2. Introduction
The LinkUp 5294 is one of the most feature-rich protocol converters on the market today. For example,
it supports the following:
• IBM PC to System/3X file transfers
• Up to 19.2K baud rate, synchronously and asynchronously
• Dual System/3X hosts
• Packet Data Network Access
• Viral Device Addressing
• Auxiliary printing
• Advanced diagnostic and system information functions
Functionally, the LinkUp is designed to convert an IBM System/3X host’s synchronous (SNA/SDLC)
protocol to asynchronous (and vice versa). It also translates the IBM host’s EBCDIC code to ASCII (and
vice versa). To accomplish these tasks, it emulates an IBM 5251 Model 12 Remote Workstation
Controller, a 5294 Remote Cluster Controller, or a 5394 Remote Cluster Controller. PU Type 1 is
implemented by the LinkUp in all emulations.
The LinkUp attaches to the sync communications adapter on your System/34/36/38 or AS/400. It can
be directly (with just an RS-232 cable) or remote (through synchronous modems).
Once you make the connections, the LinkUp enables almost any ASCII terminal or personal computer
and word processor (with the appropriate terminal-emulation software installed) to appear to the IBM
host as an actual 5251 Model 11, 5291, or 5292 Display Workstation, implemented as LU Type 7. It also
lets almost any ASCII printer to appear to the IBM host as an actual 5224, 5225, or 5256 Printer
Workstation, implemented as LU Type 4. Each of these ASCII devices can be directly or remotely
connected through asynchronous modems.
Figure 2-1 shows a typical LinkUp 5294 application.

3. Features and Applications
This chapter covers the features and applications of the LinkUp 5294.
3.1 Display Emulation Support
The LinkUp 5294 enables almost any ASCII terminal or personal computer and word processor (with
the appropriate terminal emulation software installed) to appear to your System/3X host as an actual
5251 Model 11, 5291, or 5292 Display Workstation. It accomplishes this through a variety of Terminal
Modules.
A Terminal Module is a device driver which is designed after a specific ASCII terminal type, with some of
the terminal type’s unique features incorporated into the module in order to optimize its performance.
NOTE
Any terminal (or terminal emulation software) capable of simulating the terminal type of
a specific module can also be supported by that module. See Appendix D for a
complete list of the various terminals, personal computers, and word processors
currently supported by the LinkUp 5294.
Each Terminal Module has a full implementation of all of the 5250 screen handling facilities, such as
attributes and cursor positioning, and most of the keyboard functions. The specific display attributes
supported by the LinkUp include the following:
• Reverse Image
• Column Separator
• Non-display
• High-Intensity
• Blink
• Underscore
Any combination of these is also possible.
However, these facilities are supported only as well as the terminals in your application support them. In
other words, if the terminal in your application does not support one of the listed attributes, the LinkUp
5294 cannot implement that attribute for the terminal.
Another feature is Screen Optimization. Instead of clearing and repainting a terminal’s screen of data
for every new update, the LinkUp simply repaints the terminal’s screen with only the updated new
characters, keeping the amount of screen painting to a minimum.

12
Each of the 5250 keyboard functions supported by the LinkUp Terminal Modules has been
implemented in a manner most suited to the keyboard layout of the particular terminal that the module
is designed after. The supported 5250 functions are listed below:
CURSOR MOVEMENT
• Character Backspace
• Cursor Up
• Cursor Down
• Cursor Left
• Cursor Right
• Field Advance
• Field Backspace
• New Line
• Fast Left

