Description

General

The Output amplifier OPA 8500 amplifies TV/QAM/FM signals, which are present on the

inputs of the OPA 8500. The OPA 8500 supplies the following coaxial or optical

downstream distribution system with the amplified signals.

The RF-output, RF-inputs and two RF-monitoring outputs operate in the frequency

range 47 ... 862 MHz. The OPA 8500 is built with two parallel hybrids. Two equivalent

mains connections are available via the rear-panel.

The OPA 8500 is used in a combining network. The combining network consists of the

following functional groups:

l

RF-combiner RFC 8500/5

l

RF-combiner RFC 8500/4

l

1 HU Mounting frame MIO 8500 (for maximal 3 RF-combiners)

l

Output amplifier OPA 8500

The OPA 8500 has 10 RF-inputs and one RF-ouptut. The RF-inputs are meant:

l

for TV- or QAM-signals (4 RF-inputs)

l

for FM-signals (4 RF-inputs)

l

for pilot frequency signals or wobbler (2 RF-inputs)

Design

View

The OPA 8500 is built asa1HU19"slide-in module.

The front-panel contains:

l

the display

l

the LED’s

l

the operating elements

l

two RF monitoring outputs

The rear-panel contains:

l

2 x mains connection

l

10 x RF input

l

l

RS232 interface

l

10 Mbit Ethernet-interface

l Remote monitoring interface ”ALARMS”

Cooling The SAI 8500 is cooled by convection.

Power supply

The OPA 8500 can be operated with the following mains voltages:

l

115 VAC

l

230 VAC

The power supply is of redundant design. For back-up purposes there are two mains

connectors available on the rear-panel. The OPA 8500 can be integrated into a back-up

supply system.

ATTENTION: Before operation make sure that the mains voltage matches the

supply voltage indicated on the device.

The mains fuse is located beside the mains socket. The OPA 8500 does not have a

mains switch. To disconnect the OPA 8500 from the mains, both mains plugs must be

pulled out of the device. Both mains voltages (mains 1, mains 2) can be monitored

through alarm messages.

Control

General For controlling there are the following possibilities:

l

Keypad and display on the OPA 8500 (see chapter ”Menu operation”)

l

10 Mbit Ethernet-interface (Software option “Network Access Control”)

l

RS 232 Interface for stand-alone devices (Software option “Network Access

Control*)

Remote control in a

network

(software option)

The OPA 8500 can be remote controlled via the Ethernet interface or RS232 interface.

A standard WWW-browser with TCP/IP protocol (e.g. Internet Explorer) is to be used.

The remote control can be disabled on the OPA 8500.

Monitoring

General For monitoring there are the following possibilities:

l

keypad and display

l

LED’s “ f ” and “OUT” (see interfaces and operating elements)

l

Monitoring outputs “RF m”

l

10 Mbit Ethernet-interface (Software option “Network Access Control”)

l

RS 232 interface for stand-alone devices (Software option “Network Access

Control”)

l

Remote monitoring interface ”ALARMS”

l

History / operation log (see menu operation)

l Status display (see menu operation)

Remote monitoring

interface ”ALARMS”

On the remote monitoring interface ”ALARMS” the status messages ”ALARM” and

”WARNING” are signalled via two floating double-throw contacts.

To the floating double-throw contacts external error indicators ( e.g. siren, lamp) can be

connected. The pin-assignment is shown in the section ”Interfaces and operating

elements”.

RF combiner

With the passive and broadband RF-combiners the RF signals can be combined int eh

frequency range from 47 MHz up to 862 MHz.

There are following types of RF-combiners:

l

RF combiner RFC 8500/4 four inputs, one output

l

RF-combiner RFC 8500/5 five inputs, one output

The RF-combiners are mounted in the mounting frame MIO 8500. The MIO 8500

measures 1 HU and 19”. It can contain up to three RF-combiners.

Start-up

ATTENTION: Operating work must be carried out by staff with RF-knowledge.

ATTENTION: If the device is steamed up after unpacking, it must be acclimatized

at least one hour before starting operation.

ATTENTION: During operation the vents must not be covered. When mounting

the device in a rack take care that there is a gap of at least 1HU

between the devices.

NOTE: When building in the device in a rack use rails or any other suitable

mount.

NOTE: Before operation read the chapter ”Menu operation”.

Procedure

1. Check if the supply voltage shown beside the mains socket matches the mains

voltage.

ACHTUNG: A wrong mains voltage may cause a defect in the device.

Therefore check the mains voltage before connecting the module to

the mains.

of the mains voltage)

2. Slide in the OPA 8500 into the intended place in the 19" rack.

3. Fix the module with the 4 screws on the front-panel.

4. Connect the signal cabling.

5. Connect the OPA 8500 to the mains ( boot procedure starts).

6. Adjust the contrast of the LC-display (see menu operation ”display / contrast”)

7. Check the LED´s on the front-panel.

l

LED “ f ” does not light up

l

LED “OUT” lights up

8. Set the desired warning- and alarm thresholds for the displayed values.
