Introduction
Ringdale’s Token Ring - Ethernet TCP/IP Router provides a
solution for connecting a single Token Ring device (through a
MediaAccessUnit)toanEthernetnetwork. Thisallowsadevice
with a Token Ring network connection (for example Printers,
Laptops and network peripherals) to be attached to an Ethernet
network.
Ethernet connection is made with an RJ-45 connector,
configured to allow a crossover cable to run to the 10baseT
Ethernet Network.
Token Ring connection is made using a type 1 cable on a 9-
way DB connector or type 3 cable on an RJ-45 connector. The
router has the ability to automatically sense which Token Ring
connection is used and the Token Ring speed, at either 4MHz
or16MHz.
The router is configured and managed remotely using
Ringdale’s PeripheralVision®network management software
that can be installed on any Windows 95/98/ME/NT4/2000 PC
on the Token Ring network.
Follow the steps detailed in this manual for quick installation
of the Token Ring - Ethernet TCP/IP Router.

Connecting the Router to the Ethernet Network
Insert a Crossover RJ-45 10baseT cable from the Ethernet
network into the RJ-45 port on the Ethernet panel.
The Green RX LED will blink when the router receives data
from the Ethernet network.
The Red TX LED will blink when the router transmits data to the
Ethernet network.
The Yellow Link LED indicates that the Ethernet network
connection is functioning.
Connecting the Router to the Token Ring Device
Connect the Token Ring device to the MAU (the type of cable
required will depend on the type of connections being used).
Insert either a Type 3 cable with a RJ-45 connector or a Type 1
cable with a 9 way DB connector from the Token Ring MAU into
theRJ-45 or DB 9 porton the Token Ring panel. The routerwill
autosense which Token Ring connector is being used.
The Red Error LED will light when there is an error with the
Token Ring devices.
The Green RX LED will blink when the router receives data
from the Token Ring device.
The Red TX LED will blink when the router transmits data to the
Token Ring device.
Powering the Router
Important Note
If there is a delay in connecting the router to the Token Ring
MAU after power-up, it may be necessary to restart the router in
order to make the Token Ring link good.

8
Connect the power cable to the Power Supply socket on the
Ethernet panel of the router. Connect the other end of the
power cable to the mains electricity supply.
Configuring the Router
Once the router is installed it is necessary to configure the
device. Configuration is accomplished by using the
PeripheralVision®software supplied with the router (see the
following chapter for details on this).

9
Using PeripheralVision®to Configure the Router
Full operational procedures for PeripheralVision
®
are detailed
in the program helpfile, refer to this if any problems are
encountered in the procedure detailed below.
1 Install PeripheralVision®onto a PC on the Ethernet network.
2 Ensure the router hardware installation is complete.
3 Using the Locate NPMPTM discovery tool in
PeripheralVision®, enter the default set IP
address (11.22.33.44). The router will appear
on the network map, it will be an icon similar to
the example on the left.
4 Left click twice on the icon to open up the property pages of the
device. The default displayed page will be the Name page.
This is shown below:
5 In the Icon Title field enter a name for the router that will allow it
to be identified on the PeripheralVision®network map.
6 Using the arrows in the top right corner, scroll the pages and
click on the first IP Router page. This is shown following:

10
The following information needs to be entered onto this page
(this will be supplied by your network administrator).
IP Address Enter here the router’s IP address for the
Ethernet network (this will be the gateway for all
Ethernet devices that need to communicate with
the Token Ring device).
TCP/IP Subnet Mask Enter here the subnet mask for the Ethernet
network.
Default Gateway IP Address Enter here the IP address of another router.
This will allow packets for unrecognized IP
addresses to be redirected to that router.
DNS Name Server Address Enter here the IP Address of the DNS server
if required (optional).
Local IP Address Enter here the router’s IP address for the Token
Ring side (this will be the gateway for the Token
Ring device).
Local IP Subnet Mask Enter here the subnet mask for the Token Ring
side.
Click on Apply to register the new information.

11
Passwords
It is strongly recommended that Passwords are set for access
to all router property pages in PeripheralVision
®
because of the
sensitive nature of the information that can be configured.
If required, access to set/change the information on the router
property page can be restricted using the Change Password
button. Click on it to bring up the following window:
Enter the Password into the box, type in the confirmation and
click on OK.
Access to change the configuration will now be restricted to
those who have the Password.
Routing Table Page
7 Itisnownecessarytotell therouterwhereto routetheIPpackets.
This is done by creating a Routing Table. Use the arrows to
scroll the pages and select the Routing Table page. Make
surethatthe whole IP range is passed over totheothernetwork.
Any packets that are not in this range will be passed onto the
Default Gateway Address . An example of this setup is shown
following.
To configure each route, click on the Add Route button and
enter the information as described:

12
IP Address Enter here the IP address of the subnet/range
you want to route to (enter a zero in the last
segment of the IP address for each range).
Subnet Mask Enter here the Subnet Mask of the above IP
Address, either for the Token Ring side or the
Ethernet network.
Gateway Enter here the IP address of the router for the
side of the network the above IP addresses are
on (for example, if the IP addresses are on the
Ethernet network, enter the address assigned to
the first
IP Address field previously - for the Token
Ring side use the address assigned to the Local
IP Address field).
H (Hops) Enter here the number of hops across networks
orsubnetsthat are necessary to route the packets
to the required IP Address.
IF (Interface) This remains at the default setting of 1.
Select a route from the list and click on the Edit Route button to
change the configuration of an existing route.
Select a route from the list and click on the Delete Route button
to remove a route.
Once the routes have been set up as required, click on Apply.

13
8 Once the routing table is finished, ensure that each separate
device that is using the router as a gateway has the correct IP
address (the one set up for it in the routing table) entered as
the gateway (for example, for a PC on the Token Ring side to be
able to communicate with devices on the Ethernet network, the
router’s Local IP Address will need to be entered as that PC’s
gateway - for a device on the Ethernet network the router’s first
IP Address will need to be the gateway).
9 To check that the router is set up correctly, ping the device on
the Token Ring side from a device on the Ethernet network.
Then, if possible, ping a device on the Ethernet Network from
the Token Ring device.
Broadcast Forward Page
10 The router also has the facility to forward broadcasts. Select
the B’cast Forward page, which is shown below:
To forward a broadcast through the router to the required IP
address click on Add.
Enter the IP address and click on OK. The IP address will be
entered into the list.
To make changes to an IP address already on the list, click on
the required address to select it and then click on Edit. This

14
will open the above window with the IP address you wish to
edit. Make the changes and click on OK.
To delete an IP address from the list, click on the required
address to select it and then click on Delete.The IP address
will be removed.
Click on Apply to save any changes you make.
PeripheralVision®Licensing
PeripheralVision®software comes licenced for 30 days, after
which time a full licence can be purchased to continue access
to all the facilities of the program.
This does not affect your ability to use PeripheralVision®to
configure the router.
These features are operational whether the software is licenced
or not.

15
Token Ring Speed Settings
The router will autosense the Token Ring speed of 4MHz or
16MHz. This is the default setting.
In exceptional circumstances it may be necessary to manually
set the Token Ring speed.
To do this, un-clip the casing of the unit (ensuring that it is
disconnected from the power supply). The Token Ring speed
pins are located on the circuit board and are easily identified by
a red jumper. The layout is shown in the diagram below.
The red jumper will be over the Auto pin only, enabling the
router to select 16MHz or 4MHz as required. To set one speed
only, remove the jumper and replace it over the Auto pin and
the pin of the speed you wish to set, as shown in the diagrams
below.
After the setting has been selected, replace the casing again
and the router will operate only to the speed selected.
