It is important to complete the programming procedure before installing the receiver in its final location. The installer must have access to the receiver’s programming button and must be able to view the receiver’s LED (Light Emitting Diode) during the programming process. System The Larco Ultra-Small Transmitters and Receivers operate at 433.92 MHz (acceptable in the United States, Canada and any European Union member state) and employ code-hopping technology, reducing false activations. The receiver only operates after learning a transmitter’s signal through the simple procedure outlined on the next page. This programming procedure eliminates the need to set dip switches and involves a simple press of the programming button located on the top cover of the receiver (see drawings below for details). Installation NOTE: Complete the programming procedure on the next page before placing the receiver in its final location. 1. Mount the receiver in a location so that the antenna is not surrounded by metal. Metal attenuates RF signals causing a reduction in range and inconsistency of signal reception. Door operator motors and controls may also cause radio frequency interference. Locate the receiver away from the door control’s motor and power supply. If the receiver is mounted in a metal enclosure, drill a hole in the enclosure and thread as much of the antenna as possible through the hole. This reduces the effects the metal enclosure will have on the receiver’s reception. 2. The receiver comes equipped with a wiring harness for easy installation. Follow the color- coding scheme below the diagram at right. Diagram 2: Receiver Wiring Harness. Yellow Wire: Normally Closed Relay Output Brown Wire: Normally Closed Relay Output Common Connection Purple Wire: 12 VDC Power (NOTE: DO NOT connect 12 VAC Power) Black Wire: Ground Red Wire: 24VAC/24VDC Power Brown wire with White Stripe: Normally Open Relay Output Common Connection Orange Wire: Normally Open Relay Output Diagram 1: Receiver (left) and Transmitter (right) Dimensional Diagrams Ultra-Small Receiver Installation, Cont’d Programming Procedures NOTE: Prior to programming, make sure the receiver’s LED blinks red when power is applied. If the receiver’s LED is not blinking red, disconnect then reconnect the power. Programming transmitter(s) into the receiver’s memory: The receiver can learn up to 12 transmitters. Follow the steps below to program your receiver. Repeat steps 1-3 for each transmitter. 1. Press the receiver’s programming button for less than 2 seconds and release. The LED should change from flashing red to solid green, indicating the receiver has entered its programming mode. 2. Activate and release the transmitter once and confirm that the receiver’s LED changes to red. This indicates the receiver is learning the transmitter’s code. 3. Wait a few seconds and then activate the transmitter a second time. The receiver’s LED should now blink green several times indicating that it is ending its learning procedure. When the procedure has ended, the LED should be flashing red. Programming the receiver’s output activation time: When the receiver is activated, its outputs will stay in the minimum activation state for approximately 1.5 seconds (default). This time can be adjusted to stay in the activation state for up to 4 hours. Follow the steps below to adjust the receiver’s output activation time. 1. Press the receiver’s programming button for 4 seconds and release. The LED should be solid red. This indicates the receiver is in the activation time programming mode. 2. Activate and release the transmitter. 3. When the desired time has elapsed (up to 4 hours) activate the transmitter again. The receiver’s LED should blink green several times indicating it is ending the procedure. When the procedure has ended, the LED should be flashing red. The receiver and transmitter comply with FCC part 15/15.231-2001, Industry Canada RSS-210-2003, EN55022A-2000, EN55024-2001, EN300-220-3 V1.1.1-2000, and EN301-489-1 V1.2.1-2000. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any inerference received, including interference that may cause undesired operation. This product may be susceptible to local transmissions being generated near the transmitter’s fundamental frequency. Testing has shown some susceptibility in a frequency range of 416-440 MHz. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct interference by one or more of the following measures: (a) Reorient or relocate the receiving antenna. (b) Increase the separation between the equipment and receiver. (c) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected (d) Consult the dealer or an experienced radio/TV technician for help. The user is cautioned that any internal modifications, either replacement of or modification of any component, of the transmitter or receiver could vi…

OPERATIONAL DESCRIPTION When the transmit button is pushed the code hopping IC (“pulse modulator” in the above picture) is enabled. This chip sends out a series of data bits corresponding to its programmed and individual transmitter ID combined with the programmed company ID according to a code hopping algorithm, plus a few extra data bits that tell which of the enable pins to the code hopping chip were enabled. There are four enables on the chip but we only use one for most of our applications and two for the dual channel remote transmitter and two again on each of the two transmitter boards in the four channel remote transmitter. The bits coming out of the code hoping IC turn the saw filer on and off so that a “1” data bit turns the transmitter “on” and a “0” bit turns the transmitter “off”. A transistor in the output amplifies the signal. A capacitor and resistor (not shown) take the original button press and extend the enable time to several seconds (around 25s) so the transmitter can repeat the message many times making it more likely that the receiver will get the message.
