EIA-530 Connections
EIA-530, which supports balanced transmission, provides the increased functionality, speed, and
distance of EIA/TIA-449 on the smaller DB-25 connector used for EIA/TIA-232, instead of the 37-pin
connectors used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of
EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps,
EIA-530 is used successfully at 4 Mbps or faster over short distances.
The EIA/TIA-530 adapter cable is available in DTE mode only. The network end of the
EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections.
Figure 2-5 shows the DB-25 connector at the network end of the adapter cable.
