System operation commands

7.1 Crosspoint Take

This command directly takes the specified crosspoint. The command specifies which inputs
to connect to which outputs and on what levels. Several crosspoint takes can be specified
on a single command line. In such cases all specified crosspoints are taken simultaneously.

<command> ::= 'x' <crosspoint> {<crosspoint>}

<crosspoint> ::= 'l'<levels> <in_out_pair> {<in_out_pair>}
<in_out_pair> ::= <in> <outs>
<outs> ::= <out>|<out>','<outs>|<out>'-'<out>

A single Crosspoint Take command can switch multiple crosspoints. You will however
receive one status message for each crosspoint that is switched.

<in>

Input number in the range from zero to one less than the number of
inputs on the level. <in> can also be one of the following characters:

d

Disconnect. Used when a destination is not connected to any
source.

o

Out of range. Used when a destination is connected to a source
not included in a level. This may occur with overlapping partitions.
Only valid in the response.

u

Undefined/Unknown. This might be used at start-up before the
status is read from the physical router. It is also used on ported
routers where a port can be used as an input or an output. Only
valid in the response.

<out>

Output number in the range from zero to one less than the number of
outputs on the level.

Examples:

Command

Desired action

x l3 52 27

Switch input 53 to output 28 in level 3.

x l1,2 2 4-6,8 Switch input 3 to output 5, 6, 7 and 9 in levels 1

and 2.

x l37 1 1 2 2 In level 37 switch input 2 to output 2 and input 3 to

output 3.

7.2 Order of execution

The following rules apply:

For all crosspoints specified directly or indirectly through the use of virtual tables

and salvos, the commands will be executed as soon as possible.

All crosspoints residing in the same router will be switched at the same video line if

this is supported by hardware.

No further guaranties are given for time of execution.
