This manual describes the installation the and specifications of the 485ADP.
For details on wiring (including use of terminal resistor and preparation of cable) with communication equipment,
system configuration and communication setting, and program examples, refer to the "FX COMMUNICATION USER'S
MANUAL".
1. Outline of Product
The 485ADP is an insulated RS-485 communication adapter with an European type terminal block.
Connected to the main unit of the FX Series PLC, it enables signal exchange between the PLC and
equipment via an RS-485 port.
2. Communication Functions and Applicable PLC
(Available in indicated version or later)
3. Installation
Caution
• Use in the environments specified under the general specification in the manual.
Do not use the product in environments with excessive or conductive dust, corrosive or
flammable gas, oily smoke, moisture or rain, excessive heat, regular impact shocks or
excessive vibration, as it may result in electrical shock, fire, malfunction, damage or
deterioration on the product.
• Make sure to shut off the power outside the product before installing or wiring it.
Otherwise, electric shock or serious damage to the product may occur.
• Never drop wire chips or shavings into the vent slits when drilling screw holes or performing
wiring, as they may cause fire, breakdown, or malfunction.
• Securely install the 485ADP to the designated port.
Poor connection may cause malfunction.
3.1 How to Install to FX Series PLC
Installation to FX1S/FX1N/FX2N
Turn OFF the PLC before beginning any work.
1) Remove the panel cover from the top face of the main unit.
2) Take off the resin cover from the left side of the main unit.
3) Install the following board to the port on the main unit.
4) Fix the above board using the M3 screws supplied.
Tightening torque: 0.3 to 0.6 N·m
5) Connect the in-built cable of the 485ADP to the port on the
board from the left side.
Installation to FX0N/FX2NC
Turn OFF the PLC before beginning any work.
1) Remove the cover of the port for a special adapter provided on the left side of the main unit.
2) Connect the in-built cable of the 485ADP to the port for a special adapter.
3.2 How to Install to Panel Face
Direct installation to the panel face
Directly fix to the panel face using 2 sets of a screw (M4), a spring
washer, and a flat washer in the mounting holes.
Tightening torque: 0.7 to 1.0 N·m
For the pitch and positions of mounting screw holes, refer to the
external dimensions.
Mounting on DIN rail
Fix the 485ADP to the DIN rail, DIN46277 (35 mm (1.38 inches) wide).
Dismounting from DIN rail
Slightly pull down the DIN rail mounting clip using a tool such as a
slotted screwdriver. Pull down the clip further, and the rail will be locked
with the clip left open.

2) Take off the resin cover from the left side of the main unit.
3) Install the following board to the port on the main unit.
4) Fix the above board using the M3 screws supplied.
Tightening torque: 0.3 to 0.6 N·m
5) Connect the in-built cable of the 485ADP to the port on the
board from the left side.
Installation to FX0N/FX2NC
Turn OFF the PLC before beginning any work.
1) Remove the cover of the port for a special adapter provided on the left side of the main unit.
2) Connect the in-built cable of the 485ADP to the port for a special adapter.
3.2 How to Install to Panel Face
Direct installation to the panel face
Directly fix to the panel face using 2 sets of a screw (M4), a spring
washer, and a flat washer in the mounting holes.
Tightening torque: 0.7 to 1.0 N·m
For the pitch and positions of mounting screw holes, refer to the
external dimensions.
Mounting on DIN rail
Fix the 485ADP to the DIN rail, DIN46277 (35 mm (1.38 inches) wide).
Dismounting from DIN rail
Slightly pull down the DIN rail mounting clip using a tool such as a
slotted screwdriver. Pull down the clip further, and the rail will be locked
with the clip left open.
