Serial Configuration Mode
This is a mode for setting environmental parameters through RS232 port. If you can’t use
the Ethernet, this mode is only way to configure the values. Once entering this mode, use
the [Read] button on the [Serial] tab of ezManager. (Figure 3-4)
Refer to the [Serial Management Protocol] document on our website for details.

ISP Mode
There are two different ways to enter ISP mode. One is to apply LOW signal to ISP pin
for over 1 second, the other is to apply power on CSE-M53N while ISP pin is connected to
GND. Entering the ISP mode is used for two purposes in the below chapters(4.6.1/4.6.2).

CSE-M53N offers restriction methods for security like filtering password or MAC and IP
