INDUSTRIAL ETHERNET MOD AND NET LEDS

LED behavior is specified by each protocol. The functionality of

the MOD and NET LEDs, shown as LED1 and LED2 in Table 16

vary depending on the industrial Ethernet protocol selected. This

functionality is described in the RPG2 Hardware Design Integration

Guide.

PROGRAMMING

The secure methods of updating the module are through the follow-

ing:

►

The industrial Ethernet ports via a webserver interface described

in the RPG2 Web Server User Guide.

►

A JTAG connection, which is described further in the RPG2

Programming Guide.

If the ADIN2299 schematic is implemented directly on the customer

board as a reference design instead of purchasing a module, the

only option for programming is through a JTAG connection using

the Segger toolchain. Note that a serial wire debug connection

is not supported. See the RPG2 Programming Guide for more

information.
