10 Hardware Configuration
RX2 Reference Guide E-EQ-RX2RG-B
Central Processing Unit
The CPU is an Intel
®
Xscale
®
PXA255 running at 400 MHz.
System Memory
A CF Card FLASH is used for ROM, Flash for Windows CE .NET and Flash memory for bundled
applications. The Flash is configured as the primary boot device and contains the Windows CE
.NET image, boot loader, OAL, applications, utilities and device drivers.
Any flash remaining beyond the Windows CE .NET image is formatted for use as a persistent
memory drive (which appears in My Computer as the folder “System”). Any programs or data
stored in this folder will be preserved if the power fails or the RX2 is coldbooted.
There are no user accessible CF slots.
Core Logic
The mobile device supports the following I/O components of the core logic:
• One PCMCIA slot (supports Type I or II PCMCIA cards), used for 2.4GHz radio.
• Two external I/O ports:
o D9 for USB client adapter cable (USB-C).
o D9 for COM3 (COM3/RS-232).
• One internal I/O port used for RFID reader.
Video Subsystem
The RX2 does not support a display. However, the RX2’s desktop can be viewed using an
ActiveSync connection and ActiveSync Remote Display.
Power Supply
The RX2 has an optional battery.
• A 4000 mAh internal NiMH battery is optional when ordering the RX2. The internal
battery must be charged using the RX2 charger. This battery powers the RX2 for a
minimum of 9 hours and recharges in less than 6 hours.
The RX2 can also be connected to a DC power source.
• A direct connection is supported for 12VDC powered vehicles.
• A DC to DC adapter is available for vehicles with 24 to 60 VDC power.
See “Power Supply Options”, later in this chapter, for more details.
PCMCIA Slot
The mobile device has one internal PCMCIA slot that conforms electrically to PCMCIA 2.0.1
specifications. The PC Slot supplies 0.75 of an amp at 5Volts or 3.3Volts. Battery voltage is
supplied through unused pin 35 to support a WAN radio in the slot.
The PC slot is not accessible to the user. A Summit 2.4GHz 802.11b/g or Cisco 2.4GHz 802.11b
radio is installed in this slot when the RX2 is assembled by LXE.
