Introduction

Connecting to a Serial Device

Use properly wired serial cables to connect UC-7420/7410 to serial devices. UC-7420/7410’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:

Connecting to the Console Port

UC-7420/7410’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-7420/7410’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-7420/7410 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.

CompactFlash

UC-7420 provides one CompactFlash slot that supports CompactFlash type I/II card expansion. Currently, Moxa provides a CompactFlash disk for plug & play mass storage expansion. You may also use flash disks available from most computer supply outlets. The CompactFlash will be mounted at /mnt/hda

If you need device drivers for other kinds of mass storage cards, contact Moxa for information on how to initiate a cooperative development project.
