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 encoder 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 decoder, 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 encoder into RS-232 mode.
2.2.4 Status LED Description
The KBC Encoder 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 camera is sending communication to the encoder.
3. Data TX. LED should remain OFF unless PTZ control signals are
being sent from the decoder (Transmitted to the camera).
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.
Note:
If the LAN port LEDs do not light up, check Ethernet cable or connected
Ethernet device.
2.2.5 Composite Video Connection
Make all Video In coaxial connections prior to powering up the encoder. If the video
input is connected after power is applied to the encoder, the unit will require a power
