Note: For a true RS422 connection, you can use an adapter made by “KK Systems” (Part
Number K422-99). This adapter connects to the RS232 port on the PC and provides an
RS422 connection on the other side. To connect the K422-99 to the NUGGET, use a
standard RS422 cable (See wiring of the standard RS422 cable). A true RS422
connection allows for a better connection and longer cables.
