Circuit Design, Inc. List of Products and Services

The RT/RR series is a specific low-power radio device operating in the 315MHz band that complies with ARIB STD-T93 and has obtained the technical conformity mark. It offers longer communication distances and more stable communication compared to weak radio remote control devices. Additionally, it does not have the directionality of infrared remote controls, allowing you to use it without worrying about the orientation or location of the transmitter. You can choose between two types of remote controls: 3-button and 4-button. There is also a wireless module type available (RTM-1B, RRM-1A). When a button is pressed, it performs a one-shot transmission, making it suitable for applications such as switching lights or displays ON/OFF. Wireless remote controls: RT-3B (3-button), RT-4B (4-button) Control unit (receiver): RR-1A Wireless module type: RTM-1B (transmitter), RRM-1A (receiver)

The RT-3B is a specific low-power radio device operating in the 315MHz band, compliant with "ARIB STD-T93," and comes with a technical compliance mark. Compared to weak radio remote control devices, it allows for longer and more stable communication distances. Additionally, it does not have the directionality of infrared remote controls, enabling use without worrying about the orientation or location of the transmitter. It can be used in combination with the RR-1A and RRM-1A. 【Features】 ■ One-shot transmission with 3 buttons ■ Communication distance of approximately 50 meters in line of sight ■ Operation confirmation with LED and buzzer ■ Lightweight and slim design

The RT-4B is a specific low-power radio device that operates in the 315MHz band and complies with "ARIB STD-T93," featuring a technical compliance mark. Compared to weak radio remote control devices, it allows for longer and more stable communication distances. Additionally, it does not have the directional limitations of infrared remote controls, enabling use without concern for the orientation or location of the transmitter. It can be used in combination with the RR-1A or RRM-1A. 【Features】 ■ One-shot transmission with 4 buttons ■ Communication distance of approximately 50 meters in line of sight ■ Operation confirmation with LED and buzzer ■ Lightweight and slim design

The remote control receiver RR-1A receives and outputs contact information from the transmitter. There are four contact outputs, and it supports three output modes. It also supports serial data output. Up to 32 transmitter IDs can be registered. It can be used in combination with RT-3B / RT-4B / RTM-1B. 【Features】 ■ Capable of 4 contact outputs ■ Supports three output modes: one-shot, toggle, switching ■ Up to 32 transmitter IDs can be registered ■ Communication distance is approximately 50 meters in line of sight.

The RTM-1B is a radio transmission module for specific low-power wireless communication that conforms to the standard "ARIB STD-T93." It can wirelessly transmit input signals from 4 contacts. Since it has the Technical Compliance Mark, it can be incorporated into devices without the need for a license application by the customer. Compared to conventional weak wireless and infrared remote controls, it offers a longer communication distance and stable communication without worrying about location or orientation. It can be used in combination with the RR-1A or RRM-1A. 【Features】 ■ Construction design certification obtained ■ One-shot transmission for 4 contacts ■ Communication distance of approximately 50 meters in line of sight ■ Lightweight and compact

The 4-point wireless receiving module RRM-1A receives and outputs contact information from transmitters (RT-3B / RT-4B / RTM-1B). It has 4 contact outputs and supports 3 output modes. It also supports serial data output. Up to 32 transmitter IDs can be registered. The transmitters that can be used are RT-3B, RT-4B, and RTM-1A. 【Features】 ■ 4-point output ■ Up to 32 transmitter IDs can be registered ■ Communication distance is approximately 50 meters in line of sight
