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 300D 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 300D must be connected to a mains
socket outlet with a protective earthing connection.
•For the IMPULSE 300D the mains plug is the main disconnect and should remain
readily accessible and operable at all times.
The IMPULSE 300D is equipped with an internal system battery. The IMPULSE
300D must be sent to Sencore service for replacement of this battery.
CAUTION –Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type.

2.1 Rack Installation
The IMPULSE 300D unit can be easily deployed almost anyplace. 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
300D. Only use the supplied 3-prong power connector or one withequal specifications.
NEVER tamper with or remove the 3rd –prong grounding pin. This could cause
damage to the IMPULSE 300D, personnel, or property.
2.3 AC Power Connection
The IMPULSE 300D 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 300D.
2. Plug the female end of the power cord (end with no prongs) into the back of the
unit.
3. Locate a protected outlet (usually inside of the rack) to plug the male end of the
power cable into.
2.4 Maintenance
The IMPULSE 300D is virtually a maintenance-free piece of equipment. There are no
user serviceable parts on the inside of the unit.

3.1 IMPULSE 300D Front Panel Overview
The IMPULSE 300D 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 300D. This idle screen shows the incoming
bitrate of the active input and output as well as the management IP addresses of the
unit.
1. Active input and bitrate of incoming stream
2. Output format 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 300D 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 300D must first be configured properly for the network it is connected
to. By default, the IMPULSE 300D 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
3.2.1 Configuring IP Mode (Static or DHCP)
To setup the IMPULSE 300D 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.
