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.
An internal 8 way DIP switch is used to set the keyboard address, RS422 termination and PROGRAM key
enable/disable.
Each keyboard must have a unique address between 1 and 4. Keyboards sharing the same
address will not be recognised by the matrix and unpredictable operation will occur.
