2.3.4 Replacing / Adding a Decoder to an Existing Encoder/Decoder
System
When a replacement decoder is ordered after the original products have been in
deployment, the new decoder may need to be reconfigured if the old device was not
set to the product defaults. The KBC Decoder can also replace an SED series decoder
and connect to an SED series encoder if applicable. If an SED series encoder is in
use the easiest reconfiguration is to set the new decoder to the settings of the old
SED series decoder which is no longer in use. On the new decoder, remember to
update the TCP/IP Connect IP (the encoder to which the decoder must connect)
along with the encoder’s GUI access account and password. Contact KBC for further
details on this process.
2.3.5 Establishing a Connection to a KBC Encoder
When connecting the decoder to a KBC Encoder, the following items must be in
place:
Both of the LEDs on the encoder and decoder LAN port must be illuminated. When
video is streaming, the amber LED will flash rapidly.
Ensure that the video cable from the camera to the encoder is connected when
the encoder is powered down. Connecting it after encoder power up will require a
power reset.
The video source must be present and powered up. This can be verified using the
encoder Video Out composite BNC.
The encoder IP must be able to be pinged from the decoder side of the network
using a computer which is on the same subnet as the encoder/decoder devices.
The decoder must also be able to be pinged from the encoder side of the network
using a computer on the same static subnet as the encoder and decoder.
There must be sufficient throughput across the medium used to connect the two
devices. If insufficient throughput is available, the encoder can be reconfigured to
consume less network traffic.
The encoder and decoder must have their own individual network settings (i.e,
LAN or WAN IP, etc.)
The decoder must be configured properly in its “Connection Settings”
configuration screen to identify the appropriate encoder settings in order to
connect and stream the data from the encoder.
Note:
If a connection to a KBC Encoder cannot be established in the field or on a
network, KBC recommends a test with the decoder directly connected to its
mate encoder using a crossover cable. If the two units are connected via an
unmanaged switch

then the interface screen can be accessed from a web
browser in order to identify if a problem in configuration exists.
2.3.6 IP Utility Locating Software Tool
KBC Networks provides a software tool to search for the encoder and decoder IP
addresses. This tool is helpful for diagnostics and trouble-shooting if needed in the
installation. Visit KBC Networks’ website software tool at
and select “Software”. The needed tool is the IP
Utility, the second link on the software downloads page. The other tools listed on the
page are for other KBC products which may not apply to your application.

The encoder and/or decoder can also be connected to a properly configured
managed switch.
