Carefully read all material in this section prior to installation. Also read and review operating procedures later in this section. Building Recommendations The quality of the building is of great importance if you are to expect long life and continued performance from the processor. The building must be clean, dry, temperature controlled and secure. The processor takes up a single 1-U high space on a 19” rack. Don’t forget to allow space in the building for any additional racks to house test equipment, a workbench area, line regulating transformers, ladders, equipment and parts storage, first aid kit, emergency generator if used, as well as heating and cooling devices that may be unique to your installation. A sloping roof will tend to develop leaks less rapidly. The building should be well roofed with good material. The cooling load will be lowered with reflective or light colored roofing material. Heating and Cooling Requirements The environment’s temperature will contribute greatly to the length of the processor’s life. Technalogix recommends that the building’s filtered air intake must have capacity for all air-flow in the building plus an additional 20%. Keep the intake below the roofline to avoid intake of solar heated air. Please ensure that the intake and exhaust areas are on the same side of the building to avoid pressure differentials during windy conditions. Also, do not position intake near exhaust’s preheated air. If air conditioning is required to cool the shelter, discuss the situation with a qualified HVAC technician. Under average conditions, 12,000 BTUs will cool approximately 500 square feet to a comfortable level. 10 P-379 Processor Electrical Service Recommendations Technalogix recommends that a qualified, licensed local electrician be consulted for the required electrical service. We suggest local electricians because: • The personnel knows the local codes • The personnel can be on site readily • You are apt to get better overall support if you give what business you can to local suppliers Technalogix recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the power amplifier. All electrical service should be installed with your national electrical code in your area, any applicable provincial or state codes, and good engineering practice. Special consideration should be given to lightning protection of all systems in view of the vulnerability of most translator sites to lightening. Lightning arrestors are recommended in the service entrance. Straight and short grounds are recommended. The electrical serviced must be well grounded. Do not connect the unit to an open delta primary power supply, as voltage fluctuations could harm the unit. Branch your circuits. Do not allow your lights, your workbench plugs, and your translating equipment off of one circuit breaker. Each translator should have its own circuit breaker, so a failure in one does not shut off the whole installation. 11 P-379 Processor Antenna and Tower Recommendations Your preliminary engineering workgroup should establish your antenna and tower requirements, both for receiving and transmitting antennas. Construction of sturdy, high quality antenna/tower systems will pay off in terms of coverage of your service area, the overall quality and saleability of your radiated signal, and reduced maintenance expenses. Technalogix provides complete turnkey antenna systems if needed. If your site is serving as a translator, your receiving antenna should be line of sight to the originating station, both winter and summer. The foliage will change with season. Transmitting antennas can enhance or seriously impair the translator output. It is assumed that one has been selected prior to system installation, but the best-designed antenna system will function poorly if shortcuts and compromises are used during installation. Follow the manufacturer’s instructions exactly, along with any engineering data prepared for the site. The selection, routing, and length of coaxial cable are extremely important in the installation. If there is a 3 dB line loss in the cable between your unit’s output and the transmitting antenna, a 500 watt unit will only deliver 250 watts to the antenna. Buy the best cable you can obtain, route it via the shortest way to the antenna, and keep it straight. Do not form it into sharp bends on its way. Do not use any more cable fittings for the installation than absolutely necessary. All