■
Usageprecautions
1
Battery
The transmitter comes with two 1 / 2AA size lithium metal batteries (non-rechargeable).
Please dispose of used batteries in accordance with laws and regulations relating to the
environment and safety regulations in your area. Do not attempt to recharge these batteries.
When replacing the battery, confirm that the battery is of the recommended or applicable
type, and confirm that the battery is inserted while correctly aligning the electrodes in
accordance with the procedure described in this manual and the indications on the product.
Please refer to the instruction manual of the battery manufacturer for guidelines relating to
specific battery applications, safety and disposal.
・Please confirm that all batteries are inserted with the electrodes correctly aligned.
・Do not store batteries in locations subject to direct sunlight or rain.
・Do not allow the battery to be heated or incinerated.
・Do not intentionally discharge the battery.
・Do not allow the battery to be short-circuited.
・Do not disassemble the battery, subject the battery to excessive pressure, drill holes in the
battery or allow it to be deformed.
・Take precautions so that the battery is not accidentally swallowed. Store the battery in a
location out of the reach of children.
・Do not allow the battery to become wet.
2
Glasswindow
The transmitter has a glass window. In the case the glass window should happen to be
broken, handle the product carefully to prevent injury.
3
Installation
Please confirm that the following guidelines are strictly observed at the responsibility of the
person performing installation work to ensure that the product functions properly.
・Please install while placing the interface at an adequate distance from electrical noise
generation sources such as transformers or servo amplifiers.
・Connect all 0V / ground connections to a central ground terminal on the machine.
(The grounding and shielded cables of all devices can be connected to ground.)
This is extremely important, and failure to do so can cause the generation of an electrical
potential between the product and ground.
・Connect all shields as indicated in the user's guide.
・Place cables at an adequate distance from large-current cables such as motor and other
power cables as well as high-speed data cables.
・Try to keep cable lengths as short as possible at all times.
4) Product usage
Use of this product in a manner other than that specified by METROL may cause a decrease
in the guaranteed performance and functions of the product.

Basicspecification
The transmitter communicates with the receiver using 2.4GHz ISM band.
The receiver receives touching signal, battery alarm signal and communication alarm signal from
the transmitter and outputs the decoded signals to CNC controller through the cable.

Software specification
3-1
Transmitter
Transmitter has 3 modes.
1
Sleep mode
When M code (power ON signal) does not exist, transmitter operates in the Sleep mode to
suppress power consumption.
Transmitter periodically attempts to make communication witht the receiver.
Transmitter and receiver communicate with each other and exchange data every 14 - 27
seconds, if the communication is possible.
In this communication, transmitter sends the battery alarm signal to the receiver while receiver
sends the channel information to transmitter.
In case it stays incommunicable for 30 seconds or longer, it changes channels automatically.
When the transmitter is incommunicable with the receiver, it attempts to communicate by
changing channels.
Once the communication is established, its functions will be recovered within 4 seconds.
2
Measuring mode
Once the transmitter received M code (power ON signal) from the receiver, it enters Measuring
mode.
In this Measuring mode, transmitter communicates with receiver every 2ms.
In case the communication is not successful, the transmitter immediately changes channels.
The LED of the transmitter turns on when the contact touches a workpiece.
The transmitter enters Sleep mode automatically if it stays incommunicable for 1 minute.
Even in this case, the transmitter returns to Measuring mode soon after M code (power ON
signal) is sent from the receiver.
3
Matching mode
This mode is the initial setting.
In this wireless communication system, the transmitter stores ID number.
By using ID number, it performs matching with the receiver so that the receiver stores ID.
Once ID number is stored in the receiver, it performs communication exclusively and is never
affected by any other communication systems.
This ID number (transmitter) is stored nonvolatile.
Note: Matching is necessary every time transmitter is exchanged.

8
www.baysupply.com
3-2
Receiver
Receiver has 3 modes.
1
Sleep mode
Receiver watches 2400-2480 MHz range anytime and find out the empty channel.
It waits until M code (power ON signal) is sent, continuously sending radio wave state (empty
channel information) to the transmitter.
If the communication with the transmitter is successful, the Com. LED (Green) of the receiver is
turned on.
If the communication cannot be achieved, the Com. LED (Green) flashes.
In the Sleep mode, no alarm signal is output to a control device even if the communication is
abnormal.
Batt. LED (Orange) flashes or lights up when the battery runs out, but the receiver does not
output alarm signal.
2
Measuring mode <After receiving Measuring ON Signal (M code)>
After the receiver sends M code (power ON signal) to the transmitter, receiver and other system
enters the Measuring mode.
Then it waits for the sensor ON signal from transmitter. At the same time, it prepares for
sending all alarm signal to control device.
All LEDs become active.
*
* It depends on battery state at the time of input of M code, and is effective only for 10 seconds.
When M code (power OFF signal) is sent from a control device, receiver transmits it to the
transmitter. Then both receiver and transmitter enter the Sleep mode from the Measuring mode.
3
Matching mode
This mode is the initial setting.
The receiver stores the ID number of transmitter in order not to be affected by any similar
signals.
This ID number (transmitter) is stored nonvolatile.
Note: Matching is necessary every time the transmitter is exchanged.

Matching transmitter and receiver
It is necessary to match the transmitter and receiver when first installing the system.
Matching is also required when replacing either the transmitter or the receiver.
Matching can be performed anywhere within the range of movement of the system.
1
Receiver matching procedure
1)
Remove the cover of the receiver.
2)
Switch the parameter switch #8 (DIP switch) on the receiver to OFF.

Transmitter matching procedure
1)
Remove the cover of the transmitter and affix it again (Restart the transmitter).
①Removethebatterycover

②Reinsertthebattery ③Affixthebatterycover
2)
Matching is completed when the Batt. LED lights.
3
Matching mode completion procedure
1)
Switch the parameter switch (DIP switch) #8 on the receiver to OFF.
OFF
2)
Complete the matching procedure by attaching the receiver cover.
Note : The matching procedure is performed to record the transmitter ID number in the receiver and
prevent interference by other radio signals.
Once the matching procedure has been performed, further matching is not required provided
the transmitter is not replaced (or repaired).
