 The '''DLV11-J asynchronous serial line interface''' card was a [[QBUS]] [[peripheral]] for the [[PDP-11]] series of computers which provided four [[asynchronous serial line]]s on a single [[DEC card form factor|dual-width]] card, the M8043.
-It provided both [[EIA RS-232 serial line interface|EIA RS-232]] or [[EIA RS-422 serial line interface|RS-422]] connectivity at speeds of 150 to 38.4K [[baud rate|baud]]; receive and transmit speeds are the same on each line, but each line could be set independently. It did not have any [[modem]] control.

It did not have any [[modem]] control. [[20mA current loop serial line interface|20mA]] operation was possible with the [[DLV11-KA 20mA Current Loop Option]].
 Line connection was via four separate 10-pin [[Berg connector]] headers on the top edge of the card, using the standard [[DEC asynchronous serial line pinout]].

 There are several options for cabling to the DLV11-J. One is to run individual cables, such as the BC20N-xx (Berg 10-pin connector, to [[EIA RS-232 serial line interface#Connectors|female DB-25S wired as a DCE]] - i.e. including a [[EIA RS-232 serial line interface|null modem]]) to each line's Berg connector. The alternative approach is that DEC produced a number of [[distribution panel]]s which can be used with the DLV11-J; all have a [[flat cable]] which splits into four sub-cables, each with a Berg 10-pin connector which plugs into one of the Berg headers on the DLV11-J.
