Chapter 1 Product Overview
The DataTronix DT-NTSC-32 takes digital video signals from an IP source, such as a COM3000
or DT-ATSC-IP-8V2 and converts the IP source to analog modulated NTSC TV channels. This
unit can output up to 32 NTSC channels. It solves a common problem for senior living housing
and any other commercial properties that may still have some analog TV's on site, or digital
TV’s not capable of decoding certain video formats. It can receive and decode multiple HD or
SD IP video streams in either MPEG-2, MPEG-4, H.264 or H.265 format. This modulator
supports numerous audio formats that can be decoded and reformatted for NTSC analog
modulated TV channels. This unit is perfect for the following use cases:
Low income properties wanting free off-airTV service in NTSC analog can use the DataTronix
DT-ATSC-IP-8V2 to receive and convert the off-air signals to IP, then use the DT-NTSC-32 to
modulate them onto NTSC analog TV channels.
Properties receiving satellite TV with a DIRECTV COM3000 can connect the DT-NTSC-32 to
modulate 32 satellite channels onto NTSC analog TV channels to support legacy televisions,
gym equipment, or other non-Pro:Idiom displays.
1.1 Key Features
•2 Gigabit Ethernet ports (max 64 IP input over MPTS/SPTS), Max 840Mbps for each
Gigabit Ethernet input
•Supports MPEG-2, MPEG-4, H.264 or H.265 Transport Stream (TS) Decapsulation
•Processing of up to 32 IP multicast groups from a Gigabit Ethernet MPEG TS into up to
32 standard NTSC TV programs.
•Supports Web-based Network management which allows for remote tuning of source
streams and NTSC channel outputs

2.2.2 Environment Requirement
2.2.3 Grounding Requirement
All function modules’ good grounding is the basis of reliability and stability of devices. Also, they
are the most important guarantee of lightning arresting and interference rejection. Therefore, the
system must follow this rule.
Coaxial cables’ outer conductor and isolation layer should keep proper electric conducting with
the metal housing of the device.
Grounding conductors must adopt copper conductors in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.

DT-NTSC-32 Manual
Users should make sure the 2 ends of grounding wire are well electrically conducted and be
anti-rust.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be no less than
4 AWG (25mm2).
Please refer to Article 100 of the NEC for all grounding related items
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strips. The grounding wire
should be as short as possible and avoid circling. The area of the conduction between
grounding wire and grounding strip should be no less than 4 AW G (25mm2).
2.2.5 Device Grounding
Connecting the device’s grounding rod to the frame's grounding pole with copper wire.
2.3 Wire’s Connection
2.3.1 Power cord connection
The power socket is located on the right of the rear panel, as is the power switch. Plug one end
of the power cord to the socket and insert the other end to AC power. When the device solely
connects to protective ground, it should adopt an independent way, say, share the same ground
with other devices. When the device adopts a united way, the grounding resistance should be
smaller than 1Ω.
Caution: Before connecting power cord to DT-NTSC-32, users should set the power
switch to “OFF”.
