CFast Slot
The V2426A has 2 CFast sockets. One slot is located on the front
panel for OS storage and the other slot is located inside the
V2426A for backup storage. Both slots support CFast Type-I/II
with DMA mode.
To install an OS CFast card, remove the outer cover and insert the
CFast card in the socket. When finished, push the cover into the
socket and refasten the screws.
To install a CFast card for backup storage, purchase a CFast card
through Moxa’s CTO* service. Refer to the V2426A datasheet for
more information.

USB Hosts
The V2426A has one USB port with an M12 D-coded connector on
the front panel, and two USB ports with type A connectors on the
rear panel. These USB ports can be used to connect flash disks for
storing large amounts of data.
SATA Connector
The V2426A has 1 SATA-I/II connector for 2.5" SSD/HDD storage
expansion. To expand storage capacity, purchase an SSD/HDD and
an internal storage kit* through Moxa’s CTO** service.
*This must be purchased separately to install an SSD / HDD. For
details, check the optional accessories section of the V2426A
datasheet.

Expansion Slots
The V2426A computers come with two expansion slots that
supports different communication modules (for example, 2-port
CAN module, or HSDPA, GPS, or WLAN module) to provide
additional flexibility.
To remove an expansion module, first turn off the V2426A and
remove the screws that secure the expansion module to the chassis;
then, pull to remove the expansion module from the V2426A.
Ethernet Ports
Two 10/100/1000 Mbps Ethernet ports
using M12 X-coded connectors are
located on the front panel. The pin
assignments are shown in the figure.
Serial Ports
The serial ports use DB9 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.

Reset Button
Press the “Reset Button” on the rear panel of the computer to
reboot the system. The Ready LED blinks for the first 5 seconds,
and then turns steady on after the system has rebooted
successfully.
Real-Time Clock (RTC)
The V2426A’s real-time clock is powered by a lithium battery. You
can easily replace the battery yourself using an optional battery
kit*. However, please note that there is a risk of explosion if the
battery is replaced by an incorrect type of battery. Refer to the
V2426A Hardware User's Manual or contact a qualified Moxa
support engineer if you have any questions about the RTC battery.
*Moxa offers an “RTC battery kit” that you can use to easily replace
the battery. For details, check the optional accessories section of
the V2426A datasheet.
Powering on the V2426A
To power on the V2426A, connect the power cable to the V2426A’s
M12 A-coded power connector (located on the rear panel). Press
the power button to turn on the computer. Note that the Shielded
Ground wire should be connected to the central pin of the
connector. It takes about 30 seconds for the system to boot up.
Once the system is ready, the Power LED will light up.
