passed through a low-pass filter (IC107) with a cut-off frequency of 1500 Hz. The purpose of this filter is to

round-off the edges of the square wave input.

17.1.13 MODULATION INPUT. The data modulation for the DATAFLOW RTU is Bi-Phase M. The received

data from the RF board is first run through a low-pass filter (IC107) to clean-up the wave. This signal is then

squared-up by a comparator (IC107). This signal is then finally decoded by a software decoder in the

microprocessor.

17.2 See the applicable RITRON DTX manual for the RF board theory of operation. When using the DTX

manual in support of the DATAFLOW RTU only the RF portion is valid. Disregard all references to the DTX

control board.
