EMISSIONS REQUIREMENTS
FCC CLASS A
NOTE
: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to Part 15 of FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
WARNING
: Charges of modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
CANADIAN EMISSIONS
This digital apparatus does not exceed the Class A limits for noise emissions from a digital apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications.
Le present appareil numerique n'emet pas de bruits redioelectriqes depassant les limites applicables aux appareils numeriques de la Class A prescites dans le Reglement sur le brouillage redioelectrique edicte par le ministere des Communications du Canada.

CHAPTER 1 - DESCRIPTION
The DBU-HSSI is designed for use in receive only data broadcast applications.
Examples of typical data broadcast applications are; continuously updated private or public data displays and distribution of continuous data to PC's or Routers. The expanding role of VSAT systems in receive only applications for real time data distribution is expected to increase dramatically over the next few years. The
DBU-HSSI is an excellent choice for applications of this type.
The DBU-HSSI utilizes an ECL balanced interface with a maximum data rate of up to
52Mbps. Additionally, the unit has HSSI compliant voltage levels pinned to standard female EIA DB-25 connectors.
The DBU-HSSI continuously broadcasts receive data and receive timing. The
DBU-HSSI's master port should be connected to the HSSI transmitter(DCE device).
The input signals are split with the internal circuitry and rebroadcast out on the four output ports. All output ports should be connected to DTE devices.
The DBU-HSSI is housed in a sturdy aluminum enclosure and is supplied with an internal linear power supply. The unit has a 110/220 VAC rotary select switch located on the rear of the housing. The unit can operate on standard AC power found in all countries.

CHAPTER 2 - BASIC OPERATION
Operation of the DBU-HSSI is as simple as plugging a male DB-25 cable into the female DB-25 MASTER port on the back panel and plugging up to four male DB-25 connectors into Ports 1 - 4. Data and Clock are received on the Master Port and are broadcast out simultaneously on ports 1 - 4. The following table shows the pin-out for the Master and sub-channel ports.

CHAPTER 3 - SETUP AND INSTALLATION
POWER CONNECTION
It is very important to check that the unit is set to the correct voltage setting for your application before applying AC power. Located on the rear of the unit you will find a rotary 110/220 VAC switch. Using a coin or small screwdriver, gently turn the switch to the appropriate power position as required for your installation (110 or 220 VAC).
INSTALLATION
Connect the main input data feed source into the MASTER port DB-25 female connector. The output ports are marked PORT 1 through PORT 4. Connect from one to four DTE HSSI (ECL) compliant devices into the sub-channels ports on the back of the unit.
CABLING REQUIREMENTS
High quality shielded cables are recommended. It is very important to use the correct cable types. The following is recommended (or equivalent).
Cable type: multi-conductor cable, consisting of 25 twisted pairs cabled together with an overall double shield and PVC jacket

EQUIPMENT GROUNDING
A Jumper provides for grounding interconnection in those systems requiring a connection between frame ground and signal ground. Remove the DBU-HSSI rackmount cover to locate the jumpers on the printed circuit card. Move the jumper to the front two header positions to connect the grounds, if your system requires such a connection. The factory default is NO CONNECT, the back two header positions.
