115,200 Baud Serial Port Data Rate - iButtonLink LINK 12 User Manual

115,200 Baud Serial Port Data Rate

Command " : " (colon)
Command Compatible With:
LinkHub-S | LinkOEM
Before utilizing this command, the host terminal will be required to switch to 115,200 baud
TM
before it can communicate with the LINK device further.
TM
This command switches the LINK device to the 115,200 baud serial port data rate. When a
break condition is detected, the device will reset to the 9,600 baud data rate. Sending the " ^ "
command followed by more 9,600 baud data will often cause the device to reset and the speed to
return to 9,600 baud.
N : The 1-Wire® bus with relaxed timing for long lines can only process bits at a rate of
OTE
TM
about 14,000 bits per second (bps). If a user sends characters to the LINK faster than the 1-
Wire® protocol rate, the device will drop characters and cause errors. Streaming bytes using the
" b " command will fail if the baud rate is set to more than 19,200 bps because the host will
overrun the 1-Wire® bus. When the baud rate is set to a value greater than 19,200 bps, the host
commands must be passed to assure than the 1-Wire® bus is not overrun.
