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.
