Desktop Hookup
Getting Started
This chapter describes how to connect and powerup the DL20 for desktop
message programming.
To set up the DL20 for desktop use, you need:
Three-prong AC line cord
Keyboard ( Catalog No. 2706-NK1 or -NK2)
The keyboard connects to the DL20 via a cable attached to the keyboard
Cables are available to connect the DL20 with Allen-Bradley Industrial
Terminals T1 through T4, most DTE type dumb terminals, DEC VT52,
VT100, VT101 Terminals and IBM compatible computers. See Table 2.A,
Accessories.
Connect Power Cord
Attach the power cord. One end of the cord has a three-prong plug, the other
end has three colored spade connectors: white, green, and black.
Connect the black lead to terminal 26, the 120V AC HOT terminal on
the rear of the DL20
Connect the white lead to terminal 27, the NEU terminal
Connect the green lead to terminal 28, the E. GND terminal.
ATTENTION: The ground wire is ESSENTIAL for proper
operation. Without this lead, the chassis does not protect the in-
!
ternal circuitry from static electricity or electrical noise; nor will
it protect you from shock if there is an electrical short to the case.
