sub-standard, it is recommended to check the Video Settings of the KBC Encoder.
There are no resolution settings on the decoder interface.

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 decoder: TX+ to PTZ Control:

TX+ (or “A”)

From decoder: TX-

to PTZ Control:

TX- (or “B”)

2.2.6.2 RS-422, 4-wires

(Use default RS-422/485 dip switch selection)
From decoder: TX+ to PTZ Control:

TX+

From decoder: TX-

to PTZ Control:

TX-

From decoder: RX+ to PTZ Control:

RX+

From decoder: RX-

to PTZ Control:

RX-

2.2.6.3 RS-232

(Use RS-232 dip switch selection)
From decoder: TX+ to PTZ Control:

Transmit

From decoder: RX+ to PTZ Control:

Receive

From decoder: GND to PTZ Control:

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.

2.2.7.2 Default Audio Configuration

The audio is default configured as disabled and must be enabled in the encoder for
audio in. Audio out does not have a selection, simply connect a speaker to the Audio
Out jack and ensure that the decoder Audio In is enabled.
