Serial Device
The IR-320 has four serial ports (COM1, COM2, COM5, COM6 ). Also, +5V or +12V can be
output at the 1st pin by the Jumper setting of the main board. The serial ports COM3 and COM4
are internally used for the dedicated TM printer unit/customer display (COM3) and the touch
panel (COM4). Also, the system can be started up by the ring signal from the 9st pin.
To use the serial ports COM5 and COM6, it is necessary to set other unused devices (for
example, parallel ) to disabled (not used) using the BIOS setup and then allocate interrupts for
the serial ports COM5 and COM6.
PCI Slots
The PCI of the IR-320 has the following features:
+3.3 V power supply
Mountable PCI card size
The PCI cards within the dimensional range as shown in the following figure can be mounted.
Three-terminal regulators for the drawer
As with the IR-320, the drawer can be used via the dedicated TM printer unit only when the
dedicated TM printer unit is connected. A three-terminal regulator for regulating the electric
current is mounted on the riser board.
Ethernet Controller
The Ethernet controller is built in the Chipset (Intel 82801BA). This enables operation at 10 Mbps
and 100 Mbps and wakeup from the LAN.
When the main power switch is on (when AC power is supplied), wakeup from the power off
state is enabled. To enable the wakeup, Wake-Up by PCI card should be set enabled in the
BIOS setup.
The operating status of LAN can be confirmed by the LED of the Ethernet connector.
