Hi all,
I need to maintain communications with 80 devices overRS-232 serial (115k).
Each device streams an approximately 120 byte packet every 100ms.
also the host, can send packets, and expect a response at any time. The
packets are hex encoded with out of band start and stop characters.
I am contemplating using 10 ts-7550s (with appropriate level shifters) to
control the devices, and forward the data over ethernet. The intent would be
to crack the serial packets (which include 2 crc32 checks) down to their 60byte
binary size, buffer 10 or so serial packets per channel, (600bytes per
ethernet packet) and send them on up to a host for logging and display.
My data rate calculations show very modest ethernet usage (8 x 600 bytes/s).
On the surface the ts-7550 looks like a nice fit for this. Anyone have any
experience with the XUARTs , or better suggestions? Probably no more than 3
<80 channel systems> will be built.
Best Regards Mike
