<Src> 000-0FF Allows you to specify the source of crosspoint switchover.
<ID> 0-FE Unit ID. The ID must be different from that of other devices in the same network. Use
1 to FE for ID numbers. The host returns 0 when the lock is released.

Echo and Prompt
Responses will be sent as shown below when receiving commands:
Receipt of command
↓
Echo @[sp]X:<Lvls>/<Dest>,<Src>[CR]
↓
Prompt [CR][LF]>
* MFR units respond with an Echo Reply with the same data received. Therefore, echo reply messages
end with [CR] [LF] or [CR] only. If echo messages with [CR] [LF] are received, only [LF] composes the
second line.
* MFR units read a command, ended with a newline, and return a prompt to notify that they are ready to
receive a new command.
*
A carriage return and line feed are not added at the end of “Echo Reply” or “Prompt”
 “C” responses
A “C” response is sent as shown below when a control command is received:
[CR][LF]C:<Lvls>/<Dest>,<Src>[
…
[S< Salvo number >][L< Link number >]]:I<ID>[CR][LF]
* C responses are sent to all terminals in the system.
