MAR-2002-T
DI, DO
The MAR-2000 has 4 digital output channels and 4 digital input
channels. The MAR-2000 Hardware User’s Manual has detailed
pinout and wiring diagrams.
Reset Button
Press and hold the
Reset
button continuously for at least 5
seconds to reload the factory default configuration. After the
factory default configuration has been loaded, the system will
reboot automatically. The Ready LED maintains a steady glow once
the system has rebooted.
CompactFlash
The MAR-2000 has a single CompactFlash type I/II slot for
memory expansion. The CF card can be accessed by unscrewing
the panel located on the bottom of the MAR-2000.
The mount point for the CompactFlash filesystem is /dev/sda.
WARNING
Be sure to power off the computer before inserting or
removing the CompactFlash card.
Console Port
The RS-232 console port is a 4-pin header connector located on the
underside of the motherboard above the CF card socket. As above,
use a screwdriver to remove the panel protecting the CF card to
access the 4-pin RS-232 connector. This serial port is used to
access the console terminal, and is useful for viewing boot
messages, file system logs, and error messages. Use the
CBL-4PINDB9F-100 cable included with the MAR-2000 to connect
a PC to the MAR-2000’s serial console port.
USB
The MAR-2000 computer features 2 USB 2.0 ports for external
storage expansion.
Powering on the MAR-2000
To power on the MAR-2000, connect the power cable to the M12
connector and then connect the power adapter.
ATTENTION
The
shielded ground
should be connected to the center
pin of the power input connector.
Note that it takes approximately five minutes for the system to get
ready. Once the system is ready, the
Ready
LED will light up.
Connecting to the MAR-2000
There are three ways to connect the MAR-2000 to a PC: through
the MAR-2000 management web page, the serial console port, or
by SSH over the network. The COM settings for the serial console
port are:
Baudrate=115200 bps
,
Parity=None
,
Data bits=8
,
Stop bits =1
,
Flow Control=None
.
ATTENTION
Remember to choose the
VT100
terminal type. To connect
a PC to the serial console, use the CBL-4PINDB9F-100
cable that shipped with your MAR-2000.
To use SSH and the MAR-2000 management web page, you will
need to know the MAR-2000’s IP address and netmask. The default
LAN settings are shown below. For initial configuration, you may
find it convenient to use a crossover Ethernet cable to connect
directly from the PC to the MAR-2000.
Default IP Address

192.168.3.127
255.255.255.0
LAN 2
