Chapter 1: Features and Functions
JW-21MN is a ME-NET module for JW20/JW20H/JW30H. Using this module, you can construct an MENET combining various FA equipment such as personal computer and robot.
Using this module, you can easily transmit and receive ON/OFF signals and data with devices that
have a network module which is compatible with the ME-NET specifications.
[When you want to install a JW-21MN in the JW30H, make sure to select one that is compatible with
the JW30H. (See precautions inside the front page of this manual.)]
(1) Data link function
- Send and receive an ON/OFF signal (relay link) and data (register link)
between modules on the ME-NET.
Number of linkage pointsLinkage method
Relay link 2048 (256 bytes) in total
Register link 2048 bytes in total
*The amount of data that can be transmitted by one station is a maximum of 1024 bytes,
including both relay link and register link.
- In order to use memory effectively, the JW-21MN has a memory save function. When this
function is enabled, it only needs to receive the specifically required data.
.
(2) Computer link function
- Triggered on commands (instructions) from a host computer which has a network module
compatible with the ME-NET specifications, the JW-21MN starts reading and writing the memory
in the JW20/JW20H/JW30H.
- After an instruction is received from the host computer, the JW-21MN returns a response.
Therefore, the host computer is required to create an application program. For detailed
description of how to transmit instructions and receive responses, see the instruction manual for
the host computer.

Do not connect the ground terminal of the power supply module together with other equipment's
ground lines. Make sure to provide class-3 grounding.
When the JW-21MN is used without connecting a class-3 grounding, malfunctions by noise may
occur.
Communication cables should be arranged as far from any high voltage lines and strong power
lines as possible. Do not lay the communication cable parallel or proximate to these lines.
2-1
Communication cables should be laid from the master station to the slave station one by one.
Multiple wiring from one point or wiring without terminators may cause communication errors.
Joint using a
connector

2-3 Treatment
For ventilation, holes are provided in the cabinet to prevent a temperature rise. Do not block the
ventilation holes. Good ventilation is necessary.
Never allow a liquid such as water and chemical solution and a metallic object like a copper wire
inside the JW-21MN to avoid a possible hazard. Otherwise, it may be a cause of machine trouble.
When a trouble or abnormal condition such as overheat, fume, or smoke is met, stop the operation
immediately, and call your dealer or our service department.
2-4 Static electricity
In extremely dry circumstances, the human body may have excessive static current. This excessive
static current may damage parts in the JW-21MN's PC board. Therefore, prior to accessing the JW21MN, touch your hand to a grounded piece of metal to discharge the static current in your body.
2-5 Maintenance
Use a clean, dry cloth when cleaning the JW-21MN. Do not use volatile chemicals such as thinner or
alcohol as it may result in deformation and color fading.
2-6 Allocation of relay number
JW20/JW20H/JW30H which installs JW-21MN are laid out 16 points to the JW-21MN as a relay
number. These 16 points are dummy area which is not used in JW-21MN.

Slightly widen the external conductor of the
coaxial cable, which is crimped to a contact on
the internal conductor, in order to smoothly enter
the shell inside the external conductor. Press in
the external conductor end of the coaxial cable
to just before the crimping part of the shell and
put the sleeve into the crimping section. Then
press in the coaxial cable until a “click” sound
can be heard. Confirm that the contact end point
touches your finger cushion.

Insulation test of shell and contact
Using a tester, check the conductivity
between the internal conductor and
the external conductor in the
connector. When the indication of
the tester shows ¥ ohms, the
insulation is appropriate.

Chapter 7: Wiring Method
7-1 Cable trunk and branch lines
On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched
from the trunk with a "T" shape are called branch lines.
400mm max.
The length of branch lines branched from the trunk should be within 400 mm.

7-2 Relaying of trunk cables
To relay trunk cables, use the straight joint (ME-JJ-01).
ME-JJ-01
Relaying of trunk cables should be limited to indispensable cases only. Inadvertent relaying of trunk
cables may cause a communication fault such as a weakened signal level due to contact resistance
in the junction connector (straight).
Junction

7-1
7-3 Cable wiring procedure in control panel
(1) Fixing of the cable
In order not to put any force on the cable and the
JW-21MN, fasten the cable to an line nearby input of
a control panel or a "T" branch point to the JW21MN using saddles etc.
(2) Extra length of cable
Provide an extra length of the cable of 2 to 3 m
inside a control panel for easier processing of the
cable end and easier wiring when changing module
positions.
7
(3) Connection to the JW-21MN
The connector to the JW-21MN should be turned
right to secure locking, not merely inserted.

