2.2.3 RS Protocol Dip Switch Selection

2.2.3.1 RS-422 / 485

The default configuration is set for RS-422 / 485. In the diagram below, white
represents the switch. The first four dip switches ON (in the up position) with the
last four OFF will set the decoder for RS-422 or 485 protocol.

Note:

The dip switches will not determine the Baud Rate. The Baud Rate must be
configured to match the encoder, camera and PTZ system.

2.2.3.2 RS-232

The reverse dip switch positions (i.e, first four OFF and second four ON) will change
the decoder into RS-232 mode.

2.2.4 Status LED Description

The KBC Decoder offers status LEDs for the power and data as well as on the LAN
port for link status and activity.

2.2.4.1 Data TX/RX LEDs

1. Power LED. Allow 30 seconds after power up to illuminate steady.
2. Data RX. LED should remain OFF on standard activity. Will flash to indicate

that the PTZ controller is sending communication to the decoder.

3. Data TX. LED should remain OFF unless data is being sent from the decoder

to the PTZ Control system.

Note:

A solid RX LED indicates a data wiring, or other data related error. If the LED
will not turn OFF, contact KBC for further details and/or return authorization
for repair.

2.2.4.2 LAN / WAN Port

4. Link Status. On/Off
5. Port Activity. Will flash rapidly when streaming video or other link activity.

Note:

If the LAN port LEDs do not light up, check Ethernet cable or connected
Ethernet device.

2.2.5 Composite Video Connection

The Video Out Composite BNC is an analog video representation of the selected
compression format and resolution generated from a KBC Encoder. If video quality is

PWR

White indicates the position of the switch
