9 bit serial protocol

Select your search: Site Products. December 9, Sealevel. Definition of 9-bit framing 9-bit data framing is a simple, yet effective, method of allowing many embedded devices on a multidrop network to maximize processing time. Typical bit data framing When using typical bit data framing, a communication layer protocol must be used to identify the target of the message. How 9-bit framing saves time Many embedded multidrop devices can use 9-bit data framing to significantly reduce wasted time checking network messages.

I have found the way to set the UART for 9 bit serial but I have not found how to read and write the 9th bit. Is there any documentation on how to read and write the 9th bit of the data byte? Thanks for any assistance. Have you tried the datasheet for your device? Maybe all it takes is a simple ass'y command or two. Thanks for pointing out the obvious. If you needed to transmit binary instead, you would still transmit hex 0x88 but set the parity to Mark.

Note that when shown in binary the least significant bit is the leftmost bit, as the least significant bit is sent first in serial transmission. For example, let's say you set your parity as Space. If you read in a byte and you get a parity error, you know that the 9th bit is Mark and can append the appropriate bit.

LabVIEW 6. You can change this behavior by modifying the visaconf. Note that if your instrument only needs to receive the 9th data bit for addressing purposes, but never sends data on the 9th bit, you should only need to set the parity once to what your instrument is expecting. How to modify the visaconf. For users of Windows Vista or later, the visaconf. What to order? Of course also in the 64 bit x64 version of SuperCom. Home Back. It Simply Works! Updated on:
