1. Installation/uninstallation
•
Do not change the installation structures (see "2. Structure").
•
SPST cannot be installed on a PC if Windows Installer is not supported.
•
The SPST installer does not include MFC that is required to run SPST. If not already installed, install MFC (DLLs including MFC42.DLL).
1.1. System requirements
The following are required for installation.
•
OS: Windows 2000 Professional (SP3 or SP4) or Windows XP Home/Professional (SP1) *1
•
PC: IBM/PC compatible *2
•
HDD: 200 MB available space (or more)
•
RAM: 256 MB or more (512 MB recommended)
•
COM port: Windows compatible serial port
•
Display resolution
XGA or higher
Basically use the default settings in Display Properties, however, small system font size is recommended. *3
(Display Properties → Settings → Advanced → General → Display → Font size)
•
Recommended devices for serial connection between a PC and handsets (phones): *4, *5
The PC's serial port
PCI serial expansion card
USB-UART serial conversion cable *6
Note
*1: SPST does not run on Windows 95, 98, 98 SE, and Me. The behaviour is not guaranteed on Windows XP Media Center Edition/Tablet Edition
and in the Virtual PC environment. Also, its compatibility with upcoming operating systems and service packs is not guaranteed.
*2: A brand name product is recommended. Minimum requirements: 1 GHz Pentium III processor and 256 MB of RAM, and compatibility with USB
2.0 specification for use of USB-UART serial conversion cables.
*3: Depending on the font size, the screen layout may change or some portions and characters may not be displayed on a XGA screen.
*4: Use only the specified PCI serial expansion card and USB-UART cables. Currently, no specific PCMCIA card is recommended.
*5: Transfer rate is 115 Kbps when using a PC's standard serial port. When using a PCI/PCMCIA card or USB-UART conversion cable, its maxi-
mum transfer rate (115 Kbps, 230 Kbps or 460 Kbps) can be selected.
*6: Use cables of either manufacturer only.
[Important] Restrictions for stable operation of Windows/PC (IBM/PC compatible)
When using multiple USB-UART conversion cables, do not connect more than 2 cables (IO-DATA) or 3 cables (NEC) to a USB-HUB/BUS, and do not
change the connection of cables.
Do not connect other USB devices to the PC.
Whilst the PC is in use, avoid connecting/disconnecting cables and USB devices for stable serial communication for Windows/driver.
* SPST may run in other environments, however, the system may become unstable.
