UNO-420 Interface

The UNO-420 PoE Powered Device Sensing Gateway with 3 x COM, 2 x LAN (1 x
PoE), 8 x Programmable GPIO, HDMI, USB3.0.
2.2.1

LAN: Ethernet Connector

UNO-420 is equipped with two Gigabit LAN controller. For the UNO-420, the control-
ler chip used is an Realtek RTL8119E Ethernet controller that is fully compliant with
IEEE 802.3u 10/100/1000 Base-T. The Ethernet port is a standard RJ-45 jack, and
there is one support PoE-IN IEEE 802.3at. LED indicators are on the front to show its
Link (Green LED) and Active (Green LED) status.
2.2.2

COM Port Interface (COM1, COM2, COM3)

COM1 (RS-232/422/485) DB9, 50~115.2kbps
COM2 (RS-232/422/485) DB9, 50~115.2kbps
COM3 (RS-485) Terminal block, 50~115.2kbps
2.2.3

GPIO Connector

GPIO0 to the GPIO7 pins are 0-5 V input/output and digital/analog configurable pins.
Note! The GPIO port is powered by analog devices' AD5593R.
Each pin has a 100K OHM series resistor between the connector and
the AD5593R.
Caution! This port is ESD-sensitive. An insulated GPIO connector that prevents
direct ESD exposure to the I/O pins is recommended.
2.2.4

Power Connector

UNO-420 comes with a Phoenix connector 10~30Vdc or RJ-45 PoE-In IEEE 802.3at
Compliant (Type 2) PD (42.4~57.0 V) external power input and features reversed wir-
ing protection. Therefore, it will not cause any damage to the system by reversed wir-
ing of ground line and power line.
2.2.5

USB Connector

The USB interface supports Plug and Play, which enables you to connect or discon-
nect a device whenever you want, without turning off the computer. The UNO-420
provides one USB 3.0 connector.
2.2.6

RTC Battery Specification

The UNO-420 has an RTC Battery to ensure the setting in BIOS and system clock
can be kept, even with power disconnected for a short time.