cautions here apply equally to all coaxial cables in the system - input and output. The better known tower manufacturers offer complete technical and safety documentation with their towers. Be sure that you have this information as it regards wind loading, guying, etc. Be absolutely safe and certain about this aspect as human lives may be at stake. Shelter Security The FCC requires that the translator be secure from entry or control by unauthorized persons, and that any hazardous voltages or other dangers (including most tower bases) be protected by locks or fences as necessary to protect personnel and prevent unauthorized tampering or operation. Security of the building further implies that it be secure from wildlife. Use sturdy construction materials, including sheet metal if necessary. Holes around conduit, cable, and other similar entry points should be stuffed with steel wool and caulked to prevent entry of wildlife. Other features of security for your shelter may include its location with respect to the prevailing wind conditions. Location leeward of some natural topographical feature will prevent wind damage and snowdrifts. Check the soil runoff conditions that may slow or hasten wind or water erosion and other concerns that may be unique to your location. 12 P-379 Processor Unpacking and Inspection Check the outside of the container. Carefully open the container and remove the processor. Retain all packing material that can be reassembled in the event that the equipment must be returned to the factory. Exercise care in handling equipment during inspection to prevent damage due to rough or careless handling. Visually inspect the enclosure of the processor for damage that may have occurred during shipment. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in connectors. Inspect all connectors for bent connector pins. If the equipment is damaged, a claim should be filed with the carrier once the extent of the damage is assessed. Technalogix cannot stress too strongly the importance of immediate careful inspection of the equipment and subsequent immediate filing of the necessary claims against the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person. If the equipment is damaged, the carrier is your first area of recourse. If the equipment is damaged and must be returned to the factory, phone for a return authorization. Claims for loss or damage may not be withheld from any payment to Technalogix, nor may any payment due be withheld pending the outcome thereof. Technalogix cannot guarantee the carrier’s performance. 13 P-379 Processor Location and Function of Controls and Connectors The following illustrations depict the location of the installation connectors when installing the power amplifier with a processor. FRONT BACK Aural Carrier Level - Allows user to set aural carrier level relative to visual carrier level. Processor is factory tested at –10 dBc (decibels below visual carrier). Input Source – Allows the user to select between cable HRC, cable standard or off-air. Input Select – Allows the user to select the desire channel for input signal. Output Select – Selects the desired channel of operation. If you require a lower channel than the one currently displayed, push the toggle switch down. The channels will change one at a time as many times as you press the switch. Holding the select switch in the up or down position will “scan” to the desired channel. It is normal for the frequency lock LED to turn off during and for a few seconds after, changing channels. The switch must be held up or down initially for three seconds. This helps to ensure that no accidental channel changes will occur. Output Level – Sets visual carrier output level. RF Out Test Point – Provides a sample of the RF output level which is 20 dB below the actual value. RF test point is only a relative indicator of the actual RF output level and may vary. All RF operating measurements should be made at the RF output of the unit. RF Output - Modulated Audio/ Video output capable of +60 dBmV levels using built in low distortion hybrid amplifiers. 14 P-379 Processor RS-232 Ports – Set up for optional RS-232 control option. Combined IF Input/ Output – 45.75 MHz visual carrier and 41.25 MHz audio carrier intermediate frequency signal loop. RF In – Modulated RF input – Recommended RF input is 0 dBmV to 5 dBmV. T-Channel Switch – Allows the user to switch the optional T-channel on or off. To use the T-Channel Input Option, if the unit is so equipped, ensure that that a T-channel input source is attached to the F-connector marked “T-Channel IN” on the rear panel. Position the T-Channel switch on the rear panel of the P-379 to the “ON” position. 