S & A Systems Fleetwatch Series TRM303 Transceiver Version 1.0.0 Operational Overview December 4, 2001 Operational Overview The TRM303 is controlled by a Microchip PIC16F876-04I/P RISC microcontroller. When instructed by serial command, the unit emits a beacon signal designed to trigger a Fleetwatch Electronic Trip Recorder. This beacon signal is a 4.25 second burst consisting of a 770 Hz stream of pulses with a 25% duty cycle over the 303.875 MHz transmitter (Refer to diagram “Data Transmit Modulation Scheme”). At the end of the beacon signal, the T/R Switch connects the receiver to the antenna and the unit looks for data on the same 303.875 MHz band. A small delay (approximately 1 second) occurs between the end of the beacon signal and the beginning of the data chain coming back to the TRM. This delay is required for backwards compatibility with previous readers, which required time for the Automatic Gain Control (AGC) circuitry to readjust to read the low-power signals returned by the RF devices, as well as for the transmitter circuitry in the device being read to power up. This delay is not required by the TRM. The microcontroller waits and examines the received data line from the receiver. A serial message is sent (over the RS-232 channel) indicating whether data was received or not, and passes either the data or a code indicating why the data could not be decoded. System Overview The TRM303 circuitry consists of three principal sections: 1) Processing Circuitry 2) Power Control & Distribution 3) Transmitter/Receiver The block diagram entitled "TRM303 Block Diagram" shows how each group interacts with each other. The Processing circuitry is the heart of the system. It controls all facets of the unit and is responsible for communication, RF control, and power operations. The Power Control system provides regulated power to the system and to monitor for out of tolerance voltages. This enables the system to turn itself off in order to prevent either damage or errant operation. It is also provided with sufficient intelligence to enable the unit to shut itself down to conserve power. Note that the unit is actually responsible for turning itself on and off. There is no mechanical on/off switch. In an error condition, the unit will default off. The receiver system is responsible for accepting and multiplexing signals from the RF link. It is designed to work at 303.825 MHz in the USA, but can be easily modified to other frequencies of interest. The Transmitter circuitry is responsible for reliably sending data over the RF link. It is also designed to work at 303.825 MHz in the USA, but can easily be modified to operate at other frequencies. The circuitry is equipped to modify it’s power level on the fly, allowing it to operate under the rules/regulations specified by different countries. Processing Circuitry The processing circuitry is the “brain” of the device. It is responsible for all aspects of control and communication. The heart of the design is the microcontroller U4, a Microchip PIC16LF876. This unit is equipped with 8K of onboard flash memory, 368 bytes of SRAM, 256 bytes of EEPROM, and a UART (as well as many other peripherals). The controller receives power from a single VDD line. The line is filtered for low frequency transients by C30. Manual reset of the controller is provided by switch SW1, which grounds the /RESET line through R20/D14 combination when pressed. Reset control is also available to an external controller through the use of the RESET line on the external connector. Any voltage between approximately 0- .5V will reset and hold in reset the TRM (active low). D1 prevents any positive voltages from entering the unit. D14 is present to prevent the voltage present from the In Circuit Programming (ICP) unit from shorting it’s +5Vdc supply to the TRM303 unit’s +3.3Vdc supply and damaging either device. The processor is timed off of crystal X1 running at 3.6864 MHz. C31 and C32 provide the parallel resonant circuit for the crystal oscillator. This frequency supplies only the microcontroller and does not traverse any distance on the PC board. Command input to the microcontroller is through COM1, which is an RS-232e port. The COM port is level shifted by U3, a standard RS232 level shifter. The inputs of this device (Sipex Part #SP3222ET or equivalent) are protected from ESD to +- 15kv. C11, C12, C13, C17, and C20 provide voltage doubler circuits for the level shifting. The comm port can be powered down (except for one receiver port) to conserve battery power. Status LEDs (D9 and D11) light during communications on the Tx and Rx lines, respectively. Theses lights are on a timing circuit which causes them to stay lit past the active time (approximately ½ second). These timing circuits are made from the not gates of U5(gates A,D, E, and F), diodes D3 and D8, capacitors C18 and C25, and resistors R12 and R15. The timing circuits work identically for both Tx and Rx. The Tx signal enters gate F of U5 and is inverted. This produces a normally low signal. When the Tx signal goes active (low), a high is produced. This voltage flows through D3 and charges (very rapidly) C18. This voltage is then re- inverted by U5A, producing a low which allows current to flow through the current limiting resistor R16, through the status LED D9 (thus lighting it), grounded into the output of U5A. When the Tx signal goes back high, the voltage on C18 slowly discharges through the parallel resistor R12 (according to the RC time constant). D3 prevents the voltage on C18 from being shunted back through the output of U5F. When the C18 voltage discharges to a sufficiently low voltage, the LED (D9) is turned back off. In this way, even fast communication signals will trigger a viewable pulse on the LED. Connection to the outside world is made by a shielded RJ45 jack (CONN1). This connection provides for Tx, Rx, and the standard RTS/CTS lines. A test connector (CONN3) provides for quick input/tap capabilities…
