3.2.3. RS-422 Connection between DT-105/110/203X, and a SCB41 OMRON
connection kit.
In a RS-422 connection the line length must not surpass 1000m, without amplifiers
It is necessary to use shielded pair cable and to connect, between the display and the
converter, the screen to pin 9 in the DB9 connector. The transmission line must be placed away
from high power lines. Branches from the network to the displays must be as short as possible.
Resistors of 120 Ohm must be set at the end of the line to ensure that the network is in good
working order.
In connector DB9 there is enough space to set the resistance together with the
connection.
