Each these interfaces works with 2-wire line 4-wire transmission technology (RS-
485).
(female multipoint connector terminals z6, z8, z10 and z12 see page 22).
. The required terminating resistors are automatically enabled (you not have to
check the 'Terminated' option).
ELAN LEFT refers the settings for the left bus
(female multipoint connector terminals b6, b8, b10 and b12 see page 22).

A 2-wire cable usually chosen because it's the only one that enables bus configuration -
with several participants the same bus cable.
The bus cannot function properly without terminating resistor because the reflection at
each end the wire. The integrated terminating resistor must
be switched for the first and the last participant the bus cable (option: 'Terminated'
).
ELAN RIGHT refers the settings for the right bus.
Transmission distances 1000 the use booster require 4-wire transmission tech-
nology. All other bus participants must set ‘Not terminated’.Page 97
