3.1 Communication method by emulator
The supported communication methods are as follows. (The supported communication methods vary
with the type of emulator used. )
USB, LAN, LPT, Proprietary parallel, Serial
3.1.1 USB Interface
Supported only when using the PC4701U emulator.
• Compliant with USB Standard 1.1.
• Connections via USB hub are not supported.
• By connecting the host computer and the emulator with USB cable, it is possible to install the
supported device drivers using a wizard.
• The necessary cable is included with the emulator.
3.1.2 LAN Interface
Supported only when using the PC4701U/HS emulator.
• The IP address, etc. must be set in the emulator before it can be connected in a LAN.
• To communicate with the emulator via a LAN on Windows, Windows' registry information must
partly be modified.
• The PC4701U emulator in a LAN can be connected to the PC4701Us on another network
connected to the LAN via a router.
• The emulators PC4701U and PC4701HS use different LAN cables. Specifically, the PC4701U
uses LAN cable (10BASE-T only) generally available on the market, whereas the PC4701HS uses
the LAN cable (10BASE-T/5) included with it.
• The host computer and the emulator can be connected directly.
3.1.3 LPT Interface
Supported only when using the PC4701U/M emulator.
• This communication uses the host computer's parallel (printer) interface.
• The necessary cable is included with the emulator.
• Four communication modes are supported that include ECP, EPP, Byte, and Nibble.
Communication modes that can be supported depend on the host computer's BIOS settings.
(Communication modes may not always be used even when they are supported by BIOS.)
