EZL-50 / EZL-50L / EZL-70 / EZL-410 / CSE-M73 5V should be supplied to Vcc.
EZL-80 / 80c / EZU-100 / CSE-M32 / M53 / EZU-100 / CSW-M83 3.3V should be supplied to Vcc.
EZP-250 2.7 ~ 5.5V should be supplied to the Vcc.
Rest of the products including external and board types. A dedicated DC 5V adapter should be used.
At this time, the outside of the terminal should be connected to the (-) polarity.
Please pay attention to the fact that free service will not be provided on any problem caused by wrong connection of power source.


2. Fine connection of Ethernet cable


-Choose a right cable in your situation referring to the below tip.
How to make UTP cable?



Direct connection with a PC Use a crossover cable
Connection to a HUB Use a straight(1:1) cable

-EZL-50, 50L, 60, 60L, 70, 200L are used as 10Base-T(10Mbps).
So they don't work at 100Base-T(100Mbps) line.
-You can check the normal state of cable connection by observing if the link LED is turned on.
-If the link LED is off, check the connection of the cable first, and if the cable is fine,
check the condition of the link LED after putting the ezTCP/Ethernet product to the ISP mode.
-If the link LED is only turned on while the ezTCP/Ethernet product is in the ISP mode, the firmware has chance to be wrong so we recommend that you upload it again.
-If the link LED is not turned on even in the ISP mode and the cable is fine, the product needs repair.
In the situation, contact us without hesitation.


3. Stable supply of power.


-In general module type products are manufactured as an insertion to another product.
Those modules do not influence other products.
However, they need a stable supply of power for correct operation.
Contact us if you want to obtain further detail information in this regard.


4. Caution of Electric shock.


-Pay attention to use of ezTCP. As almost electric device, ezTCP has limit of tolerance for the shock.
Especially, module and board type products which don't have the case need attention more.