15 P-379 Processor 5.0 OPERATING PROCEDURE Preliminary Hook-up 1. Position the Technalogix P-379 agile processor in its installation mount or rack. 2. Locate the antenna lead or cable drop that will provide the input signal for the P379 agile processor. 3. Ensure that the input signal provides an adequate signal. The recommended input level for best performance from the Technalogix P-379 Processor is 0 to +10dBmV (+60dBuV to +70dBuV). Setup and Operation 1. Connect the input-source cable drop or antenna lead to the F connector On the rear panel of the P-379 marked “RF INPUT”. NOTE: If you have a P-379T, also connect the T- or return-channel input source cable to the F-connector on the rear panel of the P-379 marked “T-INPUT”. 2. Connect the output of the P-379 to a 50 Ohms load via an RF cable connected to the F-connector marked “RF OUTPUT” on the rear panel of the P-379. 3. Connect the Technalogix P-379 to a proper AC electrical source. The correct electrical input type for the unit is marked on the rear panel, directly under the entrance of the power cord into the unit. Exercise care in handling equipment during inspection to prevent Damage due to rough or careless handling. Technalogix power supplies are designed so that, under certain power line or heat buildup conditions, the unit shuts off. An indication is no RF output, although the POWER LED on the front panel remains illuminated. If this occurs, unplug the power cord and wait at least two (2) minutes before reapplying power. Upon reapplying power, you should again have RF output. If the unit fails to provide RF output again, or should the unit return to shutdown mode, telephone your distributor for assistance or call Technalogix direct at 403-347-5400. Remember: Technalogix recommends a 1.75” air circulation space between each piece of rackmounted equipment. 16 P-379 Processor 4. Input channel selection. Select the desired input source type and channel using the front panel controls. Because the built-in input offset feature automatically removes any input offset, no calculations or adjustments are required. The Technalogix P-379 Agile Processor has a built-in delay in the input- and outputchannel tuning circuits. In order to change channels, hold the channel select switch in the up- or down-position for at least three seconds. When the circuit is defeated, channel selection will proceed normally. Channels can be changed one at a time by raising/lowering the channel select switch one channel at a time; or channels can be scanned rapidly by raising/lowering the channel select switch and holding it while the unit rapidly moves through the channels. However, once the channel select switch is released for more than one second, the delay-tuning circuit reactivates. Until an active input channel is selected, the input channel display will flash. Once the input channel is selected, the input channel display will stop flashing as long as the input signal level is within the required capture range. If the input channel display continues to flash after a known, active input channel is selected, check the level of the input signal to ensure it is at adequate levels for detection (from –5dBmV to +10dBmV) and not too low or too high. The FREQUENCY LOCK LED on the front panel display may also blink during input-channel tuning. This is because, when the unit is being tuned, an RFoutput muting circuit is enabled to ensure that moving RF carriers do not interfere with any existing channels on the cable system. T-Channel Input Option. To use the T-Channel Input Option, if the unit is so equipped, ensure that that a T-channel input source is attached to the Fconnector marked “T-Channel IN” on the rear panel. Position the T-Channel switch on the rear panel of the P-379 to the “ON” position. If your P-379 has green LED’s on the front panel, above the channel select switch, the LED marked “T-channel” will illuminate when a channel in that range is selected. If your P-379 does not have green LED’s, but does have a threenumber channel display, the selected T-channel will be indicated by a “-“ (minus) sign preceding the number of the T-channel selected. When in T-channel operation, only the T-channels will be selected. 