IR-320 Technical Reference Manual
software developers no longer need the detailed expertise of each manufacturer’s device or the
standardization of the entire system and the hardware as well as the software. This reduces the
load of developing work.
Software Standardization
When a device control object is created, it is necessary to choose the interface (API) between the
POS application software and the device control module. EPSON has joined an industrywide
and worldwide effort to standardize and spread the use of APIs. The standardized software uses
an OCX driver, which is modularized software divided into two levels: the Control Object (CO)
and the Service Object (SO).
A separate CO exists for each class of device, while a separate SO exists for each individual
device; for example, software that uses a TM-U950 needs a general POS printer CO and a
specific TM-U950 SO. If the TM-U950 printer were replaced by a TM-U375 printer, the TM-U950
SO would have to be replaced by a TM-U375 SO, but the rest of the software, including the POS
printer CO, would remain the same. In other words, a switch from one printer to another
requires only a change in the SO.
EPSON Software
The software products (OCX drivers) that EPSON offers to enable such an OPOS system are
called the EPSON OPOS ADK. The EPSON OPOS ADK provides the OCX driver and much
more. EPSON also provides custom tools to support the construction and development of an
OPOS application software development environment.
Keyboard Firmware Setting Utility for MS-DOS
The Keyboard Firmware Setting utility (PKMODE2.EXE) sets the POS board built in the IR-320.
By using this utility, the keyboard firmware and the MSR unit can be set.
Start
The Keyboard Firmware Setting utility (PKMODE2.EXE) has been registered in the following
directory in the initial setting:
c:\backup\keycfg\Dos\Pkmode2.exe
Prepare a floppy disk of MS-DOS that can be booted, and copy this utility onto this floppy disk.
To start the Keyboard Firmware Setting utility, exit Windows, and reboot the system from
MS-DOS. By inputting the command name from the keyboard, the utility starts.
