* [sp] indicates a space.
* Commands must end with a carriage return (ASCII code 0x0D) only or carriage return and line feed (ASCII code
0x0A). MFR units add a carriage return and line feed in front of and at the end of reply messages.
Command parameters and setting range
<Lvl>
0 - 7
Allows you to specify the level to switch crosspoints.
* When in single-level operation.
<Lvls>
0 - 7
Allows you to specify the levels to switch crosspoints.
* When in multiple-level operation
<Dest>
000 - 03F
Allows you to specify the crosspoint switchover destination.
<Src>
000 - 07F
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.
* All command values are in hexadecimal, starting from 0 (zero).
(For example, Source “16” is represented as <Src>”F.”)
* If levels are not in use, set <Lvl> or <Lvls> to “0”(zero).
4-3-1. Command Responses
 Echo and Prompt
Responses will be sent as shown below when receiving commands:
A command is received.
↓
Echo
@[sp]X:<Lvls>/<Dest>,<Src>[CR]
↓
Prompt
[CR][LF]>
* MFR units respond with an Echo Reply with the same data that they 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” and “Prompt”
 “C” responses (Commands 1-6)
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 the terminals in the system.
