Chapter IV Matrix Controlling
This chapter introduces matrix controlling and programming via the
keyboard. Make sure the keyboard has been correctly connected to
the matrix switcher prior to operation. Preset and other special
functions mentioned in this chapter are all based on Manchester
protocol. For other protocols, user can refer to corresponding
product manual.
4.1Communication between Keyboard and Matrix
Communication between V2125 keyboard and Infinova matrix
switcher can be established by RS-232 or Ethernet.
1. RS232 Communication
Connect RS-232 port on the rear panel of V2125 to RS-232 port of
any matrix switcher, as shown in Figure 4-1:

2. Ethernet Communication
Route the Ethernet port on the rear panel of V2125 via Hub to the
Ethernet port on the matrix switching system, as shown in Figure
4-2:

4.2 User Login
To assure system security, certain matrix models, V2040 for
example, require a User Login procedure to access system functions.
Under such circumstances, it will prompt "Enter Username" and
"Enter Password" messages on the LCD, which require user to enter
a valid user name and password. Only by entering a valid user name
and its password can you access the keyboard functions such as
video switching and menu programming.
To login the system
1.
Enter a correct username;
2.
Press ACK key, a "Password:" prompt will be displayed
on the LCD;
3.
Enter the password (up to 6 digits);
4.
Press ACK key to confirm. If the "Password:" message
has been cleared from the LCD, it indicates a successful
login, i.e., the user has been authorized to perform
system operation on the keyboard. If there’s an error,
user should enter the password again.
Note:
To ensure system security, it is recommended that the current
user should logoff before leaving the system idle for some time.
To log off the system
Press USER key, and there’ll be "Username:" displayed on the LCD,
indicating a new User Login procedure will be required for system
access.
