IPQAM-801 DVB-C A/C Modulator IP to QAM User Manual
Chapter 1 Introduction
1.1 Product Overview
A compact agile DVB-C A/C QAM channel modulator with integrated multiplexer receiving UDP
multicast streams in any Codec/Resolution incl. SD, HD, 4K UHD compatible with h.265, h.264
& MPEG2 codec from multiple Encoder- & DVB IP streamer sources. DVB-C QAM Modulator as
addon Channel to existing CATV networks or serving Information-Channels or Digital Signage
by Cable-TV. UHD h.265 (HEVC) -, h.264 compatible in Distribution of SD, HD and UHD TV
channels through the existing CATV Coax network using state-of-art IP to QAM technology from
almost any kind of video format input streams.
TV distributions in home entertainment, surveillance control, hotels, digital signage, shops,
bars, etc. excellent Video and Audio quality. High reliability. No regular service and
maintenance need during operation.

16, 32, 64, 128, 256QAM modulation modes
Configuration by SNMP based MS-Windows-Tool (remote setup possible)
We assume that the user is familiar with IP settings and already knows his own system to connect the unit to.
If you use the Output Streaming feature: We recommend using 2 separate Switches! At least a 100BaseT for
the Management NMS RJ45 port and/or a second one with Gigabit Ethernet 10/100/1000BaseT with at least
Layer 2+ with IGMP V2 features. Otherwise you might flood your network with unnecessary IP-Streaming
Data, which might overload connected devices. If you need to select a Switch, we recommend ARUBA HP
Procurve 2530 24G or 48G which are cost effective, easy to configure, can be trunked and supporting IGMP
V2. For this model it's better to check the Firmware version because sometimes the newest one has IGMP
problems.
If the switch needs routing functions, the bigger brother of this series might be the right choice.
Because to not accidently put DATA and NMS port in the same sub-network the data – port setting does not
allow this by default. Usually the DATA GbE Port needs an IP address- otherwise the Switch or the receivers
(i.e. IPTV STB's) cannot locate the source of the streams.
