Connectors
J12, J7 Power-On LED
(green LED)
Turns on whenever 5 volts is applied. Two 2-pin connectors
operate as a single connector. The pair supports the IBM
2-pin LED connector and the industry-standard 3-pin LED
connector. The 2-pin power LED can connect to J12 or J7.
The 3-pin power LED can be connected across J12-1 and
J7-1, or across J12-2 and J7-2.

J19, J18 Speaker
This consists of two 2-pin connectors. They can drive a
speaker or a speaker LED (in noisy environments). A
standard 8-ohm speaker can be connected to give normal
audio outputs.
The two connectors act as a single header and supports a
IBM 2-pin speaker connector or the industry-standard 4-pin
connector. The 2-pin speaker cable connects to either J19
or J18. The 4-pin cable connects across both J18 and J19
(the two outer-most pins are used).

J15, J27 ATX Power Supply
Used with soft on/off control of an ATX power supply. It
uses a momentary-make on/off switch connected to the SBC
instead of the standard two-pole switch connected to the
power supply. As a result, the SBC controls the on/off
state of the power supply.
When using the soft on/off control, connect a
momentary-make on/off switch to the 2-pin connector (J15),
and connect the 3-pin auxiliary power-supply cable to the
3-pin connector (J27). Note:
Use only a momentary-make switch and a properly-wired
power supply.

Voltage detect |
The logic on the SBC works as follows:
The two connector pins on the SBC are routed to the
detector circuitry. When the pins are shorted, an event is
latched in the detector. The event is latched even if the
computer is turned off or the power cord is unplugged. Bit
6 at I/O address 0158h contains the status of the latch.
If bit 6 is 1, the latch has been tripped. The latch is
reset by setting bit 6 at I/O address 0157h to 1. To use
the logic to detect a cover being removed, the user must
connect a switch that is closed when the cover is removed,
and open when the cover is installed.
Clear
Password
Removing Power-on or System Administrator Password:
1. Turn off computer and remove cover.
2. Short both pads on password clear pad for 10 seconds
-OR- remove battery for 10 minutes.
3. Reinstall cover.
4. Turn on computer and run Configuration/Setup Utility
program.
5. If a password is required, you must enter a new one.
Switch

8 - 3 Reserved Leave these alone.
2 Disable Video Switch 2 lets you disable
the SBC video function. When SW2 is down (on), it disables
all video drivers on the SBC. Default
is video enabled (off).
Disable Keyboard/Mouse
SW1 disables keyboard and mouse ports.
Default position is keyboard and
mouse ports enabled (off).
Switch
Block 2
8 Enable Auto Boot
Switch 8 controls auto-boot feature at power-on. Auto Boot
detects configuration errors at power-on and automatically
alters CMOS settings to match hardware so computer
completes boot process without operator intervention.
Use this carefully because it can mask hardware problems.
Hardware errors could cause the computer to change
configuration and possibly lead to inconsistencies in the
operation of hardware and applications running on the
computer.
Default is auto boot disabled
(off).
4 RS-422/485 or RS-232
Switch 4 controls serial port B electrical interface. If
SW4 is up (off), it is RS-422/485. If SW4 is down (on), it
is RS-232. The default is RS-232
(on).
Internal Processor Clock
Multiplier Switches (Switch Block 2, SW1-3)
Switch block 2 is used to configure the SBC to CPU speed.
SW1-3 select the CPU internal clock multiplier. SW5-7
select input frequency and external bus speed.
