• Manufacturer: Delta Electronics, Inc.

The memory map in the following describes an extension to the memory map defined in SFP MSA. The enhanced
interface uses the two wire serial bus address 1010001X(A2h) to provide diagnostic information about the module’s
present operating conditions.
Note:
1) Write the password (11h, 11h, 11h, 11h) on the bytes of 123-126 of address A2h then the address of
DELTA ELECTRONICS, INC.
bytes 128-255 (User Writable) can be read and written.
