General Information
Description Planning
The TC4222 Vacuum Fluorescent Display (“VFD”) may
be used as an alternative to the LCD displays of the
Telecenter Systems. The TC4222is larger and brighter than
an LCD module and, being wall-mounted, can serve as the
display for several nearby administrative phones. It is
compatibIe with Telecenter@ IV, Telecenter V, Telecenter
TCS, Telecenter System 21, and Telecenter 1100 systems.
Attachments
IL0364 (Installation Diagram).
The TC4222connects to one of the two LCD drivers on
the Main Input/Output (MIO) module. Each LCD driver
accommodates up to three displays (LCD or VFD, in any
combination) and a total cable length of 1,000 feet. Refer
to the System Wiring Diagram (KMO674) in the main
Telecenter IV manual (KI-1435) as well as to the attached
drawings.

primary display-driver can accommodate up to 16 displays
(LCD or VFD, in any combination), and a total cable length
of 2,000 feet of 22-AWG wire. Refer to the System Wiring
Diagram (KM1035) in the main Telecenter V manual (KI-
1687) as well as to the attached drawings.

chassis to the box by inserting the two supplied #6-32
x1/4"
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.
@IOrient 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.

Setting 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.
Telecenter V and Telecenter System 21
For
TCV
or

operation, push slide switch 8 Off
and 5 On. (This selects the Telecenter V or Telecenter
System 21 mode of operation.)

ff = TCV & TC2100
n = TCIV,TC TCS,
Because the Telecenter V and Telecenter System 21 uses
a single-display drive, all displays receive the same mes-
sages. However, only the unit with the corresponding
address will display an individual message.

Troubleshooting
Diagnostic Mode
-w To select the diagnostic mode, set all slide switches On.
This mode works with
TCV
and
TC2100
(tone) or
TCIV
and
ChronoCom (pulse) applications.
The display shows all the characters received from
either the pulse or the tone inputs as hexadecimal charac-
ters. When the screen is full, the display will pause before
showing the next screen of hexadecimal characters. The
unit can buffer up to 30 undisplayed characters.
Here is a typical hex message on a Telecenter V system:
01,8l,lB,0l,[Text]
(81 = address 1;
lB, 01 =
SetCursor 1)
The
TCV
and TC2100 systems use a 40-kHz carrier to
transmit asynchronous ASCII serial data
Test Procedures
, Use a voltmeter to check the “Display” terminals (“RED”
and
“DLK”
terminals): during normal operation, you should
get a reading of 10 to 12 VDC.
Within five seconds of being turned on, the display
should show an initial message, such as “Vervvv DD,”
where “Vvv” represents the software version number, and
“DD” represents the DIP-switch setting.
Note: The 5th and 6th bits of
“DD”
are
“0” regardless of
- the DIP-switch settings.