NOTE
Appendix F lists all the currently supported terminal modules and the unique key
sequences assigned for each of their supported 5250 functions.
In addition to the standard 5250 keyboard functions supported by the LinkUp 5294, the following eight
extended functions are provided:
• Local Copy Print Request — prints the contents of your screen to a printer configured and assigned
to a terminal (or terminals) as a Local Copy printer.
• Local Copy Form Feed — sends a form-feed command to the printer configured and assigned
to a terminal (or terminals) as a Local Copy printer.
• Cancel Print — cancels a print request sent to a printer configured and assigned to a terminal
(or terminals) as a Local Copy Printer.
• Refresh Screen — redisplays the last transmitted CRT screen on the screen buffer stored
within the LinkUp 5294. This key is useful when a terminal’s display is garbled by line errors.
• Toggle Status Line/Toggle Indicators — toggles the display of the status indicators generated
by the LinkUp to Row 24 of a terminal’s screen.
LINKUP 5294 WITH DL5294 FIRMWARE
14
• Toggle Echoplex Enabled — toggles the ability of the LinkUp 5294 to echo characters to a terminal’s
screen. This function will wait only if you configure it as such in the LinkUp Configurator Mode.
• Initialize Terminal — causes a terminal to reinitialize without resetting the LinkUp port to which the
terminal is attached. You are exited from the System/3X host session (referred to as Emulation
Mode) and returned to the LinkUp sign-on menu (called Connect Mode) even if the LinkUp 5294
has been configured to prevent access to this operating mode. When this function is invoked, the
host is informed that the workstation’s power has been turned off.
• Request Disconnect — similar to Initialize Terminal in that it exits you from the System/3X host
session (Emulation Mode). However, unlike Initialize Terminal, it will reset the LinkUp port to which
the terminal is attached. The LinkUp resets its port by dropping DTR if it is configured as a DTE
interface or DSR if it is configured as a DCE interface. When a terminal is remotely connected to the
LinkUp by asynchronous modems, this function will cause the modem to hang up. And like Initialize
Terminal, this function informs the host that the workstation’s power is off.
Another LinkUp feature is a Status Line of five indicators displayed on row 24 of an attached terminal
while it is operating in Emulation Mode. The LinkUp displays this line the first time a terminal enters
Emulation Mode; thereafter, you may toggle it on or off with the key sequence corresponding to the
extended function of Toggle Status Line/Toggle Indicators. These indicators are listed below:
• SYS AVAIL: — System Available indicator is set (turned on) whenever the terminal is receiving polls
from the System/3X host.
• MSG WT: — Message Waiting indicator, controlled by the host, is set whenever you have messages
waiting to be read.
• INS MODE: — Insert Mode indicator is set whenever [INSERT] is pressed. Insert Mode can be reset
(turned off) by pressing the [ERROR RESET] or one of the Aid Generating keys.
• INPUT INH: — Input Inhibited indicator is set after an Aid Generating key is pressed. This indicates
the keyboard has been locked by the host and you should not type any data. The System/3X host will
reset this indicator after is has completed the requested data processing. (Operator errors will also
cause this to be set.) Only System Request and Attention keys are valid while input is inhibited.
• AWFER: — A Waiting Field Exit Required indicator is set when data is entered into the last position
of a field the host has marked as requiring the function of Field Exit to be invoked. It is reset once
the field is exited. (On an actual IBM workstation, the cursor blinks to indicate AWFER).
Support for a 25th line Status Line display is available for the following terminals: Hazeltine Esprit
10/51, Lear Siegler ADM-11, TeleVideo 925, Wyse 30, Cyberne XLB-5291, Rebus 3000, and
FileLynx/5251. The status display is exactly the same as it had been on line 24, and the Toggle Status
Indicators keystroke is accessed in the same manner.
Because of design characteristics of the Wyse 30 and the Cybernec XLB-5291, the ERROR nnnn-mmmm
portion of the Status Line in columns 64 through 79 of the 25th line is sometimes unable to display at
the proper time. As this part of the Status Line is displayed only in the event of an error between the
LinkUp and the System/3X, this limitation should be of little or no consequence to you.
NOTE
If the host or terminal attempts to write data to Row 24 while the Status Line is on, the
LinkUp automatically toggles the Status Line off and displays the data.
CHAPTER 3: Features and Applications

3.2 Printer Emulation Support
The LinkUp 5294 enables almost any ASCII printer to emulate IBM 5224, 5225, or 5256 Printer
Workstations via its 12 distinct Printer Modules. Eleven of the Printer Modules are designed for specific
ASCII printer types. They Make use of particular features of the printers so as to optimize the module’s
performance. The twelfth module is a generic PRINT module.
NOTE
Any printer that can emulate a printer supported by one of the Printer Modules can also
be supported by that module, but the support is only as good as the emulation. See
Appendix C of this manual for a list of the various printers currently supported by the
LinkUp.
The LinkUp does not currently support all SCS commands. See the Table 3-1 for a description of which
printer module supports which SCS commands.

