1. Introduction
1-1 Greeting
Thank you very much for adding -LEｔ option to our product.
We have done our best for our quality control of our products. Please handle this unit properly
according to this instruction manual so that you can use the full capacity of this unit and operate it
safely and smoothly in high efficiency for long. If, however, you find any doubtful or unknown point or
omission in the instruction manual, please contact us.
1-2 Summary of –LEt option Greetin
-LEt option comes with the digital communication interface for Matsusada power supplies that is
directly connected to the network to connect Matsusada power supplies. Therefore it enables to
locate the power supply on the network, and no separate interface is needed to control it.
1-3 LAN connector
Connect with RJ45 (10BASE-T, 100BASE-T)
1-4 Network setting
Follow the instruction of Network administrator to set the LAN setting of the unit.
Default setting
IP address 192 168 010 001
Subnet mask 255 255 255 000
Default gateway 000 000 000 000
Remote port number 10001
*The fixed remote port number is 10001.
1-5 Precautions for network setting
The -LEt option employs Xport® manufactured by LANTRONIX for the LAN module. The –LEt
option setting of the Matsusada power supply is made at the power supply unit itself.
If you use “Web Manager” in Xport® for changing, the configuration setting through the power
supply will not be reflected correctly.
Note that we do not provide any support for the setting change using “Web Manager” or procedures
of configuration and operation other than those described in this instruction manual.

4. LOCK switch (Hold down)
Set network address will be registered on power supply itself.
(*Restarting of the power supply is required to effect registered setting. Setting will be reflected
when the power supply is turned on next time)
After registered, next tim e
pow er supplies are turned
on, the registered info will
be reflected.
Hold down LO C K
It takes more than ten seconds to complete the startup because the setting is
written to the LAN module in turning the unit on. Therefore, if you turn the
unit OFF before the startup is completed, the writing will not be finished
normally, and the communication may not work properly.
In this case, reset it to the factory default or set and write the other value
instead of the IP address setting. After that, the setting is to be carried out
again. Once you have written the other value, the setting will be performed
normally.
