SmartPoint Module for the Elster A3 Meter ECMTM40000
5.2.4 Base Frequency Channel
An 8-bit field which is used to set the base frequency for the device. This field sets the base frequency
for all transmit, receive and boost mode channels. The Base Frequency is determined using the
following equation:
Base Frequency (MHz) = 409.6 MHz + (Base Frequency Channel * 12.8 MHz)
5.2.5 Transmit Frequency Channels
4 16-bit fields (13 used) representing Transmit Channels A, B, C, and D each from 0-8000 spanning 50
MHz of bandwidth in 6.25 KHz slots. The end point device transmits on all N channels in
pseudorandom pattern, if a single channel is selected, transmitter uses single channel. The channels
actually enabled for use are selected in the Transmit Channel Mask field. Channel A is always
selected. The Transmit Frequency is determined using the following equation:
