Type-II Transponder Block Diagram 5.0 Modes of Operation: “The type-II tags can only operate in one of the four following modes, sleep, makeup, active, and time-out.
Page Time-Out Mode 06/09/97 3:43 PM Type-Ii, Type-II+, Type-II Technical Manual After the Transponder has successfully processed all of the data slot and activation commands, the TOLE transitions to a Time-Out Mode. During this mode the 32-Khz timer disables the 4 MHz oscillator, all data detection circuits, and any other unnecessary circuits. The length of the time-out is controlled by the reader (and is included in the RCM) and ranges from 0 to 30 seconds.
TOLE Type-1, Type-II+, Type-II Technical Manual 06/09/97 3:43 PM Page Detailed Operation: What follows is a detailed description of actual circuit operation down to the component level. The reference designation are those found on the appropriate schematic listed at the beginning of this document. And while this document references those designation, the schematic remains as the controlling document should an unforeseen discrepancy exist. 6.1 RF Board 6.1.
Page 10 of 39 06/09/97 3:43 PM Type-II, Type-I+, Typewrite Technical Manual ‘When in the receive mode the TUSCON signal (TOLE IC pin 27) is low leaving QS in its off state. Therefore the two diodes are without any forward bias and are thus off. Since they have very low junction capacitance very little 915 MHz energy leaks through them. Therefore the incident received RF energy is applied to the 50-ohm filterer Ul. When transmitting TUSCON is high which turns on QS.
TOLE Type-11, Typewrite, Type-III Technical Manual 06/09/97 3:43 PM Page 11 of 39 6.1.1.6 Detector Diode Bias Network The detector diode bias network consisting of R12 and R13 is used to forward bias the diode during receive mode. The steady-state voltage at TP9 is about 0.2V, the forward voltage of a Scottish diode. Notice that the cathode of the detector is sitting at DC ground. 6.1.1.

The input pin on the IC is pin 8 and the crystal drive pins pin 7, This circuit performs all the basic timing functions of the IC and tag. It times the sleep mode, the makeup interval, the LED flash rate and duty cycle, the beeper sounding rate and duty cycle and the sleep time-out period.
TOLE Type-I, Type-II+, Type-III Technical Manual 06/09/97 3:43 PM Page 13 of 39 The crystal startup time is specified in the TOLE spec as a maximum of § sec. 6.1.2.4 Current Reference The current reference pin is pin 12, Resistor R11 and decouple C51 are used to provide the proper bias current reference for the 32 Khz oscillator and input amplifier. A typical voltage to be expected at this pin is: Sleep mode: 55mV DC. Active mode: 55mv DC. 6.1.2.
Page 14 of 39 06/09/97 3:43 PM Type-II, Type-l+, Type-IT Technical Manual 6.1.2.9 TOLE IC Power Pins Pins BATAAN (pin 13), BATMEN (pin 15), and BATED (pin 25) supply the power to the various circuit blocks internal to the IC. Type-IL tags have these pins all tied to the battery. Capacitors C19, €22,C24, C26 provide a wide range of decoupling/filtering for these power pins. 6.1.2.
TOLE Type-II, Type-11+, Type-Eli Technical Manual 06/09/97 3:43 PM Page 15 of 39 The oscillator is comprised of transistors Q3 and Q4 (Siemens BF P-183), U2 (REM SAW, RP1094), and a few sundry bias/bypass components described below. U2 is a 2-port quartz Surface Acoustic Wave (SAW) integrated circuit resonator designed for resonance at 915 MHz. Q3 and Q4 provide enough gain to overcome the insertion loss of the resonator with enough left over to drive the downstream attenuation load.

When DATABASE is high, transistor Q1 is cutoff thus Quest's collector is O volts. Therefore no RF signal is presented to the antenna. Likewise when DATABASE is low, Ql is biased into conduction via base divider R2 and R3, QI conducts providing +3V power to the collector of Ql.
TOLE Type-IL, Type-1+, Type-II Technical Manual 06/09/97 3:43 PM Page 17 of 39 The beeper can be in an off , confirmation, or warning mode. The off mode is self-explanatory. The beeper confirmation tone is an intermittent pulsed 4096-Hz tone with a total duration sec. This tone consists of four chirp tones. Each chirp tone shall have a period of 0.5 seconds and a duty cycle of 50%. The warning or “negative confirmation” tone is a continuous 4096-Hz tone with a total duration seconds, 7.
Page 18 of 39 06/09/97 3:43 PM Type-IL, Type-II+, Type-HI Technical Manual 7.1 Common Symptoms: Tag does not wake up: This symptom is confirmed by the amount of current the tag draws, When in the sleep mode it draws about 15 uA. When in the acquisition mode it draws perhaps 100 to 150 uA and when fully awake and talking to the reader it draws about the average. The tag does not transmit any signal in the sleep or acquisition modes.
