OEM Long-Range Handheld Transmitter Data Guide
Warning: Linx radio frequency ("RF") products may be used to control machinery or devices remotely, including machinery or devices that can cause death, bodily injuries, and/or property damage if improperly or inadvertently triggered, particularly in industrial settings or other applications implicating life-safety concerns. No Linx Technologies product is intended for use in any application without redundancies where the safety of life or property is at risk.
OEM Long-Range Handheld Transmitter Data Guide Description The Linx CMD-HHLR-***-xxx-MD Long-Range 1.375" Handheld transmitter is ideal for generalpurpose remote control and command applications that require longer transmission R 0.2" distances. As a part of our DS Series encoder-based OEM family, it has been 2.00" 2.81" pre-certified for FCC Part 15, Industry Canada 1.35" and European CE (433MHz only) compliance, reducing costs and time to market. Available in 315, 418 (standard) or 433.
Theory of Operation Ordering Information The CMD-HHLR-***-MD Long-Range Handheld transmitter combines the LR Series transmitter and LP Series antenna with an on-board DS Series encoder IC to form a simple, yet highly reliable, RF remote-control transmitter. The LR Series transmitter is a low-cost, high-performance synthesized ASK / OOK transmitter.
Protocols Setting the Transmitter Address The DS Series encoder inside the Long-Range 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.
