1 Description
1.1 Introduction
ELC serves as an LTC generator with two output stages. The data content within the LTC time
code is either fed from an NTP server or an MTDoE master device. Both LTC output signals are
phase locked to UTC time which is available as well in NTP mode as in MTDoE mode. Time
addresses as well as user data (binary groups) of the LTC can be independently configured
and generated.
These are the key features of ELC:
•PoE power supply.
•Connectors: 1 x RJ45 for Ethernet/PoE, 2 x RJ45 for LTC outputs.
•Set-up and firmware update possible via the “UD SC Config“ program.
•Set-up and status display possible via the integrated Ethernet server.
•All settings will be stored at a non-volatile memory, so the latest set-up will not get lost
if ELC was powered off.
•Frame rate of LTC outputs selectable: 24/25/30/29.97 frames per second.
•LTC signal level adjustable for each output separately.
•Source = NTP:
▪One “Primary“ and one “Secondary“ NTP Server can be addressed.
▪Various date formats can be transported in the binary groups (user data) of the
LTC.
▪Based on UTC received from the NTP Server, ELC can output a time & date LTC of
any time zone, with or without Daylight Saving Time switching.
•Source = MTD:
▪Selectable MTDoE group.
▪Time addresses of LTC can be a local real-time or a time of any MTD counter.
▪A date can be transported in the binary groups (user data) of the LTC.

1.3 Power Supply
ELC receives power via “Power over Ethernet“ (PoE). Power over Ethernet or PoE technology
describes a system to pass electrical power, along with data, on Ethernet cabling. Just connect
ELC to a PoE port of a switch.

PREVENT OVERHEATING
To prevent product overheating, position the unit only where sufficient air
circulation can be maintained. Good air circulation is essential to prevent internal
heat build-up, do not block any ventilation openings. Do not expose the unit to
direct sun light or any other strong lights. Keep the unit away from heat sources.
PROVIDE PROPER ENVIRONMENT
Dust, humidity, shocks and strong electromagnetic fields must be avoided. Do not
expose this unit to dripping or splashing water. Ensure that no objects filled with
liquid are placed on the unit.

2 Firmware Update
Firmware updates require a computer with the UD SC Config program and an Ethernet con-
nection. Computer and ELC have to be connected to the same network. When using a
firewall, either disable it or ensure that the computer can connect to the unit on UDP port
8051 for both incoming and outgoing traffic.
Please have the new firmware (.tcf file) stored on your computer. The latest firmware is
available at:
https://www.plurainc.com.
Execute UD SC Config on your computer. The program gives a list of all MTD devices found
in the network. ELC should be on this list. Access via Ethernet can be protected by a password
(please refer to chapter “System”: View and Change System Parameters).
Select the ELC line, open the File menu, choose Flash Update..., and open the .tcf file.
During the flash update the operation of the device stops!

3.3.4 “Source“: Select the Signal Source
Configuration options (example shows a screen shot of the Ethernet server):
MTD ELC is able to convert data of an MTDoE system to LTC. These data include six
independent programmable timers, real-time, date, and a time of a time code.
Each timer can show a stop timer, a remaining time, a time difference, a time
of a time zone etc.
For a detailed description of the MTDoE system please read the manual The
MTD System –Installation and Operation Manual.
NTP ELC transfers a time & date into LTC. The reference time, received from an NTP
server, can get a programmable offset. It is possible to enable a Daylight-
Saving Time handling.
