The DBC4R is a 4 output video amplier.
• There are 2 working modes: riser mode and distributor mode;
• Separate isolation protection without affecting another devices on bus system;
• Short-circuit indication for convenient maintenance;
• Periodic self-detection mechanism for recovery.
Impedance Switch:
Video match switch.
Bus:
Input port,bus connection port.
A,B,C,D:
Output port,connect to indoor monitors.

DIN Rail Mounting
Note:
• Operation mode: Protection mode will be activated once its connected devices are
short circuited, and power supply for ABCD outputs will be turn off, the ashing in-
use indicator shows the distributor is in the protection mode.
• Self-detection: System will auto check whether the short circuit is xed or not, then
recover the power supply, and in-user indication will be turn off;
• Detection period: Self-detection will be happened regularly according rules, and in-
use indicator will ash rapidly three times when check happens;
1st detection will be happened in 10 seconds after short circuit;
2nd detection will be happened in 60 seconds after 1st detection;
3rd detection will be happened in 5 minutes after 2nd detection;
4th detection will be happened in 10 minutes after 3rd detection;
5th hereafter detection will be happened every 30 minutes;
