recorder.

Connecting a Programming Terminal

The optional keyboards (Catalog No. 2706-NK1, -NK2) connect directly to
the telephone-type connector (labeled KYBD) on the rear of the DL20.
Power should not be applied to the display when connecting or disconnecting
the 2706-NK1 or -NK2 keyboards.

To connect an Allen-Bradley Industrial Terminal or most dumb DTE type
terminals to the DL20, use a Catalog No. 2706-NC1 programming cable
connected as shown in Figure 9.6.
