A "protocol" is a set of behaviors and rules
built into a device to achieve a specific purpose.
Ewave's RF Modems are available with several pre-programmed
protocols which determine how the Modem transmits your
application's data "over-the-air". Whether you
need to optimize performance, reliability or compatibility
or all of the above at once, Ewave has Modem with the
protocol support you need. And in keeping with Ewave's
goal of "drop-in" compatibility, this sophisticated
protocol processing is transparent to your application.
Available Protocol Modules
- Ewave's "FAST"
protocol is optimized for real-time, interactive applications.
It provides maximum throughput with minimum latency.
- Ewave's "PBASIC"
protocol is optimized to enable wireless debugging and
programming of the Parallax Basic Stamp microcontrollers,
which significantly speeds your edit-compile-debug cycle
for applications in mobile, robotics, inaccessible locations
or hazardous environments.
- The "Checksum"
protocol augments the normal error detecting features
with a 16-bit CRC (cyclic redundancy check) to reject
data packets corrupted by noise at a slight cost in
- Ewave's "Break"
protocol is designed for applications using RS232 handshaking
signals or serial "break" conditions. The
RF Modem passes through the state of RTS/CTS and detects
and emulates "break" conditions so that you
can avoiding changing your application or device.
- Originally developed for the
harsh robotics competition environment, the "RM2000"
protocol is optimized for real-time, ultra-low-overhead
telemetry and control. Unlike the other protocols, it
uses fixed-length data packets "over-the-air"
and includes an elegant mechanism to recover from synchronization
errors within a single packet's time.
