Ring a Telephone Using RC4 AC-Wave Synthesis (W-DIMm3)

I. Items needed to make a W-DIMm3 ring a Bell telephone

A. W-DIMm3

B. A small tool like a small bent paper clip

C. Screw driver

D. Bell telephone

E. Step up center tap transformer

1. Here is a list of suitable transformers available from Digikey, an online electronic parts supplier.  (If Digikey changes their system and breaks this link, please let us know at support@rc4wireless.com.)

2. This is a transformer that is used in simple power supplies that deliver + and – voltages

a. By injecting low voltage into the secondary (low voltage) side of the transformer, high voltage will come out of the primary (high voltage) side

F. The W-DIMm3 will produce alternating current that will be stepped up to ring the telephone

G. Set up is shown in this diagram: view image, or download PDF.

II. Configuring the W-DIMm3 dimmer to ring a telephone

A. In the example, the unit starts in default mode

B. Special dimmer curves are hidden at a low end of the Enhanced OneTouch process

C. Enhanced OneTouch uses a tight matrix of all available dimmer curves starting at a DMX channel level of 20 (not 20%, the actual level of 20 out of 255)

1. A DMX level of 30 selects the AC wave generator

(See the complete outline of Enhanced OneTouch curves and associated channel levels.)

D. In this example, the telephone will ring on DMX channel 25 using RC4 Enhanced OneTouch

E. On the console, set DMX channel 25 at a DMX level of 30 (not 30%) for the AC wave curve

F. This should be the only channel up on the console

G. Using a small tool like a bent paper clip, tap and release the Set A Button on the W-DIMm3

H. A pair of LEDs on the W-DIMm3 will being dimly flickering

1. As the level is increased on the DMX channel, the flickering LEDs on the W-DIMm3 will become brighter

III. Wiring in the transformer

A. Bring the DMX channel down to zero

B. On RC4 dimmers, the common on the output is positive

1. The center tap will go to the positive side

C. Each of the outside wires go to the negative sides of the two ganged dimmers

D. On the RC4 dimmers, this is typically three wires in a row, with the common positive in the center

IV. Wiring the phone

A. An RJ-11 plug can be used on the phone (standard telephone cord)

B. An RJ-11 jack can be used at the transformer

C. In this example, non-standard connectors are being used on the transformer and phone

D. Connect the telephone plug to the transformer jack

E. Bring up channel 25

F. The phone will ring

1. The cadence of the ring is controlled via the DMX channel

2. Typically the level will be brought to full for a strong and even ring

G. In a typically wired stock telephone, the bell will stop ringing when the handset is picked up

1. This is part of the internal mechanics of the phone itself
