61225101L1-5B 5The local management port is a DB-9 femaleconnector and is labeled V.28. The interchangecircuits and pinouts are listed in Table 5. The localmanagement baud rate will auto-detect between 2400baud and 57600 baud.See EIA-574, Sec 2.2 and Figure 2.7, with ReceiveData, Transmit Data and Signal Ground only. Theother pins are internally connected to ensure correcthandshaking interoperability. These internalconnections shall be made via resistor traces tofacilitate with future build options.Table 6 defines the X.21 port pin connections.emaNegnahcretnI noitpircseD tuoniPDCD RTDotdetcennocyllanretnI-tceteDreirraCataDRSDdna 1DXR ataDevieceR 2DXT ataDtimsnarT 3RTD otdetcennocyllanretnI-ydaeRlanimreTataDRSDdnaDCD 4DNG dnuorGlangiS 5RSD DCDotdetcennocyllanretnI-ydaeRteSataDRTDdna 6STR STCotdetcennocyllanretnI-dneSoTydaeR 7STC STRotdetcennocyllanretnI-dneSoTraelC 8CN noitcennoCoN 9Table 5.
