<strong>10</strong>-CHANNEL ROLLING CODE <strong>UHF</strong> REMOTE CONTROL (Order <strong>Code</strong> <strong>3181</strong>)<br />
This kit is based on a kit published in the electronics magazine Silicon Chip in 7/2002.<br />
It was a <strong>Rolling</strong> <strong>Code</strong> 4-Channel <strong>UHF</strong> <strong>Remote</strong> <strong>Control</strong>. We suggest you download the article from<br />
http://www.quasarelectronics.com/pdf.htm (file 3180.pdf)<br />
since it fully discusses what <strong>Rolling</strong> <strong>Code</strong> is and explains the operation of the Kit which we have<br />
not repeated here. In that kit each of the 4 buttons controlled a relay and whether the action was<br />
momentary or toggle was jumper selectable. However, if you refer to the technical details about the<br />
Automicro devices which can be got from<br />
http://www.quasarelectronics.com/ds.htm (file automicro.pdf)<br />
you will see that <strong>10</strong> keypress combinations are actually supported – the 4 single buttons and 6 twokeypress<br />
combinations. This kit takes uses all <strong>10</strong> keypress combinations to operate <strong>10</strong> relays. Each<br />
relay output is rated to switch resistive loads of up to 1<strong>10</strong>Vac/24Vdc @ 1 Amp maximum. You can view the Data<br />
Sheet for the relays at http://www.quasarelectronics.com/ds/az_relay.pdf<br />
A preprogrammed PIC16F628-04/P is used to do all the keypress decoding and relay activation.<br />

The kit starts in momentary mode for all relays – that is, the relay only operates when the button is<br />
depressed. However, if you keep the button or keypress combination depressed for more than two<br />
seconds you go to toggle mode for that particular relay. The MODE LED will come on after the 2<br />
seconds to indicate that the mode has changed.<br />
Up to 15 Transmitter units can be learnt by one Rx unit. Press button 1 (the button all by itself)<br />
while simultaneously pressing the LEARN tact switch on the main board. You only have to do this<br />
briefly for under a second. But note it takes about 15 seconds for the two units to internally connect<br />
and recognize each other. (During this 15 seconds it seems that one and only one keypress of the Tx<br />
unit will be recognised. Just disregard this. Wait the full 15 seconds until the two units have<br />
connected. Do not press the LEARN button again. Just wait 15 seconds.)<br />
Tx units attached to any Rx unit can be unattached by pressing the LEARN button continuously for<br />
8 seconds. The IND LED, L11, is on during these 8 seconds. As soon as this LED goes off then you<br />
know that all Tx units previously recognized by the Rx unit have now been unattached from the Rx<br />
unit.<br />
If you want more details about the Microchip technology behind these Tx & Rx’s then go to<br />
http://www.quasarelectronics.com/ds.htm (files AN662.PDF and AN665.PDF)<br />
We sell Tx units and Rx units separately as 30A16Tx and 30A16Rx.<br />
Assembly. See Parts List below. We have supplied 30 pins for the Common, Normally Open<br />
(NO), and Normally Closed (NC) pads from the <strong>10</strong> relays. However, you may add your own<br />
terminal blocks here if you wish. We have designed for both. Follow the overlay for component<br />
placement. Solder the lowest height components first – the resistors and diodes. Make sure to get<br />
the diodes and electrolytic capacitors around the right way. We have supplied green LEDs for L11<br />
and L12.<br />

GENERAL RELAY INFORMATION<br />
Warning! Risk of Electric Shock!<br />
This information concerns kits and modules with relay outputs. TO USE THE RELAY OUTPUTS<br />
SAFELY YOU MUST OBSERVE THE MAXIMUM VOLTAGE AND CURRENT LIMITS QUOTED<br />
IN THE PRODUCT DOCUMENTATION (this is because the board design may not be rated to<br />
switch the maximum voltage and current limits printed on the relay itself or specified in the relay<br />
manufacturer’s data sheet).<br />
<strong>Control</strong>ling mains equipment with relay outputs must be treated with extreme caution. Electric<br />
shocks can cause severe and permanent injury or even death. Construction, installation, testing and commissioning<br />
should only be attempted by suitably qualified persons, or under the supervision of a suitably qualified person. These<br />
products are not suitable for children. Before connecting mains powered equipment to the relay outputs please check<br />
with the relevant authorities in order to ensure compliance with all current safety regulations.<br />
Many areas of the assembly may operate at mains voltage. A suitable isolating enclosure must be used. Exposed screw<br />
terminal blocks on some products must be insulated to prevent contact with exposed metallic parts at mains potential.<br />
Connected equipment should be suitably fused.<br />
You will find relay outputs on many of the kits and modules that we sell. A relay is an electrically<br />
operated on/off switch. The voltage and current limits specified in the product documentation<br />
generally relate to resistive or light inductive loads.<br />
<strong>Relay</strong> Terminals<br />
Most boards have SPDT (Single Pole Double Throw) style relays. These have three outputs:<br />
C = Common<br />
NO = Normally-Open contacts connect the circuit when the relay is activated; the<br />
circuit is disconnected when the relay is inactive. It is also called a Form A<br />
contact or "make" contact.<br />
NC = Normally-Closed contacts disconnect the circuit when the relay is activated;<br />
the circuit is connected when the relay is inactive. It is also called a Form B<br />
contact or "break" contact.<br />
Connecting the Device you want to <strong>Control</strong><br />
You must provide an external power source to the device you want to control. No voltage is present at<br />
the relay terminals (remember it is just a switch). The relay is normally connected in series with the<br />
positive (+) power wire of the device you want to control.<br />
In this case, the positive wire from the power source should be connected to Common. Then either<br />
the NO or NC terminal (as appropriate for your purpose) is connected to the positive (+) wire going to<br />
the device you want to control. The negative (-) wire does not connect to the relay at all. It goes<br />
directly from the power source negative output to the device negative (-) terminal.<br />
Typical SPDT <strong>Relay</strong> Connection Diagrams<br />
Anti-Spark SPDT <strong>Relay</strong> Connection Diagram<br />
Sometimes the connected equipment can cause arcing across the relay contacts. This must be<br />
corrected by installing a resistor and capacitor (not supplied) between the two contacts of the relay as<br />
shown below. Component values are for 230Vac mains.<br />
We accept no responsibility for injury, loss, or damage of any kind caused by or resulting from improper product assembly, testing, commissioning or use.
