ET1100C2 Series
Industrial 10/100Base-TX Ethernet plus CVBS Over Coax Converter
This quick start guide describes how to install and use the Industrial Coaxial Converter. This is the Coaxial Converter
of choice for harsh environments constrained by space.
Overview
ET1100C2 is a pair of 10/100Base-TX Ethernet plus CVBS (composite video baseband signal) over coax converters.
It completely complies with the international standards such as IEEE 802.3 10Base-T, IEEE802.3u 100Base-TX,
and IEEE 802.3X.
The product series consists of a transmitter (ET1100C2-T) and receiver (ET1100C2-R). The maximum transmission
distance of a coaxial cable is 300m. The ET1100C2 series products can transmit not only the existing CVBS over the
coaxial cable, but also the IP signals of network products (e.g. IP cameras) at the same time. With ET1100C2 series
products, it is a cost effective way to upgrade the analogue video surveillance system to workable with the IP
cameras to the video surveillance system without laying the cable again.
General
To ensure trouble free transportation and storage, all OT Systems products must be thoroughly inspected, tested
and properly packed before delivery. Check the product upon receipt for any visible damage which may have been
caused during shipment.

Installation Steps
a) Connect the COAX DATA connector of the transmitter (TX) and receiver (RX) with coaxial cable.
b) At TX side, connect the analogue camera video signal to the CVBS INPUT connector with coaxial cable, the IP
camera signal to the Ethernet port (10/100) with network cable.
c) At RX side, connect the monitor to the CVBS OUTPUT with the coaxial cable, the NVR/switch to the Ethernet
port (10/100) with network cables to the switch or PC.
d) The PWR light is on when the product is powered on. Check if the power cable is working properly.
e) After all cables are correctly connected, the indicators will be lit as per port status LEDs (page 3).

Assembly, Startup, and Dismantling
Installation
Installation: Mount the Micro type unit onto a fixture, or camera housings, e.g. a plank, (either on the wall or on
a flat surface) with at least 2 screws piercing through the holes on the mounting frame to secure it in position.
Startup: Connect the supply voltage to start up the Media Converter via the terminal block.
Dismantling: Locate and remove the securing screws. Usually, but not limited to, at least 2 screws.
