ESD Precautions
Computer boards have integrated circuits sensitive tostatic electricity. To prevent chipsets from
electrostatic discharge damage, please take care of the following jobs with precautions:
◼Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
◼Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
◼Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Note
To identify the first pin of a header or jumper, please refer to the following
information:
⚫Usually, there is a thick line or a triangle near the header or jumper pin 1.
⚫Square pad, which you can find on the back of the motherboard, is usually
used for pin 1.
2.3 Jumper Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on
2 jumper pins to close. And remove jumper clip from 2 jumper pins to open. The following
illustration shows how to set up jumper.
Before applying power to MANO321 Series, please make sure all the jumpers are in factory
default position. Below you can find a summary table of all jumpers and onboard default settings.
Note
Once the default jumper setting needs to be changed, please do it under power-
off condition.

2.3.4 Clear CMOS (JP12)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear
the CMOS memory of date, time, and system setup parameters by erasing the CMOS
RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which
includes system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip-on pins 2-3
for about 5~10 seconds, then move the clip back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter
data.

2.4.1 COM1 D-Sub Connector (CN1)
This connector is a standard D-Sub connector for COM1 serial port interface which is
selectable for RS-232/422/485 mode by BIOS setting (see section 4.4). The pin
assignments of RS-232/422/485 are listed in table below.
Note
[*]: Pin 1 of COM1 can be DCD/+5V and pin 9 of COM1 can be RI/+12V by
selecting JP1 (see section 3.3.1).
2.4.2 COM2~COM6 Headers (CN2~CN6)
The motherboard comes with four 2x5-pin (pitch=2.00mm) headers for COM2~COM6
serial port interfaces. It has power capability on DCD# and RI# pins by setting jumper
JP2~JP6.
COM2~COM6:
Note
[*]: COM 2 is RS232/422/485, COM3 ~ COM6 only support RS232.
[**]: Pin 1 of COM2&6 can be DCD/+5V and pin 8 of COM2&6 can be RI/+12V
by selecting JP2~JP6 (see section 3.3.2).

2.4.3 Front Panel Header (CN10)
The CN10 is a 2x7-pin (pitch=2.54mm) header. It includes Power-on, Reset, HDD LED
and Power LED connections, allowing user to connect the PC case’s front panel switch
functions.
Power LED
Pin 1 connects anode (+) of LED and pin 5 connects cathode (-) of LED. The power LED
lights up when the system is powered on.
External Speaker and Internal Buzzer
Pin 2, 4, 6 and 8 connect the case-mounted speaker unit or internal buzzer. While
connecting the board to an internal buzzer, please set pin 2 and 4 closed; while
connecting to an external speaker, you need to set pins 2 and 4 opened and connect the
speaker cable to pin 8(+) and pin 2(-).
Power On/Off Button
Pin 9 and 10 connect the power button on front panel to the board, which allows users to
turn on or off power supply.
System Reset Switch
Pin 11 and 12 connect the case-mounted reset switch that reboots your computer without
turning off the power switch. It is a better way to reboot your system for a longer life of
system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 13 and 14 connect the hard disk drive to the front panel
HDD LED, pin 13 is assigned as cathode (-) and pin 14 is assigned as anode (+).
2.4.4 Digital IO Header (CN11)
The CN11 is a 2x5-pin (pitch=2.00mm) header for digital I/O interface.
