnectionsSchematic Diagram WD-CB101069V1, Sheet 4 shows the single DIN96 connector, J7.This 96-pin connector has three layers of pins, J7A, J7B and J7C. Each layer consists of32 pins. J7B, Pins 1 and 32 are the MATE-DETECT-A and MATE DETECT-Bconnections. These two connections are used with the Board Insertion Detection circuit.Pins J7B; Pins 27 and 28 are the SCL and SDA connections. SCL and SDA make up theI2C bus. CPU I/O SIGNAL PROTECTION DIODES D27, D29 connected to SCL andSDA provide surge protection for the I2C bus.7.3.3.2 Serial I/ONumerous asynchronous and synchronous serial ports are brought to the InterconnectBoard (Backplane) from the microprocessor, Modem Board and QUART. Most serialports convert to standard RS-232 levels using RS-232 transceivers U13, U24, U30 &U36. Serial port U21 converts to RS-485 differential signal levels and supports amultidrop network. One microprocessor RS-232 port is used as a diagnostic or localprogramming port and is brought to RJ-11 connector J8 on the front of the board. Twoports from the QUART use BSL signaling.All Serial ports are designed for full-duplex 115.2 kbaud communications with theexception of the RS-485 port U21 from the microprocessor SCC. This port is a half-duplex HDLC port and supports speeds up to 2 Mbaud.U21 is a differential bus transceiver for bi-directional data communication on multiportbus transmission lines. This device combines a 3-state differential line driver and adifferential input line receiver. The driver and receiver have active-high and active-lowenables that are connected together externally to function as a direction control. Thedriver differential outputs and the receiver differential inputs are connected internally toform differential input/output I/O bus ports. These ports are designed to offer minimumloading to the bus when the driver is disabled or Vcc=0.BSL signaling is accomplished through two identical circuits consisting of hex invertingSchmitt Triggers U23A/U23B, inverter buffer drivers U35A/U35B, Field EffectTransistors (FET) Q3/Q4, NPN transistors Q9/Q10 and diodes D23/D25. Inputs to themicroprocessor from the Interconnect Board (backplane) are through diode D23/D25 tothe input of U23A/U23B. Schmitt Trigger U23A/U23B provides a well-defined output

CIRCUIT ANALYSISMM101271V1 R2A 31for an input to the base of NPN transistor Q9/Q10. Transistors Q9/Q10 are used toconvert the RX level from 5V to 3.3V. The output of Q9/Q10 (RXA/RXB) is applied at3.3V to the microprocessor. When the input (BKP-BSL0/BSL1) is high, diode D23/D25is reversed biased making the input to U23A/U23B high and the output on the collectorof Q9/Q10 also high. When the input is low, diode D23/D25 is forward biased and theinput to U23A/U23B is low. The output on the collector of Q9/Q10 is also low.Outputs from the microprocessor to the backplane are through inverter buffer driverU35A/U35B, and FET Q3/Q4. The output RXA/RXB from the QUART is applied to theinput of inverter circuit U35A/B35B. When this input to U35A/B35B is low, the output ishigh. This causes Q3/Q4 to conduct. Diode D32/D33 is forwarded biased and the outputto BKP-BSL0/BSL1 is low. Diode D32/D33 prevents loading the BSL when power isoff. When the input to U35A/U35B is high Q3/Q4 does not conduct and the output toBKP-BSL0/BSL1 is high. FET Q3/Q4 is powerful enough to drive 1k ohm loads on up to25 parallel connected shelves.7.3.3.3 I/OOther I/O’s are shown on Schematic Diagram WD-CB101069V1, Sheets 6 and 7. Inputsto the EPLD from the backplane consist of identical circuits for different inputs. Thesecircuits consist of inverter buffer driver circuits U18A thru F, Schmitt Triggers U22Bthru D and U23C thru F (Figure 5 - Input Circuits U18A thru F, U22B thru D and U23Cthru F). Identical circuits for different inputs also include inverter buffer driver circuitsU22A, E, F, U29D and U32B (Figure 6 - Input Circuits U22A, E, F, U29D and U32B).Figure 5 shows inputs using 74HC14's with diode coupling.

CIRCUIT ANALYSIS34 MM101271V1 R2A7.3.4 CPUThe Central Processing Unit (CPU) circuits, for the Controller Board, are shown onSchematic Diagram WD-CB101069V1, Sheets 8 & 9 and include:• Microprocessor • Microprocessor Support7.3.4.1 MicroprocessorMicroprocessor U94 is an MPC860P processor that has four SCC channels, two SMCchannels, plus a 100 Mbit Fast Ethernet Controller. One of the SCC channels is used as asecond ethernet port (10 Mbit) with all other SCC and SMC channels used as serial ports.This microprocessor runs at 59 MHz using a 29.4912 MHz clock input. This frequencywas selected for use by the baud rate generators to produce standard baud rates up to115.2 kbaud without error. The microprocessor external bus runs at half the speed of themicroprocessor (29.5 MHz).The microprocessor provides an internal real-time clock that is used to provide time-of-day information to the application software. The real time clock runs off of a 32.768 kHzcrystal. An external real-time clock is connected to the microprocessor through the 12Cbus. The microprocessor accesses the internal real-time clock much faster than theexternal one. Therefore, whenever the board powers up, the battery-backed external real-time clock is used to set the time of the internal real-time clock. Once the internal real-time clock is set, it will always be used while the board is powered.Four external interrupts are used in this design. The remaining unused three connect tothe EPLD for future use. Connecting them to the EPLD makes later modifications easier.The external interrupt signals are specified in the following table.Table 4 - External Processor Interrupt SignalsDEVICE IRQ(SPARE-EPLD) IRQ (NMI)QUART IRQ1MODEM DB DUAL-PORT RAM IRQ2(SPARE-EPLD) IRQ3ETHERNET 10/100 IRQ4ETHERNET 10 IRQ5(SPARE-EPLD) IRQ6All but one chip select are used in this design. The unused chip select is connected to theEPLD for future use. The microprocessor chip select signals are defined in the followingtable. 4 Microprocessor U9A and U9B are two parts of the same processor. This was done for drawing convenience.

