The TC4221 can be used as a direct replacement for a TC4220, but it offers a number of new features as well, notably its capab

3、ility of being individually addressed in a Telecenter V and Telecenter System 21 system. The following parts should come with the display: 4 1” x 2 1/2” double-sided foam strip, for fastening the display to the telephone. 4 Nine-inch, six-conductor modular phone cord. Number of Displays The display

4、matches the Rauland TC4204 Administrative Telephone. It can be used with many other DTMF (dual-fre- quency, multi-tone) desk phones, the only limitation being aesthetics. Figure 1 shows a typical placement. Telecenter V and Telecenter System 21 systems have a single display driver that can support u

5、p to 2,000 feet of cabling and 16 displays. Each display may be assigned its own address with its DIP switch (see “Setting the DIP Switch,” the final section of this manual). Telecenter 1100, Telecenter IV, and Telecenter TCS sys- tems can support up to 1,000 feet of cabling and three displays per d

11、lation Right Way Terminal side Mechanical Note: For Telecenter V and Telecenter System 21 systems, set each display s DIP switch before attaching the display to a telephone. See “Setting the DIP Switch,” on the following page. Before attaching the assembly to the telephone, install the nine-inch mod

12、ular phone cord and anything else that might be covered by the assembly. Use the double-sided foam to secure the assembly to the phone. Do not cover anything with the foam that you might need to remove in the future (e.g., the cord that runs from the display unit to the phone. Caution: The foam bond

13、s tightly to any hard surface it touches. To assure a smooth installation, stick the foam to the display unit first. Before touching the foam to the tele- phone, make sure the display is properly aligned. Wiring This section tells the basic connections. For details, con- sult the system manuals list

14、ed above and the manufacturer s manual for any other component (e.g., a special-features telephone). Observe Proper Polarity! This is especially important for the display, which could suffer damage from several minutes of exposure to reverse polarity. To avoid damage, promptly disconnect the display

15、 if it does not show the sign-on message a few seconds after you turn on the system. Check all wiring connections and the polarity of the modular connectors on the desk cord and the cord between the display and the phone. The positive LCD output should be connected to the “BK” (“Black”) terminal, an

16、d the negative output to the “YL” (“Yellow”) terminal of the telephone terminal block. See Figure 2 and the wiring table. Wrong Way Terminal side Tab side -d Figure 2.

See the main wiring diagram (KM1035) in the TCV manuals. Telecenter System 21 displays can also be wired direct to the MSM port punch b

20、locks. See the appropriate diagram in the Telecenter System 21 Installation Drawings manual, KI-1767. Adjusting the Display The contrast adjustment for the display can be accessed through the lower left hole in the back of the unit (as viewed from the rear). Use a small, flat-blade screwdriver for t

21、he adjustment. Troubleshooting Use a voltmeter to check the “Display” terminals (black and yellow wires): 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 “VW” represents

22、the software version number, and “DD” represents the DIP-switch setting. (Note that, the first time, you may need to adjust the contrast to see the message.) Note: You can check the display apart from the system, by using a separate power source (12 VDC, 5-10 mA). Setting the DIP Switch Overview The

23、 eight-position DIP switch on the back of the display configures the unit for different systems.
