DekoCast RS-422 Automation Control
Your DekoCast system comes equipped with two industry standard RS-422 ports that can be used
for connecting to an automation system or for other control applications. These ports are labeled
as RS-422A and RS-422B on the back of the DekoCast chassis. Refer to Figure 3-2.
The pinouts for the RS-422 ports for automation control are shown in Figure 3-8.
These RS-422 ports will appear as standard COM3 (RS-422A) and COM4 (RS-422B) ports that
can be selected from the DekoCast Central Application or from a custom application that is
written for your DekoCast. Please refer to the DekoCast User documentation provided on the
application CD for more information.
