RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Need Help with Bim2 Transceiver - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

Post subject: Need Help with Bim2 Transceiver

I am using a Radiometrix
Transceiver to control an Alarm System. Can any1 help me with the use
of the Bim2.
I know that I have to send a preamble, followed
by a start bit, then the data (Manchester Encoded), then a stop bit
and CRC checksum.
I am not sure how the start and stop bits work
(i.e. does the transceiver use them or does the Microcontroller that
I am using have to understand them?).
Does all the data packet
have to be Manchester Encoded or just the valid data?
has any info or advice they could off I would be greatful.
