Connecting to the Network
Connect one end of the Ethernet cable to one of UC-7408’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, UC-7408
will indicate a valid connection to the Ethernet in the following ways:
The bottom 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.

The bottom 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 UC-7408 to serial devices. UC-7408’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
UC-7408’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 via 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 UC-7408’s serial ports (P1 to P8) via 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 startup via PPP protocol. For details, refer to “Dial-up Service—PPP” section in Chapter 4.
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. Wireless
LAN card expansion is optional. The Wireless LAN card provided by Moxa lets you connect
UC-7408 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.
