RI/O Receiver Install (480E/485E/485K &
685E/785E/785D/785K)
The J89OlJ892 RI/O receiver is used with 800 Series I/O in a 480El485Ei485K
system. In this section, you will be setting J890/892 RIO adapter, DIP switch set-
tings for Drop Address and Port Configuration and mounting.
Figure 33 shows DIP switch locations on J890/892 modules. Note the J890 RI/O
module has only one DIP switch which is used for the Drop Address. The J892
RI/O (ASCII) has both a Drop Address DIP switch and a Port Parameters DIP
switch. Because the switches are on the rear of the units, you must set them be-
fore installation in a rack.

The P89O/P892 RI/O receiver (with built-in power supply) may
be used instead of the J89O/J892 RI/O receiver. Please refer to
P89O/P892 RI/O Processor Installation Instructions (Modicon Part