• GEN44
• HPDPL

• HPDPP
• HPGEN
• OKIM84
• PRINT
NOTE
Because of a design characteristic of the Genicom®and GE3000 printers, the LinkUp
must select a character font at the same time it sets character density (10 cpi vs. 15
cpi). As character fonts are not otherwise selectable in LinkUp, whenever it receives a
Set Character Density command from the System/3X host the LinkUp sets the GEN34,
GEN44, or GE3000 printer to the DP (draft quality) font. If another font is desired, it
must be selected manually and the LinkUp must not be sent an SCD command.
The PRINT printer module does not support Set Line Density or Set Character Density.
For those printer modules which support 15 characters per inch character density, the
LinkUp can be set, through SCS commands, to support 198 column printing regardless
of what line length is configured in the printer LU. The SCS commands can override the
configuration.
Once the appropriate configuration parameter values are defined, the LinkUp can support a printer
by three different connections:
1. When the printer is directly connected to one of its asynchronous ports.
2. When the printer is remotely connected to one of its ports through asynchronous modems.
3. When the printer is sharing one of its ports with a directly or remotely connected terminal, personal
computer, or word processor, through the terminal’s auxiliary port.
Situation #3 is called the Auxiliary Printer facility of the LinkUp 5294. See Figure 3-1 for a diagram
of this facility.

CHAPTER 3: Features and Applications
17
When this facility is activated, a printer attached to a terminal’s auxiliary port is addressed by your
System/3X host (and the LinkUp) as if it were attached by its own distinct line, with full System/3X
printer emulation capabilities. The difference between a printer attached to its own LinkUp
asynchronous port and one sharing a port with a terminal through the terminal’s auxiliary port is the
process of interleaved printing—two devices sharing a single port are operated concurrently and are
instructed by the LinkUp to alternate, with the terminal having priority over the printer.
A choice of two distinct printer operating modes can be defined in the LinkUp Configurator Mode:
• System printing
• Local Copy printing
A System printer is one that accepts print jobs from the System/3X host. A Local Copy printer is one
which accepts a command from you to print the contents of a terminal screen. To invoke a local copy
print request, you must press the key sequence (appropriate for the selected Terminal Module)
corresponding to the extended function of Local Copy Print Request.
NOTE
If the following conditions are not met, a Local Copy Print Request will be ignored and
no error message will display.
The printer must be defined in Configurator Mode as LOC, indicating a Local Copy
printer.
The printer must be associated, through Configurator or Connect Mode. to the terminal
attempting to invoke the Local Copy Print Request function.
The printer must not be currently printing another terminal operator’s screen (as it is
possible to assign the same printer to more than one terminal operator).
If transparent transmission of Escape sequences to ASCII devices is desired, the LinkUp will translate
EBCDIC Hex BB to ASCII Hex IB (Escape) for this purpose when using the US character set.
The LinkUp supports the System/3X host’s printer SIGNAL requests:
• printer intervention required
• printer component available
“Printer intervention required” is sent by the LinkUp when a Printer Workstation goes off-line; for
example, if the power is turned off or paper runs out. When this SIGNAL is received by the host, the
print job is halted. Once the printer is restored to an on-line state, the LinkUp sends “printer
component available” to the host, which causes the host to start the interrupted print job from where it
left off. This procedure assures you that no loss of data occurs.
When a printer is connected to the LinkUp by its own port and its connect mode parameter has been
configured as dedicated, the device ready signal (specified in Configurator Mode) is used by the LinkUp
to determine when to send the SIGNALs. However, when its connect mode parameter has been
configured for automatic answering, the LinkUp is unable to implement this facility. This is because,
when the device ready signal drops, the LinkUp disconnects the device from its coupled session.
LINKUP 5294 WITH DL5294 FIRMWARE
18
NOTE
The printer attached to the LinkUp must be obtained so that its device ready signal
matches the value configured in the LinkUp.
The conditions under which the LinkUp implements printer SIGNALs for an auxiliary printer are
different. Since an auxiliary printer is connected to the LinkUp by a terminal, it cannot directly
communicate with the LinkUp—it must rely on the auxiliary port provided by the terminal it is attached
to. Therefore, if the terminal cannot relay to the LinkUp the auxiliary attached printer’s off-line and online states, the printer is restricted to following the off-line and on-line transmissions of the terminal.
3.3 Virtual Device Addressing
With “Virtual Device Addressing,” the LinkUp is able to support as many as 32 distinct devices. Virtual
device addressing allows the LinkUp to recognize each device that attaches to one of its ports through
a logical address; or, in other words, logical unit or LU number.
A logical unit and a physical asynchronous port are said to be coupled after you complete signing on
to the LinkUp during Connect Mode. However, being physically connected to Port 3 does not mean
you have to specify LU 3 as your assigned logical unit. Instead, by virtual device addressing, the LinkUp
allows you (and your terminal operators, providing you do not configure the asynchronous port’s
associated logical unit as non-overridable) to specify any one of the 32 supported LinkUp LUs (provided
you have configured all of them as valid in your application).
Conversely, a logical unit and an asynchronous port are said to be decoupled when a physical or logical
disconnection occurs between the attached ASCII device and the LinkUp. For example, the LU and port
are decoupled when your communi-cation line drops, or when the LinkUp times out after the
configured Inactivity Time Limit is reached. If a logical unit and an asynchronous port are decoupled,
then the formerly coupled LU can be accessed from another physical port; or another LU can be
coupled at the same physical port. In Figure 3-2, several diagrams a provided to show these various LUport coupling options.
NOTE
Establishing a communication link with your System/3X host for each of these LUs
means you must define a workstation identification number (also called a local session
ID or LSID), recognized as viable by your host, to each LinkUp LU. This is done by
entering your host’s LSID to the LinkUp configuration parameter of Local Station
Address.

