The local management port is a DB-9 female connector and is labeled V.28. The interchange circuits and pinouts are listed in Table 5. The local management baud rate will auto-detect between 2400 baud and 57600 baud.

See EIA-574, Sec 2.2 and Figure 2.7, with Receive Data, Transmit Data and Signal Ground only. The other pins are internally connected to ensure correct handshaking interoperability. These internal connections shall be made via resistor traces to facilitate with future build options.

Table 6 defines the X.21 port pin connections.
