Setting up PCs on a Network

If you have computers running on Windows Server 2003, Windows XP/2000/NT4.0, Windows
95/98 that communicate with NEC Express5800/ft series using the TCP/IP protocol, make the
following settings on all computers.
1. Copy the following in the NEC EXPRESSBUILDER CD-ROM or ft control software,
UPDATE CD-ROM to any directory.
\STRATUS\LANG\EN\PROG\FTREG.EXE
TIPS:
ft Update CD is for updating ft control software. It may not be attached to the
product. If software included in the NEC EXPRESSBUILDER CD-ROM is latest at
the time of shipment, the ft Update CD is not attached.
2. Start up the command prompt and enter the directory in which the file mentioned above is
copied, and then enter the following command.
FTREG.EXE
This setting is to avoid a timeout caused by non-communication state between the NEC
Express5800/ft series and computers connected by the LAN protocol that may occur immediately
after the NEC Express5800/ft series startup or a CPU module reinstallation (dual processing).
Non-communication time immediately after the NEC Express5800/ft series startup or module
reinstallation in the system where Windows Server 2003 runs is proportional to the size of memory
mounted and how much applications running use memory.
Because minimum non-communication time is momentary regardless of size of the memory
installed, it will not be considered as non-communication. Maximum non-communication time by
the memory size is as follows:
Memory size
256MB
512MB
1GB
2GB
3GB
6GB
This setup program sets the following Windows registry:
