Encoder Enables Robust Serial Protocol

Encoder Facilitates Robust Serial Protocol

The new DS Series Encoder/Decoder IC from Linx makes it simple to add a robust serial protocol with the ease of DIP switch addressing. The DS lets users set up to 1,022 unique addresses for reliable communication between devices, similar to older Holtek® products, but with a stable serial protocol. Testing shows greater than 2X range increase in reliable, stable communication over the Holtek® protocol, with the DS Series device in serial protocol mode.

The market exit by Holtek® from the DIP switch device market has left many customers in a lurch – Linx is here to help you out. In addition to its robust serial protocol the DS Encoder/Decoder IC includes support for the older Holtek® protocol, providing a migration path for the many applications using Holtek® devices, such as the HT640 and HT658. Compatibility with other Holtek® devices is possible, contact Linx for further information.

To aid rapid development, the DS Series Encoder/Decoder is available as part of a basic evaluation system. The system comes with two evaluation boards for benchmarking and prototyping, one with a Linx LR Transmitter and DS Encoder and another with a Linx LR Receiver and DS Decoder.

2 years ago:  I see this is similar to the range of remote receiver tx devices that were offered by maplin electronics

One of the major point I notice is that there is no rolling code This makes this type of serial transmission device easily crack able and would not be very useful in remote control Rf environments where devices such as this would be used in say example RC toys , planes , boats, security aware applications

You would also be limited in the number of distinct addresses that you could use which would give rise to possibility of the same RC device operating more than one unit at a time


knowing that you would be aware of this although I also note it ustilises CRC Why are we still developing Integrated circuits of this nature when we are supposedly looking at attempting to create far more secure environments ?

Whilst I appreciate this may be a cheap solution for many markets A tiny bit of extra code goes a long way wouldn’t you rather pay an £1 extra knowing that this would meet expectations long term rather than opt for a cheaper solution which may present difficulties later on ?

I am refering to the number of RC rejected toys because of this problem
