ASYNC RS-232 TO 2-WIRE RS-485 CONVERTER
4.2 Connection to the RS-485 Interface
To function properly, the Converter must have one
twisted pair of metallic wire. This pair must be “dry”
(unconditioned) metallic wire, solid conductor,
unshielded twisted pair, between 19 and 26 AWG (the
higher-numbered gauges may limit distance somewhat).
We recommend using Category 5 solid 24 AWG cable.
For your convenience, the Converter comes with
either an RJ-45 connector or a terminal block on the
RS-485 side.

ONNECTING VIA THE
RJ-45 I
NTERFACE
The RJ-45 versions of the Converter use an RJ-45
connector on the RS-485 side. This connector is
prewired for a standard telco wiring environment.
The signal/pin relationships are shown in
Figure 4-1
