Figure 1-1 gives an isometric view of the system. On the front, the Floppy Disk Drive cover can be
locked up with a keylock.
The receipt printer is under the printer cover while the Customer Display is behind the Operator
Display which is a LCD display .
On the left side, the Power On/Off switch is hidden by a plastic cover which also hide the External
Input Device slide switch for either PC AT keyboard or Bar Code Scanner. The connection port is
hidden by a rubber plug. On the right side, there is the contrast dial knob for the contrast function of
the LCD panel.

Figure 1-2 gives the rear view. With the rear plastic cover removed, the connectors are revealed.
The 25-pin D-Sub connector for the parallel port is on the extreme left while the 3-pin plug for AC
power supply is on the extreme right.
From left to right, the 15-pin D-sub VGA connector for CRT connection, three 9-pin D-sub
connector, 2 RJ-11 connec-tors, which are part of the Printer Controller board, for Cash Drawers
and RJ-45 connector for Ethernet can be seen.
Above the row of these connectors is the 2x5 2mm connector for the Customer Display and another
9-pin D-sub connector for the serial port.

Note: Due to physical construction, there is limitation in

width of the RS-232C connector.
Maximum width is 28.0 mm. Most of ready-made
cables in the market are applicable.

5-7. Serial Port Assignments

For convenience, the serial port table is reproduced here.
The serial ports for the optional operator display and the 2x20 customer display are controlled by
ACER M5105-A4 controller chip.
These ports support only IRQ3 and IRQ4 and can go up to 56Kbps.

To change the default setting, the procedure for changing the setting must be followed.
This is shown in BIOS setup section.
To change the setting, disable all address and IRQ of all serial ports.
Then change from serial port #1.
