AR-NC5J/NC5JG/NC5JW - 1
[1] GENERAL
The AR-NC5J is a print server with Falcon 32bit RISC chip, which
automatically switches between 10BASE-T/100BASE-TX, conforming
to network protocols of TCP/IP (Windows95, Windows98, WindowsMe,
WindowsNT4.0, Windows2000, UNIX), IPX/SPX (Netware), AppleTalk
(Macintosh), and NetBEUI (Windows95, Windows98, WindowsMe,
WindowsNT4.0, Windows2000). The 32bit CPU, together with the
automatic switch of 10/100BASE, provides high-speed process. This
server allows to share printers in a wide range of network environ-
ments from a small-sized network by means of NetBEUI to a large-
scale network where two or more network protocols are intermingled.
[2] ENVIRONMENT
1. Items required for connection to a
network
• Shield-type, twisted-pair cable (A cable of Category 5 is required for
100BASE-TX.)
• Printer
2. Network computer
• Windows95/98/Me/NT4.0/2000
(One of TCP/IP, NetWare, or NetBEUI must be available.)
• UNIX
•NetWare
• Macintosh (AppleTalk must be available.)
[3] MAJOR FUNCTIONS
1. Functions
A. Automatic IP address setup by DHCP, BOOTP,
RARP
(1) DHCP/BOOTP
The AR-NC5J, equipped with the DHCP/BOOTP protocols, allows to
make setups related to TCP/IP in a network where a DHCP/BOOTP
server is working.
By enabling the DHCP/BOOTP setup of the AR-NC5J, the information
related to TCP/IP which is valid in the DHCP/BOOTP server can be set
to the AR-NC5J.
• The DHCP protocol supported by the AR-NC5J basically conforms
to RFC2131/2132. It conforms to Windows NT DHCP servers.
• To utilize the DHCP function of the AR-CN5J, consult the network
manager.
(2) RARP
The AR-NC5J, equipped with the RARP protocol, allows to make setup
of IP address in a network where a RARP server is working.
By enabling the RARP setup of the AR-NC5J, the IP address set in the
RARP server can be assigned to the AR-NC5J.
B. IPP conformity (TCP/IP)
The AR-NC5J conforms to the Internet printing protocol (IPP Ver.1.0)
which allows to print via the Internet. By using the IPP, it allows to print
with a remote printer as well as Web access by HTTP.
C. WWW browser
The AR-NC5J, equipped with the HTTP server, can be accessed by a
WWW browser to display the printer status or to change the printer
setup.
• For operations of HTTP, it is recommendable to use a WWW
browser such as Internet Explore4.0 or later or Netscape
Navigator4.0 or later. If another browser is used, it must at least con-
form to HTTP1.0 (RFC1945) or HTML2.0 (RFC1866).
• To use HTTP, the TCP/IP protocol setup of the AR-NC5J must be
valid and the IP address of the AR-NC5J must be set.
