INDEX ...................................................................................................................................................................... 76
VERY IMPORTANT!!! Determine what type of TX102, TX104, or
TX108 you have purchased. There are two different types of Telplex:
multi-drop (Rev. 3.03) and standard (Rev. 1.04). Multi-drop units are
identified by a TYPE A sticker on the rear panel. Standard units do
not have a TYPE A sticker. Certain parts of this manual will pertain
only to a multi-drop unit and not the standard unit or vice versa. You
will be instructed to disregard certain parts of this manual if the
corresponding information is not relevant to a specific type of Telplex.
The Telplex TX102, TX104 and TX108 statistical multiplexer (stat
mux) units are used to link EIA-232 serial devices (e.g., computers,
terminals and printers) located at multiple sites together over single
telephone lines or cables. Such devices are connected to terminal
ports on the Telplex. A local TX102, TX104, or TX108 is connected to
a remote Telplex via a composite port.
The remote Telplex may be a TX102, TX104, TX108, TX4, TX28, or
TX60 for multi-drop units. The TX28 and TX60 are expandable units
that may have up to twenty-eight and sixty terminal ports respectively.
The TX28 and TX60 may have multiple composite ports installed to
allow connections to multiple sites. A standard TX102, TX104, or
TX108 will connect to an identical unit at the remote site.
The TX102, TX104, or TX108 will multiplex two, four, or eight lines of
data respectively. The multiplexed data is sent sequentially over a
single telephone line or cable via the local unit's composite port. The
data is automatically demultiplexed by a remote Telplex with
distribution of data to designated terminal ports.
A Telplex pair may be used in a "point-to-point" application where up
to two, four, or eight separate lines of data may be multiplexed and
demultiplexed simultaneously between two sites as shown in Figure 1.
The Telplex TX104
and TX108 multiplex
four or eight individual
communications lines
into a single
composite channel.
These statistical
multiplexers can be
used with existing
modems, short haul
modems, or hardwired back-to-back to
suit your specific
requirements
Figure 1
In this example, Port 1 of Unit 1 communicates with Port 1 of Unit 2,
Port 2 of Unit 1 communicates with Port 2 of Unit 2 and so on.
NOTE: Standard units will support point-to-point applications only.
A multi-drop application involving multiple composite ports will connect
several units to a TX60 or TX28 in a "star" configuration. See Figure
2 on the following page.
Figure 2
Individual Telplex models are self-contained devices which can be
desk-top or rack mounted. The baud rate, word size, stop bits, parity,
XON/XOFF handshaking and RTS/DSR pass through for all terminal
ports are programmable. Other programmable features for the
terminal ports include Block Size, Local Access, and Status
Messages. Serial Port Destination and Unit Number are
programmable for multi-drop units. Programmable features for the
composite port include the baud rate, Line Type, and Programmable
Strings. All changes are saved in non-volatile memory to become the
new power-up default.
Multi-drop units operate in one of seven modes: System mode, MUX
mode, Local Unit Configuration mode, Remote Unit Configuration
mode, Local Diagnostics mode, Remote Diagnostics mode, or
Access Local Modem mode. Standard units operate in one of four
modes: Local mode, MUX mode, Local Unit Configuration mode,
or Remote Unit Configuration mode.
System mode (multi-drop units) and Local mode (standard units)
allow a local terminal to instruct the Telplex to enter into any of the
other modes of operation. Either type of unit communicates in MUX
mode when a successful connection has been made with a remote
Telplex. While in MUX mode, terminal ports on the local Telplex
communicate with designated terminal ports on a remote Telplex.
Local Unit Configuration mode allows a local terminal to program
the various features on the local Telplex. Remote Unit
Configuration mode allows this same terminal to program these
features on a remote Telplex model when a communication link is
established with the remote site.
In Local Diagnostics mode, a terminal connected to a multi-drop unit
may instruct the local Telplex to perform a self-test on all ports. The
terminal may also communicate in full duplex or loopback
communication with a selected port on the local unit. Remote
Diagnostics mode allows a terminal connected to a multi-drop unit or
a standard unit to perform self-test, full duplex, or loopback
Diagnostics with ports on a remote Telplex if there is a communication
link. Standard units allow remote unit diagnostics from Remote Unit
Configuration mode.
