What is the difference between DB9 and DB25 RS-232 connectors?
The DB9 (9-pin) and DB25 (25-pin) are the two most common RS-232 connector types. DB9 became the standard for most modern applications because it carries all the signals needed for typical serial communication. DB25 is an older, larger format that includes additional pins for secondary channels and is rarely used in modern equipment.
