Serial Interface Cable

At the network end, the connector is different for each type of cable, as described in the following list:

■V.24 (EIA/TIA-232) DTE cable — DB-25 (male) adapter

■V.24 (EIA/TIA-232) DCE cable — DB-25 (female) adapter

■V.35 DTE cable — 34-pin (male) adapter

■V.35 DCE cable — 34-pin (female) adapter
