MODEL 1584-18/18S Splitter

1.0 General

1.1 Equipment Description

The Model 1584-18/18S* is one eight-way, 0.95 - 2.05 GHz, 0 dB gain splitter in a 1RU rack mount chassis

with redundant 100-240 ± 10% VAC power supplies. The splitter provides fused LNB DC power insertion and

surge protection on the RF input, and provides excellent RF characteristics. The splitter has eight outputs on the

back panel, and fused LNB power can be inserted on the input. Two individual 100-240 ± 10% VAC input

power supplies provide diode OR’d redundant power to the unit*. The LNB power line is separately fused. A

surge suppressor on the splitter input protects against high voltage transients. On the front panel, two green

LED’s indicate the presence of DC voltage from each of the two power supplies, and another green LED

indicates LNB power insertion. LNB voltage test points are also provided on the front panel to monitor the LNB

voltage. *LNB Power Insertion feature NOT available on 1584-18S model.

2.0 Installation

2.1 Mechanical - The 1584-18/18S consists of one RF printed circuit board (PCB) housed in a 1 RU (1.75 inch

high) by 12 inch deep chassis. Redundant, switching, +24 VDC power supplies with the DC output diode OR’d

provide redundant power for the internal and external amplifiers and LEDs. (Model 1584-18/18S has a single

non-redundant, switching power supply). Connectors are type F, female for the RF connections (BNC, female

option -B or -D). The 1584-18/18S can be secured to a rack using the 4 holes on the front panel. Figure 2.0

shows how the 1584-18/18S is assembled. J25 connects DC Power to the fuse as shown and J30 and J29

connect the DC voltage from the power supplies to the PCB as shown.

2.4 Operation

1. Connect RF cables to the 1584-18/18S (See Section 2.2).

2. IF DC VOLTAGE IS REQUIRED ON THE SPLITTER RF INPUT (J17) CENTER CONDUCTOR,

install 1/4”, 0.5 amp fast blo fuses in the FUSE F1 holder

3. Connect 100-240 ± 10% VAC, 47 - 63 Hz to AC A and AC B on the back panel and observe

A and B LEDs are lit on the front panel.*

4. Monitor DC voltage to the external LNB amplifier (Front panel Green ON LED should be lit if

LNB fuse is installed in the rear panel fuse holder) to insure proper voltage.

CAUTION! IF A FUSE IS INSTALLED IN THE FUSE F1 HOLDER, +22 VDC WILL APPEAR

ON THE SPLITTER INPUT CONNECTOR (J17) CENTER PIN.

NOTE: FOR OPTIMUM PERFORMANCE, THE SPLITTER PORTS SHOULD BE TERMINATED

WITH 75 OHM TYPE F TERMINATION WHEN NOT USED.

AC Fuse - The fuse is a 5mm, 2 amp slow blo and is inserted in the far slot in the drawer below the AC

input as shown in Figure 2.6. There is a spare fuse in the near slot. If a fuse continues to open, the power

supply is most likely defective. Note that each power supply module within the chassis also has a fuse

but failure of this fuse indicates the power supply may be defective.

2.5 Environmental Use Information

A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions

located in the user manual furnished by the manufacturer of your equipment rack.

B. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition

does not exist due to uneven weight distribution.

C.Elevated operating ambient temperature - If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack may be greater than room ambient temperature.

Therefore, consideration should be given to Tmra.

D. Reduced air flow - Installation of the equipment in a rack should be such that the amount of air flow

required for safe operation of the equipment is not compromised. Additional space between unit

may be required.

E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply

circuit and the effect that overloading of circuits could have on over current protection and supply wiring.

Appropriate consideration of equipment name plate rating should be used, when addressing this concern.

F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular

attention should be given to supply connections other than direct connection to the Branch

(use of power strips).

G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.

If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED

prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS

emission problems.
