NT-52P – Getting Started 3
3 Overview
The NT-52P is a compact universal−I/O PoE control gateway, capable of plug and
play deployment over an existing LAN for remote control of customer−controlled
devices via two universal I/O ports. The ports can be configured as bidirectional
RS−232, crossed RS−232, RS−485, IR, GPI/O or relay control connections.
Multiple control clients can be connected over IP to the NT-52P control gateway for
concurrent control of devices, such as AV scalers, video projectors and displays,
audio amplifiers, DVD players, sensors, screens, shades, door locks, and lighting.
The NT-52P features:
• Innovative Universal I/O Ports – Remote IP-based control of any device
connected to the control gateway universal I/O ports, with selectable port
configuration to bidirectional RS−232, RS−232 cross, RS−485, IR, GPI/O or
relay control. Each port is adaptable for any room device control simply by
toggling a button.
• Multiple IP Connected Clients – Remotely connected over an existing
Ethernet network, concurrently controlling any devices connected to control
gateway universal I/O ports.
• Easy & Reliable Installation:
• Plug-and-Play IP Installation with dynamic (DHCP) address resolution
and auto device discovery over existing LAN.
• Compact, designed for piggy−back installation, such as behind a TV or
display, with the ability to draw power over Ethernet.
• Remote Management:
• Single PoE cable for both, powering and connectivity, and Plug and
Play IP installation with dynamic (DHCP) address resolution and auto
device discovery over existing LAN.
• Highly−resilient powering with multiple power options — Power over
Ethernet per IEEE 802.3af standard, and/or PSU (included).
4 NT-52P - Overview
• Built−in web UI for remote browser−based management and support,
by multiple IP−clients over existing LAN.
• Easy firmware upgrades, either remotely via existing LAN, or locally via
USB device port.
• Size – DigiTOOLS™ – Mount 3 units side-by-side in a 1U rack space with the
optional RK−3T rack adapter.

, set and save RS-232 to Mode 1.
•
6. If the NT-52P does not receive power from a PoE provider, connect the
device to the power supply and connect the power adapter to the mains
electricity (as shown in Figure 4
Changing the port mode resets the ports to their default state: GPIO
goes to its low state and the relay goes to its open state.
Save Settings Procedure:
• Press to cycle through and select a Port 1 or 2 mode function.
See Table 1
for selected mode button color.
• Wait approximately 5 seconds until ‘Save?’ appears on LCD display
