3. Connector Description
The SB-X270 uses the attached CM-X270 module to implement most of the provided
functions. For these functions, the SB-X270 routes the signals from the CM-X270’s
miniature connectors to the standard connectors. The function’s description is therefore
provided in the CM-X270 Reference Guide. The section below provides only the
description of the external interface connectors. The subsequent section provides the
specifications of those functions implemented on the SB-X270 itself.
3.1. COM-A Connector on Front Panel (P27)
RJ-11 6-pin connector, compatible with a standard RJ11 / DB9 cable (available from
CompuLab). RS-232 level Rx/Tx/RTS/CTS are provided, other modem control lines are
not available. This connector is available only with the front panel option.

Notes
• An LCD power supply voltage selection jumper must be assembled in either 1-2 or 2-3
position for normal LCD functionality.
• A jumper must be assembled on pins 10-11 to provide power, if USB3 is used in host
mode. A jumper must be removed when USB3 is used in slave mode. Jumper only
selects power; the switching between host and slave modes is controlled by ARMmon
command.
• If card includes “F” (front panel) option, then USB1 is routed to the front panel rather
than to P15 header. To change this assignment, user must remove RN40 bypass and
solder it in RN38 location. In cards without “F” option, this is a default assignment.
• USB4 port is available only with CM-X270W module.

Notes
• Pull pins 5 & 7 low to write protect CoM’s NAND and NOR flashes respectively. For
this purpose jumpers can be assembled on P14 5-6 and/or P14 7-8.
• MIC-IN and IN-L signals are connected together; consequently, microphone recording
and line recording can’t be done simultaneously.
• In early versions of SB-X270 there are 4 capacitors assembled, which sometimes
affect touchscreen operation. If you are facing touchscreen problems, please remove
C140, C143, C150, C151. For capacitors location refer to [Developer] >> [X270] >>

3.8. PCMCIA Power Header (E4)
This header selects the VCC voltage for PCMCIA / CompactFlash cards in the PCMCIA
slot. The SB-X270 does not support automatic voltage selection, so the user is responsible
for setting the correct VCC voltage before inserting the card, by shorting the appropriate
pins on E4. For 5V supply, short pins 1-2 and for 3.3V supply short pints 2-3. VPP is
constant at 5V.

3.9. CardBus Slot (P7)
68-pin PC Card / CardBus slot including card guides.
The SB-X270 implements a simplified CardBus interface, which connects the CardBus
socket directly to the PCI bus of CM-X270. The provided CardBus implementation doesn't
support hot plug, thus the card has to be inserted before powering the system. The
enumeration sequence is performed using on-board glue logic which controls the CBFRAME# signal by software.

Signals marked in gray are not supported. In general, functionality of the PC104 bus of the
SB-X270 has the following limitations:
DMA channels are not supported.
Only four interrupt inputs are supported. B23, B25, D04, D06 pins are consolidated to
GPIRQ1 through OR gate.
Some signals of secondary importance are not supported: MEMSC16, IOCS16#,
BALE. The irrelevant signal REFRESH is also not supported.
Signals marked with (*) are generated by on-board logic. See section 4.3 for details.
The PXA-270 CPU does not support 8-bit granularity accesses. In order to make
attaching 8-bit PC-104 cards to the SB-X270 possible, LB-A21 was connected to SA0.

