APPLICATION GUIDES
POWER SUPPLY TO I/O PORTS
Through BIOS Setting, the +5V DC supplies to the devices connected to COM port
and the +12V DC supply to the VGA connector can be enabled or disabled. Through
jumper setting, the +12V DC supplies of COM port can be enabled or disabled. The
power supplied from the TX-3700 series to all USB devices on 5 V DC is limited to be
within 2.0 Ampere total. The +5V DC in all COM ports is limited to be within 1
Ampere total. The power supplied to VGA port on 12 V DC is limited to be within 1
Ampere. Nevertheless, the ventilation of the environment should be much improved to
compensate the heat accumulation due to such excessive load.
For the power supply of serial and VGA ports, it can be set up through BIOS setting.
Once switch on the terminal, press “Del” key to enter BIOS. Please select “Integrated
Peripherals” in the main menu as well as choose “SB GPIO Control”. Afterward, there
are COM 2/3 DB9 +5V and VGA +12V setup function which can be selected. Please
remember that if there is no need for power supply in these I/O ports, please disable
these functions.
CUSTOMER DISPLAY
The RS232 model rear base mount customer display upgrade kit such as PD-7630 can
be connected to be available with the internally supplied power from the TX series set
per BIOS setup. The USB model PD-2606/330 can be connected to any available USB
port with an internally supplied power from the TX-3700 series. Please refer to the
user’s manual of customer display for detailed instructions on use of PD. Please refer
to earlier chapters if COM1 is selected for this usage.

TX-3700 series Technical Manual 17
CASH DRAWER
In TX-3700 system, the software command to open the cash drawer or the first cash
drawer with the optional 2 in 1 cash drawer control cable is a hexadecimal code of
<07> sent to COM1 port under the protocol of 9600 bps, none parity, 8 data bits, 1 stop
bit.
The software command to open the second cash drawer with the optional 2 in 1 cash
drawer control cable is a hexadecimal code of <17> sent to COM1 port under the same
protocol as above.
The drawer open status can be obtained through checking the communication status of
COM1 at signal RI. When there is no drawer open, the RI signal of COM1 is always
set. When there is any cash drawer opened, the RI signal of COM1 is reset. The RI
signal is obtained as the bit 6 (the second most significant bit) of the I/O address 3FEh
if the COM1 address is set to 3F8h~3FFh (conventional address for COM1) in system
configuration.
POWER ON/OFF CONTROL
AUTOMATIC POWER ON CONTROL
When the system is turned off after a successful boot up, the preset automatic power on
functions, if set as below, will keep monitoring for the preset conditions and turn on the
system when the preset conditions are met.
Please note that if the system is improperly turned off before a complete boot up
procedure, the above preset power on control functions will be disabled until turning
off next time after a complete boot up.

TX-3700 series Technical Manual 18
ALARM CLOCK WAKE UP
To utilize Alarm Clock Wake Up function, the user should enter the CMOS setup by
pressing “Del” key at system boot up, choose “Power Management Setup” and make
the “Resume by Alarm” enabled and set the alarm to required time. Save the
configuration and exit the CMOS setup program. The Preset Power on Control will
then be ready.
CAUTION: Please notice that when EuP function is enabled, the alarm clock
wake up function will be disabled automatically.
MODEM RING UP
To utilize Modem Ring Up function, the user should enter the CMOS setup by pressing
“Del” key at system boot up, choose “Power Management Setup” and make the “Power
On by Ring” enabled and connect the RS232 modem to COM1 port. Save the
configuration and exit the CMOS setup program. The Preset Power on Control will
then be ready.
LAN WAKE UP
For LAN wakeup, the item “PCI Express PME” must be enabled in item “PCI Express
PM Function” of “Power Management Setup” in BIOS setup and an operating caller
system connected through LAN to the system is required. It also requires a qualified
networking technician to check the LAN chip ID of the system for the caller system to
wake up. In this application, there is need for 1 master machine and 1 target machine
connected together through LAN.
To get LAN chip ID (MAC address) of the target machine, please run the target
