Safety Information Before you use your radio, ensure that you have read and understood this publication, as well as safety requirements. CAUTION – A license is required before operating radio communication equipment. Warnings and cautions An absence of specific alerts does not mean that there are no safety risks involved. Always follow the instructions that accompany a Warning or Caution. The information they provide is intended to minimize the risk of personal injury and/or damage to the equipment.
– 15 cm (approximately 6 in) for the TDL 450i radio @ 1 W • Do not operate the transceiver unless all RF connectors are secure and any open connectors are properly terminated. • Avoid contact with the antenna while operating the transceiver. • Do not operate the transceiver with a damaged antenna. If a damaged antenna comes in contact with the skin, a minor burn may result. • Do not operate the equipment near electrical blasting caps or in an explosive atmosphere.
installations, you should not use frequencies set aside for itinerant operations, but should coordinate a frequency based on the fixed area operation. Regulations differ from country to country, please be aware of the local regulations before using radio equipment. Automatic station identification For operation in the United States, the FCC requires that radio transmitters broadcast a station identifier every 15 minutes. The station identifier is the call sign assigned to you on the station license.

Introduction This guide provides information concerning the integration of the TDL 450i radio modem transceiver into your product (Model Numbers XDLM-0, XDLM-1 and XDLM-2). This guide should be used in conjunction with the XDLCONF User’s Guide – Dealer Version that should be referenced for general information concerning the configuration of TDL 450i modems, and also for detailed programming information.
TDL 450i in Test Board Interface Port Pin Out The standard TDL 450i transceiver comprises a 30-pin port for power, data and interfacing with other electronic devices. 30 Pin TDL 450i Board The following signals are available on the 30-pin connector: Pin 1 2 3 4 5 6 Name GND DO NOT USE TX DO NOT USE GND DO NOT USE TDL 450i Intergrator’s Guide Description GROUND FOR SIGNAL AND POWER FACTORY USE ONLY, NO CONNECTION TX DATA, DTE SERIAL PORT, 3V CMOS (3.

Antenna Port A coaxial antenna port is provided for connecting the antenna system to the TDL 450i transceiver. The antenna connector is a 50-Ohm MMCX type. Appendix B provides part numbers and manufacturer information for compatible interface and RF connectors. Pacific Crest also provides custom manufactured cables designed to your specific needs. Contact us for a quotation for your specific cabling requirements. Warning: Don’t transmit without first connecting an antenna.

You should turn CSMA off in EU countries. TDL 450i Factory Default Settings Up to 32 frequencies are stored in the configuration memory called the channel table.
Electrical Considerations Power Supply The TDL 450i transceiver has a power supply connection on Pin 18 and Pins 23 to 28 of the interface connector. Pins 1, 5,7, 9,30 and Pins 19 to 22 are connections to both power ground and serial interface signal grounds. Note that these pins are tied to a common point on the TDL 450i transceiver.
Error Codes The TDL 450i transceiver performs a variety of power-up and run-time tests to assure optimal operation. Tests include environmental as well as electrical measurements designed to avoid damage to the unit while maintaining adequate operation. A 50Ω impedance coaxial MMCX style RF connector is provided for attachment to an external antenna system. The MMCX connector offers a positive friction locking mechanism that is very reliable.
