chassis to the box by inserting the two supplied #6-32
x 1/4"
screws into its top and bottom center holes.
6 Using the three supplied wire nuts, attach the two black
transformer wires to the two main power lines (typically
black and white). Then attach the green grounding wire
to the third (safety ground)
wire of the power
line
(typically
green, also). Press these wires inside the
chassis so there will be ample room to insert the VFD
assembly.
8 Orient the three-pin
connector
so that the larger ends
of the holes (containing
the insulation-piercing
sockets)
are to the left and the exposed side is facing upward.
8 Insert the wires from the LCD driver into the insulation-
piercing sockets of the connector. Route the wires into
the connector at a right angle from the top; do not strip
insulation from the ends of the wires. An insertion tool,
such as Rauland' s
G2522,
would be helpful. Refer to the
appropriate
wiring table on the right.
@I Orient the VFD assembly horizontally,
with the seven-
pin terminal
("J5")
to the right. Push the seven-wire
connector onto this terminal with the red wire coming
out from the bottom. Now push the three-wire connec-
tor onto the three-pin terminal ("J9") located on the left
side of the board; the shield should be at the bottom.
The pin designations
are marked
on
the printed circuit
board and are referred to on the attached IL0364.
8 Making sure that all the wires are routed inside the
electrical box, carefully insert the VFD assembly into the
chassis
8 Using the #6-32 x 1" black flathead Phillips screws,
carefully install the front panel.

the DIP Switch
Overview
The eight-position
DIP
switch on the back of the display
configures the unit for different systems.
Important:
The
TC4222
checks the DIP-switch settings
only when it is powered
up. Unless its power has been
cycled off and back on, it will ignore changes made while
it is running.
