Serial Ports
The four serial ports (P1 to P4) use RJ45 connectors. Each port can
be configured by software for RS-232, RS-422, or RS-485. The pin
assignments for the ports are shown in the following table:

SD Interface
The IA240 comes with an SD socket for storage expansion. Moxa
provides an SD flash disk for plug & play expansion. The disk
allows users to plug in a Secure Digital (SD) memory card
compliant with the SD 1.0 standard for up to 1 GB of additional
memory space, or a Secure Digital High Capacity (SDHC) memory
card compliant with the SD 2.0 standard for up to 16 GB of
additional memory space. The SD socket is located at the front side
of the IA240. To install an SD card, you must first remove the SD
protection cover to access the socket, and then plug the SD card
into the socket directly. Remember to push in on the SD card first
if you want to remove the card.
The SD card will be mounted at
/mnt/sd.
Console Port
The console port is an RJ45 RS-232 port. It is designed for serial
console, and can be connected to a V90 or GPRS modem via PPP.
The pin definitions are the same as for the four serial ports (P1 to
P4).
Reset to default Button
Press the “Reset to Default” button continuously for at least 5
seconds to load the factory default configuration. After the factory
default configuration has been loaded, the system will reboot
automatically. The Ready LED will blink on and off for the first 5
seconds, and then maintain a steady glow once the system has
rebooted.
Reset Button
Press the “Reset” button to activate the hardware reset function.
You should only use this function if the software does not function
properly. To reset a Linux system, you should reboot the operating
system to avoid deleting important data.
USB
The USB 2.0 Host port now supports a USB storage device driver.
The USB storage will be mounted at
/mnt/usbstorage.
Real Time Clock
The IA240’s real time clock is powered by a lithium battery. We
strongly recommend that you do not replace the lithium battery
without help from a qualified Moxa support engineer. If you need
to change the battery, contact the Moxa RMA service team.
ATTENTION
There is
a risk
of explosion if the battery is replaced by an
incorrect type of battery.
6. Powering on the IA240
To power on the IA240, connect the “terminal block to power jack
converter” to the IA240’s DC terminal block (located on the left
rear panel), and then connect the power adaptor. Note that the
Shielded Ground wire should be connected to the right most pin of
the terminal block. It takes about 30 seconds for the system to
boot up. Once the system is ready, the Ready LED will light up.
7. Connecting the IA240 to a PC
There are two ways to connect the IA240 to a PC: (1) through the
serial console port, or (2) by Telnet 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. Use the
CBL
-RJ45F9-150 cable included with the product to
connect a PC to the IA240’s serial console port.
To use Telnet, you will need to know the IA240’s IP address and
netmask. The default LAN settings are shown below. For first-time
configuration, you may find it convenient to use a cross-over
Ethernet cable to connect directly from the PC to the IA240.
Default IP Address
Netmask
LAN 1
192.168.3.127
255.255.255.0
LAN 2
192.168.4.127
255.255.255.0
Once the IA240 is powered on, the Ready LED will light up, and a
login page will open. Use the following default Login name and
Password to proceed. The defaults are:
Login: root
Password: root
8. Configuring the Ethernet Interface
If you use the console cable for first-time configuration of the
Network settings, use the following commands to edit the
interfaces file:
#ifdown –a
//Disable LAN1/LAN2 interface first, before you
reconfigure the LAN settings. LAN 1 = ixp0, LAN 2=
ixp1//
#vi /etc/network/interfaces
//check the LAN interface first//
After the boot setting of the LAN interface has been modified, use
the following commands to activate the LAN settings immediately:
#sync ; ifup –a
NOTE
Refer to the IA240 User’s Manual for other configuration
information.
