EIA/TIA-449 Connections

EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions,
is a faster (up to 2 Mbps) version of EIA/TIA-232 that provides more functions and supports
transmissions over greater distances.

The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard, but it was not widely
adopted primarily because of the large installed base of DB-25 hardware and because of the larger size
of the 37-pin EIA/TIA-449 connectors, which limited the number of connections possible (fewer than
possible with the smaller, 25-pin EIA/TIA-232 connector).
