1 1 1 1 Varies 1 1 1 <= size in bytes



Read = ‘R’ or <52>, Write = ‘W’ or <57>



Device number of the sender: <7F> is normally used.

The bytes in RED can be inserted many times inside a single Protocol String. There is no limit in the number of

<HEADER><VALUE> combo as long as the whole block (from <01> to <02>) is less than 256 bytes. When a

<HEADER><VALUE> is received, the corresponding new parameters are stored in the memory. However, it is

processed only when a <PROCESS> (<1F>) is received. The <PROCESS> can be inserted more than once if multiple

actions are desired, eg. Mute multiple channels at the same time.


The <HEADER> is used to identify the types of value following the header.

Command Header <03 to 07>; <03> = 4 bytes <VALUE>… <07> = 8 bytes <VALUE>

Command ID in ASCII character

Device Header

<08> Device # where this command is sent to

I/O Header

<09> Input / Output section of the device

Channel Header

<0A> Channel #

Aux Header

<0B> For extra information such as EQ Num, FBX Num ,etc

Column Header

<0C> Used in Special Commands like Level Increment

Data Header

<10 to 18>; <10> = 1 byte <VALUE> … <18> = 9 bytes <VALUE>

The parameter data value to be changed


<VALUE> must always follow the <HEADER>.

Command Value

For the commands, related table in this document

Device Value

<20> for Device 0... <2F> for Device 15

I/O Value

<20> for Input, <21> for Output

Channel Value

<20> for Channel 0... <27> for Channel 7

Aux Value

<20> for Aux # 0... <1F> for Aux #31

Column Value

Used in Special Commands, see related table in this document

Data Value

For the list of Data values, see related table in this document

Note: For Data values > <60> (96 in decimal), convert the data into a Base 96 number. Add <20> to each digit to get

the Hex bytes. This restricts all Data value hex bytes between <20> and <7F>.
