Hardware Connection Description
Connecting to a Serial Device
Use properly wired serial cables to connect the DA-661/662/663 to serial devices. The
DA-661/662/663’s serial ports (P1 to P16) use 8-pin RJ45 connectors. The ports can be configured
by software for RS-232, RS-422, or 2-wire RS-485. The pin assignments are shown in the
following table:

Connecting to the Console Port
The DA-661/662/663’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 P16). For normal data acquisition applications,
you should connect to the DA-661/662/663’s serial ports (P1 to P16) 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 start up via PPP protocol.
PCMCIA
The PCMCIA slot supports the CardBus (Card-32) card standard and 16-bit (PCMCIA
2.1/JEIDA4.2) card standard. It su3.3V, +5V, and +12V at a working voltage of 120
mA~1100 mA. The wireless LAN card is optional. The wireless LAN card provided by Moxa lets
you connect the DA-661/662/663 to a wireless LAN. 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
The DA-661/662/663 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.
USB Host
The DA-661/662/663 offers 2 USB 2.0 hosts, allowing you to connect with a USB storage device.
The first USB mass storage device to be connected will be mounted automatically by mount to
/mnt/sda
, and the second device will be mounted automatically to /mnt/sdb. The DA-661/662/663
will be un-mounted automatically with the umount command when the device is disconnected.
