Installation
1. Set each IC-485S / IC-485SI’s configuration switches
according to the information provided in the Switch
Configuration and Operating Modes sections.
2. Plug the IC-485S / IC-485SI’s DB-25 female connector into
the computer’s RS-232C port.
3. Connect the IC-485S / IC-485SI units to each other:
 Use two or four wire twisted pair cable in a reverse or
straight through configuration according to the information
provided in the Switch Configuration and Operating Modes
sections.
 For the IC-485S, you may use either the RJ-11 telephone
socket, or wire directly to the Terminal Block (See the
Terminal Block section for pin assignment details).
 For the IC-485SI, you must ground the device by
connecting a grounding wire from the Grounding Tab to the
grounding source.
Note: 1. When tightening the terminal connector screws it is
recommended to use a Phillips PH1 Screwdriver.
2. Over-tightening the terminal connector screws may
result in damage to your IC-485S or IC-485SI and
difficulty loosening the screws.
4. Power on the computers. The units are now ready for
operation.
