Tx1500/KBD - System Keyboard
This Keyboard provides control of the system and any cameras connected to the matrix. The Keyboard communicates through
an RJ45 connector using BBV Tx1500 protocol at 9600 baud on an RS422 link.
The Keyboard requires 12Vdc supply, minimum current of 100mA. Keyboards will need separate power supplies after 4+
keyboards are used, which are supplied as standard with each Keyboard. Additional power supplies can be obtained from BBV.
Each Keyboard must have a unique address between 1 and 8. Keyboards sharing the same address will not be recognised by
the matrix and unpredictable operation will occur.
Setting a keyboard number
1. When powering up the keyboard you
should see the 'Camera' and
'Monitor' buttons light up.

following page to determine which keyboard
is selected).
4. Once happy with your keyboard selection, you can
either leave the keyboard for a few seconds until
it exits config mode, or you can power down the

keyboard settings.
