Enable – Disable Input ECO Characters
By default, the unit transmits the ECO of all characters received from
the host.
If required, It is possible to disable this feature.
See the command "Enable, Disable Receiving Input ECO" to do this.
The ECO of input characters may be used to understand that the
physical communication between the unit and host is good so,
disabling the ECO this feature is lost.
About Commands
When the unit receives a command, it transmits the plus symbol: "+"
to confirm the command is executable. If the command is not correct,
the unit transmits the minus symbol: "-".
When the parameter of a command is out of range, the unit sends:
"- [PARAMETER_ERROR]".
The unit receives continuously input characters from host but they
are hold only if the panel switch "Local-Remote/Serial" is on Serial.
If this switch is on Local-Remote and a character is received, the unit
sends:
"- [LOCAL_MODE]"
to inform that a character is received but it is not possible to execute
commands coming from the serial line.
When a command received is formally correct but can no be executed
because the status of the unit does not allow this, (for instance a
command: "A011" is sent but the cable interlock is not OK) the unit
sends:
"- [COMMAND_UNEXECUTABLE]"
to inform that the request is not coherent with the status of the unit.