The 8-bit data bus isconnected to the 32-bit processor data bus via an 8-bit transceiver. The output enable forthe transceiver is controlled by ANDing all 8-bit chip selects together inside the EPLD.7.3.4.2 Microprocessor SupportThe microprocessor support as shown on Schematic Diagram WP-CB101069V1, Sheet 9includes:• BDM Debug Port Connector • Silicon Serial Number• Power-On Reset Configuration • KAPWR Switch• 32 kHz Crystal • 8-Bit Bus Transceiver• VDDSYN Filter • MICTOR Logic Analyzer ConnectorsBDM Debug Port ConnectorFor debug and development, microprocessor U9A provides a dedicated serial port (BDM)for connecting a debugger/emulator. A debugger/emulator connected to this port allows aprogrammer to read/write registers and external peripherals, control program execution,etc. Many debuggers also have built-in capability to program on-board flash through thisport. These serial port pins are brought to 10-pin header J1 using the standard BDMpinout.Power-ON Reset ConfigurationThe Power-On Reset Configuration consists of four octal buffer/drivers U6A, U6B, U8Aand U8B with 3-state outputs. This circuit ensures that at Power-On all circuits are resetto the starting state. Inputs to these circuits are through 10K BUS8 resistor networks RN7and RN10. The outputs tie into bus D[0.31]. Each package is organized as two 4-bit linedrivers with separate output-enable (OE) inputs. These inputs are tied together andconnect to RESET-N. When RESET-N is low, data passes from A inputs to Y outputs.When RESET-N is high, the outputs are in the high-impedance state. This circuit imposes 5 UPMB is only required if the system makes use of the BUSY_N signal coming from the dual port memory. If BUSY_N isnot used, then a GPCM machine can be used for this chip select.

Themicroprocessor reads the data bus state just before RESET goes inactive (high) and usesthe result for start-up initialization.At power up, the MPC860 samples the data bus and the MODCK bits to obtain theHardware Configuration Word and clock setup parameters respectively. The SiteProhardware configures these as follows:Data bus 0x017A 0000MODCK1, 2 1,0This results in the following configuration:Internal arbitrationInterrupt vector location 0xFFF0 0000Boot Port size is 32 bits.IMMR is at 0xFF00_0000.Debug Pin Configuration is as follows: VFLS[01], VF0, VF1, STS, AT1, AT2, AT0,AT3, OP3.Debug Port Pin Configuration is DSCK, DSD1, DSD0, PTR1, TCK, TD1 and TD0.External Bus speed set to ½ system clock.Pitrtc connected to extclk and div by 4, pitclk = 32.768/4 = 8192 HzSys clk connected to EXTCLK vco factor is 1, sysclk = 29.4912 MHz32 kHz CrystalThis crystal circuit consists of crystal package Y3, resistors R90 and R98, capacitors C49and C63. This circuits connects to microprocessor U9A between pins N1 (EXTAL) andP1 (XTAL) and produces an oscillator frequency of 32.768kHz to drive the real-timeclock.29 MHz ClockThe 29 MHz Clock consists of oscillator circuit Y2 and resistors R82 and R105. Thiscircuit produces the oscillator frequency of 29.4912 MHz and connects to microprocessorU9A at N2 (EXTCLK).VDDSYN FilterThis circuit consists of inductor L1 and capacitors C50 and C57. It filters the 3.3V supplyto the system Phase-Locked-Loop (PLL) circuitry on microprocessor U9A. The PLLmultiplies the EXTCLK by an integer factor to provide a bus clock.Silicon Serial NumberA unique 64-bit electronic Serial Number chip U3 is used to store the board identificationnumber. This chip has a 1-bit serial port, which interfaces to microprocessor U9 throughan I/O port. In addition, four bits of hardware identification are made available to U9through I/O ports. The Hardware ID is changed by selectively populating a bank ofresistors.

CIRCUIT ANALYSISMM101271V1 R2A 37Real Time Clock (RTC)A battery backed up Real Time Clock, U43, is provided to retain the elapsed time evenwith power off. U43 can be read or written via the I2C bus. The slave address for U43 isD0 hex. Accurate timing is maintained by 32.768kHz crystal Y5.Processor U9 has an internal real time clock, however it consumes too much power toallow battery back up. Therefore the real time is read from U43 via the I2C bus at powerup and stored in the processors RTC. This is a fairly slow process. Afterward, theprocessor can quickly determine the time by reading the internal RTC. Timing for theprocessor RTC is provided by 32.768kHz crystal Y3.KAPWRThe Keep-Alive-PoWeR (KAPWR) circuit consists of 0-ohm resistor R196 and is usedfor the "real time" clock on the microprocessor (860). KAPWR is not powered whenpower is off. This circuit applies 3.3V supply to U9B, Pin R1 (KAPWR).8-Bit Bus TransceiverThis circuit consists of 8-Bit Bus Transceiver U19 and resistor network RN15. The 8-BitBus connects to the microprocessor through 8-Bit Bus Transceiver U19. The outputenable OE for the transceiver is controlled by ANDing all 8-bit chip selects togetherinside EPLD U27. This transceiver drives the data bus for all 8-bit devices.MICTOR Logic Analyzer ConnectorsThese connections consist of J3, J5 and J6. These connectors are for softwaredevelopment and are not present in production units.7.3.5 SitePro Modem Board ConnectorThe SitePro Modem Board connector circuits for the Controller Board are shown onSchematic Diagram WD-CB101069V1, Sheet 10 and include:• QUICC Connector (J9) • I/O Connector (J2)7.3.5.1 QUIC Connector (J9)The QUICC (J9) connector contains the microprocessor interface (Refer to the ModemBoard Section).7.3.5.2 I/O Connector (J2)The I/O (J2) connector has miscellaneous I/O to/from the EPLD or Interconnect Board(Refer to the Modem Board Section).7.3.6 Electrically Programmable Logic Device (EPLD)The EPLD circuit for the Controller Board is shown on Schematic Diagram WD-CB101069V1, Sheet 11. Also, refer to the EPLD Drawings listed in the Table ofContents.

