DTC25U Operating and Service Manual lll -- TRANSCODER INSTALLATION lll -- TRANSCODER INSTALLATION To ensure long and reliable trouble-free service from the DTC25U transcoder the following steps for installation are recommended:
1. MECHANICAL INSTALLATION: The DTC25U Transcoder was designed to be installed in a building protected from the weather. The building should have a hard-surface floor such as concrete with a moisture barrier. This barrier could be pressure-treated wood sub flooring which could be anchored to the concrete and to the transmitter to make the installation earthquake resistant. Allow a minimum of three feet around the transmitter cabinet for service access. The top of the transmitter should be clear for three feet above to allow the air to exhaust from the transmitter. Provisions for air inlet and exhaust from the room must allow air flow with minimal obstruction. In the event that the room temperature exceeds 35 Celsius (95 F), cooling air must be provided so that the room temperature will not exceed 35 degrees Celsius under worse case conditions. Notice: This equipment is HEAVY and must be handled by professional movers with proper equipment. Any damage caused by the installers is not covered under warranty. Check to ensure that installing crews have proper insurance coverage. 2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for safety and operational reasons. A typical installation may be done as follows:
Use a heavy gauge wire such as 16 AWG stranded copper. The bonding between the transmitter and the ground rods must be good quality and protected from corrosion. The ground wires should run over the floor and be connected to the ground rods located outside the building. The wire should not go thru the concrete floor but over and around it. 3. AC WIRING: The DTC25U transcoder comes with a three wire 110 VAC standard plug for connection to a 110 VAC electrical outlet. It is recommended that the electrical outlet be protected with its own separate breaker and used only for the transcoder. NOTICE: All wiring of this type, except for the actual connection to the AC plug, must be done by a QUALIFIED ELECTRICIAN and must conform to LOCAL and NATIONAL wiring CODES. Consult with your electrician to ensure that the proper breaker size is selected for the main circuit. 4. ANTENNA CONNECTION: The transcoder is equipped with an N connector for output power to the transmit antenna and an F connector for connection from the receive antenna. Page 4 Section IV Transmitter Turn-On PINEAPPLE TECHNOLOGY, INC. DTC25U Operating and Service Manual lV -- TRANSCODER TURN-ON PROCEDURE lV --- TRANSCODER TURN-ON PROCEDURE (Page 1 of 3) See the previous section on installation before proceeding with this section. Improper installation of the transcoder can cause serious damage to the equipment or operating personnel and may void manufacturers warranty. Initial turn on and check out is very important for the broadcast engineer to learn how to setup and operate the transcoder. Following these steps will ensure long and reliable operation:
1. 2. 3. 4. 5. 6. 7. 8. 9. Check the transcoder output load or antenna for proper installation and connection to the transcoder. Inspect the transcoder front and back to check for broken items or lose fitting items. These must be replaced or properly secured before turning the transcoder on. Pay special attention to all RF connectors including transmit coaxial cable and antenna. Check the AC breaker and on/off switches to ensure that all are in the OFF position. Verify the switch on the power strip at the back of the cabinet and the power switch on the front of the LTX Mainframe are in the OFF position. Plug in the AC power cord to a nearby 110 AC electrical connector with associated, appropriately sized, circuit breaker. Verify the output power level on the Drake Upconverter is set to minimum ( GAIN fully CCW ). See Fig 1 below for location. On the LTX Mainframe verify XMTR switch is in STBY. Refer to the transcoder and upconverter instruction manuals in the DTC25U User Manual to locate the key functions and become familiar with the unit. Insure that all connections, including the DC power connection and the RF (IF) connection, between the 8VSB Regenerator and Upconverter have been made. Verify, using the front panel display on the transcoder upconverter, that the correct output channel has been selected. At this time, no connection should be made to the transcoder input at the back of the unit. Any following measurements will be done using the Null Packets generated inside the transcoder. Turn-on the switch located on the power strip at the rear of the DTC25U. Note: The Larcan Transcoder will come on at this time as well as the cabinet fan. A green light indication should be seen on the Drake Upconverter and, after a few minutes, the two green lights on the transcoder will turn red indicating proper operation. Locate and turn on the front panel breaker found on the LTX Mainframe and set the XMTR switch to the ON position.

