Programming Terminals
The programming cable hooks up similarly. One end of your cable has a D
type connector which mates to a D connector on your terminal. Connect this
end of the cable to the serial communication port on your computer. On the
Allen-Bradley terminals, use the Port B connector.
The other end of your cable has three numbered spade connectors which
attach to the similarly numbered terminals on the back of the DL20.
Keyboard
The telephone type connector on the keyboard cable plugs into the KY BD
connector on the back of the DL20. Only use the KY BD connector with
programming keyboards (Catalog No. 2706-NK1 or -NK2).
ATTENTION: Do not connect or disconnect the keyboards
when power is applied to the DL20. Damage to the DL20 could

result. Do not connect or disconnect a peripheral device to the
serial RS-232/RS-422 ports of the DL20 when the display is in
run mode. Erroneous data could be entered.
