Table 9. Auto-Poll Example Bit Sequence
Figure 17. D19 = D18 = 1, D17 = D0 = 0
Auto-Poll Programming Example
Auto-Poll example (see Figure 18):
D0 = D1 = D2 = 0, no dese nse
D3 = D4 = 0, demodulator bandwidth = 17 12 h ertz, 1
kHz baud rate, pulse = 500μsec.
Required demodulator bandwidth is 0.65/ 500usec =
1300 hertz
D5 = D6 = 1, Slice level = 50%
D7 = 0, D8 = 1, bit check = 4 bits.
This is the time th e devic e is ON checking for four
consecutive valid w indows.
D9 = D10 = 1, D1 1 = 0, data rate is 1 kHz, (500μsec
pulses), window set to 433μsec (< 500 usec)
D12 = D13 = 0, D14 = 1, sleep timer set to 160msec,
that is, 4 bit is ON and 160msec is OFF.
D15 = 1, device is placed in autopoll
D16 = 0, not used. Always set to 0.
D17 = 0, squelch is OFF
D18 = 1, watchdog timer is OFF
D19 = 0, no RSSI offset
