GENERAL POINTS
An RS 485 link is used to connect up to 31 ATyS with a
PC or a PLC over a distance of 1500 meters, using
©
JBUS / MODBUS protocol.

Recommendations
You should use a shielded twisted pair (LIYCY type). In
an interfearence environment or large network (in terms
of length) we recommend the use of 2 shielded pairs
(type LIYCY-CY). In this case, one pair is used for the
+ and the –, and another pair, where the 2 wires are
short-circuited, for the 0 V.
A repeater (1 channel) or an arrestor (4 channels) should
be used if you intend to exceed the distance (1500 m)
and / or maximum number (31) of ATyS. Please contact
us for more information.
A 120 ohm resistance (found on the RS485
optional module) must be fixed at both ends of
the link.
