4. Troubleshooting FAQ
4.1. EPoC transmission equipment
Problem
What is EPoC?
What is the basic configuration?
What are the basic things to
check during the initial
installation?
Does the initial installation require a
device setup?
The connector of the 48-57 VDC
Adaptor purchased is not connected
to the DC IN terminal of the EPoC.
Tx, Rx EPoC 1 Set (2 ea) was
purchased. Should 48-57 VDC
Adaptor be installed on each Tx,
Rx EPoC?
Looking at the features,
First, when replacing analog cameras with high-resolution IP camera, you can
use the existing Coaxial cable without any special construction.
Second, you can supply PoE power or 12VDC to IP camera. As a result, there is
no additional power wiring work when installing IP cameras.
Third, it is possible to send signals over long distance by modulating and
demodulating digital signals into RF signals.
Fourth, you can apply transmission media that is suitable for your installation.
There are various types of transmission media, such as Coaxial, 2-wire and an
additional cable exchanger (BTE-04) is applicable.
Fifth, while the existing analog camera has the installation distance limitation,
EPoC is applied to IP camera and can be installed up to several hundred
meters away. Please refer to the installation distance for each product and
transmission medium.
NVR ↔ Rx EPoC(ADC) ↔ Tx EPoC (DAC) ↔ IP camera are configured as one
set. Therefore you need two EoCs (Tx, Rx) and adapter per IP camera.
You need to check
- the transmission media (Coaxial, Twisted pair)
- the installation distance, - the rate of 48~57 VDC power adapter,
- the LED states of the device when applying power to the device.
You also need to check the operating environmental
temperature/humidity and grounding.
Because of working Plug & Play method, any setting is not required, but it
depends on the situation. In a suspected interference environment
between lines, group joining of the device helps avoid cross-talking by
changing passwords between groups.
EPoC DC IN connector is different from the connector size of
48VDC Adapter.
Please note that the inner pin spec of DC IN connector is 2.18 mm.