Access Local Modem mode allows a terminal connected to a multidrop unit to communicate directly with the composite port and issue
commands to the local modem. This device may also instruct the
Telplex to send two separate user-programmable strings to the local
modem. A terminal connected to a standard unit may perform
modem communication from Local mode.

This section discusses basic installation instructions pertaining to
unpacking your Telplex, obtaining the software from the supplied
diskette, power considerations, factory default parameters and
composite/terminal port cabling. Operation is described in Section 4,
Section 5 discusses configuration and Section 6 provides specific
configuration examples.
After opening the box, check the packing list that comes with your
Telplex to ensure that you have received all components. At a
minimum you should have received the unit, this manual and any
applicable addendums, and a software utility diskette. The TX102 will
be provided with an external power supply. Check the unit to make
certain it did not incur damage during shipping. If items are missing or
damaged, contact BayTech technical support at 800-523-2702.
BayTech provides utility software for DOS compatible PCs to assist
you in configuring the Telplex.
IMPORTANT: Copy the BayTech original diskette onto a blank
diskette and store the original in a safe place.
The diskette contains the following programs: REMCONFG.COD,
SMODE.EXE, TERM.EXE and README.RDM. The Telplex does not
utilize the REMCONFG.COD file. TERM.EXE is a terminal emulation
program used to configure the various features of the unit.
SMODE.EXE is a program used to configure COM ports of DOS
compatible machines to operate at speeds faster than 9600 bps (up to
115,200 bps).
Please review the README.RDM file to obtain instructions for
TERM.EXE and SMODE.EXE. To view the README.RDM file on
your screen, first insert the diskette into your PC's disk drive and then
enter the command TYPE README.RDM from your disk drive
prompt. To print this file, enter the command
COPY README.RDM LPT1: from your disk drive prompt.
The TX104 and TX108 require 115 VAC, 50/60 Hz power and come
with a three-prong power cord. Do not attempt to operate the unit with
a two-prong socket or adapter. 230 VAC, 50/60 Hz is optional.
The TX102 requires external DC power. Plug the DC jack of the
external power supply into the 9VDC receptacle on the back of the
unit. Plug the AC connector into an AC outlet.
All Telplex models power up when you press the power switch to
"ON". A green LED on the front panel will illuminate when power is
applied.
CAUTION: Do not attempt to make any internal changes. Any
upgrades to the main board EPROM must be performed by an
authorized service technician or by BayTech. Please contact
BayTech at 1-800-523-2702 for more information.

If your application does not match this factory setup, you must
reconfigure your Telplex as described in Section 5.
The composite ports of multiple Telplex units are connected together
via external modems (Section 3.5.1) or cable (Section 3.5.2).
See Section 3.5.1.1 if connecting a modem to a TX104 or TX108 or
Section 3.5.1.2 if connecting a modem to a TX102.
If an external modem will be used to connect a local TX104 or TX108
to a remote Telplex, the modem should be connected to the
COMPOSITE EIA-232 port on the back panel of the unit (see
Appendix B). The TX104 or TX108 should be programmed to operate
with a Line Type of Modem (see Section 5.8).
The standard configuration of the COMPOSITE EIA-232 port is DTE

You may issue commands to the external modem from selected
terminal devices when the Telplex is in Access Local Modem mode.
Please see the technical documentation for your modem to determine
which commands are supported.
WARNING: XON/XOFF flow control must be disabled on the
modems. Failure to do so will result in erroneous characters
appearing in addition to the data being sent.
The modem should be connected to the COMPOSITE EIA-232 port on the
back panel of the TX102 and the unit programmed to operate with a Line
Type of Modem (see Section 5.8). The TX102 composite port has an RJ-45
modular connector. Most modems do not have RJ-45 modular connectors.
Therefore, adapters are required to convert the modem's DB-25 connector
to a module connector. BayTech has a complete line of RJ-45 adapters that
will make your installation quick and trouble free. See Appendix A.4 for the
recommended adapter/cable pinouts. Figure 4 and Figure 5 are drawings of
an RJ-45 receptacle and plug. The pin assignments are given.

