7.3.2 RS-485

An RS485EXT box is required to convert the RS-232 signals to RS-485. Using a flat-bladed 
screwdriver press firmly in the small square slot to open the wire slot. Insert the end of the wire 
into the wire slot. Remove the screwdriver to close the wire slot. Repeat with the other wires.

TIP:
Wires with ferrules can be pressed firmly into the wire slot. You do not need to open it first.
