RISO-ADMIN features

[TCP/IP] tab

The network configuration of a RISO printer which is required for TCP/IP communication can be specified here.

1) Use DHCP

You can automatically assign TCP/IP addresses to

RISO printers on the network using a DHCP server when

this check box is selected. In this case, you do not have

to specify TCP/IP addresses in this tab. In normal condi-

tion, however, a different IP address will be assigned to

RISO printers on the network each time you turn on the

power switch of them, causing problems in printing doc-

ument data. To prevent the above-mentioned problems,

you can change the configuration of the DHCP server.

See the [Help] message on the DHCP Manager for

detailed descriptions about the DHCP server.

2) IP Address

This is the basic address of all devices which are con-

nected to the TCP/IP communication network. Each

device, including RISO printer, should have a unique

combination of these 4 numbers which range between 0

and 255 to communicate with other ones on the network

using the TCP/IP network protocol.

3) Subnet Mask

This combination of 4 numbers, normally 0 or 255,

defines the size of the current network, i.e. the number of

devices (terminals) within the network which can be

entered through a single router. This is applied to the IP

address to divide it into two different types of addresses,

i.e. network address and device (terminal) address. This

must be the same among all devices on the current net-

work.

4) Gateway Address

This combination of 4 numbers indicates the IP address

of the Default gateway (router) on the current network. If

you want to grant access to the RISO printer selected on

the current network from outside the gateway (router),

enter the IP address of the gateway (router) on the net-

work in which the selected RISO printer exists.