NOTE: The EIA-422 port will give you the capability of using a cable
up to 4000 feet between two Telplex units.
If you wish to connect the composite port of a local TX102 to a remote
Telplex via cable, use the COMPOSITE EIA-232 port on the back
panel of the TX102. You must program the unit to use a Line Type of
Direct (see Section 5.8). See Section 3.5.1.2 for the pin/signal
definition of the composite port.
IMPORTANT: When connecting a TX102 to a remote Telplex via
cable, you must use the EIA-232 composite port on the remote unit.
This port is usually connected to an external modem. Do not use the
EIA-422 port on the remote unit.
Some remote Telplex models will require an RJ-45 adapter to convert
the EIA-232 composite port's DB-25 connector to an RJ-45 connector.
The following Telplex models require an adapter to connect to the
TX102 via cable: TX104, TX108, and TX24-V41B module. The
adapter required for these models is 25FRJ45PC-1. The pinout for
this adapter and the required cable are shown in Appendix A.4.4.
WARNING: Do not use a cable longer than 150 feet to connect the
TX102 to a remote Telplex.
If connecting a terminal device to a TX104 or TX108, refer to Section
3.6.1. Refer to Section 3.6.2 if connecting to a TX102.
IMPORTANT: Before you proceed with cabling, you must know
whether the terminal devices that you will connect to your Telplex are
DTE (Data Terminal Equipment) or DCE (Data Communication
Equipment). The following devices are generally DTE: terminals,
printers, and computers like the IBM PC. The following devices are
DCE: modems and some computers.
The standard configuration of the TX104 and TX108 is all terminal
ports DCE with DB-25 female connectors. DCE ports use the
following signals for communication:

NOTE: Please refer to Appendix A for recommended cabling
between the TX104 or TX108 and various computers and printers.
The terminal ports on the TX102 have RJ-45 module connectors.
Most serial computers, terminals, and printers do not have RJ-45
modular connectors. Therefore, adapters are required to convert
either DB-25 or DE-9 connectors to modular connectors. BayTech
has a complete line of RJ-45 adapters and cables that will make your
installation quick and trouble free. The TX102's terminal port use the

Section 4.1 discusses terminal port operation, Section 4.2 discusses
composite port operation, Section 4.3 discusses the different
operating modes, Sections 4.4 and 4.5 discusses the LEDs and
SELECT switch functions, and Section 4.6 discusses data flow
control.
The TX102, TX104, and TX108 multiplex two, four, or eight lines of
data respectively. Multiplexed data is sent sequentially over a single
telephone communication line or cable. Data is then automatically
demultiplexed by a remote Telplex with distribution of data to
designated terminal ports. Individual terminal ports may be
programmed to allow the device connected to it access to System
mode for multi-drop units or Local mode for standard units.
NOTE: Standard units will only support a "point-to-point" application
as shown in Figure 1 on Page 2. Port 1 of the local unit will
communicate with Port 1 of the remote unit, Port 2 with Port 2, and so
on. Multi-drop units allow you to program the specific remote port a
local terminal port will communicate with once both units go into MUX
mode.
!
You may program the baud rate, word size, stop bits, parity,
XON/XOFF handshaking and RTS/DSR pass through for individual
terminal ports. Please see Section 2 for a list of available serial
parameters. The Telplex will translate for devices using different
configurations. The factory default Serial Port Configuration is
9600 baud, 8 bit word size, 1 stop bit, no parity, XON/XOFF
handshaking and RTS/DSR pass through disabled for all ports.
"
Multiplexed data from individual terminal ports is sent and received by
the composite port in blocks. The Block Size for individual terminal
ports may be programmed from 1 to 255 characters. If a terminal port
requires a higher priority, the port would have a larger Block Size than
the other terminal ports. For example, if a port on a main frame
computer system is primarily sending data to a remote terminal, the
main frame port could be programmed to have a higher data block
size.
NOTE: It is recommended that the transmit Block Size for a particular
terminal port be no less than 10 characters due to resulting
performance degradation.
The default Block Size is 32 characters for all ports.
