TWS-434A and RWS-434 TX/RX pair

Meepo

I just received my new set from Reynolds Electronics, with info on how to hook up to an encoder/decoder pair. I'd like to use them to have one BS2 send commands to another. Can I just send data serially with SEROUT and SERIN? Is there anything special I have to do to the hardware, such as adding resistors or capacitors?

I've had great success with these little guys!· I found a really great "tutorial" at Reynolds Electronics web site...http://www.rentron.com/Stamp_RF.htm


Note that they only use a BS1 for the transmitter.

Jeez...couldn't someone have answered in less than six minutes?!?

I just ordered a pair. I'll post my results. I have some applications for uni-directional stuff. I need to break down and order the new Parallax transciever.

Meepo

I've got them talking now, and soon I'll be driving a little remote with it...but I'd like to reduce errors...is there a way to use 2 synch bytes? I'd like to send packets with 5 bytes of data, maybe some sort of simple checksum?

Chris Savage

You can use as many header bytes as you want. CRC checksum is probably the most popular form of error detection, however to be really useful both sides need to have an established protocol so when a packet is corrupted it can be resent if need be. Take care.

I just bought a pair. I haven't started working on it yet but have some questions. Does it need tuning? What is the format of the RSSI signal?
