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 Impulse 300E to ensure
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 Impulse 300E must be connected to a mains socket
outlet with a protective earthing connection.
•For the Impulse 300E the mains plug is the main disconnect and should remain
readily accessible and operable at all times.
The Impulse 300E is equipped with an internal system battery. The Impulse 300E
must be sent to Sencore service for replacement of this battery.
•To reduce the risk of shock and damage to equipment, it is recommended that the
chassis grounding screw located on the rear of the Impulse 300E –be connected
to the installation’s rack, the vehicle’s chassis, the battery’s negative terminal,
and/or earth ground.
CAUTION –Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type.

1.1 Product Introduction
The Impulse 300E - Internet Streaming Encoder, is a versatile and easy-to-deploy
MPEG2 and H.264/AVC encoder. The Impulse 300E is useful for acquiring,
compressing, and delivering video and audio content across local or public IP networks.
The unit is fully controllable through the web interface to perform tasks such as setup,
monitoring, and troubleshooting
This manual describes how to install, configure, and operate the Impulse 300E Internet
Streaming Encoder. This unit is also backed by Sencore’s best-in-class staff of ProCare
support engineers.
1.2 Front Panel Overview
The Impulse 300E’s physical IP addresses can be configured through the front panel
using the LCD screen and buttons that are shown below. A description of using the front
panel can found in Section 3.1.

1.4 Cooling
The Impulse 300E is cooled via forced induction through the front of the unit and
exhausted through the vents in the rear and sides of the chassis. The Impulse 300E is
equipped with a temperature controlled status indicator. If the unit temperature exceeds
70° C the red “Error” text will illuminate on the front panel and a description of the error
will appear in the “Error List.”
1.5 Rack Information
The Impulse 300E is versatile and was designed to be deployed as a standalone device
for easy installation into locations with limited space. With the optional SDI2X-MOUNT
kit, three (3) Impulse 300E units can be deployed in a standard 19”.

2.1 Installation
The Impulse 300E unit can easily be deployed almost any place. The size is small
enough that the unit can be placed on a desk, in an equipment rack or on a shelf at a
test bench.
2.2 Power Connection
Using the proper power connections is vital to the safe operation of the Impulse 300E.
Only use the supplied 3-prong power connector or one with equal specifications. NEVER
tamper with or remove the 3rd –prong grounding pin. This could cause damage to the
Impulse 300E, personnel, or property.
2.3 AC Power Connection
The Impulse 300E is intended for use on either 120V or 240V systems. The power supply
will automatically detect the system it is connected to. To hook up the power use the
following steps:
1. Locate the AC power cord that was included with the Impulse 300E.
2. Plug the female end of the power cord (end with no prongs) into the back of the
unit.
3. Locate a protected outlet to plug the male end of the power cable into.
2.4 Maintenance
The Impulse 300E is virtually a maintenance-free piece of equipment. There are no user
serviceable parts on the inside of the unit.

3.1 Impulse 300E Front Panel Overview
The Impulse 300E front panel allows configuration of the network interface settings,
application of profiles, and viewing alarm statuses and unit information. The screen
below is the idle screen of the Impulse 300E. This idle screen shows the active input
type and output type/bitrate, as well as the IP addresses of the unit’s network interfaces.
1. Active input
2. Output type and bitrate
3. IP address of “Network 1” interface
4. IP address of “Network 2” interface
The figure on the next page shows a typical screen on the front panel. Several important
features have been circled and noted. These features are common to all screens and
assist when navigating, viewing, and editing unit information. The button allows the
user to return to the home screen, cancel settings and go back a menu. In order to edit a
selected parameter the button must be pressed. Once a parameter has been
changed the button must be pressed again before the change takes effect on the
unit.

3.2 Network Setup via Front Panel
The Impulse 300E can be setup on a network connection to allow remote management
and SNMP configuration. For these features to work, the network settings for the
Impulse 300E must first be configured properly for the network it is connected to. By
default, the Impulse 300E follows this configuration scheme:
•Network 1:
oMode: DHCP
•Network 2:
oMode: Static
oIP Address: 10.0.0.72
oSubnet Mask: 255.255.255.0
oGateway: 0.0.0.0
Configuring IP Mode (Static or DHCP)
To setup the Impulse 300E with a static IP address, use the following steps:
1. Press the button (twice if the front
panel is in “Idle” mode).
2. Use the and buttons to
move the cursor to “Admin”, then press
the button.
3. Use the and buttons to
move the cursor to “Unit Networking”,
then press the button.