The Telplex may be programmed to allow selected terminal devices to
enter into System mode. Entry into System mode allows selected
users to instruct the Telplex to enter into any of the other modes of
operation (see Section 4.3). The factory default Local Access is
enabled for Port 1 and disabled for all other ports.
Status messages are sent to selected terminal ports under various
conditions. These messages inform the terminal port(s) if the local
Telplex is waiting for a connection or has a connection with its
designated remote port. Another status message will prompt terminal
ports with Local Access enabled to send +++ to enter into System
mode or Local mode (see Section 4.3.1).
NOTE: Terminal ports with Status Messages disabled will not receive
any of the messages shown in the following illustrations.
A standard unit will send a message similar to the following for a
TX104 when the Telplex is powered up and when MUX mode is
terminated (see Section 4.3.3):
TX104 in Local mode --- Type +++ to Access Local Mode
When a standard unit enters into MUX mode, the Telplex will send the
following message:
TX104 in MUX mode
A multi-drop unit will send the following message when the Telplex is
powered up and when returning to MUX mode from System mode
(see Section 4.3.1):
TELPLEX IN MUX MODE
Type +++ to Access System Menu
While a local terminal port on a multi-drop unit is waiting for a
connection to its designated remote terminal port, the following
message will be sent:
Waiting for Connection!
After a connection is made, the following message will be sent from a
multi-drop unit:
Connect To Unit X, Module Y, Port Z
where X is the designated unit number, Y is the designated module
number and Z is the designated port number (see Section 4.1.2.5).
If a multi-drop unit has a connection with its designated remote
Telplex and the connection is terminated, the Telplex will send the
following message:
Port Disconnected
Status messages will also be generated when a local terminal enters
into System/Local mode (see Section 4.3.1) or Diagnostics mode (see
Section 4.3.4).
The factory default has Status Messages enabled for Port 1 and
disabled for all other ports.
NOTE: This section does not apply to standard Telplex units.
Serial Port Destination is the remote Telplex terminal port a local
terminal port will connect to once a communication link is established.
The Serial Port Destination consists of the remote Telplex's Unit
Number, Module Number and Port Number. The Unit Number may
range from 1 to 32, the Module Number may range from 1 to 16 and
the Port Number may range from 1 to 8.
Factory default is Unit 1, Module 1, Port X, where X is the local
unit port number (1 to 8).
NOTE: This section applies to multi-drop units only.
Unit Number is used to identify multiple Telplex units and to direct
terminal port data. Unit Number informs a local Telplex that data
coming in from a remote unit is to be routed to a local port. If a
remote terminal port is to communicate with a local terminal port, the
remote terminal port would have the local Unit Number as part of its
Serial Port Destination. The Telplex Unit Number may range from 1
to 32. Factory default is Unit 1.
Data transfer between a local and remote Telplex is accomplished via
each respective unit's composite port. Each unit generates and traps
internal commands used to transmit and receive terminal port data
over the composite link. These internal commands are stripped out of
the data stream and are not seen by the terminal ports. This makes
the data flow between respective terminal ports totally transparent.
!
The baud rate for certain composite ports may be programmed to
operate at various speeds as listed in Section 2 (Specifications).
The default baud rate is 9600 bps.
The local Telplex can communicate with a remote Telplex connected
together via external modems or via cable. If you intend to connect
the Telplex units together via modem, you must choose the Line Type
to be Modem. If you intend to connect the Telplex units together via
cable, you must choose the Line Type to Direct.
NOTE: Choosing Modem Line Type on the Telplex does not
configure the external modem to operate using dial-up or leased lines.
You must configure the modem separately to use the appropriate line
type.
If you configure your external modem to use leased lines and are
using Hayes compatible modems, the local modem should be
programmed to operate using either auto originate (ATO) or auto
answer (ATA) and the remote modem should be programmed to
operate using either auto answer or auto originate respectively. You
can program the Telplex to send out the auto originate or auto answer
AT commands to the external modem upon power-up , loss of DCD,
or manually using the Programmable Strings (see Section 4.2.2.3).
The factory default Line Type is Direct.
NOTE: This feature is applicable only if the Telplex is programmed to
use Modem Line Type.
The Telplex can be programmed to automatically send two separate
character strings up to 42 characters in length to the composite port.
