RT-101 User’s Manual

How the RT-101 Works

The RT-101 gives users across your network access to the vast resources available on the Internet. Once the RT-101 is installed and configured, the Internet is just a click away.

The RT-101 is assigned a unique IP addresses that allows it to communicate directly with the Internet. Activating your browser and inputting a URL (Universal Resource Locator) produces a Internet bound data package that is routed through the RT-101 to Internet. Additionally, since dial up line fees are dependent on line usage, the RT-101 supports the following cost saving functions:

IP Spoofing

IP protocol tends to be quite talkative; that is, it is always requesting and sending RIPs (routing information packets) to detect any change in resource status-- servers, routers and other peripheral devices. Spoofing is a means of filtering the chatter (RIPs) so that when no important data is present the line can be dropped as defined by the Disconnect time-out setting. After the line is dropped, the spoofing mechanism fools the local network into thinking the line is still up and that the Internet

resources are still available. Without spoofing, the line would remain up indefinitely and huge line fees would be incurred.

Dial On Demand

Dial On Demand is an intelligent feature that monitors the

dropped communication link for transmission activity. If activity is detected, a connection with the Internet will automatically be re-established. To the user, it is as if the line were never dropped.

RT-101 User’s Manual

Serial Port

The following options allow you to set the parameters that define how the serial interface is configured for data transmission.

UPD Checksum:

Set this option to Yes to enable UDP Checksum. UDP Checksum provides a check on all transmission data to ensure data reliability. When the UDP Checksum function is set to No, the device ignores UDP checksum on incoming packets and uses zero checksum on out going packets.

Periodic RIP:

Select this option to allow the RT101 to pass periodic RIP (routing information) packets across the WAN interface. The default setting is Yes; however, when unnecessary this increases the traffic on the WAN link. Before changing this setting ensure that the ISP

router does not RIP updates.

Generate Zero Fill (BSD 4.2) Broadcast Address:

This option is provided for compatibility with those networks which have early implementations based on UNIX BSD4.2. Setting this option to Yes will cause all outgoing broadcast IP addresses to be translated into Zero Fill type addresses.

Use Ethernet IP Address and Network Mask:

Set this option to Yes to use the

3 LAN INSTALLATION

Installing your new RT-101 in your existing Ethernet LAN is quick and easy. To install your RT-101, follow the instructions below:

1. Choose an Installation Site

Select a place on the network to install the Communication Server unit. Remember that you need phone jacks and power outlets near your chosen location.

2. Connect Network Cable

The RT-101 supports two types of network cables: Thin Ethernet (10Base-2, BNC connector) and Twisted Pair Ethernet (10Base-T, RJ-45 connector). During power up, the unit automatically detects the type of network cable and adjusts to that environment.

10Base-2 Cabling:

If your network uses 10Base-2 cable, insert a BNC Tconnector into the RT-101’s BNC port. Connect the cable to one end of the T-connector and connect the outgoing cable to the other end. If the RT-101 is at the end of the network, then cap off the other end of T- connector with a 50-ohm terminator. Also, keep in mind that the maximum effective length between the ends of a 10Base-2 network is 185 meters.

10Base-T Cabling:

If your network uses 10Base-T cable, insert one end of a 10Base-T cable into the RT-101’s RJ-45 phone jack and the other end into the 10Base-T hub. Keep in mind that the maximum effective length from the hub to the device is 100 meters.

RT-101 User’s Manual

Warning: Do not attempt to connect more than one

type of cable at the same time or change the network cable while the RT-101 is powered On.

3. Connect Modem & Phone Line

Connect the modem, using a standard serial cable, to the RT-101’s serial port. Next, connect a telephone line from an RJ-11 style phone jack to the modem.

4. Connect Power Adapter

Connect the modem power adapter to the modem and the RT-101’s power adapter to the RT-

101. Power both devices On.

Warning: Only use the power adapter provided with the

RT-101. Using a different one may cause hardware damage.

5. Check the LEDs

When the RT-101 is powered On, both LEDs should light, then the Error LED should go off. If the Error LED stays on, there is a hardware problem. Consult your dealer. For more information on the LEDs, refer to the LED Status Table in Chapter 1.

4 OPERATION

Once the RT-101 has been configured and installed in your network, it is ready for use. To access the Internet, follow the steps below:

1. Consult the ISP data sheet and configure the following IP parameters on your workstation:

• IP Address

• Default Gateway

• DNS (Domain Name Server)

2. Activate your Browser.

3. Enter the appropriate destination URL or IP address.

A TROUBLESHOOTING

This chapter covers some common problems that may be encountered while using the RT-101 and some possible solutions to them. If you follow the suggested steps and the RT-101 still does not function properly, contact your dealer for further advice.

Problem 1:

I configured and installed the RT-101 in the network, but I can get it

to respond.

Solution 1:

If the configuration settings are correct, then you probably forgot to set the dip switches back to their Off positions after configuration. Power Off the RT-101 and ensure that the dip switches are in their Off positions.

Problem 2:

Data Transmissions are very slow.

Solution 2:

Check and ensure that the Initial String is configured to RTS/CTS flow control.

Problem 3:

When I enter a URL or IP address I get a time out error.

Solution 3:

Any number of things could be causing this. Try the following troubleshooting steps.

1. If this is first time you have used

RT-101 User’s Manual

your browser, ensure that your workstations IP settings, including IP address, Default Gateway, and DNS are correct.

2. Ping the RT-101. Go to the DOS prompt and enter the following command:

Ping xxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the RT-101 IP address.

3. If the ping command fails, consult your network administrator. The RT-101 may be powered Off.

4. If the ping command is successful, the to ping the remote router.

5. If the remoter router ping command fails, it may mean one of the following:

• The ISP is overloaded

• You have entered the wrong

IP address

• The ISP system is down.

Consult your system administrator for help.

6. If the remoter router ping is successful, then try to ping the DNS. If successful, then you should be able to access the Internet.

Problem 4

How do I configure the RT-101 to work with the ISP (Internet Service Provider)?

Solution 4:

The ISP must provide the customer with basic information concerning security and parameter settings. The data sheet below is from an ISP to a customer who has a router account and is using a dial-up line.

Basic Information:

User Name: Stymme Password: Keepquite Phone Number: 4567890

Setting Parameters:

IP address range: 202.73.93.0-255 Router LAN IP address: 202.73.93.190 Remote Gateway IP address: 167.94.214.254 Remote Name: Charlie DNS IP address: 167.94.197.1 Local Netmask: 255.255.255.0 Local DNS IP address: 202.73.93.161 Remote Netmask: 255.255.248.0

Note: The information received from the ISP will vary

according to the type service you buy and the type of routers used by the ISP. ISPs that use traditional routers will include an additional parameter, Router WAN IP address.

Given the data sheet above, the RT101 main configuration

screen would look like the following:
