ISP Switch
There is an ISP switch located on the back of the product. It is used to turn CIE-H14A
into the serial configuration mode or ISP mode. If you press it between 20 milliseconds and
1 second, CIE-H14A will go into the serial configuration mode that you can configure the
environment parameters through the RS232 port. If you press it over 1 second or supply
power while pressing it, CIE-H14A will go into the ISP mode. In this mode, you can upload
the firmware file or HTML files.

In the ISP and serial configuration mode, you can reset a password or cancel access
restriction. Use these modes when you are faced with the problems.
