Stand-alone Operation
The Control I/O may also be used in a stand-alone fashion or integrated into other RS-485 compatible control systems such as
those made by AMX or Crestron. All previous hook up information applies as well as device addressing information (with the
exception of DIP switch #1 “ASCII / Studio Matrix”, which should be down in the “ASCII” position and then the unit power cycled
to enable stand-alone mode). The REMOTE ARC ports will not be of use in this application as the ARCs do not use the protocol
outlined below.
ASCII Control Protocol
Introduction
The Control I/O has the capability of being used as a generic control device, without the Studio Matrix system being present. In
this mode, the device accepts generic commands from the RS-485 input and respond accordingly. This section outlines how that
is accomplished, and the commands supported by the device.
Control I/O Setup
Setting the second DIP switch from the left (looking from the rear) to the ‘on’ (down) position puts the Control I/O into the ASCII
control mode. After changing modes, the unit will need to be power cycled for the setting to take effect. While in the ASCII
control mode, the unit will not respond to normal Studio Matrix commands, but instead to a simple ASCII based protocol suitable
for AMX/Crestron type controllers or even a simple terminal program.
Command Set
The
<address>
field must match the value of the address on the specific unit’s DIP switch. If the address field does not
match, then the command is ignored and no response is sent which allows multiple units to reside on the same RS-485 bus.
If the address is correct but the command isn’t recognized, or any of the parameters are incorrect, a
NAK
will be returned.
The address field can range from
0-31
. If everything was satisfactory, an
ACK
will be returned. Parameter values can be
separated by space(s) or a comma, though numeric parameters directly following a character value need no delimination. All
numeric parameters are positive decimal integers except for the
Send MIDI String
command which accepts a string of two digit
hexadecimal numbers.
(FU) Flash Front LEDs
Command:
FU <address><cr>
Where
<address>
is a decimal number
0-31
.
Response:
<ACK/NAK><cr>
(RV) Return Software Version
Returns the current firmware version of the Control I/O’s microcontroller.
Command:
RV <address><cr>
Response:
<value> <ACK/NAK><cr>
Where
<value>
is the version number times 100.
(IM) Set Input Mode
Command:
IM <address> <input> <mode><cr>
Where
<input>
is a decimal number
1-8
and
<mode>
is:
P
= potentiometer
E
= encoder
S
= dual switch
Note:
Input modes are persistent with power cycling. A new unit from the factory will set all 8 inputs as dual switches.
Response:
<ACK/NAK><cr>
If
<input>
is outside the
1-8
range, or
<mode>
is not “
P
”, “
E
”, or “
S
” then a “
NAK
” is returned.
