Null Modem Cable

Null modem cables are frequently used (crossover) standard cables for connecting instruments to the PC. However, the term "null modem cable" is not defined clearly and precisely, and thus it is used for a number of different cables.

 Tip:

Do not confuse crossover null modem cables with non-crossover Modem Cables (1:1 RS cables)!

For details about pin assignment and connection of null modem cables, refer to Null Modem Cable in the Administrator Help section.