Either string may be programmed to be sent on power-up, when
carrier drops out, on a combination of power-up or loss of carrier, or
manually only. Either string may be sent manually regardless of the
condition you choose. String 1 is sent manually by typing Control-U
while in Access Modem Command mode for multi-drop units (see
Section 4.3.5) or Local mode for standard units (see Section 4.3.1)
and String 2 is sent manually by typing Control-V.
Programmable Strings typically consist of modem commands (e.g., to
instruct the local modem to dial out to a remote Telplex). If the string
consists of a dial command and a connection is made with the remote
Telplex, both units will go in MUX mode (see Section 4.3.3).
The default Programmable Strings are String 1 and String 2 both
null. The default sending condition is manual for both String 1
(Control-U) and String 2 (Control-V).
There are seven operating modes for multi-drop units: System mode,
Local Unit Configuration mode, Remote Unit Configuration mode,
MUX mode, Local Diagnostics mode, Remote Diagnostics mode, and
Access Local Modem mode. There are four operating modes for
standard units: Local mode, MUX mode, Local Unit Configuration
mode, and Remote Unit Configuration mode. Sections 4.3.1 through
4.3.5 describe each operating mode in detail.
NOTE: System mode applies to multi-drop units and Local mode
applies to standard units. However, both modes are similar.
System/Local mode allows a terminal to instruct the Telplex to go into
any of the other operating modes. You must access System/Local
mode in order to access any of the other modes except MUX mode
(see Section 4.3.3). System/Local mode is accessed from a terminal
port with Local Access enabled by issuing the Escape Code
Sequence which consists of a one second delay followed by +++ and
another one second delay. The terminal that has accessed System
mode will be referred to as the active terminal.
Multi-drop Units: System Mode
Once a terminal connected to a multi-drop unit has accessed System
mode, the Telplex will send back the System Menu similar to the
following for a TX104:
TELPLEX TX104 System Menu
Local Unit Configuration......1
Remote Unit Configuration.....2
Mux Mode......................3
Local Diagnostics.............4
Remote Diagnostics............5
Access Local Modem............6
Enter Request:
NOTE: Item "6" (Access Local Modem) will appear in the System
Menu only when using Modem Line Type. If using Modem Line Type
and the Telplex enters System mode, the unit will send +++ to the
external modem which will put the modem into command mode. The
Telplex will send ATO to the local modem when you type "3" (Mux
Mode) from the System Menu. This will instruct the local modem to
return to data mode.
Type "1" to enter Local Unit Configuration mode, "2" to enter Remote
Unit Configuration mode, "3" to enter MUX mode, "4" to enter Local
Diagnostics mode, "5" to enter Remote Diagnostics mode, or "6" to
enter Access Local Modem mode. The Telplex will return to System
mode when exiting Local/Remote Unit Configuration mode or
Diagnostics mode.
If System mode is currently accessed by another terminal port, the
Telplex will send the following message:
System Menu Currently Being Accessed by another Port
Standard Units: Local Mode
Once a terminal connected to a standard unit has accessed Local
mode, the Telplex will send back the Local Mode menu as follows:
LOCAL MODE
Type Ctrl C
Type Ctrl T
Type Ctrl R
Type Ctrl P
Type Ctrl U
Type Ctrl V
for Mux Mode
for Local Configuration
for Remote Configuration
or +++ for Modem Command
to Send String 1
to Send String 2
NOTE: The last three items of this menu will appear in the Local
Mode menu only when using Modem Line Type. Communication with
an external modem is done from this menu. If you wish to issue
commands to the local modem, you must first instruct the modem to
go into command mode by either typing Control-P or +++. If you wish
to return to MUX mode, first type Control-P followed by Control-C.
The Telplex receives Control-C, it will sent the ATO command to the
external modem to instruct the modem to return to data mode.
If Local mode is currently accessed by another terminal port, the
Telplex will send the following message:
Local Mode Currently Being Accessed by another Port
Local and Remote Unit Configuration mode are used to program the
various features of the local Telplex or a remote unit. For multi-drop
units, Local Unit Configuration mode is accessed by typing "1" from
the System Menu and Remote Unit Configuation mode is accessed by
typing "2" from this menu. For standard units, Local Unit
Configuration mode is accessed by typing Control-T from the Local
Mode menu and Remote Unit Configuration mode is accessed by
typing Control-R from this menu.