The receive signal antenna can now be connected to the input of the transcoder as required. Note: The receive antenna should be located so that it will not pick up the transmitter output signal. Even when the input and output channel separation may seem to be considerable, the input receiver front end can be over loaded. This will reduce the sensitivity of the receiver resulting in degraded or loss of signal when viewed at the DTC25U transmit out. Page 7 Section V Theory of Operation PINEAPPLE TECHNOLOGY, INC. UTX1K ULTRA Operating and Service Manual V --- THEORY OF OPERATION (Page 1 of 2) A.

LOOK FOR COMAIR ROTRON P/N: 020172 Page 16 Section VIII Adjustments and Tuning PINEAPPLE TECHNOLOGY, INC. DTU25C Operating and Service Manual VIII --- ADJUSTMENTS AND TUNING VIII -- ADJUSTMENTS AND TUNING The DTU25C is a new series of digital transcoders offered by Pineapple Technology, Inc. The latest in LDMOS device and circuit technology are employed to ensure reliable and serviceable operation for many years. There are very few adjustments necessary to maintain full service condition. Typically the gain adjustment shown in the initial Transcoder Turn-On Procedure (Section IV) of this manual should require minimal attention. The front meter panel has been set up so that 100% indication in Forward Power is equivalent to 25W average output power. The input frequency (channel) can be adjusted, within the auspices of the broadcasting re-transmission rights, to the appropriate required channel (See Larcan Manual). The transmitter output must remain on the channel licensed by the FCC and in accordance with the supplied digital mask filter. Page 17 Section IX Problem Solving
Troubleshooting PINEAPPLE TECHNOLOGY, INC. DTC25U Operating and Service Manual IX -- PROBLEM SOLVING/TROUBLE SHOOTING IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 1of 2) The DTC25U is a "MODULAR ASSEMBLY" where most of the sub-assemblies can be removed and or replaced as necessary as necessary to maintain full service. To service this transmitter, it is best to become familiar with the various sub-assemblies by reviewing the transmitter block diagram and it's associated subs shown in the introduction. Any work performed on a transmitter licensed by the FCC must be performed by qualified personnel. FAILURE ANALYSIS STARTS WITH THE FOLLOWING ASSUMPTIONS:
1. The transmitter is connected to an AC source which is within the specified voltage range and has ample power to run the transmitter. 2. The antenna has been checked out and a proper match has been verified. 3. The room temperature is < +35 degrees Celsius (+95 degrees Fahrenheit) 4. There are no restrictions in the air flow in or out of the building. 5. The video and aural signals to the modulator comply with stated specifications. CHECKING THE WARNING LIGHTS There are several warning signals visible on the front of the transmitter that will alert the technician of possible problems. When viewed from the front, all the lights should be GREEN indicating normal operation. An alert signal is indicated by a RED light. We will focus on RED alert signals in this section. LTX Mainframe Assembly FAN FAULT RED indicates that the fuse supplying AC to the fan has failed. The fuse is located just inside the front panel near the top. See Fig. 1 for location. CHECK: FUSE AND/OR FAN Fig. 1 Page 18 PINEAPPLE TECHNOLOGY, INC. DTC25U Operating and Service Manual IX -- PROBLEM SOLVING/TROUBLE SHOOTING IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 2of 2) TEMP FAULT RED indicates over temperature of PA or High VSWR If High VSWR, the light will cycle 10 seconds OFF and 2 seconds ON Put transmitter in STANDBY. Investigate antenna installation and connections, check transmission lines and connections. Check that transcoder up converter is on frequency. If High Temperature, the light will cycle OFF for several minutes then ON for several minutes. Check: Room temperature Check: For Blocked Air Filter Check: For Blocked Air Flow Check: Transcoder Drive level. Verify output power is at 100% or less. NOTE: If the AC Power is ON and all LED's are OFF and all meter readings are Zero (0) the DC Power Supply may cycle on and off if the internal fan has failed or Hi temp has failed. The internal DC supply may have failed and needs replacing. Transcoder Assembly The Transcoder Assembly consists of the Larcan receiver and the Drake up converter. For adjustment of the transcoder and understanding fault indications, refer to the Larcan and Drake manuals. Page 19 Section X Warranty PINEAPPLE TECHNOLOGY, INC.