CIRCUIT ANALYSIS38 MM101271V1 R2AAccess to various board inputs/outputs is made available through ElectronicallyProgrammable Logic Device (EPLD) U27. The EPLD contains numerous read/writelatches with a simple 8-bit interface to the microprocessor.The EPLD is in-circuit programmable via the JTAG port using an Altera Byte-blastercable. A 10-Pin header J10 is made available for this purpose. The EPLD JTAG port isalso brought to microprocessor I/O pins to allow the microprocessor to load the EPLDconfiguration.The JTAG port is routed to Modem board (A2-A1). This allows a future modem board tobe designed with an Altera EPLD. If that future EPLD modem board is used, resistorR187 (0 ohms) must be removed from the board.In addition to being an interface to the discrete I/O, the EPLD also divides clocks andprovides the output enable logic for the 8-bit data bus transceiver. It also derives the FSLpulse stream from RFTXDAT and RFTXCLK in the Control Channel mode.7.3.7 Ethernet PortsThere are two Ethernet Port circuits for the Controller Board shown on SchematicDiagram WD-CB101069V1, Sheets 12 & 13 as:• 10 Base-T (10 Mbit PHY) • 10/100 Base-T (10/100 Mbit PHY)The 10/100 Mbit port (10/100 Base-T Transceiver U5) uses the Fast Ethernet Controller(FEC) inside the microprocessor and supports full duplex (10/100 Base-T). The 10 Mbitport (10 Base-T Transceiver U12) uses SCC1 and only supports half-duplex (10 Base-T).The ethernet physical layer transceivers are the same for both ports, but the 10/100 Mbitport uses a Media Independent Interface (MII), whereas the 10 Mbit uses a “7-wire”interface. The ethernet transceivers support 10/100 Base-T with full auto-negotiationcapability, while the 10 Mbit port only advertises 10 Mbit capability.The RJ-45 ethernet connectors are actually located on Interconnect Board A1. Theethernet physical layer chips and transformers reside on the Controller Board with theethernet differential RX/TX signals brought to the RJ-45 connectors through theInterconnect Board connector. A single LINK OK status LED is provided for eachethernet port on the front of the Controller Board.The 10Mbit Ethernet port uses the “7-wire” interface to connect the Ethernet physicaltransceiver to the microprocessor SCC1 serial channel. When SCC1 is in Ethernet mode,the SCC pins have different functions (refer to the following table).Table 6 - 10 Mbit Ethernet ConnectionsSCC ETHERNET SIGNAL SCC PIN NAME PHY SIGNALTX TXD1 10TXDTENA RTS1 10TXENTCLK CLKx 10TXCLKCLSN CTS1 10COLRENA CD1 10CRSRX RXD1 10RXDTCLK CLKx 10RXCLK

The I2C Bus circuits, for the Controller Board, are shown on Schematic DiagramWD-CB101069V1, Sheet 14. These circuits consist of Personality EEPROM U14 and 8-bit I/O expanders for the I2C bus U15 and U26.EEPROM U14 provides 16k of non-volatile data storage. EEPROM U14 is organized as16kx8 and is accessible via the I2C port of microprocessor U9.Serial EEPROM U14 has a write protect pin. It is active high and has an external pull-up.To write to U14, port PB23 on the microprocessor is defined as an output and driven low.To write protect the EEPROM after writing to it, port PB23 is defined as an input and thepull-up activates the write protect signal.Several peripherals are available to the microprocessor through the I2C Bus. In additionto a 16kbyte EEPROM, there is an 8-bit writable latch for driving 4 LEDs and an 8-bitreadable latch for reading the status of an 8-bit DIP switch. The I2C bus is also brought tothe Interconnect Board for accessing other off-board peripherals (i.e. LED display).

These two chips have 4 Mbytes of flash memory with theability of expansion up to 8 Mbytes. One or more flash sectors contain "bootloader" code,which contains enough functionality to load and store new versions of application code.7.3.9.3 Quad UARTThe QUART circuit for the Controller Board is shown on Schematic Diagram WD-CB101069V1, Sheet 17.Quad Universal Asynchronous Receiver-Transmitter (QUART) U28 is used to handleasynchronous serial data communication.The serial port is a general-purpose interface that conforms to the RecommendedStandard–232C (RS-232C) and can be used to interface with almost any type of device(modem, mouse and serial printer, etc.).Quad UART U28 provides four additional serial ports for microprocessor U9. U28 ispowered by 3.3V, which forces the microprocessor interface to be asynchronous and runat 14.75 MHz, the microprocessor bus clock divided by 2 inside the EPLD. Thecommunication clock input is 3.6864 MHz, the microprocessor bus clock divided by 8inside the EPDL. None of the I/O ports of the QUART are used at this time.The QUART uses two chip selects, CS2 and CS3. Chip select CS2 is used whenaccessing the QUART registers. Chip select CS3 is used after an interrupt to read theinterrupt vector.

