UDM-0808-SIG Wiring and Connections

UDM-0808-SIG, UDM-RX02N and UDM-ABB-8-SIG Operation /Reference Guide
Two major factors that can affect the quality of signal transmission include:
Cable Distance: Long distance cable runs (in excess of 300 meters/1000 feet) are subject to
resistance and capacitance losses which can negatively impact the quality of the image.
Skew: "Skew" represents the slight delay that results from the variation in wiring lengths for each
of the twisted pairs. The effects of skew on A/V signals increases with cable length. Excessive skew
can adversely affect video image quality, especially at long cable lengths and high signal
resolutions.
NETWORK Port (RJ45)
The NETWORK (RJ45) port provides 10/100 BaseT network connectivity. The following table lists the
pinouts, signals, and pairing for the Network port.
FIG. 9 diagrams the pinouts and signals for the Network RJ45 connector and cable.
By default, the UDM-0808-SIG is configured for DHCP. Refer to the IP Settings section on page 29 for
details.
SERIAL (RJ12) Port
The SERIAL (RJ12) port on the rear panel is available for diagnostic and troubleshooting purposes. The Serial
port on the UDM-0808-SIG is an RJ12 connector, and requires a DB9-to-RJ12 adapter cable (FG-RS01
, not
included
) to connect to a PC for Terminal control.

Consult the Network Administrator for correct cabling from the UDM-0808-SIG onto
the network. For remote connectivity, the Firewall may have to be configured to open
port
2008
for remote connectivity over UDP
Connecting the SERIAL port on the UDM-0808-SIG is not an essential step in the
installation process.
