Suite 16 Serial Protocol V1.4 Explanation
PURPOSE:
This document explains the serial data code structure and operation of the Suite 16 Multi-
Room Preamplifier. This document is preliminary and is for Suite 16 Audio card with version
1.4 software. All content subject to change.
DISCUSSION:
The Suite 16 Multi-Room Preamplifier is serial controlled at 19200 baud or 1200 baud. The
10 character command structure is as follows:
START CHARACTER ACTION
FUNCTION
ROOM#/GLOBAL
<CR>
Example
‘
S or G
AD01
R01
<CR>
The above example demonstrates how you would set room 1 to analog input 1. The start
character must always be a ‘ called an accent grave, located on the key next to the 1 key on
a standard QWERTY keyboard. All letters used in a 10 character string must be upper case.
The end of the string must always end in a carriage return or “ENTER” key. The second
character is “S” for set when performing a function. When updates about system status are
requested this character will be a “G” for get. The third through sixth characters are the func-
tion code. Referring to the excel sheet you can look up the various functions that the pream-
plifier can perform. In some cases, like the volume direct command, some of the characters
are a value entered into the system. The seventh through ninth characters are for telling the
system that the command is for a specific room or a global function. Like the function code,
some of the characters can be a variable for certain functions.
After there is a power failure and power is restored, the system will return to the last active
settings for every room including whether the room was on or off, tone controls, volume, input
trim, balance and input selected. The exception being if any page mode had been activated
by serial command it will be cancelled. If a page mode is being activated manually or by auto
audio level detection then the page will be active on power up.
The feedback response is an 11 character string
START
Acknowledge
PLACE
FUNCTION
ROOM or
CHAR
HOLDER
GLOBAL
Example
‘
A
X
AD01
R01
<cr>
The “A” is for acknowledge and is in every feedback response
The “X” is a placeholder but is used only for feedback in the volume, tone and balance
presets