CIRCUIT ANALYSISMM101271V1 R2A 417.4 SitePro MODEM BOARDThe SitePro Modem Board contains three synchronous serial ports (modems) and a localmicroprocessor. This board plugs into the Controller Board using two connectors,QUICC (J9) and I/O (J2). Refer to Figure 9 - Site Pro Modem Board Block Diagram.The microprocessor interface is a simple 8-bit bus port with two separate chip selects.One chip select controls access to an 8k x 8 dual port RAM. The other chip selectcontrols access to the Modem Board microprocessor local code memory. The ControllerBoard microprocessor loads the Modem Board local code memory with code beforereleasing the Modem Board reset. The Modem Board microprocessor runs from a 14.7MHz clock generated by dividing down the 29.5 MHz Controller Board microprocessoroutput clock inside the EPLD.Circuits for the SitePro Modem Board, are shown on Schematic Diagram WD-CB101074V1, Sheet 1. The Outline Diagram is shown on AD-CB101074V1.Modem Board CB101074V1 mounts on the Controller Board and exists primarily tosupport Modem chips, U9, U10, and U11. These modems process 9600 baud serialsynchronous receive and transmit data from the RF path (U9), the Phone Line (PL) path(U10) and the Voted Digital Interconnect (VDI) path (U11).Microprocessor U1, a Dallas 80C323, controls the three modem chips, generates transmitdata, and processes receive data for use by the system.The microprocessor communicates with the QUICC processor on the Controller Boardvia Dual Port RAM U3.There is no non-volatile memory on the Modem Board. Code is loaded into Code RAM(U2) via an interface from the QUICC processor.The microprocessor circuitry on the Modem Board operates from a 3.3V supply. TheModem chips, however, require 5V. Thus a 3.3V to 5V conversion (U6) is needed for allsignals to the Modem chips.7.4.1 ModemsEach Modem chip interfaces to the 80C323 microprocessor via an 8-bit bi-directionaladdress/data bus, and Chip Select (CS/), Read (RD/), Write (WR/), ALE, and Interrupt(INT/) signals.During transmit the microprocessor writes data to the Modem as requested by the Modeminterrupt. The Modem converts the data to a 9600-baud synchronous serial data stream.During receive the Modem chip receives the 9600-baud synchronous serial data streamand interrupts the 80C323 microprocessor whenever it has a complete byte to transfer.The modem must also acquire bit sync and word sync from the data stream.7.4.2 3.3V/5V InterfaceBecause the Modems require a 5V supply, and the microprocessor is on a 3.3V supply, itis necessary to convert the voltage of signals passing between them. This is done by U6,an IDT74FCT164245 3.3V/5V converter. Both output enable and direction can becontrolled for the two 8-bit sections of this IC.

CIRCUIT ANALYSISMM101271V1 R2A 43In this case, the outputs are always enabled, so the OE/ pins are tied low. Section 1 isused for signals which only go from the microprocessor to the Modems, so Pin 1 (1DIR)is tied high. Section 2 is used for the bi-directional bus. Pin 24 (2DIR) is driven by logicwhich sets the direction from microprocessor to Modems (high) most of the time. Onlyduring a read of one of the modems is the direction reversed (low).7.4.3 MicroprocessorThe 80C323 microprocessor is a 3.3V version of the Dallas Speedy micro, an 80C32derivative. It operates on a 14.7462 MHz. clock, which is convenient for generatingstandard baud rates. It interfaces with the Modems, Code RAM, Dual Port RAM, andData RAM via standard address and data busses.The microprocessor has 2 asynchronous serial ports (TXD0/RXD0 and TXD1/RXD1)which may be used in the SitePro Controller system for diagnostics. Both ports areavailable on the rear of the SitePro Controller shelf.Six bits of 80C323 microprocessor I/O are used in a SitePro Controller configuration.WALCLK, WAL1, WAL2, and HSACQCTL are outputs, while LSRX and MODFSL areinputs.The microprocessor has only two level sensitive interrupts, INT0/ and INT1/. The first,INT0/, is used for all Modem interrupts. The second, INT1/, is used for interrupts fromthe Dual Port Ram.Since it is still necessary to distinguish between the three Modem interrupts, RFINT/ andPLINT/ are brought to I/O pins so the microprocessor can easily determine whichModem is interrupting. i.e. If a Modem interrupt occurs, the microprocessor looks at thetwo pins. If either or both are low, the corresponding interrupts are serviced. If neither islow, the VDI interrupt is serviced.The 80C323 (U1) uses standard Intel multiplexed address/data bussing. During the firsthalf of the bus cycle, U7 latches the lower 8 bits of address under the control of ALE.Address decoder U5 generates the Chip Selects for the three modems and the Dual PortRAM using signals RD/, WR/, A13, A14, and A15.Table 9 - Memory MapMEMORY MAPDevice Range Addressable SizeCode RAM 0-FFFF 64K BytesDual Port RAM 0-1FFF 8K BytesData RAM 8000-FFFF 32K BytesRF Modem 2000-2003 4 BytesPL Modem 4000-4003 4 BytesVDI Modem 6000-6003 4 Bytes7.4.4 Code MemoryCode is stored in 128K byte RAM U2.