The virtual device addressing concept also enables the LinkUp to support its Auxiliary Printer facility.
Once the appropriate configurations are made in the LinkUp, a terminal connected to an asynchronous
port can sign on to the LinkUp (at Connect Mode), specify an LU associated with an auxiliary printer
LU, and have both devices supported on that single port. See Figure 3-3 for a diagram of this feature.
Figure 3-3. Dual LU to Single Physical Port Coupling.
3.4 User-Friendly Facilities
The LinkUp is designed to be user-friendly. You should have very little, if any, difficulty operating it.
Here are some of the facilities that make the LinkUp 5294 easier to operate:
• A Menu-Driven Configurator Mode, enabling you to define a variety of operational parameters
by menu selections. These define the operating characteristics of the LinkUp’s synchronous
and asynchronous ports, logical units, and attached devices.
• Help Messages are available at each of the LinkUp operating mode menu prompts (including
Connect, Configurator, and Setup) whenever you type a <?> in response to the prompt.
• Non-volatile Electrically Erasable PROM (EEPROM) storage of every parameter value you define in
Configurator Mode. This enables the LinkUp to retain your configured values even when its power
is turned off.
• Password protection for Configurator Mode, preventing anyone from accessing it and redefining the
LinkUp parameter values unless authorized with the correct password.
• Operating and Channel Status Indicators on the front panel of the LinkUp unit. These let you
monitor your unit’s overall system health and the crucial RS-232C line signals for any port.
• Self-testing performed continuously in the background throughout daily operations. This assures you
that the LinkUp is effectively executing its operating programs.
• Automatic baud detection lets the LinkUp automatically detect the incoming baud (or bit) rate of
the device you have attached to its asynchronous port.
• An Inactivity Time Limit can be set in Configurator Mode. This enables you to define a maximum
amount of time for the LinkUp to maintain the coupling between your terminal, while it is inactive,
and its associated LU session.
• A Reconnect Time Limit can also be set in Configurator Mode. This time limit enables the LinkUp to
maintain the coupling between a disconnected terminal and its associated LU session. It lets you
reconnect and pick up from where the session was interrupted.
• Two-level password protection can be defined for each LinkUp LU whenever you define a Connect
Mode password in Configurator Mode. The first level allows the LinkUp to restrict access to an LU
from everyone except the one authorized with the correct password. The second one limits access to
an interrupted LU session from everyone except the one who initially established the session.

