1.0 Product Description
The SystemConsoleSwitch (SCS) allows a user to control and monitor a maximum of 120
devices from a single terminal. Extensive port buffering facilitates trouble shooting by allowing
the user to scroll back and forth through 30* screens (32 Kbytes) of data per port. The remote
access feature allows a user to connect to the SCS and monitor systems from an off-site
location. Password protection ensures access security.
1.1 Features
lConnect up to twelve RS-232C compatible ports
lDaisy-chained units allow connection of up to 120 devices
l30 Screens of Buffered Data Storage per Device
lRemote Access via Modem Port
lSecurity Password
lConfigurable Modem/Auxiliary Port
lParallel Printer Port
* The number of data screens will vary, depending on the data displayed.

2.0 System Overview
2.1 Connect up to twelve RS-232C compatible ports
The SystemConsoleSwitch (SCS) is plug compatible with any RS-232 device. Daisy-
chained SystemConsoleSwitches can control up to 120 terminal ports (maximum
recommended). These may be a variety of network servers, routers, and any other
LAN/WAN computers on the network. Access to any one of the connected ports is
achieved through simple keyboard commands (channel selection) through the attached
terminal.
2.2 Buffered Data Storage
Dual Spooler modules allow storage of up to 30 screens (32 Kbytes) of data per device.
Each dual spooler module contains circuitry to support two totally independent devices.
Data storage is continuous for all connected devices. Each SCS is expandable to
accommodate up to six dual spooler modules, allowing 12 devices to be connected.
2.3 Direct and Remote Access
There are two means of access for the SystemConsoleSwitch. One method of access is
through a terminal that is directly connected to the SCS. The alternate method is to use a
dial-up modem from a remote site. Both means of access gives the user the capability to
monitor activity from any connected device, and to interact with each device directly.
2.4 Security Password
The remote access feature requires a password to complete the connection to the SCS.
Should the user fail on their third attempt to enter a password, the SCS will automatically
disconnect the user.
2.5 Configurable Modem/Auxiliary Port
The built in modem port may also be configured to function as an auxiliary terminal port.
This features allows the user to have two consoles (terminals) in different locations.
Switches for the Modem/Aux port may be changed while the power is on, without
interruption to the unit.
2.6 Parallel Printer Port
Another significant feature of the SystemConsoleSwitch is the printer port. The user may
select any portion of the stored data and obtain a hard copy from a printer connected to
the printer port.

3.0 System Components
Each SystemConsoleSwitch consists of three major components, the chassis, spooler
modules and the external power supply.
3.1 Chassis
The chassis contains two circuit boards; the Master Circuit Board and the Switch Board.
Dip switches on the master board allow the SCS to be configured at various baud rates
for the terminal and modem ports (refer to section 4.1, step 2 for detailed instructions).
The Switch Board's main function is device selection, and has no user adjustment. The
chassis is equipped with slots to house up to six dual spooler modules.
3.2 Spooler Modules
Each spooler module contains circuitry to support two totally independent ports. There
are two sets of dip switches on the spooler module for baud rate selection of the
attached device. Each set of dip switches are independently set to be compatible with
its corresponding device. Additionally, dip switches are provided on the spooler module
to select the number of data bits per byte, the number of stop bits, and parity (refer to
section 4.1, step 3 for detailed instructions). It should be noted that each of the dual ports
on the spooler module function independently, both in terms of memory and
communication.
3.3 External Power Supply
Power is supplied to the SCS through a +5V DC power supply, which is plugged into a
grounded 100-250 volt AC outlet.
3.3 System Cable Requirements
Device connections are made with the RJ45 connectors on the rear panel and DB25
male/female as well as DB9 male/female adapters for user equipment.

This connector style is common to a variety of network cabling schemes and may be
purchased from Lightwave Communications Inc. Refer to Appendix A for cable part
numbers. The following cables connect the terminal, printer, modem, auxiliary and CPU
ports:
lSystemConsoleSwitch to Terminal: Use a straight 1:1 DB25 to DB25 cable (P/N
200.0126, supplied with unit -15' included, contact your representative if a different
length is needed).
lSystemConsoleSwitch Parallel Port to Parallel Printer: Use a parallel printer
cable.
lSystemConsoleSwitch Modem Port to Modem: 1:1 modem cable.
lSystemConsoleSwitch Modem Port to Terminal: Null modem cable.
lSystemConsoleSwitch CPU Ports to CPU: Cabling is RJ45. DB25 and DB9 to
RJ45 adapters are available for device connection.
NOTE: Local Area Network (LAN) cables may be used with the SystemConsoleSwitch
because they are pinned straight through (1:1). Do not use Telephony RJ45 Cables as
they have crossed pinouts and damage to the attached devices or the
SystemConsoleSwitch may occur.

4.0 Installation Instructions
Use the following procedure to install a single SystemConsoleSwitch.
4.1 SystemConsoleSwitch Installation
Refer to Appendix A for Rack Mount SystemConsoleSwitch Diagrams
Step 1: Identify the following items in the shipping container (see figure 2)
lSystemConsoleSwitch Chassis (stand-alone or rack-mount)
lAC power cord
l+5V DC power supply
lPower Supply Cord Retainer Clamp (located on DC power cord)
lDB9 serial cable for cascading the SCS
Important: Before beginning the installation procedure, re-seat the master board,
Switch Board and each spooler module board, as shipping may
dislodge them.
