FUNCTIONS
1. RS485 CONNECTION
Used when the RS485 mode is chosen in the Junction Box. Shielded Twist Paired Cable is
recommended. In case of using AWG28 cable, this receiver can send the data up to
1.2Km away. (It may differ from real spots)
In COMM SEL box, you must cover the Pin on which 'RS422/485' is written with the
socket.
Notice: There are 2 sets of Camera Control Ports in the Keyboard Controller (DCK-255),
and each of them can be connected to up to 128 receivers in parallel.