CIRCUIT ANALYSIS44 MM101271V1 R2Awill not try to access U2 at the same time causing bus contentions. During loading, bustransceivers U12 (address bus) and U13 (data bus) are turned on. They are held inactiveat all other times by the same RESETIN/ signal.The QUICC controls Code memory access through signals RESETIN/, R/WL/,CODECS/ and CODE_A16. While RESETIN/ is held low, the QUICC can write or readU2. CODE_A16 can be used to control which 64K byte half of U2 is used. Thus, forinstance, Control Channel code could be stored in one half and working channel code inthe other. The switch is performed, while the 80C323 is held at reset, so it is entirelytransparent to the 80C323.When RESETIN/ is high, the bus transceivers U12 and U13 are off and the 80C323controls the bus.7.4.5 Data MemoryData is stored in 128K byte RAM U4, however, only 32K is used. Chip select is A15/,thus the RAM is addressed in the upper half of memory space.7.4.6 Dual Port RamDual Port RAM U3, an IDT70V05 8K byte device, is the communication link betweenQUICC and 80C323 during normal operation. Either microprocessor can read or writeany location in the RAM. Protocols must be established in software to avoid contention.The QUICC can interrupt the 80C323 by writing to Address 1FFF. This causes interruptline INTR/ to go low. It is cleared by a read of the same address by the 80C323.Likewise, the 80C323 can interrupt the QUICC by writing to address 1FFE, which causesa QUICC interrupt on line INTL/.The 80C323 accesses the DPR via its address and data busses using signals DPRCS/,RD/, WR/, and INTl/.The QUICC accesses the DPR via its address and data busses using correspondingsignals CEL/, R/WL/, OEL/, and INTL/.7.4.7 Troubleshooting AidsSeveral signals are available on diagnostic connector J3 for troubleshooting purposes.Also probe points are provided for GND, 5V, and 3.3V.7.5 ROCKWELL MODEM INTERFACE CARD (A3)The SitePro Controller shelf uses Rockwell Modem Interface Card ROA 117 2247/1 andRockwell Modem Assembly, RYTUA 921 01/1.

High pass filter U16 isdriven by a 3.125 kHzCLK on Pin 16 (CLK) and is a 4th order Butterworth filter. Itprovides -3 dB rolloff @ 50 Hz and -35 dB rolloff @ 18 Hz (Table 16 - Low Speed DataDecode Filter Response). The output of U16, monitored at TP16, is applied to the inputof low pass filter U14. Low pass filter U14 is synchronized by a 25 kHz clock applied toPin 3 (CLK) and is an 8th order elliptic filter. It is flat to 250 Hz and provides more than -40 dB rolloff @ 300 Hz.The output of U14, monitored at TP17, is applied to the input of buffer/amplifier U28Athough 0 ohm resistors R61 and R61.

MovingR67 in and out of the circuit adjusts the input time constant to U12B, Pin 6.Voltage comparator U12B provides a square wave output that swings from +12 to -12volts, monitored at TP14. This output is applied through resistor R58 to the base of NPNtransistor Q1. Transistor Q1 interfaces the limited signal LSIN to the Controller Board.Table 16 - Low Speed Data Decode Filter ResponseFREQUENCY RESPONSE100 Hz 0 dB (ref)50 Hz -3 dB ± 1dB18 Hz -35 dB ± 3 dB250 Hz -0 dB ± 1dB300 Hz <-40 dBHigh Speed SlicerThe High Speed slicer circuit converts 9600 baud noisy received data to hard 1's and 0's,producing a +5Volt square wave at the output of U33A. This output is controlled by theHSACQCTL0 and HSACQCTL1 inputs to U31, Pins 1 (A0) and 14 (A1) respectively.HSACQCTL0 is controlled directly by microprocessor 80C323 rapidly controlling thereceive acquisition rate by adjusting the input time constant to U33A. The Time Constant(TC) is adjusted to provide a fast TC to follow the initial frequency variation of thetransmitting radio, then a slow TC to better slice the data after the frequency becomesstable.The TC is adjusted by selecting a resistor to connect in the negative input terminal ofU33A (Pin 2).

Low-speed data is a 150 bit per second data stream generated bythe microcomputer and used to produce subaudible data on the voice audio.

CIRCUIT ANALYSISMM101271V1 R2A 51Low-Speed Data is generated by microcomputer U1 on the Modem Board through EPLDU27, Pins 81 and 80, Walsh Bit 1 and Walsh Bit 2 respectively. For low-speed data, thetwo Walsh bits are scaled by resistors R91 and R95 and summed through analog switchU22. The output of U22, Pin 1 (D) connects through operational amplifier U19A andbuffer/follower U19B to the input of the low-speed-data encode filter U20. Operationalamplifier U19A produces a loss of -9 dB at TP23. The output of buffer U19B, monitoredat TP22 connects to the input of low-pass filter U20, Pin 14 (IN). Low pass filter U20 issynchronized by a 25 kHz clock applied to Pin 3 (CLK) and is an 8th order elliptic filter.For the frequency response refer to the following table.Table 18 - Low-Speed Data Encode Filter ResponseFREQUENCY RESPONSE100 Hz 0 dB (ref)5 Hz +1 dB ± 2dB150 Hz -1.5 dB ± 1 dB250 Hz -4 dB ± 1dB300 Hz <-40 dBThe output of this filter, monitored at TP21, connects through 0 ohm resistor R84 to theinput of operational amplifier U17A, Pin 3. U17A provides a gain of 2:1. LSDTXconnects to J1B, Pin 21 through Interconnect Board A1 to the EDACS connector J12, Pin23 (LSDTXMOD). This provides the low frequency Channel Guard modulation input tothe base station transmitter.7.6.8 Simulcast Control CircuitsSimulcast control circuits, consisting of RS-232 and RS-422 drivers, convert (RS-232 -TTL - RS-422) and buffer control signals coming from SitePro Controller Board A2.Refer to the second page of Figure 11 - Analog Board Block Diagram. These signals arepassed through Simulcast connector J13, on Interconnect Board A1, and connect to theSimulcast cross connect panel. Likewise, RS-422 drivers convert (RS-422 to TTL) andbuffer signals coming from the cross connect panel, passing through A1 and going toSitePro Controller Board A2.A Simulcast "bypass" control signal, when low, forces the Simulcast site to operate in anon-Simulcast mode and is driven by Simulcast control equipment. The active lowbypass control line, BYPASS, originates at the Simulcast control equipment, and is usedto re-route audio paths at the SitePro interface module located in a station interface panel.It also serves to re-route 9600 BPS data, 150 BPS data, A/D control line and the PTTcontrol line, all of which are directed back to the SitePro Controller Board.Control SignalsRS-232 Drivers/Receivers U24 and Quad RS-422 Line Driver U25 converts and bufferssignals coming from the SitePro Controller Board and going to the Simulcast crossconnect panel.