17 P-379 Processor 5. Select the desired output channel. Unless otherwise specified, the unit is factory set for cable standard channel frequencies and the microprocessor automatically selects the proper FCC offset for the output channels, requiring no calculations or adjustments. NOTE: For HRC output channels, see the section in this manual entitled HRC Output Frequency Set. During output-channel tuning, the FREQUENCY LOCK LED on the front panel display may also blink during input-channel tuning. This is because, when the unit is being tuned, an RF-output muting circuit is enabled to ensure that moving RF carriers do not interfere with any existing channels on the cable system. 6. Connect a spectrum analyzer (recommended) or a field strength meter to the Fconnector marked “RF OUTPUT” on the rear panel of the P-379 agile processor. If the unit is already connected to another device, disconnect that device from the unit. 7. using the front panel control marked “OUTPUT LEVEL,” adjust the RF output of the unit. The recommended output level is between +55dBmV and +60dBmV (+115dBuV and +120dBuV). Setting the RF output level below +55dBmV may adversely affect the parameters of the modulating signal; setting the RF output level above +60dBmV will adversely affect the quality of performance of the P-379. Ensure that the RF output level is checked each time an output channel is selected, particularly when the selected channel is a return or “T” channel or when the channel selected is in a different band from the previous channel. NOTE: Ensure that you do not overdrive the power amplifier. Please see the power amplifier manual for recommended levels. 18 P-379 Processor 8. While the RF OUTPUT signal is still connected to the spectrum analyzer or field strength meter, observe the aural carrier level. The difference between the video carrier level and the audio carrier level – the “Delta AV” or ΔAV – should be the same as the input source. In other words, if the RF INPUT signal ΔAV is 13dB, the RF OUTPUT signal ΔAV should be 13dB ±2dB. Minor adjustment of this ΔAV may be made either at the input signal source (if the input signal is not from an off-air source) or with the AURAL CARRIER LEVEL control on the front panel of the P-379. When switching to either of the frequency sources (STD or HRC), the internal aural carrier attenuator drops automatically from 6dB to 0dB since the ΔAV for cable signals has normally been preset at the headend. However, the ΔAV for off-air signals may vary considerably. Normal operation level of the aural carrier is 10 to 13dB below the video carrier. If adjustment of the AURAL CARRIER LEVEL control on the front panel of the P-379 will not bring the ΔAV of an off-air signal into an acceptable range, check the ΔAV of the input signal. If the ΔAV of the input signal is too small or is negative (the aural carrier is above the video carrier), it is possible that the AURAL CARRIER LEVEL control of the P-379 will be unable to compensate. Check the input signal before contacting Technalogix for return-for-repair information. 19 P-379 Processor Translator Hookup 1. Connect modulated video from P-379 RF OUT to the Technalogix power amplifier. 2. Turn down RF level on P-379 all the way. 3. Ensure that IF OUT is connected to IF IN on the P-379 processor using the loop F to F cable supplied. 4. Connect the transmitting antenna cable to the RF output connector on the power amplifier. It is recommended that a quality through line wattmeter be installed in this same line. 5. Verify that all signal and RF cables are connected properly. 6. After following proper installation procedures outlined in the power amplifier manual, plug the power amplifier’s power cords into an appropriate electrical outlet. Output power should be adjusted with a sync and blanking signal only with the aural carrier removed. This is simply done by disconnecting one end of the audio carrier loop found on the back panel of the P-379. AUTOMATIC MORSE CODE KEYING DEVICE Translators must be equipped with a device that identifies the call signal of the translator in Morse code (usually be frequency shifting the aural carrier not less than 5 kHz or amplitude modulating the aural carrier with a 200 Hertz tone) once each hour. This feature can be disabled if the parent station for the translator sends the call sign of the translator in the visual picture or identifies it as part of the