4. Functions Implemented on the SB-X270
Most of the functions are implemented by the attached CM-X270 module, while the SBX270 board provides connectors or headers. Several additional functions are implemented
on the SB-X270 itself and are described in this section.
Note: The SB-X270 uses a CPLD (programmable logic IC) in order to implement
combinatory logic functionality. This is done in order to reduce component count and add
some flexibility to the design. The usage of a CPLD is not obligatory and can be replaced
by discrete logic IC’s. The internal design description of the CPLD is attached to the SBX270 schematics package.
4.1. PC/104 and IDE addressing and logic
The SB-X270 implements address decoding logic by GPCS and IDE-CS signals from the
CM-X270 for driving a number of control signals (OE#, WE#, CS#) to the PC/104 and
IDE buses. Below is a memory address map for the above buses and relevant active control
signals:
Description Address range Active control signals

0x0C000000-0x0CFFFFFF ISA-RD#, ISA-WR#
PC/104 IO access
region
0x0D000000-0x0DFFFFFF ISA-IOR#, ISA-IOW#
IDE CS1 region 0x0E000000-0x0EFFFFFF IDE-CS#1, IDE-RD#, IDE-WR#
IDE CS0 region 0x0F000000-0x0FFFFFFF IDE-CS#0, IDE-RD#, IDE-WR#
4.2. PC-Card CardBus socket
The SB-X270 implements a custom solution allowing usage of standard 32bit CardBus
cards without a need for dedicated CardBus controller.
The cards are connected directly to the PCI bus and dedicated logic blocks the CBFRAME# signal during irrelevant PCI configuration cycles. The O/S drivers have been
slightly modified but, in general, the solution acts as a standard CardBus interface. The
CARDBUS-CTL signal is used to control the CB-FRAME# blocking. Please refer to the
SB-X270 schematics for implementation details. Only 3.3V PC-Cards are supported.
NOTE: this solution does not allow card insertion/removal (hot-plug) while the system is
powered.

4.3. 10/100 Mbit Ethernet Port
The SB-X270 contains one optional 100 Mbit Ethernet port. This is in addition to the
optional Ethernet port contained in the CM-X270. The user can therefore order the CMX270 / SB-X270 combination with none, one or two Ethernet port(s). The Ethernet
interface is based on the Realtek RTL8139 chip.
The Ethernet port’s interface is either through the standard RJ45 connector on the front
panel or through 20-pin FPC connector P31. If the P31 interface used, the appropriate
FPC cable and RJ-45 module can be obtained from CompuLab.
4.4. RS-232 and RS-422/485 Serial Port Drivers
The CM-X270 module has on-board RS-232 drivers for the COM-A port. Other serial
ports of the CM-X270 have TTL level interfaces. The SB-X270 adds several driver options
for some of the serial ports as specified in the table below. Driver support includes modem
control lines.

Notes
COM-D is shared with the IR port.
If the SB-X270 is assembled with no drivers for a particular COM port, then the port
signals are available with TTL levels (except for COM-A).
The interface of the COM-C port can be either RS-232 or RS-422/485 or both,
controlled by assembling the appropriate driver chips. Assembling is done according to
the SB-X270's configuration code: [none] - drivers not assembled, "Y2" - only RS-232
drivers assembled, "Y4" - only RS422/485 drivers assembled, "Y6" - both RS-232 and
RS-422/485 drivers assembled.

The SB-X270 contains RS-422/485 drivers if its configuration code has the "Y4" or "Y6"
option. In the case of "Y6" option, when both RS-232 and RS422/485 drivers are present,
the SB-X270 will automatically switch into RS-232 mode on the presence of valid voltage
levels on RS-232 RX input. In the absence of valid input, the card will switch to RS422/485 mode.
In RS-422/485 modes, TXD outputs of the COM-C port are enabled by the RTS2 signal.
RTS "1" level enables TX output, RTS "0" disables it.
In RS-485 (half duplex) mode, transmit and receive operations are performed on TX lines.
To achieve this, the user must physically connect the RX and TX lines of the serial driver,
i.e., RX+ to TX+ and RX- to TX-. In this case, the selection between receive and transmit
operations is performed by RTS.
In RS-422 (full duplex) mode, transmit and receive operations are performed on separate
line pairs. TX output can always be enabled, though qualifying it by RTS has no practical
effect on system operation. RX and TX lines should not be connected together as in the
case of RS-485.
For a better understanding of RS-422/485 driver operation, please refer to the SB-X270
design schematics, available following the [developer] >> [X270] links in CompuLab's
web-site.
4.5. LCD Power Switch and VDD selection
The graphics controller for TFT panels is located on the CM-X270 module. The SB-X270
adds the power switch required for certain LCD panels.
Many LCD panels require proper power sequencing in order to avoid panel damage. The
graphics controller of the CM-X270 module provides the LCD-ENVDD signal, which can
be used to indicate when power should be applied. The LCD-ENVDD signal is AND'ed
with the system’s RESET-OUT# signal. The LCD power switch circuit on the SB-X270
applies a VDD on the LCD interface connector under the control of ENVDD and RESETOUT# .
LCD Supply selection: the user can select 3.3V or 5V supply by a jumper on the P15
header, pins 1-2 for 3.3V or 2-3 for 5V.
Note: although it is possible to supply 5V to the LCD, the CM-X270 supplies LCD signals
at a 3.3V level. The LCD should be compatible with these levels in order to operate
properly.

