reset in order to stream video to a connected decoder and/or via the encoder GUI
video display.
The Video Out Composite BNC is an analog video loop through from the Video In
BNC. This provides an option to test the video out from a camera without
disconnecting the encoder and requiring a power reset to the encoder. Viewing video
from the Video Out BNC will not identify whether the encoder is actually encoding
the video, however, the encoder must be powered up to view the video from the
Video Out composite BNC. A video cable can be connected from the Video Out BNC
to a monitor after the encoder has been powered up without requiring a power
reset.
Note: If the connected camera loses power but the encoder does not, the encoder
must be power reset once the camera is back online.
2.2.6 Data Protocol Dip Switch Selection & PTZ Wiring Schemes
The following PTZ data schemes have been tested by KBC. Other wiring
combinations are possible depending on the PTZ system manufacturer.
Note: A solid RX light indicates an improper data wiring connection. If one of the
following schemes results in a solid RX LED, check the protocol dip switch
selection and/or use a varying wiring combination if your PTZ system requires
a different wiring solution.
2.2.6.1 RS-422/485, 2-wires
(Use default RS-422/485 dip switch selection)
From encoder: TX+ to camera:
RX+ (or “A”)
From encoder: TX- to camera: RX- (or “B”)
2.2.6.2 RS-422, 4-wires
(Use default RS-422/485 dip switch selection)
From encoder: TX+ to camera:
TX+
From encoder: TX- to camera: TX-
From encoder: RX+ to camera: RX+
From encoder: RX- to camera: RX-
2.2.6.3 RS-232
(Use RS-232 dip switch selection)
From encoder: TX+ to camera:
Transmit
From encoder: RX+ to camera: Receive
From encoder: GND to camera: Ground
2.2.6.4 Known Incompatible Protocols
The following data protocols are not supported by the KBC encoder/decoder:
 Sensornet
 Biphase & Bilinx, other Bosch proprietary protocols
 Kalatel protocols using RS-422. The system is compatible in RS-485 at 9600
Baud Rate
 Coaxitron or any “up the coax” PTZ control systems
2.2.7 Bi-Directional Audio Parameters
2.2.7.1 Needed Audio Equipment
 The mic/speaker audio in/out jack must be connected via stereo cable.
 The audio source for Audio In must be amplified; the encoder does not
provide amplification on the audio.
