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
RF output
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.
Delivery state: 230V~ (Changing to 115V~ see maintenance/change
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.
