device.
The MiniRanger Plus uses simplex convention communication protocol.
Data messages are continuously transmitted at regular intervals (no poll is
required) at 4800 baud. All data is transmitted in structured messages of
ASCII characters consisting of 8 data bits, no parity, and 1 stop bit.
If Peripheral Communications (P740) is set for "formatted" messages, a
comma is inserted between each message field (except immediately
preceding the "End of Message" characters).