3.5 File-Transfer Support
The LinkUp can support file transfers between a System/3X host computer and an ASCII micro, mini,
or instrumentation computer, providing the appropriate host and ASCII computer communication and
transfer programs are installed. If the ASCII computer is an IBM Personal Computer (or compatible),
four software package combinations currently available in the market can be used with the LinkUp:
• FileLynx
®
/5251 PC* and Emulator Transfer Utility by SSI
• TruLynx
®
/5251 PC and Emulator Transfer Utility by SSI
• TruLynx/5251 PC and Emulator Transfer Utility by IBM
• TruLynx/5251 PC and PC Support by IBM
*FileLynx/5251 PC can also transfer files without the assistance of a host package by a simple screen-byscreen process. Consult your supplier for more information on the various capabilities of this software
package.
NOTE
PC Support/400 is not supported on the LinkUp 5294.
However, if the ASCII computer is not IBM compatible, you must provide your own communication and
transfer programs for both your 3X host and the ASCII computer. In support of such an application, the
LinkUp 5294 provides the COMPU Terminal Module. COMPU was designed especially for a computerto-computer transfer, and as such differs from the other Terminal Modules in the following ways:
1. Data alone is transmitted; for example, no intensity or cursor-positioning sequences are ever sent,
even if your 3X host requests them. This process enables the LinkUp 5294 to convert and pass on
the transferred data in the same order it was received.
2. Screen optimization is not performed; instead, the LinkUp completely updates a screen full of data
each time an update is required. (Usually, the LinkUp updates a screen of data by repainting only
the new data and clearing any old data not similar to the new data.)
3. Transferred data is completely buffered by the LinkUp 5294, enabling a continuous transmission of
data. Typically the 3X host inhibits transmission when it is processing received data by inhibiting
your keyboard input; normally, the LinkUp 5294 adheres to this procedure and ignores any
keyboard input you attempt.
NOTE
The COMPU module relies on the normal ASCII-to-EBCDIC and EBCDIC-to-ASCII
translations of the data handled by the LinkUp. Additionally, the key sequences defined
for its emulation keyboard functions are identical to those used for the ADM3A Terminal
Module.

3.6 Modify for 3174 Protocol
The DL5294 Firmware (PCM91) differs from the STD 3174 Firmware (PCM92) in the following aspects
only:
• PROM cartridge (the installed firmware)
• Internal EEPROM format
• Amount of RAM installed
• Silkscreened name on front panel of unit
Your LinkUp 5294 with DL5294 Firmware can be modified to support the 3174 protocol by doing the
following:
• Ordering the appropriate conversion kit from your supplier.
• Replacing and/or installing the respective parts (in accordance with the kit’s provided instructions).
• Invoking Setup Mode (explained in Section 7.7).
3.7 Port Test and System Management Modes
These two modes perform a variety of valuable diagnostic and information functions. Port Test Mode
consists of the following:
• Interface Signal Display (your port only)
• Character Display Test
• Character Echo Test
System Management Mode consists of the following:
• Interface Signal Display (any LinkUp 5294 port)
• Sync Port Address Trace
• Async Port Trace
• Product Configuration and Levels display
• Sync Port Trace
• Character Display Test (the same as in Port Test Mode)
• Character Echo Test (the same as in Port Test Mode)
• LU and Async Port Summary
• Remote Reset
• SNA/SDLC Counters
Port Test Mode is covered in Section 7.3. System Management Mode is covered in Section 7.4.
CHAPTER 3: Features and Applications

3.8 5251/5294/5394 Emulation
With 5251, 5294, and 5394 controller emulation, the LinkUp 5294 can be configured to emulate two
different controllers concurrently on the LinkUp 5294’s two synchronous ports. In other words, both
ports can be configured to emulate either a 5251 Model 12 or a 5294 or 5394 controller, or one port
can be configured to emulate a 5251 Model 12 while the other emulates either a 5294 or 5394.
NOTE
Some capabilities of an actual 5294 or 5394 controller are not fully supported by the
LinkUp 5294. For example, Text Assist is not implemented; therefore, DisplayWrite is
not supported. Consult your supplier for more information on those capabilities not
supported.
3.9 Additional Features
• The LinkUp 5294 can be programmed for up to four controller emulations on one synchronous port
(or a maximum of four across the two synchronous ports).
• Five additional functions in System Management Mode (see Section 3.7 above for a description).
• 5394 Controller emulation.
When the capability of Four Controller Emulations Per One Synchronous Port is implemented, the
LinkUp 5294 appears to your host as if it were up to four distinct controllers (each with its own
System/3X controller address) on a multipoint line. The LinkUp 5294 supports this facility by mapping
each of the 3X controller addresses to the appropriate controller emulations by a logically defined Link
Station Address (identified as Links 0, 1, 2, and 3). If so configured, the LinkUp 5294 can emulate as
many as four distinct controllers across its two synchronous ports, in any combination (four addresses on
one port and none on the other, or three on one port and one on the other, etc.). See Section 7.5.
Operating a single LinkUp 5294 as multiple controllers requires that you divide the virtual device
addresses (logical units) among the controllers (identified as link station addresses). If your application
uses this capability, keep the following limitations in mind:
1. An IBM System/3X will activate at most nine logical units when connected to a 5251 Model 12
controller, only eight logical units when connected to a 5294 controller, or as many as 16 logical
units when connected to a 5394 controller.
2. The LinkUp 5294 can emulate up to four controllers simultaneously; those four may be a mix of
5251-12, 5294, and 5394 emulations.
3. Because it has a maximum of 32 logical units available, the LinkUp 5294 can have attached and
active at most 32 of the 36 logical units (nine LUs per controller times four 5251-12 controllers)
available to your host(s) if emulating 5251-12 controllers. Similarly, only 32 of the possible 64 logical
units (sixteen LUs per controller times four 5394 controllers) may be active during 5394 emulation.
When emulating 5294 controllers, the LinkUp can have all 32 of the host’s logical units attached and
active.

