must

 

be

 

immediately

 

followed

 

with

 

a

 

<CR>

 

(0D

 

hex)

of

 

transmission.

• 

All

 

single

 

digit

 

channel

 

addresses

 

must

 

have

 

an

 

ASCII

 

0

 

zero

 

preceding

 

them.

 

00

 

is

 

not

 

a

 

valid

 

channel

 

number.

 

   

Example:

 

01,02,03

 

• 

All

 

channels

 

addressed

 

in

 

the

 

“multi

 

channel

 

format”

 

described

 

below

 

must

 

have

 

commas

 

as

 

separators

 

between

 

channel

 

   

numbers.

 

01

99

 

is

 

the

 

valid

 

range.

 

Example:

 

MI,01,50,99<CR> 

• 

Commands

 

may

 

be

 

combined

 

with

 

the

 

asterisk

 

*

 

(2A

 

hex)

 

command

 

separator

 

character

 

to

 

form

 

a

 

single

 

command

 

   

transmission

 

string

 

as

 

in

 

the

 

following

 

format

 

Example:

 

MI01*SO01,99*MI02*BO16,32<CR>. 

• 

Each

 

command

 

must

 

be

 

5

 

characters

 

minimum

 

in

 

length

 

including

 

the

 

<CR>

 

character.

 

Single

 

combined

 

command

 

strings

 

   

cannot

 

exceed

 

48

total.

 

• 

Because

 

there

 

is

 

no

 

report

 

back

 

of

 

switcher

 

channel

 

status

 

to

 

the

 

host

 

computer

 

from

 

the

 

switchers,

 

it

 

is

 

highly

 

   

recommended

 

that

 

a

 

global

 

command

 

such

 

as

 

BN<CR>

 

preface

 

all

 

switching

 

commands.

 

This

 

way

 

you

 

will

 

always

 

know

 

all

 

   

channels

 

are

 

off

 

before

 

turning

 

any

 

channels

 

on.

 

Other

 

approaches

 

are

 

valid,

 

but

 

require

 

keeping

 

track

 

of

 

enabled

 

channels

 

   

in

 

the

 

host

 

software.
