Section IIITransmitterInstallation
PINEAPPLE TECHNOLOGY, INC. DTC25U Operating and Service Manual lll -- TRANSCODER INSTALLATIONlll -- TRANSCODER INSTALLATIONTo ensure long and reliable trouble-free service from the DTC25U transcoder the following stepsfor installation are recommended:1. MECHANICAL INSTALLATION: The DTC25U Transcoder was designed to be installed in a buildingprotected 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 anchoredto 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 thetransmitter 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 35º Celsius (95º F), cooling air must be providedso that the room temperature will not exceed 35 degrees Celsius under worse case conditions.Notice: This equipment is HEAVYand must be handled by professional movers with properequipment. Any damage caused by the installers is not covered under warranty. Check to ensurethat installing crews have proper insurance coverage.2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly forsafety 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 IVTransmitterTurn-On
PINEAPPLE TECHNOLOGY, INC. DTC25U Operating and Service Manual lV -- TRANSCODER TURN-ON PROCEDURElV --- TRANSCODER TURN-ON PROCEDURE (Page 1 of 3)See the previous section on installation before proceeding with this section. Improper installation of thetranscoder can cause serious damage to the equipment or operating personnel and may voidmanufacturers warranty. Initial turn on and check out is very important for the broadcast engineer tolearn how to setup and operate the transcoder. Following these steps will ensure long and reliable operation:1. Check the transcoder output load or antenna for proper installation and connection to the transcoder.2. Inspect the transcoder front and back to check for broken items or lose fitting items. These mustbe replaced or properly secured before turning the transcoder on. Pay special attention to all RFconnectors including transmit coaxial cable and antenna. 3. Check the AC breaker and on/off switches to ensure that all are in the OFF position.4. 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 electricalconnector with associated, appropriately sized, circuit breaker.5. 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.6. 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. 7. 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.8. 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.9. 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 outputsignal. 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 thereceiver resulting in degraded or loss of signal when viewed at the DTC25U transmit out. Page 7