4. Hardware Overview
This chapter discusses the LinkUp 5294’s hardware components and capabilities.
4.1 Front Panel
The front panel of the LinkUp 5294 is shown in Figure 4-1. Status indicators monitor power and RS232C line signals on the selected channel. Two user controls are provided for easy operation.
Figure 4-1. LinkUp 5294 Front Panel.
4.2 Front Panel Controls
Two front panel controls are provided on the LinkUp 5294: the CH SEL button and the RESET button.
Each of these controls is discussed below.
• CH SEL (Channel Select) Button — The CH SEL button is used to select the channel to be
monitored. When the button is pressed, the channel number increases. When held for a longer time,
the channel number is incremented at a faster rate. The channel being currently monitored is
indicated by the two-digit LED display.
If the channel number is incremented past the highest channel available in the unit, 88 appears in
the display and an LED integrity test is performed. All of the front panel lights are turned on to
ensure proper operation. Pressing the CH SEL button again terminates the LED test.
• The RESET Button — The RESET button is used to clear error codes from the front panel display.
Error codes are listed in of Section 9.1. When the first error occurs, pressing RESET clears the error
and channel status display resumes. If there is more than one error, the RESET button clears the
most recent error and displays the previous one. When all of the accumulated errors have been
displayed and cleared, the status lights resume their normal function. Once cleared, errors cannot be
redisplayed using the front panel. Therefore, you should write down any error codes that are
displayed before you press RESET.

4.3 Channel Status Indicators
The LinkUp 5294 is equipped with a full RS-232C status display capable of monitoring the status of any
selected port. Each of the indicators is briefly described below. ON indicates that the LinkUp 5294 is
either transmitting or receiving the signal as appropriate.
• DCE/DTE (Data Communications Equipment/Data Terminal Equipment) — An LED lit for one of
these indicates that the port selected has been software-optioned to communicate with either a
modem (DTE) or directly to a terminal or printer (DCE).
• TXD/RXD (Transmit Data/Receive Data) — These are data signals that indicate transmission of data
either to or from the LinkUp 5294.
• RTS (Request to Send) — The LinkUp 5294 provides this signal when optioned as DTE or when it
expects to receive the signal when optioned as DCE.
• CTS (Clear To Send) — The LinkUp 5294 provides this signal when optioned as DCE and expects it
from the modem when optioned as DTE.
• DTR (Data Terminal Ready) — The LinkUp 5294 provides this signal when optioned as DTE or
expects to receive the signal when optioned as DCE. Additionally, when configured as DTE autoanswer, this signal will be provided only after receipt of the Rl (Ring Indicator) signal from the
modem.
• DSR (Data Set Ready) — The LinkUp 5294 provides this signal when optioned as DCE or expects to
receive it from the modem when optioned as DTE.
• CD (Carrier Detect) — This LED is lit when the LinkUp 5294 has detected a carrier signal from a
remote modem. If no detectable carrier signal is present, or the remote modem hangs up, this LED
is turned off.
• RI/SYN (Ring Indicator/Data Sync) — This is a dual-function LED. It displays Ring Indicate when
the selected port is optioned as DTE/auto-answer in synchronous or asynchronous operation. On
the sync port, this LED is always off.
• TXC/RXC (Transmit Clock/Receive Clock) — When on, this LED indicates the presence of
synchronous clock signals which are required for the sync port. These must always be present for
Port 0 and Port 1.
• I/O FAULT — On SYNC ports, this LED flashes if a framing error occurs. On asynchronous ports
this LED indicates parity errors.
During normal operation in async DTE mode, the following should be on:
DTE, RTS, CTS, DSR and CD
RI will be on during ringing, and DTR will come on after RI is detected.
During normal operation in async DCE mode, the following should be on:
DCE, RTS, CTS, DTR, DSR and CD
In both DTE and DCE modes, the TXD and RXD lights will blink during data transfer.

