RS-485 Port
An RS-485 non-isolated port uses a 3-position, screw
terminal connector and always operates as COM2.
Use shielded 18-22 AWG wire for this connector (refer
to the Telecommunications Industry
Association/Electronic Industries Alliance
[TIA/EIA-485 standard]). As shown in Table 4, the
screw terminals (from left to right) are shield, plus (+),
and minus (–).
USB Port (FX60 only)
A single USB port is on the top of the FX60.
Note: The USB port is for future use. Do not use the
port at this time.