TXAUDIO L connects though K1 to TXV R. Also, RX AUDIO H connects through relayK2 to RXV T. TX AUDIO H connects through K2 to TXV T.When the BYPASS signal goes low, forward biasing diode D15, relay drivers U27 causerelays K1 and K2 to activate. This action places the Simulcast System in the Bypassmode. RX AUDIO L now connects through K1 to TX AUDIO L. Likewise, RX AUDIOH connects through K2 to TX AUDIO H, returning the audio back to the station.

TROUBLESHOOTING64 MM101271V1 R2A9.4 FIELD TROUBLESHOOTING GUIDE9.4.1 SitePro Controller BoardThis guide assumes the Controller board is in a SitePro shelf on a bench, not connected toa station, but with 13.8V power applied to J7 of the shelf. It is also assumed that‘FactoryTest’ software resides on the Controller. Modem board test program ‘SIMON’ isalso needed for some of the tests. In most cases, the shelf top cover must be removed.See the Shelf Test Procedure for setup information and some information on FactoryTest.Set up two terminal emulators as described in the Shelf test.This is not a detailed test procedure. It is intended for use in service shops by technicianshaving a high degree of expertise in troubleshooting electronic circuitry. Some circuitscannot be tested at the shelf level.9.4.1.1 REFERENCE DOCUMENTSWD-CB101069V1 - Schematic DiagramTS-CB101069V1 - Test SpecAD-CB101069V1 - Assembly DrawingBlock Diagrams of Controller Board and SitePro Modem Board9.4.1.2 BOARD WILL NOT RUN i.e. FACTORY TEST DOESN’T COME UPProcedure:After 3 PNGs appear on the terminal, wait about 10 seconds or until ‘F R1A01’ or laterversion number appears on the display.ENTER should put the FactoryTest software into Command mode. ‘q’ then ENTER takesit to Non-menu mode, then ‘m’ followed by ENTER should produce the test menu. If noresponse, turn power off then on and retry. If Boot/Loader comes up (> prompt), seriallyload Factory Test.Troubleshooting information:Check 5V at TP6 and 3.3V at TP5.If no voltage, check hot swap controller U37. U32-2 (ON) should be 5V, Mate-detect Aand B should both be grounded. U37-5 (FB) should be 1.3V. U37-6 (GATE) should beabout 16V.If 5V is not seen on U42-2, then 555 timer U40 may be holding the ON pin low exceptfor momentary intervals every second or so.There may be a problem in the serial port SMC1, which is used to interface to the testsystem through the diagnostic connector J8 on the front of the board. This is a normalserial port of the 860 processor. The J8 interface is RS232, which is converted to 3.3Vlevels to the processor. SMC1TX originates from U1 (not accessible) at 3.3V level anddrives RS232 converter U36-17. U36-12 drives J8-2 at RS232 levels. Input from theterminal comes in at RS232 levels to J8-1, which is fed to U24-5 where it is converted to3.3V levels at U24-18 and goes to SMC1RX on U1 (not accessible).

Test with aknown good Modem board to isolate the problem to the Controller or the Modem.9.4.2.2 DUAL PORT RAM TESTProcedure:Execute Factory Test test 4, subtest 3.Troubleshooting information:Failure indicates a problem communicating with U3 on the Modem Board.IF MODEM BOARD IS BADCheck the Dual Port RAM U3 and Code RAM U2The processor should be held reset during these tests. U1-10 should be HI (3.3V) toreset.IF CONTROLLER IS BADCheck 14.7456MHz on J9-19.Check Data bus activity on J9-1,2,3,4,33,34,35,36Check address bus activity on J9-5 thru12, and 25 thru 32.Check that DPR Chip Select is occurring on J9-15 during DPR test.Check that Code RAM Chip Select is occurring on J9-14 during Code RAM test.Check that RESET is HI (3.3V) on U1-10 during Code RAM test.9.4.2.3 INTERRUPT FEATUREProcedure:Use FactoryTest test 4, subtest 1 to load ‘DCTEST.HEX’. Then execute FactoryTest test4, subtests 4 and 5.

TROUBLESHOOTING66 MM101271V1 R2ATroubleshooting information:Was ‘DCTEST’ loaded into the Modem daughter board?Check DPR U3 on Modem Daughter Board. Pin 38 Interrupts the 80C323 on the ModemBoard. Pin 43 interrupts the 860. This test is an interaction between the Modem Boardand the Controller Board so testing with one known good board can isolate the problem.9.4.3 Modem Board Tests Using Simon9.4.3.1 LOAD SIMONProcedure:Use FactoryTest test 4, subtest 1 to load ‘SIMON.HEX’.Troubleshooting information:If SIMON loads properly, you will hear a beep or see the SIMON turn-on banner appearon the terminal connected to 80C323 Port 0.Failure to load code in the Modem board (applies to DCTEST also) could be due toproblems with Code RAM U2 and associated logic U17 and U18. Processor U1 must beheld reset (U1-10=3.3V) during a code load. It is unreset when ENTER is sent to FactoryTest after a download.9.4.3.2 TEST DPR FROM THE MODEM SIDEProcedure:Execute SIMON Command ‘TMX 0-1FFD’.Troubleshooting information:Assuming SIMON loaded and is running, there must be a problem with DPR U3 or theMicroprocessor (U1)interface to it. Note: Use terminal 2 for SIMON commands.9.4.3.3 TEST MODEM DATA SRAMProcedure:Execute SIMON Command ‘TMX 8000-FFFF’.Troubleshooting information:If SIMON is running, U4 is indicated.9.4.3.4 MODEM BER TEST ON RF MODEMProcedure:This is the same test as the shelf RF loopback test. Execute SIMON Command BERDE-02=1. Correct result is no errors and checksum=027C11.Troubleshooting information:SIMON causes a data stream to be generated in RF Modem U9 at U9-21 (RFTXDAT).This data goes to the Controller Board on J2-30 where it enters the PLD at U27-122

