connecting it to the mains supply. Simply use ultra
low power from the standard RS232C/V.24 data and
control signal voltages. The unit fully operates even
if only Transmit Data and Receive Data are
connected—no control signals are needed. Both
positive and negative signals are generated in
compliance with RS232C/V.24 standards, regardless
of constantly high or constantly low Transmit Data.
Low transmit level minimizes cross-talk onto adjacent
circuits within the same cable. Data is transmitted
and received at a balanced impedance, ensuring
excellent immunity to circuit noise.
The Mini Driver MPI is couples to the telephone line
through isolation transformers which, in conjunction
with electronic circuitry, protect against AC or DC
overvoltages. The transformers are rated at over
1,500V RMS, making the line driver suitable for
connection to local circuits provided by most
telephone administrations.
