Serial Port
Model 3986 units with serial port enable V.35 or X.21 interface connection to local DCE and DTE devices.
The V.35 interface is presented either on a M/34, or DB-25 female connectors. The X.21 interface is presented
on a female DB-15 connector. Figure 5 shows the different connectors offered for the serial port.

Connecting the serial port
The serial port in the 3086 is simple to install. The V.35 interface is wired as a DCE, the X.21 interface can be
configured as a DCE (factory default), or as a DTE via internal configuration jumper.
Connecting the 3086 serial port to a DTE
The serial port on the Model 3086 is configured as a DCE so it connects directly to a DTE using a standard
straight through cable. The cable should present either a male M/34 or DB-25 connector on one end, for V.35
interfaces, or a male DB-15 for X.21 interface connection. The other end should be terminated with the
appropriate connector ( check your DTE equipment manual for pinout, gender, and DTE/DCE port configu-
ration).