TROUBLESHOOTINGMM101271V1 R2A 67(RFTXD). It exits on U27-38 (RFTXDAT), is buffered and inverted by U29F, enteringon U29-13, exiting on U29-12. It exits the Board on J7-C23.At the rear of the shelf, RFTXDAT is looped back into the Controller board on J7-C26(RFRXDAT_FROM_SLICER). This signal is buffered and inverted by U29D, enteringon U29-9, exiting on U29-8, which drives into the PLD U27-53. It exits the PLD on U27-99 (RFRXD). This goes to the Modem Board on J2-7. On the Modem Board, it goes toU9-19 completing the loop.Refer to RF Loop Test Block Diagram in the instruction book.This test may fail due to problems in the microprocessor U1 interface to the Modem ICU9. This includes 3V/5V converter U6, U21, U23, U16C and perhaps address decoderU5 or U16A. Many negative going interrupt pulses should be seen on U9-24. Check R11.9.4.3.5 MODEM BER TEST ON PL MODEMProcedure:This is the same as the shelf PL loopback test. Reset the Modem Board. SIMONCommands are MDS1 then BERDE-01=1. Correct result is no errors andchecksum=027C11.Troubleshooting information:After running the BER test on the RF Modem (above), SIMON code requires a resetbefore running the BER test on the Phone Line Modem. This can be accomplished byusing FactoryTest to execute test 4, subtest 3 (Dual Port RAM test). This will reset theProcessor then unreset it without affecting loaded code.SIMON causes a data stream to be generated in PL Modem U10 at U10-21 (PLTXDAT).This data goes to the Controller Board on J2-9 where it enters the PLD at U27-31(PLTXD). It exits on U27-23 (PLTXDAT), is buffered, inverted and converted to RS232levels by U30, entering on U30-7, exiting on U30-2. It exits the Board on J7-B19.Data is passed through the Rockwell Modem then, at the rear of the shelf, PLTXDAT islooped back through the Rockwell Modem and into the Controller board on J7-B21(PLRXDAT). This signal is buffered, inverted and converted back to TTL levels by U30,entering on U30-9, exiting on U30-8, which drives into the PLD U27-25. It exits the PLDon U27-34 (PLRXD). This goes to the Modem Board on J2-29. On the Modem Board, itgoes to U10-19 completing the loop.Refer to PL Loop Test Block Diagram in the instruction book.This test may fail due to problems in the microprocessor U1 interface to the Modem ICU10. This includes 3V/5V converter U6, U21, U23, U16C and perhaps address decoderU5 or U16A. Many negative going interrupt pulses should be seen on U10-24. CheckR129.4.3.6 TEST LSDINProcedure:Apply 100Hz 1VPP sine wave to J12-7. This should produce a 0 to 5V 100Hz squarewave at Controller Board connector J7-C10.

TROUBLESHOOTINGMM101271V1 R2A 699.4.3.9 ETHERNET TESTProcedure:Execute FactoryTest test 5, subtests 1 and 2.Troubleshooting information:The FEC is the 10/100 Base-T Ethernet port originating in the 860 MII port whichinterfaces to Network PHY device U5. U5 drives transformer T1 which drives off theboard to Ethernet Port 0. Tx+ and Tx- are on pins J7-A2 and J7-A3. Rx+ and Rx- are onpins J7-A5 and J7-A6.SCC1 is the 10 Base-T Ethernet port originating in the 860 SCC1 port which interfaces toNetwork PHY device U12. U12 drives transformer T2, which drives off the board toEthernet Port 1. Tx+ and Tx- are on pins J7-A8 and J7-A9. Rx+ and Rx- are on pins J7-A11 and J7-A12.Three tests are run on each Ethernet port.The first test performs a loopback test entirely inside the 860 processor. It should neverfail.The second test performs a loopback test inside the PHY chip. Failure indicates aproblem with the PHY chip or the connections from the 860 to the PHY.The third test performs an external loopback test with the TX (+ and -) looped back toRX (+ and -) using a loopback plug on the rear of the shelf. These connections must bevery short. If the first 2 tests pass, failure indicates problems with the transformer or theconnections from the PHY to the transformer, or the loopback plug.9.4.3.10 LED TESTProcedure:Execute FactoryTest test 6.Troubleshooting information:I2C bus may be shorted.

It enters thePLD on U27-82 where it can be read by the 860 processor.9.4.3.27 PHASE LOCKED LOOP TEST AND TXC_MISSING_ALARM TESTProcedure:Use a Function Generator to produce a 0V to 5V 9600Hz square wave. Apply this acrossJ13-13 & 14 (9.6REF+ and -), with the ground side connected to J13-14.Execute FactoryTest test 14, subtest 1. Ignore the first line of the on screen instructionssince the input is applied differently. Use a dual trace scope as described to check for twosignals in phase. RFTXCLK is also seen at J11-14.Troubleshooting information:This test uses PLL IC U16 to phase lock the RFTXCLK used by the RF Modem U9 onthe SitePro Modem Board to an external reference signal 9.6REFIN. The PLL chipgenerates an 11.0592 MHz clock slaved to the external reference. In the PLD, this clockis switched to the Modem board instead of the 11.0592 MHz. oscillator clock. ModemBoard IC U9 divides the 11.0592 MHz back down to 9.6kHz (RFTXCLK) which isphased locked by the PLL U16. Both the reference and the feedback signals are switchedto the PLL inside the PLD.A Modem board must be present for this test and it must not be held reset. The Modemboard is normally held reset by the Controller until it is explicitly unreset. It can beunreset by loading code such as SIMON to it. It can also be unreset by executing FactoryTest 4, subtest 3, (Test Dual Port RAM).9.6REFIN enters the Controller board at TTL levels on J7-C15. It is buffered andinverted by U22F, entering in U22-13, exiting on U22-12. It enters the PLD on U27-69.RFTXCLK is derived from the 11.0592 MHz clock on the Modem Board by U9, exitingon U9-27. It is routed to the Controller board through J2-8 (Modem board) whichconnects to Controller Board J2-8. It enters the PLD on U27-128.If the loop fails to lock, one or both signals 9.6REFIN or RFTXCLK may not be gettingto the PLL U16. U16 or some of the associated components may be wrong, misoriented

