Perle 833 Remote Access Server Guide 1
Chapter 1: Introduction
This chapter introduces the Perle 833 Remote Access Server set of products, features and functions.
Perle 833 Remote Access Server
The Perle 833 Remote Access Server is an interface device which allows access to Local Area
Networks (LANs) from the telephone network. Users can dial-in to the LAN from a remote site or
dial-out from the LAN to access a remote host.
Models are available for both Ethernet and Token-Ring LANs, in 2, 4, or 8 port configurations.
Supported Protocols
The LAN connections support the following network protocols
• Novell Internetwork Packet Exchange (IPX)
• Internet Protocol (IP)
• AppleTalk
• NetBios Extended User Interface (NetBEUI)
• Logical Link Control (LLC) and 802.2.
Dial-In
The Dial-In feature allows remote users, using client software, to access a LAN and perform tasks
as if they were directly attached to it, using inexpensive voice-grade telephone circuits and
asynchronous modems.
Remote users can connect to the Perle 833 with a modem using a wide variety of PPP clients or the
Apple Remote Access Client. Among the PPP clients supported are the Perle Remote (for DOS and
Windows 3.x), and the Windows 95 and Windows NT dial-up Networking clients. The Perle Remote
software is provided with the Perle 833 Remote Access Server. See the Perle Remote User’s Guide
(for DOS and Windows 3.x) for more information on the dial-in function. For more information on
other client software, see “Chapter 7: Dial-In” on page 81.

Dial-Out
2 Perle 833 Remote Access Server Guide
Perle 833 Network Topology
Dial-Out
The Dial-Out function allows users on a LAN workstation to connect to a destination that is external
to their LAN. This is done by dialing out via a Perle 833 modem instead of a modem attached
directly to the user’s PC. The user can connect to a BBS, internet provider or any other service
accessible by the telephone network
The benefit of sharing these modems across a network is that they can make efficient use of the
hardware and phone lines that are already installed on the network.
The Dial-Out feature is accessed using the Perle 833 Dial-Out software. See the Dial-Out User’s
Guide for more details on the dial-out function.

Chapter 1: Introduction
Perle 833 Remote Access Server Guide 3
Manager Program
The Perle 833 Manager software is included with the Perle 833 Remote Access Server. It is a
Windows based program that allows network administrators to configure, monitor and manage the
Perle 833 servers on the LAN.
Initial Configuration
In order to configure the unit for the first time, the PC on which the manager is running must
establish communication with the target Perle 833 server. This can be done in one of three ways:
• Over the LAN (Inband)
By connecting both the PC and the server to the LAN, communications can be established
between the two over the LAN using either IP or IPX protocols.
• Direct Connect
By using the direct connect cable provided with the unit, a PC can establish a serial link to the
server via one of the server’s serial connectors.
• Dial-in Connection
By connecting a modem to both the PC and the server, the PC can establish a link.
The following is an overview of the general steps required for each method.
Over the LAN
1. Server Hardware Setup.
Follow the hardware installation procedures as outlined in Chapter 2.
2. For IP networks, set the server’s IP address.
If you intend to assign an IP address to your server via BOOTP or RARP, you do not need to
do anything here since these are the defaults. Otherwise, you will need to enter an IP address
and subnet mask from the front panel under the Configuration LAN Menu. See Chapter 11 for
information on using the front panel.
3. Install the manager.
Install the manager on a LAN workstation. Ensure that the workstation is properly configured
for IP or IPX. If the manager PC is setup for IP, be sure it has an IP address. See Chapter 3 for

Initial Configuration
4 Perle 833 Remote Access Server Guide
further information.
4. Start up the manager.
The Perle 833 manager after startup will automatically find the server on the LAN using IP, IPX,
or both.
5. Login to the server.
Select the server from the list. Then login as superusr with no password.
Direct Connect
Windows 3.1
1. Install the Perle Remote software. Refer to the Perle Remote User’s Guide (for DOS and
Windows 3.x) for details.
2. Configure the Perle Remote software for direct connect and 38400 baud rate.
3. Install the manager.
Refer to Chapter 3 for further information. Reboot your PC.
Note: If the manager PC is to use an IP connection, it must be configured with an IP address.
4. Connect the PC and the server.
Connect the PC to the server using the supplied direct connect cable.
5. Power up the Perle 833.
6. Establish the connection.
Using the Perle Remote Dialer (Windows or DOS), connect to the server. Login as superusr
with no password.
Once this is completed, startup the manager. After selecting and connecting to the Perle 833,
you will be asked to log in a second time. Use superusr again.

Chapter 1: Introduction
Perle 833 Remote Access Server Guide 5
Windows 95
1. Install the Manager on your PC.
2. If your Windows 95 Modem List does not have a direct connect modem type, do the following
steps:

e) From the model list choose Direct Connection.
f) Select your COM port.
3. Set up a dial-up networking connection using the direct connection created above. Set the baud
rate at 38400.
4. In your dial-up network connection, make sure that you have enabled either IP or IPX.
5. For IP connection, set your TCP/IP settings so that the client (your PC) is supplying its own IP
address and enter the address you wish to use.
6. If you are using an IP connection, you will need to set up an IP address and subnet mask in the
Perle 833 server. This can be done through the Front Panel under the Configuration LAN menu.
See Chapter 11 for information on using the Front Panel.
7. Using the supplied cable, connect the PC to the Perle 833 server.
8. From Dialup networking, start the Dial-up Session. Login to the Perle 833 as Superusr with no
password.
9. Start up the manager. After selecting and connecting to the Perle 833, you will be asked to log
on a second time. Use Superusr again.

Initial Configuration
