SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective equipment
and signal distribution systems. Become familiar with the equipment that you are
working with and observe the following safety precautions.
Every precaution has been taken in the design of your Digital Media Gateway to insure
that it is as safe as possible. However, safe operation depends on you the operator.
Always be sure your equipment is in good working order. Ensure that all points of
connection are secure to the chassis, and that protective covers are in place and secured
with fasteners.
Never work alone when working in hazardous conditions. Always have another person
close by in case of an accident.
Always refer to the manual for safe operation. If you have a question about the
application or operation call Sencore for assistance.
WARNING –To reduce the risk of fire or electrical shock never allow your equipment to
be exposed to water, rain or high moisture environments. If exposed to a liquid, remove
power safely (at the breaker) and send your equipment to be serviced by a qualified
technician.
To reduce the risk of shock the DMG 1200 must be connected to a mains socket outlet
with a protective earthing connection.
For the DMG 1200 the mains plug is the main disconnect and should remain readily
accessible and operable at all times.
The DMG 1200 is equipped with an internal system battery. The DMG must be sentto
Sencore’s service department for replacement.
CAUTION –Danger of explosion if battery is incorrectly replaced. Replace only with the
same or equivalent type.
When installing the DMG 1200 utilizing the DC power supply, the power supply MUST be
used in conjunction with an over-current protective device rated at 250V, 15A, type:
Slow-blo, as part of battery-supply circuit.
FCC Class A Information
The DMG 1200 has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This

Introduction
The DMG 1200 is a Digital Media Gateway used as a digital turnaround product capable of
converting up to 32 transport streams from ASI to IP, IP to ASI, or any combination in between.
The DMG 1200 comes standard with IP and ASI I/O to offer flexibility for future changes in
network architecture or sourcing content from two different interfaces.
This manual describes how to install, configure, and operate the DMG 1200 Digital Media
Gateway. It is written for professional operators of video distribution systems and assumes a
prerequisite level of technical knowledge.
The DMG 1200 is controllable through the web interface or SNMP to perform tasks such as
setup, monitoring, and troubleshooting. The front panel provides simple status and IP information
for accessing the unit.
Supported WEB interface browsers include:
- Internet Explorer 7 & above
- Mozilla Firefox 3.5 & above
- Chrome

Hardware Layout
The DMG 1200 platform is designed to offer operators reliability and flexibility. The unit consists
of a chassis in which up to two platforms can be installed. To cater to specific system
requirements, the chassis can be configured to host optional modules best suited for a given
scenario.
DMG 1200 Chassis
The Sencore DMG 1200 platform can be delivered in various combinations. The basic single
DMG platform includes redundant power supplies, Ethernet control port, 2 MPEG/IP I/O NICs,
and 4 bi-directional ASI ports. The chassis shown in Figure 1 is a basic single DMG platform.

A dual DMG platform has 2 options for adding additional ASI inputs/outputs:
1. Additional 4 ASI inputs (for one or both platforms)
2. Additional 4 ASI outputs (for one or both platforms)
The chassis shown in Figure 3 has dual platforms with (8) additional ASI outputs. Platform 1 is
on the bottom and Platform 2 is on top. Each platform is independent from one another for
stream routing.

Control Ethernet Connection
A standard RJ-45 connector provides connection to the SNMP and web interface of the DMG
1200. The connection is a 10/100 BaseT connection. A user can view the IP address of the unit
from the front panel or once known can access the web interface through any supported web
browser by typing the IP address of the unit. The control port is capable of both DHCP and static
IP addressing. By default the IP address of the DMG 1200 is dynamically set to DHCP.
