This following pages outlines the operation of the Matrix Web-GUI. Connect the TCP/IP RJ45 socket to the local
network in order to access the products Web-GUI, or connect a PC directly to the TCP/IP port for initial configuration.
By default the Matrix is set to DHCP, however if a DHCP server (eg: network router) is not installed the matrix IP address
will revert to the below details:
Default IP Address: 192.168.0.200 Default Username: blustream Default Password: 1234
The Web-GUI supports multiple users along with multiple user permissions as follows:
Guest Account - This account does not require a user to login. The Guest account can only change sources for each
zone. Guest access can be changed by the Admin, limiting inputs or outputs as necessary.
User Accounts - 7x User accounts can be utilised, each with individual login details. User accounts can be assigned
permissions to specific areas and functions. A User must log in to make use of these functions.
Admin Account - This account allows full access to all functions of the Matrix, as well as assigning users with individual
permissions.
Web-GUI Control
The Blustream range of matrix products include Matrix control via IR.

RS-232 Configuration and Telnet Commands
The Blustream matrix can be controlled via serial and TCP/IP.
RS-232 port 1 is used for configuration and control of the product. RS-232 port 2 is used for cascading multiple
MX44KVM units together to create a larger I/O KVM matrix system, or when used in conjunction with a Bustream AV
matrix to add KVM switching to a larger system.
The default RS-232 communication settings for both ports are:
Baud rate: 57600
Data bit: 8
Stop bit: 1
Parity bit: none
The following pages list all available serial commands for RS-232 port 1:
Commonly used Serial Commands
There are several commands that are commonly used for control and testing:
STATUS Status will give feedback on matrix such as zones on, type of connection etc...
PON Power on
POFF Power o
USBOUTxxFRyy (xx is the Host / zone out, yy is the USB Device input)
Example:- OUT01FR04 (This would switch host 1 to device 4)
Common Mistakes
• Carriage return – Some programs do not require the carriage return, where others will not work unless included
aer / within the string. In the case of some Terminal soware the token <CR> is used to execute a carriage return.
Depending on the program you are using this token maybe dierent. Some other examples that other control systems
deploy include \r or 0D (in hex)
• Spaces – Blustream commands do not require space between commands unless specified. There may be some
programs that require spacing in order to work.
- How the string should look is as follows OUT01FR02
- How the string may look if spaces are required: OUT{Space}01{Space}FR{Space}02
• Baud rate or other serial protocol settings are not correct
