DESCRIPTION
RST
NMI
Resets the SLRM900. By resetting the
SLRM900, all programmable parameters
will be preset to their default values
described in data sheet: "SLRM900 I-CODE
Long Range Reader Module, protocol
Reader-Host", except for stored RF output
power and modulation index. The SLRM900
will restart with the mode selected by jumper
JP3 (see Table 3).
Non Maskable Interrupt. To change from the
default start-up mode to the alternative
mode (see setting of jumper JP3 in Table 3).
For switching back to default start-up mode,
press switch RST (SW1).

Notes
1. Typical ratings are not guaranteed. These values listed are at Tamb = 25 °C.
2. Values listed above are continuous currents; peak values can be up to 650 mA higher, by switching, or modulating
the RF carrier.
3. Calculated from the measured RF output voltage across a 50 Ω load; RF output voltage measured with Tektronix
TDS520B oscilloscope.
4. Default value, adjusted at delivery.
5. Definition: m = V-V----mm----aa--xx----+–----V-V----mm----ii-nn- where Vmax is RF level without modulation and Vmin is RF level during modulation.
Modulation method is Amplitude Shift Keying (ASK).
