APPENDIX A – SCI PROTOCOL AND INTERFACE

COMMAND: STORE SALVO

Creating a transaction to be stored in a salvo

is done exactly as a regular transaction except the

salvo symbol is the leading character. The

following example will store this transaction in

salvo 2 (@):

@A10C3O19 {RETURN/ENTER}

This is a split mode transaction stored in

salvo number 2 (@ = SHIFT 2),change level 1 (A)

to source ten (10) and level 3 (C) to source three

(3) of output (O) nineteen (19).

Multiple switches may occur upon a single

salvo command. This allows multiple input to

output switches to be preloaded and then switch

simultaneously upon the execution of the salvo. A

typical multiple output salvo would be entered like

the following string of commands;

! I 01 O 01 {RETURN/ENTER}

! I 02 O 02 {RETURN/ENTER}

! I 03 O 03 {RETURN/ENTER}

! I 04 O 04 {RETURN/ENTER}

! I 05 O 05 {RETURN/ENTER}

! I 06 O 06 {RETURN/ENTER}

! I 07 O 07 {RETURN/ENTER}

! I 08 O 08 {RETURN/ENTER}

! I 09 O 09 {RETURN/ENTER}

! I 10 O 10 {RETURN/ENTER}

! I 11 O 11 {RETURN/ENTER}

! I 12 O 12 {RETURN/ENTER}

! I 13 O 13 {RETURN/ENTER}

! I 14 O 14 {RETURN/ENTER}

! I 15 O 15 {RETURN/ENTER}

! A 16 B 64 O 16 {RETURN/ENTER}

(No spaces are used between any commands.)

This salvo command is set for Salvo 1 (!) and

switches inputs (I) one to fifteen (1 - 15) to outputs

(0) one to fifteen (1 - 15) respectively. The last

step of salvo 1 performs a split switch of input

level 1 (A) from source sixteen (16) and input

level 2 (B) from source sixty-four (64) to output

(O) sixteen (16). The salvo command is finished

with Return/Enter. The number of possible

transactions in a salvo is equal to the number of

outputs in the system. You can only change each

output once in any particular salvo. Switch

commands do not need to be in numerical order.

If multiple commands are entered for one output,

only the last command for that output will be

visualized after the execution of the salvo.

COMMAND: SALVO STATUS ALL

The status of a salvo can be examined by

prefixing the status command with the salvo

symbol.

!SA {RETURN/ENTER}

The example provided is for salvo 1 (!). This

example provides the status (S) for all outputs (A).

The difference between a normal status check

and a salvo status check is anytime a level is not

assigned (such as in a breakaway), the

unassigned inputs will display dashes "---" to

indicate these input levels will not be affected by

the salvo. The dashed lines would appear at

levels 3 (C) and 4 (D) of output 16 for the sample

salvo 1 given in the previous command

paragraph.

COMMAND: SALVO STATUS SINGLE OUT

Within each salvo a specific output can be

checked for the status.

#S9 {RETURN/ENTER}

The example command for salvo 3 (#) would

yield the current status (S) for output nine (9).

COMMAND: SALVO ERASE (clear)

There are six commands available to erase a

salvo or portions of a salvo. To erase an entire

salvo use the following command.

$Z {RETURN/ENTER}

In the example above, the command will take

salvo 4 ($) erase (Z) the entire contents:

To erase only a specific output , use the

command with an output limiter attached.

@Z14 {RETURN/ENTER}

This example for salvo 2 (@) erases (Z) all

input assignments for output fourteen (14).

A range of outputs within a salvo can be

erased as a group.

!Z11-18 {RETURN/ENTER}

This example for salvo 1 (!) erases (Z) all

input assignments for outputs eleven (11) through

(-) eighteen (18).

It is possible to erase only one level of a

salvo. The following command erases only the

level designated for all transactions listed in the

command string.