When the connector touches with a high voltage
section or external enclosures, communication
errors may occur. Make sure to install an insulation
cover.

(insulation cover)
(5) Grounding of power supply module (JW-22PU/31PU)
Make sure to use a class-3 grounding to connect the GND terminal of the power supply module.
- If the power supply module is not grounded, the JW-21MN cannot conduct with the ground after
turning "ON" the shield ground switch.

(6) Bending radius of the signal cable should be less than 45 mm (outside).
R45 or larger
- Specification of the cable manufacturer is that bending radius should be 6x of the cable finish
outside diameter (approx. 7.5 mm).
(7) When you install morethan one module of the JW-21MN into one programmable controller, we
recommend to put identification tag on each dable.
7
(8) Before transport or store the JW-21MN, put a protection cap on the connector of the JW-21MN.
7-3
7-4 Waterproof and insulation processing of connectors
In order to prevent water intrusion into the "T" branch connectors and the straight connectors, we
recommend to wind a self-adhesive tape and provide waterproof processing for them. For insulation
purposes, cover these connectors with jackets.
(1) "T" branch connector
To wind a self-adhesive tape, cut the tape at about 10 cm each and start winding from position .
Start winding cut tapes from and as well.
Self-adhesive tape

(2) Straight connector
To wind the self-adhesive tape, cut the tape at about 15 cm each and start winding from position
.
Self-adhesive tape
Straight
Remarks
Prior to adhering the tape, clean the surface of the connectors and stick the adhesive side of
the tape on the connector surface. Wind to lightly spread on the connector surface, and overlap
with the next wrap to half of the tape width. Wind the tape for each wrap evenly so that the
connector metal portion is completely covered with the tape.
Be careful not to excessively stretch the tape.
7-4
7-5 Wiring of cables at outside control panels
Do not bundle the coaxial cable (the trunk and branch lines) together with power cables, and
separate from power cables at least by 100 mm. Do not put the coaxial cable into a power line wired
duct. The best way is to put the communication line in an independent duct.
Be careful that the coaxial cable does not receive any load by laying under a heavy weight such as
other cables.
When other cables run in the same duct as the coaxial cable, run the coaxial cable on the top
position.
Do not run the coaxial cable outdoors as it may cause damage to the JW-21MN due to inductive
lightning or atmospheric charge during lightning.
7-6 Check after wiring
Check the items below after completion of wiring.
Check contents
1 The recommended connector types are used.
7
2 The connectors are securely locked.
3 The connectors are insulated by "T" jacket or "L" jacket.
4 The recommended coaxial cable type is used.
5 Curved radius of the coaxial cables are more than 45 mm.
6Noheavy load is on the coaxial cables.
The coaxial cable is not bundled with a power line cable.
7
(Away from power line cables more than 100mm.)
8 Length oh branch lines is shorter than 400mm.
9 Total length of the cable is less than 1km.
Settings of the termination resistance switch and the shield ground switch are as
10
per the drawings.

(3) Notes
When adding a communication station, follow the items below.
No.
Branch from the trunk cable.
1
Don’t use the same station number
2
twice.
Check the termination resistance
3
switch.
Provide extra length for the
4
expansion cable.
Do not exceed the 1 km limit for total
5
length of the cable.
Change the layout drawing for
6
installation.
Do not overlap with any PC’s
7
communication area.
Set the parameter memory of the
master station and that of the newly
8
added station.
Item Reason
Another branch line from a branch line may not give
appropriate communication by reflection wave.
The use of the same station number twice may cause
communication errors.
When the newly added station becomes a termination of
the circuit, change the setting of the LT switch.
Have enough cable length in order to provide easy wiring.
Longer wiring may cause communication error by signal
attenuation.
Maintain the added work data for future maintenance use.
When the communication area or the flag area of the
added station overlaps with other addresses in use,
communication errors may occur.
Without setting the parameter memory of the master
station and that of the slave station, the added station
cannot communicate.

Chapter 8: Memory Address on the ME-NET
The ME-NET employs a system for addressing individual memory banks in all of the connected
equipment by allocating address throughout the ME-NET. Therefore, the top address in any link area
which will contain in the data link parameters and memory addresses used for computer link
instructions must be a valid memory address in the ME-NET.
The relationship between memory addresses in Sharp PCs (JW20/JW20H/JW30H) and those on the
ME-NET are shown below.
8-1 Memory address for data links
The memory addresses(8) on the ME-NET correspond to the file addresses(8) in a Sharp PC (JW20/
