1 INTRODUCTION:
SD Series Introduction
The SD Series model beacon transmitters are computer controlled systems designed around the Motorola
ColdFire
®
microprocessor. These systems are capable of remote monitoring and maintenance via several
communication methods including RS232, RS 422, and RS485 protocols. An optional operator front panel offers the
common user controls normally found on an analog transmitter. These panels may also be used for remote control.
With the exception of main power application, all aspects of transmitter setup and operation come under the direct
control of the Controller / Monitor. The following are all programmable:
* Direct Digital Synthesis (DDS) of RF frequency and Audio Tone Frequency
* Identifier Morse code dot, dash and space intervals.
* Customer IDENT sequence
* Standard Alarms
* Additional Fault handling based on multipoint voltage, current and temperature monitoring
* Transfer Criteria (Dual Only)
* Power limits
* Modulation limits

The Controller / Monitor itself can be controlled and monitored by another computer system connected locally via
one of the hard wire protocols mentioned above or remotely using phone lines or any other carrier which can handle a
standard US Robotics modem spectral output.
