INSTALLATION AND SETUP
Another method for using the RS-485 COM1 port as an RS-485 serial link (remote) is to use Opto 22 I/O units
installed with a SBTA, as illustrated in Figure 3-21. This allows you to accommodate your own installation
practices, application requirements, and cables. Simply mount your I/O units throughout your installation and
daisy chain communication cable between them. Refer to the
Mistic 200 Systems
Installation Guide
for more
SBTA details.

specifications in