aural modulation. The end user must do this as a regulation of FCC. 20 P-379 Processor 6.0 PROBLEM TROUBLESHOOTING GUIDE The guide below covers some typical symptoms, possible associated causes and suggested actions to follow before returning the unit for repair. It is not meant to be allinclusive. Symptom Possible Cause Suggested Action No output Weak output Unit tuned to output channel different from desired (this occurs particularly on the units which have green LED on the front panel to indicate “T” channels and channels above 99) Unit tuned to input channel in a different range than desired Ensure selected output channel is desired channel Input signal is too weak Excessive noise Spurious signals IF loop cable on rear of unit loose/disconnected Unit not plugged in or not getting power Output level above rated maximum (most often occurs when changing from highnumber channel to lownumber channel, especially to the “T” channels) IF level too high (most often occurs when routing IF through scrambler or other external device) Input signal too strong or no input signal at all Bad/noisy video Aural carrier interfering with video carrier Channels do not change Delay feature active 21 Check INPUT SOURCE SELECT switch for proper source selection Ensure input signal strength is within specified range Check IF loop cable is securely attached Check power cord and power source, fuse Measure RF output from rear panel jack and adjust front panel OUTPUT LEVEL control as required Measure normal IF output level for applied CW /unmodulated input carrier and ensure same level is returned to unit after external processing Measure input RF level and pad to within specified input levels; if signal not present, change to active channel Measure Aural Carrier level and/or adjust AURAL CARRIER LEVEL control on front panel Hold channel change switch in raised/lowered position for at least three seconds P-379 Processor 7.0 BILL OF MATERIALS, SCHEMATICS, AND PCB OVERLAYS Agile Logic Board Bill of Materials Last Revision: 09.12.00 Component Reference Quantity Identification C1 C10 C11 C12 C13 C14 C15 C16 C17 C18 C19 C2 C20 C21 C22 C23 C24 C3 C4 C5 C6 C7 C8 C9 D1 D2 D3 DS1 JP1 JP2 JP3 JP4 JP5 JP6 JP7 JP8 L1 22pF 0.47uF 10 uF 22 uF 22 uF 22 uF 22 uF 0.01uF 0.01uF 47 uF 47 uF 22pF Modifier 0.01uF 0.01uF 0.01uF 0.01uF 22 uF 10 uF 0.47uF 0.47uF 0.01uF 0.01uF 470 uF RED T1 T1 W/HLD RED T1 8 POS 4 POS HEADER 8 POS HEADER 3PIN 3PIN 3PIN 3 POS 3 IL 6T 22 Package CAP250D CAP100RP CAP100RP CAP100RP CAP100RP CAP100RP CAP100RP CAP250D CAP250D CAP100RP CAP100RP CAP250D CAP100RP CAP250D CAP250D CAP250D CAP250D CAP100RP CAP100RP CAP100RP CAP100RP CAP250D CAP250D CAP197R LED T1-W/HLD LED LED T1-W/HLD DPS8W JP-DUAL4 JP-DUAL8 JP-DUAL4 JP3IL JP3IL JP3IL JP3IL JP3IL COIL 60 P-379 Processor L2 L3 L4 L5 P1 P10 P11 P12 P2 P3 P4 P5 P6 P7 P8 P9 Q1 Q2 QP1 R1 R10 R11 R12 R13 R14 R15 R16 R17 R18 R19 R2 R20 R21 R22 R23 R3 R4 R5 R6 R7 R8 R9 RP1 RP2 6T 6T 6T 6T 4 PIN 10 POS 4 PIN 8 POS RT ANG F 12 POS 12 POS ON DISPLAY BDS 12 POS 12 POS 4 PIN 10 PIN 2222 2907 4-2222A 10 MΩhm 1 kΩhm 5 kΩhm 10 KΩhm 10 KΩhm 1 kΩhm 6.8 kΩhm 1 kΩhm 500 Ωhm 10 KΩhm 5.6 kΩhm 4.7 Ωhm 10 KΩhm 91 Ωhm 10 Ωhm 5 kΩhm 5 kΩhm 10 kΩhm 1 kΩhm 68 kΩhm 68 kΩhm 68 kΩhm 4.7 Ωhm 10 kΩhm 10 kΩhm 23 COIL 60 COIL 60 COIL 60 COIL 60 SMB DIPIL10 SMB CONNIL8 FCONN CONN IL12 CONN IL12 CONN IL19 CONN IL12 CONN IL12 SMB CONN10IL TRANS2222 TO18C DIP14C RES1-8 RES1-8 POT1 RES1-8 RES1-8 RES1-8 RES1-8 RES1-8 POT1 RES1-8 RES1-8 RES1-8 RES1-8 RES1-8 RES1-8 POT1 POT1 RES1-8 RES1-8 RES1-8 RES1-8 RES1-8 RES1-8 DIPIL11 DIPIL11 P-379 Processor RP3 RP4 RP5 SW1 SW2 SW3 SW4 U1 U2 U3 U4 U5 U6 U7 U8 Y1 10 kΩhm 150 Ωhm 150 Ωhm PADDLE PADDLE ROCKER ROCKER MC74HC165 IC34064 68705C8 74H04 74H04 MC14499 DS232 X2402 4MHz 24 DIPIL11 DIP IL8 DIP IL8 SW1 SW1 SW1 SW1 DIP16C REGTO92 DIP40C DIP14C DIP14C DIP18C DIP16C DIP8C XTAL P-379 Processor 1 10 5V 5V R11 +12V IN RP3 U7 16 15 14 13 12 11 10 R18 MUTE Q1 D4 R16 360 VIDEO MODULATION C3 C12 37 36 34 22 21 C14 10 U11 P8 P7 P6 P5 RSTX RSRX RDI TDO R8 LD LDI C1 C10 R7 R6 LDO C6 C5 C9 EEPROM MEMORY STORAGE 32 U8 P1 P2 P3 P4 RP5 5V P8 P7 P6 P5 C2 U9 18 17 16 15 14 13 12 11 10 RP4 JP2 10 11 12 13 14 15 16 17 18 19 20 16 15 14 13 12 11 10 U1A PLLI EN PLLO EN9 PLL EN 4 +5V 12 L4 C22 C21 SPR51 10 POWER ON LED 14 25 KHz 12.5KHz TO RP RJ11 +12V FROM P/S P12 U2D U2C U2B P3 1 REF 2 DATA 3 LDO 4 12.5KHz 5OUT PLL EN 6 CLOCK 7 25KHz +12V +5V +24V -12V +12V TO OUTPUT CONV.
