This indicates that output 1 is connected to input 12 on level 1, and that output 2 is connected to

input 2 on level 1.

The number of digits used for each number is generally the maximum number of digits ever

required for that particular switcher. Thus, a switcher with between 10 and 99 inputs would use

two digits for the input number, and a switcher with less than 10 levels would use one digit for the

level number.

“C”: Clear Matrix

Use command C to request that the switcher matrix be cleared so that all outputs are

disconnected from inputs (in switchers where this is possible) or else all outputs at all levels have

input 1 as their source. This command can take several seconds to execute (depending on the

size of the switcher matrix). In order to help ensure that this command isn’t accidentally executed,

it requires four additional characters following the “C” character, to spell out the word “CLEAR” in

full. For example, the command:

**CLEAR!!

would clear the matrix and when finished — the following response would be generated:

**OK!!<CR>

“K”: Set Password

The command "K" is followed by a password, which may be 0 to cancel the previous password,

thus causing no password to be specified, or, it may be a value between 1 and 9999 to supply a

password, which remains in effect until another password (or password 0) is supplied in another

“K” command. The password is stored by the router under the remote address specified using an

“M” command, or under the control portís remote address if an “M” command was not specified

before the “K” command in the same command string as the “K” command. The password that is

set remains in effect until another “K” command is received from the same remote address.

It would be used to establish a password for a remote address, to be used for such things as

locking and unlocking outputs and modifying the router configuration. When the router receives a

protected command (one which requires use of a password) from a remote address, it compares

the current password for that remote address with the password required to execute the protected

command. Protected commands consist of many of the “G” commands that change router

configuration, as well as take and salvo trigger commands when the output to be taken is locked.

In the former case, the administrator password is the one that must be sent in the “K” command

to permit the router configuration to be changed, while in the latter case the password that was

used to lock the output is the one that must be sent in the “K” command to permit the take to

occur.

Refer to the “B” command and the “G ADMIN_PASSWORD” command (in a separate document)

for more information.

For example, the command:

** M197 K1777 !!

1 2 ... 39 40 41 42 43 44 45 46 47 48 49 ... 67 68
