Phone: [phone] - Fax: [phone] - Web: www.ctiautomation.net - Email: [email protected]

1.1 Overview
This is the wireless unit that can be communicating with terminal equipment via 2.4GHz SS
radio (not necessary the license).
It is appropriate to a communication system for monitoring temperature, electric power and
so on.
1.1.1 Features
Appropriate to high-speed data communication
It is appropriate for the high-speed data communication with 134kbps wireless communication
speed.
Appropriate to save wiring and to save construction
Reduce cost for layout change of equipment and machines and for cost of cable construction in
the place where it is difficult to wire.
No distinction between Master and Slave
It is possible to distinguish between Master and Slave by setting of the Unit No.; therefore you can
purchase without caring difference of master and slave.
RS485 type is provided
By using RS485 type, heretofore, RS232C-RS485 converter has been needed to connect with
RS485 communication equipment, but the converter is not needed and it is possible to connect to
RS485 communication equipment directly.
The main unit and also setting tool can be easily operated
For 1:1 topology (1 unit of master and 1 unit of slave), it is possible to start communication by
setting the main units only. And in 1:N topology (one unit of master and multiple unit of slaves), we
prepare setting tool (Control Configurator KR) that is easy to set and operate. This software loads
the test functions so that it is convenient when installing wireless units. In addition, it is possible to
download this software from our company’s web site.
Wireless repeater function
Communication distance between master and slave is 250m*. It is possible to elongate the
communication distance by repeater function that is loaded in this unit. (It is possible to set max 8
units between master and slave) * But straight distance with a good view.
Maximum connectable numbers of terminal equipment are 254
For RS485 type, it is possible to connect max 99 units of slave to one unit of master, and to
connect 31 terminal equipment to one unit of slave. Total connectable numbers of terminal
equipment are 254. In I/O type, it is possible to connect totally 99 units of slaves and terminal
equipment.
I/O communication and serial communication (RS232C) are possible at the
same time
For I/O type, it is possible to perform serial communication (RS232C) with performing input/output
(I/O) communication at the same time.
For 1:N topology, all models can be used in mixture
For 1:N topology, when MEWTOCOL is used, RS485 type and I/O type can be used in mixture.

1.1.2 Communication style
3 kinds of communication system are possible.
1:1 topology
・ It is the system with 1 unit of master and 1 unit of slave.
・ In serial communication, the communication protocol (serial communication protocol) of the
connected equipment is not specified.
(Except the case that communication between terminals is executed with start character ">".
Refer to the note.)
・ Setting only the main unit can make it usable.
Note: When communication between terminals is executed with start character ">", it
is impossible to communicate correctly, because it is identified the command
for wireless unit.Change start character by setting tool. It is necessary to
change not only master but also slaves.

・ For I/O type, it always performs wireless communication from master to slave. (Polling)
Due to this, it outputs the communication error when wireless communication is cut off
continuously. (Communication error is output after about 30 sec. with no communication.)
・ For I/O type, input signal is communicated to the output terminal of the same number of the
connected slave. (Example: Input for IN1 in master is output to OUT1 in slave, input for IN2 in
slave is output to OUT2 in master.)

1：1 topology with repeaters
・ It is the system with 1 unit of master and 1 unit of slave and repeaters between master and slave.
・ Max. 8 repeater stages are possible (between master and slave)
In serial communication, the communication protocol (serial communication protocol) of the
connected equipment is not specified.
(Except the case that communication between terminals is executed with start character ">".
Refer to the note.)
・ It is set by using setting tool.
Note: 1.When the repeater stages are increased, the communication time will be long.
Consider about the response time. And wireless unit used as a repeater
cannot connect terminal equipment.
2. When communication between terminals is executed with start character
">", it is impossible to communicate correctly, because it is identified the
command for wireless unit.Change start character by setting tool. It is
necessary to change not only master but also slaves.

■I/O type
・ For 1:N topology of I/O type, it is impossible to control I/O of slave by using I/O of master.
Sending the commands from the computer or PLC that is connected in the upper level controls
I/O of master and slaves. (Except [I/O] 1:N topology for report)
・ For 1:N topology of I/O type, wireless units are located as same as the MEWTOCOL accepting
equipment. Therefore when equipment for MEWTOCOL is connected to slave, it is necessary to
change the unit number.
・ For 1:N topology of I/O type, you can select either “Event” that perform the wireless
communication when there is the data communication from upper level, or “Polling” that always
perform the wireless communication in series from a master to slaves that is connected.
・ For Event, even if the input signal is input from the upper level to the slave as long as information
on the slave is not inquired, information is not transmitted. It is possible to communicate at the
shortest time if communicate only when it is necessary. Please select this system if you use data
communication mainly, and want to use the output signal possibly.
・ For Polling, master has I/O information of all slaves, therefore, if you often use I/O communication
than data communication, please select this system. But, it takes time to check the state of all
slaves if there are a lot of slaves. For polling, it outputs communication error when wireless
communication is cut off. (Communication error is output after about 3 times of polling time. But it
is less than 30 sec., it outputs after 30 sec.)
・ For 1:N topology for report function, basic performance is the Polling of 1:N topology, but it is the
communication protocol that can reflect the input of slaves to the output of master, without
connecting the computer or PLC in the upper level. And, the input to the master can be reflected
to the output of the same number of all slaves. It is the most suitable function for trouble report or
report reset application of equipment. In addition, it can’t perform I/O communication and data
communication at the same time, please use only I/O communication.

1.3 Restrictions
1.3.1 Communication restrictions for wired side
Delimiter time of data by wired side
Wireless unit doesn’t determine an end of wired data by control code such as “CR”, and determine
by a blank time.
At initial setting, if there is the blank time for 10 characters, it is determined as the end of wired
data and wireless unit starts wireless communication. Therefore the data with blank more than the
time will be interrupted. Moreover, if the blank time between primary data and next data is less
than the time, two data are judged as one datum, and it is not likely to send correctly.
Connecting direction of master and slave
(1:1 topology with repeaters, 1:N topology)
Please let the master side as command sending side, and the slave side as response sending side
because it is a communication procedure for requiring the command response. Cannot
communicate in inverse combination. And cannot use in communication system that both master
side and slave side sends the command.
Sequences of command and response
When using sequence of sending successive command, make the sequence that it send the next
command after receiving a response to the former command. When timeout period is set, it is
necessary to consider wireless communication time. Wireless communication time may become
long according to the surrounding communication environment, therefore there is a possibility that
collision of command and response is occurred when it send the next command after a fixed time
from the former command.

Input signal time
For 1:1 topology and 1:1 topology with repeater of I/O type, input signal and output signal are not
always monitored, and only monitored when immediately before transmitting, and then
communicate the information. Therefore, if the input signal is shorter than the polling time, it may
not communicate to the output. To communicate reliably it is necessary to keep the input signal
longer than the polling time.
