Take the risk out of equipment purchases with the Double Diamond™ Warranty from Black Box Network Services.
The Double Diamond Warranty is our warranty that protects
your Black Box® brand products* from accidental damage, including drops, water,
and power surges.
The USB to RS422/485/530 Converter, DB25, 1-Port comes with a standard Lifetime Double Diamond™ Warranty (Standard) already included.
During the warranty period, Black Box Network Services will repair or replace your damaged equipment
