COMBITRONIC: N/A
DETAILED DESCRIPTION:
The ECHO command causes the SmartMotor™ to retransmit (or echo out) all serial bytes on
the transmit line that were received on the receive line of COM port 0. This retransmission
occurs when the SmartMotor reads these bytes from the buffer, regardless of whether these
bytes are command or individual data bytes. ECHO_OFF terminates the echo capability.
ECHO is required to pass serial bytes though a motor to the next motor in an RS-232 serial
daisy-chain configuration, such as when the Add-A-Motor cables are used. Also, it is often
used in single-motor applications for transmit verification.
NOTE: It is not recommended to use ECHO when the communications channel is an
RS-485 port such as an M-style motor or a D-style motor with the RS485-ISO
adapter. This mode of communication is half-duplex and is not compatible with the
ECHO command.
