OEM Compact Handheld Transmitter Data Guide Description R 0.2" The CMD-HHCP-***-xxx-MD Compact Handheld transmitter is ideal for general 2.00" remote control and command applications. 2.81" As a part of our DS Series encoder-based 1.35" OEM family, it has been pre-certified for FCC Part 15, Industry Canada, and European CE (433MHz only) compliance, reducing development costs and time to 1.62" 0.20" 0.60" market. Available in 315, 418 (standard) or Figure 1: Package Dimensions 433.
Theory of Operation Ordering Information The CMD-HHCP-***-MD Compact Handheld transmitter combines the LR Series transmitter with an internal Splatch Series antenna and an on-board DS Series encoder IC to form a simple, yet highly reliable, RF remote control transmitter. The LR transmitter is a low-cost, high-performance, synthesized ASK / OOK transmitter.
Protocols Setting the Transmitter Address The DS Series encoder inside the Compact Handheld transmitter supports two protocols. The first protocol is based on the Holtek HT640 encoder and is completely backwards compatible with older generation transmitters and systems based on the HT658 decoder. The second is a serial protocol that offers more noise immunity and faster response time while keeping the simple addressing.
Connection Considerations Labeling / Instruction Requirements It is important to understand that only one transmitter at a time can be activated within a reception area. While the transmitted signal consists of encoded digital data, only one carrier of any particular frequency can occupy airspace without contention at any given time.
Receivers Typical Applications There are four options for receivers within the Linx product line. The first option is to use one of the OEM Function Modules, such as the Relay Module. These items are also pre-certified and can be immediately included in a product. The outstanding sensitivity of the LR Series receiver offers the best range when used with the Handheld transmitter. When using the LR Series receiver, the DS Series decoder chip should be used to decode the received signal.
