Let’s look at the ISP mode
In System Programming (ISP) mode
Q: What is the ISP mode?
ISP mode is one of states for upgrading firmware of ezTCP series. This mode is also used about solving problem with password for most of ezTCP. When you’ve forgot the configured password on your ezTCP, ISP mode will help you. In ISP mode, password and an option accessing to its configuration tool (ezManager / ezConfig) do not working.
Q: Then, can I use this mode all the time?
The answer would be No!
The TCP connection or data communication is impossible in this mode. So, you should use this mode when you are faced with above two situations.
Q: How can I get enter the mode?
The ways could be different on their types.
Pull-down the ISP- pin and then, reset or resupply the power to the product.
In case of using evaluation board, connect the jumper to the ISP position and reset or resupply the power.
Place the JP1 (ISP jumper) to ISP location for making a short circuit of those two pins. And then, reset or resupply the power.
Connect the ISP jumper (EZL-70: JP1, CSE-M73: JP6) for making a short circuit of those two pins. And then, reset or resupply the power.
Press the ISP button by RJ45 connector over 3 seconds in normal mode. Or, resupply the power while pressing the button.
If EZL-200L is in ISP mode, the STS LED will be blinks very quickly.
Resupply the power while pressing the ISP button located by RJ45 connector.
If EZL-200F is in ISP mode, the STS LED will keep on.
Pull-down the ISP- pin on JP1 and then, reset or resupply the power.
In case of using evaluation board, place the jumper on JP5 to ISP location and reset or resupply the power.
EZL-300S/400S
Both products don’t have ISP mode. The firmware download will be implemented in telnet connection.
Pull-down the ISP- pin and then, reset or resupply the power.
In case of using evaluation board, locate the jumper on JP5 to ISP location and reset or resupply the power.
CSE-H20/H21/CIE-H10
Press the ISP button over 1 second. Or, resupply the power while pressing the button.
If the products are in ISP mode, their STS LED will keep off.
CSP-H50
Reset the power pressing the ISP button or input “pf” in command mode.EZL-300L/90
Resupply the power without wireless LAN card. The products will be operated as ISP mode for the first 2 seconds. If there are no inputs for the time, the mode will change to console mode.
Resupply the power pressing the function button. Or, press the button over 1 second.
Q: How can I upgrade the Firmware?
Each manual of products indicates details of the process.
Here is a something you should know.
Products called ezTCP/LAN, EZL-50/60 series, EZL-70, 200L, 200F, 220, 410, 400S, CSE-M32, M73, H20, H21 and H10, can download the F/W through the Ethernet port.
Products called ezTCP/WLAN, EZL-80 series, EZL-300L/S and CSW-H80, can download the F/W through the serial port.