TROUBLESHOOTING78 MM101271V1 R2Aor missing. Use a known good Modem board. Check for 11.0592 MHz clock at ModemBoard U9-16.Procedure:Instead of following the on screen directions, observe TXC_MISSING_ALARM at J13-18. The test requires an external pullup resistor.Remove the 9.6REF signal. TXC_MISSING_ALARM should go high.Troubleshooting information:TXC_MISSING_ALARM is generated inside the PLD if 9.6REFIN is missing.9.6REFIN must get to the PLD via the path described above. TheTXC_MISSING_ALARM signal exits the PLD on U27-62. It is buffered and inverted byU35D, entering on U35-9, exiting U35-8.9.4.3.28 TEST PLTXCLKProcedure:Observe PLTXCLK (9600Hz, RS232) at J14A-4 on the rear of the shelf.Troubleshooting information:PLTXCLK is generated on the Modem Board at U10-27, and is inverted by U24 beforeexiting the Modem Board on J2-28. It enters the PLD on U27-32. It is also buffered,inverted, and converted to RS232 levels by U30, entering at U30-6, exiting U30-3. Itexits the Controller Board on J7-B20.A working Modem board must be present and not reset for this test.9.4.3.29 TEST VDITXCLKProcedure:Observe VDITXCLK (9600Hz, RS232) at J14B-4 on the rear of the shelf.Troubleshooting information:This test checks the path of VDITXCLK. It is generated on the Modem Board at U11-27,and is inverted by U25 before exiting the Modem Board on J2-11. It is buffered, inverted,and converted to RS232 levels by U30, entering at U30-21, exiting U30-28. It exits theController Board on J7-C20.A working Modem board must be present and not reset for this test.9.4.3.30 FSL OUTPUT TESTProcedure:Execute FactoryTest test 15Observe the FSL output at J4C-4 on the rear of the shelf.Troubleshooting information:The FSL signal is a series of negative going 12V to 0V pulses occurring every 30ms and2.5ms wide.The FSL output signal is generated in the PLD using RFTXCLK (tested above) from the

TROUBLESHOOTINGMM101271V1 R2A 79Modem Board. A working Modem board must be present and not reset for this test.The FSL signal exits the PLD at U27-113. It is buffered and inverted by U33, entering atU33-1, exiting U33-2 which drives FET driver Q2. The FET drives a +12V to 0V signalto J7-C30. The FSL output is capable of driving a 50 ohm load resistor pulled to +12V.9.4.3.31 EEPROM VERIFY TESTProcedure:After turning power off for a few seconds, then back on, execute FactoryTest test 8,subtest 2.Troubleshooting information:If other I2C devices (LEDs, dipswitch) are working, failure of this test indicates aproblem with U14. This test is run after power is turned off and back on. FactoryTest test8, subtest 1 must have been run previously. The EEPROM should retain its data withpower off.9.4.4 Analog BoardThis guide assumes the Analog board is in a SitePro shelf on a bench, not connected to astation, but with +13.8VDC power applied to J7 of the shelf. It is also assumed that‘FactoryTest’ software resides on the Controller board to provide control of the Analogboard. Modem board test program ‘SIMON’ is also needed for some of the tests. TwoTerminal emulators are needed. See shelf test.This is not a detailed test procedure.

The same signal should be seen at TP13. The signal is then sliced by comparatorU33A and a squared wave (0 to 5V) should be seen at RFRXDAT. Bias on U33-2 isaround 2.5V. Problems with U31 can affect the bias.

The frequency response is measured at TP18 before going tononlinear circuits. U12B is a slicer, which converts the waveform to a square signal atTP14. Q1 interfaces the squared waveform to a microprocessor on another board. Notethat a 10K pullup to +5V is needed on LSIN to see the 0 to 5V output.

It then goes through buffer U19B (seen at TP22). Thenthrough low pass filter U20 (seen at TP21) then through final amplifier/buffer U17A.Filtered output is seen at LSDTX.Frequency response at LSDTX is entirely determined by U20 and associated componentsand by the 25kHz clock.Table 35 - Frequency Response at LSDTXFREQUENCY RESPONSE100 Hz (ref) 0 dB200 Hz -3 dB250 Hz -4 dB300 Hz < -40 dBWith 100Hz 5Vp-p square wave into 150HZ input (J1-B19), levels through the circuit areshown in the table below.Table 36 - Circuit LevelsTEST POINT VOLTAGE SIGNAL TYPETP23 1 VP-P SquareTP22 1 VP_P Rounded SquareTP21 1.25VP-P SineLSDTX 4.4VP-P(bias may vary)Sine9.4.4.7 TEST 8 - A/D CONVERTERThe A/D converter U23 is an I2C device with slave address 9E hex.

These three select lines are outputs of I2C I/O expanderU4. The three filter select lines can be seen at TP19, TP24, and TP25. Note that if input6, 7, or 8 is selected, no output will be present.If all three select lines are logic 0, then filter 0 (9600 Baud Wide Band) is selected.The mux output goes to digital pot U8, which is also an I2C device and is set to a valueof 50 (hex) for this test.