4.6. Power Supply Options
Supply voltage options are:
1. 5V only
In this case, 3.3V is generated on-board, by a step-down converter.
Note: additional cards, like PC/104+ or PCMCIA should not draw more than 3A from
3.3V.
2. 3.3V and 5.0V
3.3V and 5V can be supplied via the power connectors or PC/104+ connector.
3. 12V-48V input
The "S48" option allows the assembly of a versatile step-down switching converter. It
permits unregulated DC input in the range of 12V-48V and delivers a regulated 5V
supply to the system. Connector P28 should be used for high-voltage DC input.
GSM / GPRS supply
CM-X270W modules featuring the GSM / GPRS (K) option require 3.6V voltage for
proper operation. Replace R55 shown below with a 20k resistor to provide 3.6V to the
CM-X270. Cards are shipped by default voltage supply set to 3.3V rather than to 3.6V.
Without R55 modification, GSM / GPRS option would not work.

4.7. CRT Interface - Video DAC
The SB-X270 implements an interface to CRT monitor by Video DAC, which converts
digital data of CM-X270's TFT output to analog RGB signals. Horizontal and vertical
synchronization signals are also generated from the TFT interface. All CRT interface
signals are routed to CRT connector P24 and FPC connector P31 as described in chapter 3.
4.8. Front Panel
The unique mechanical design of the SB-X270 allows selecting between two popular form
factors – either a standard PC/104+ with headers or an extended PC/104+ with front panel
connectors.
The SB-X270 printed circuit board has an extension used for the assembling of standard
connectors - two Ethernet ports, serial port, two USB ports and CRT monitor. If a front
panel is not required, this extension can be removed, either before assembling or even on
an already assembled card. If the front panel is removed, the SB-X270 remains fully
functional while the functions of front panel connectors are available through FPC
connectors P31 and P11.
Instructions for front panel removal
If you have the board with front panel and you need to remove it, follow these steps:
1. The board has the v-groove cut lines along the front panel, on the both sides of PCB.
Deepen these cut lines using sharp knife. Exert significant pressure. Be careful not to
hurt yourself !
2. Fix the front panel (the part to be removed) in carpentry vice.
3. Gently push the board backward and forward until it breaks along the cut line.
Note: trace wiring inside the PCB are designed to support this method of front panel
removal.

6. Operating Temperature Ranges
The SB-X270 is available with three options of operating temperature range:
Commercial 0o to 70o C
Extended -20o to 70o C
Industrial -40o to 85o C
The temperature testing and certification method is explained in the "Industrial
Temperature Support" page, available following the [Products] >> [Industrial
Temperature] links in CompuLab's web-site.
The mating CM-X270 should be ordered for the same temperature range as the SB-X270.
For example, it is not valid to use a SB-X270 manufactured for industrial temp range with
a CM-X270 manufactured for commercial temp range. Such a combination is practically
limited to the commercial temp range.
