Cross Protocol Mix Control
When the junction box is powered, it will provide power to the keyboard via any port that it is
connected to i.e., RS232, IP, RS422(A), RS422(B).
Therefore, no additional power supply is required for the keyboard if a powered junction box is used.
NOTE: Regarding Serial Control protocols (RS422/RS485 and RS232):
•
When controlling only RS232 cameras, the keyboard can control a total of 7 RS232 cameras.
•
When controlling RS422 and RS232 cameras simultanneously, the keyboard can control a
total of 7 RS232 and RS422 cameras.
•
When controlling only RS422 cameras, the keyboard can control up to 14 RS422 cameras (2
daisy chains of 7).
•
When controlling only RS485 cameras, the keyboard can control up to 255 RS485 cameras.
The keyboard is capable of simultaneously controlling up to 255 cameras, between mixed protocols
(RS422, RS232, and IP).
