NOTICE

1. A line of Rs485 may control up to 32 main

controlling and under controlling equipments,

so a keyboard which controls the dome directly

may connect up to 31 domes.

2. The system may connect up to 4 keyboards at

the same time, and the four keyboards ID are

different.

Connection

The keyboard and camera connects in parallel with the 

RS485 Bus and each keyboard can control each dome. This 

way is required because you need to have the keyboard's 

(the main keyboard ID is set to '1') Baud rate set to 9600bps 

(see picture 2-4-2).
