Introducing.......
the TeleSwitch
controller system

The newest TeleSwitch, introduced in May of 2006 is primarily an advancement on the original TeleSwitch.  We thought you might like to review the information on the original model since it will help you better understand the capabilities and applications for this incredible product.

Not too long ago, we were contacted by an electrical contractor who wanted some kind of wireless device to remotely turn on a device.  We had a radio transceiver developed for the OEM market.  We were already using these transceivers is some of our custom products developed for courtroom security and law enforcement.  We also had a DTMF controller that was developed primarily for wireless gate activation.  It was pretty much a matter of hooking these two items together, programming them to do what we wanted to do and connecting them to each other.  Lastly, we needed a personal 2-way radio capable of sending DTMF control tones and the TeleSwitch solution was available and for sale for those who needed this technology.

As it turns out, there are a LOT of applications for the TeleSwitch system.  The manager of a private golf club told us we would like a low cost alternative to the wireless pump control systems used by larger golf courses.  We have long supplied the radios used with such systems but we had never thought of addressing the total solution.  As it turns out, this user only needed the ability to remotely control three pumps.  We were already using wireless voice alarm annunciation products for monitoring lift station pumps, water tank overflow valves and a variety of similar applications.  With the TeleSwitch, we could offer our customers the ability to control these remote pumps and valves without going to the site.  In many cases, the time saved could result in significant costs savings by reducing costly overflows and/or damaged pump motors.  In the case of the golf club, simplifying  irrigation procedures gave him more time to do other important things - like taking care of his members!

The TeleSwitch system is simple, affordable, and effective.  Here's how it works.......

General:

The Ritron TeleSwitch Controller essentially consists of six components – the DTX Series FM transceiver module, shown at the left,  the GGT-1/1F DTMF decoder, shown later, and a serial data connector cable as shown above.  The system operates from a 12 volt power source rated at 3 amps.  A power supply is provided that connects to the exposed red and black wires on the data connector cable.  If preferred, an external 12 VDC power source may be used as long as it is rated at 1 amp or more.  The GGT-1/1F DTMF decoder is supplied without a housing.  It can be attached to the DTX series transceiver module using supplied double stick tape or enclosed in the housing of your choice (not supplied).  An external antenna with magnetic mount and a PC programming kit for the DTX FM transceiver is also included.

Theory of Operation:

The TeleSwitch Controller is normally used in association with a personal 2-way radio transceiver capable of transmitting a DTMF code 123 on the frequency of 151.880 utilizing 12.5 kHz channel spacing.  The personal 2-way radio normally used is the Ritron SLX series, shown at the left, pre-programmed on the aforementioned frequency on the first channel selection (CH-1).  The code is sent by momentarily pressing and releasing the P1 button on the front of the radio.  Pressing this button will automatically transmit the DTMF 123 code.  Note:  Some models may use a 125 code.  If applicable, you can use the P2 button to send a 125 code.

The code is received by the DTX FM transceiver module and decoded by the GGT-1/1F DTMF decoder that activates a set of relay contacts (See diagram on the following page).  These contacts are connected to an external device with a pair of wires (not supplied) between the normally open (N/O) relay contacts on the GGT-1/1F DTMF decoder.  Each time the button is depressed, the transmitted signal will switch the relay contacts from normally open to normally closed.  The GGT-1/1F is generally set for momentary contact and then return to a normally open condition.  If latching capability is required, please give us a call at 1.800.489.2611.

Once the DTX FM transceiver module has been connected to the GGT-1/1F board, your next step would be to connect the antenna with magnet mount base (supplied), then connect  the wires to the GGT-1/1F from the associated device relay, and lastly connect 12 volt power using either the AC adapter provided or your own 12 volt DC power source.

 


Operating Procedure

With the aforementioned connections, you would be ready for a test of the system.  To perform a test or activation, you simply turn on the SLX radio (radio should be charged overnight before using).  Make sure the radio is on Channel 1 (CH 1).  Press and release the P1 button to send the DTMF control code.  The relay should activate as desired to control your external device.

In the event you choose to use a different frequency other than 158.880 MHz, we have preprogrammed the frequencies of 151.820, 151.940, 154.570, and 154.600 have been programmed on channels 2 – 5 with a privacy tone of 186.2 Hz with 12.5 channel spacing.  Using one of these secondary frequencies will require reprogramming of the GGT-1/1F decoder using supplied programming kit.  If desired, the TeleSwitch controller system can be programmed on any VHF or UHF frequency of your choice.