4.4 System Status Indicators
The following system status indicators are provided on the front panel.
• SYS OK — This LED blinks to indicate that the system is functioning properly. The LED acts as a
“heartbeat” indicator and is never turned off unless there is an unrecoverable error.
• ON — When on, this LED indicates that the power supply is functioning properly.
4.5 Error Code Display
When a program-detectable error occurs , all channel status indicators are turned off and a two-level
error code is displayed using the two-digit channel display. The two error codes are flashed alternately.
4.6 Rear Panel
The rear panel of the LinkUp 5294 is equipped with the following:
1.Up to 34 serial (RS-232/V.24 compatible) Ports, numbered 0 through 33.
2.An A.19/.15, 50/60 Hz air flow fan.
3.A rocker-type on/off power switch.
4.A 1-amp, 250-volt fuse just below the power switch (which can be removed by sliding out the rubber
fuse cartridge with a screwdriver).
5.A power cord receptacle (below the fuse).

5. Electrical Characteristics
This chapter covers the power specifications of the LinkUp 5294 and the requirements of the
RS-232C interface for synchronous and asynchronous communications.
5.1 Power Specifications
The LinkUp 5294 power supply is rated at 50 watts and operates on 115 or 230 volts (plus or minus 15%)
at 50 or 60 Hz (plus or minus 2 Hz). Its power connector is the international standard CEE-22.
NOTE
Units with 115 volts are shipped with a 7-foot NEMA 5-15P three-prong plug.
The LinkUp 5294 is certified to operate in accordance with the following standards:
• UL — Underwriters Laboratory: Listed with EDP Equipment/Office (Standards 478), File No.
E87479.
• CSA — Canadian Standards Association: Certified.
• IEC — International Electrotechnical Commission: Designed to meet IEC 380.
• BPO — British Post Office: Meets the requirements of Technical Guide #26.
• FCC — Federal Communications Commission: Complies with the requirements of U.S. 47CFR Part
15 Subpart J, Class B, assuming shielded RS-232C cables are used.
5.2 Cable Pin Requirements
All of the ports on the LinkUp 5294 support the standard EIA RS-232C interface signals. In the next
three sections, the signals specific to synchronous and asynchronous communications are identified.
Synchronous Port
A minimum conductor synchronous cable that will work with Bell compatible sync modems and the
LinkUp 5294 in Modem Eliminator mode requires the following pins: 1 through 8, 15, 17, and 20. If the

CHAPTER 6: Installation

6. Installation
This chapter describes installation of the LinkUp 5294. A typical local installation to a single host is
described. Attachment of local and remote (to the LinkUp 5294) terminals and printers is also included
in Sections 6.3, 6.4, and 6.5. Special considerations for dual host and remote host environments are
described in Section 6.6.
Information regarding the configuration of the communication and work station parameters for
the System/36 and the System/38 is given in Appendices E and F, respectively, of this manual.
6.1Installing the LinkUp 5294 and the Configuration Terminal
Configuration and installation of the LinkUp 5294 requires attachment of an asynchronous terminal
to one of the asynchronous ports. The terminal is then used in conjunction with the Configurator menus
to set the logical configuration parameters. The terminal used for this purpose is referred to as the
Configuration Terminal throughout this section.
We recommend that a local terminal be used for initial installation and configuration. This will simplify
problem isolation during the installation process. Therefore, the following sections assume that the
configuration terminal will be locally attached to the LinkUp 5294. If a remote terminal must be used,
see Section 6.4.
6.1.1 U
NPACK THE LINKUP 5294
The LinkUp 5294 is carefully packed in a 25.5" x 15.8" x 11" box. A label on the outside of the box lists
the model of the unit, serial number, firmware version number, date of manufacture, voltage setting of
the power switch (115 or 230 VAC), and other electrical information. Inside you will find a a release
