*NOTE: Onput signal levels between pins 3/4 and 13/14, will influence each other because these pins are connected in paral-
lel. When a 2nd 600 Ω impedance device is additionally connected, adjust the 2nd device to the specified signal levels
for the output (pins 3/4 and 13/14) signal levels of the connected 600 Ω impedance device (reception).
† Input signal from pins 1/2 or 11/12 are acceptable only when transmitted with the SEND signal from 5 or 15, respec-
tively.
