UC-7400 Plus User’s Manual Hardware Connection Description
Connecting to the Network
Connect one end of the Ethernet cable to one of the UC-7400 Plus’s 10/100M Ethernet ports (8-pin
RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected,
the UC-7400 Plus will indicate a valid connection to the Ethernet in the following ways:
18
The lower right corner LED indicator maintains a solid
green color when the cable is properly connected to a
100 Mbps Ethernet network. The LED will flash on and
off when Ethernet packets are being transmitted or
received.
18
The lower left corner LED indicator maintains a solid
orange color when the cable is properly connected to a
10 Mbps Ethernet network. The LED will flash on and
off when Ethernet packets are being transmitted or
received.

Connecting to a Serial Device
Use properly wired serial cables to connect the UC-7408 Plus, UC-7410 Plus, and UC-7420 Plus
to serial devices. The UC-7408 Plus, UC-7410 Plus, and UC-7420 Plus’s serial ports (P1 to P8)
use 8-pin RJ45 connectors. The ports can be configured by software for RS-232, RS-422, or
2-wire RS-485. The precise pin assignments are shown in the following table:

2 RTS TXD+ ---
3 GND GND GND
4 TXD TXD- ---

Connecting to the Console Port
The UC-7400 Plus’s console port is an 8-pin RJ45 RS-232 port. The port can be used to connect to
the console utility from a remote console through a V90 or GPRS modem with PPP protocol. The
pin definition is the same as for the serial ports (P1 to P8). For normal data acquisition applications,
you should connect to the UC-7400 Plus’s serial ports (P1 to P8) through a V90 or GPRS modem.
If you would like to use the console port for normal data acquisition applications, you can set the
console port to start up with PPP protocol.
PCMCIA
The PCMCIA slot supports the CardBus (Card-32) Card standard and 16-bit (PCMCIA 2.1/JEIDA
4.2) Card standard. It supports +3.3V, +5V, and +12V at a working voltage of 120 mA~1100 mA.
The wireless LAN card expansion is optional. The wireless LAN card provided by Moxa lets you
connect the UC-7400 Plus to a wireless LAN, with both 802.1b and 802.11g interfaces supported.
If you need device drivers for other kinds of PCMCIA cards, contact Moxa for information on how
to initiate a cooperative development project.