NOTE: The active terminal may access Remote Unit Configuration
mode only if there is a communication link established with the
desired remote Telplex. The active terminal cannot change any
features of the remote unit's composite port since this would disrupt
the communication link.
Programmable features for the terminal ports include serial port
configuration, Data Block Size, and Status Messages. Serial Port
Destination and Unit Number are programmable for multi-drop units
only. Programmable features for a local composite port include baud
rate, Line Type, Programmable Strings and Multiple Unit
Configuration.
Section 5 provides a detailed description of how the local Telplex or a
remote unit is programmed while in Local Unit or Remote Unit
Configuration mode.
In MUX mode, the local Telplex is connected to a remote unit via the
composite link and respective terminal devices are able to
communicate back and forth. Data received on a local terminal port is
transmitted to the designated remote terminal port and vice versa.
MUX mode is accessed in a number of ways depending on the Line
Type you are using (Modem or Direct).
When using Modem Line Type, the Telplex will go into MUX mode
when the composite port receives a low to high transition (negative to
positive voltage) on the DCD line or a CONNECT message from the
modem. The Telplex will also go into MUX mode when instructed to
do so manually if there is an existing communication link with the
remote site. An active terminal connected to a multi-drop unit may
instruct the Telplex to go to MUX mode by typing "3" from the System
menu. An active terminal connected to a standard unit may instruct
the Telplex to go to MUX mode by typing Control-C from the Local
Mode menu. The Telplex will stay in MUX mode until the carrier (DCD
or phone line) drops out. MUX mode will also be terminated when a
local terminal instructs the Telplex to go into Local or Remote Unit
Configuration or Diagnostics mode.
If using Direct Line Type, the local Telplex will go into MUX mode
automatically upon power-up once the local composite port
recognizes a connection with the designated remote Telplex. The
Telplex will also go into MUX mode when the active terminal instructs
the Telplex to go into MUX mode manually from the System Menu for
multi-drop units or from the Local Mode menu for standard units as
described in the previous paragraph (assuming there is an existing
communication link with the remote site). The Telplex will stay in
MUX mode until the Escape Code Sequence is received by a local
terminal with Local Access enabled.
NOTE: Standard units support Remote Diagnostics mode only.
Diagnostics mode allows the active terminal to perform various tests
with a remote Telplex unit if a communication link is established.
Multi-drop units also allow the same tests to be performed on the local
unit. The active terminal may communicate individually with any port
on a remote Telplex or the local unit (multi-drop units only) or perform
a self test on all ports.
The full duplex diagnostic tests a selected port's ability to transmit and
receive data. Any data received by the active terminal port will be
transmitted out the selected port and vice versa. The loopback
diagnostic allows the active terminal to have all data typed on the
keyboard echoed back to the terminal screen by the selected port.
The self test diagnostic checks various internal components for all
ports on the Telplex.
Section 4.3.4.1 describes Local Unit and Remote Unit Diagnostics
mode for multi-drop units and Section 4.3.4.2 describes Remote Unit
Diagnostics mode for standard units.
!
To enter into Local Diagnostics mode, type "4" from the System Menu
(see Section 4.3.1). To enter into Remote Diagnostics mode, type "5"
from the System Menu. For example, if you type "4" for Local
Diagnostics, the Telplex will respond with:
Local Diagnostics Menu
Full Duplex Communication With Selected Port.......1
Self Test Diagnostics..............................2
Loopback Data On Selected Port.....................3
Exit To System Menu................................X
Enter Request:
NOTE: The menu for Remote Diagnostics is identical to this menu
except the header will read "Remote Diagnostics Menu". When
performing remote unit diagnostics, the local Telplex will first prompt
you to enter the desired remote Telplex Unit Number followed by the
desired remote module number regardless of the diagnostic you
select. The remote module number will be "1" for a remote TX102,
TX104, TX108, or TX4. The remote module number will be 1 to 8 for
a TX28 and 1 to 16 for a TX60.
Enter the number corresponding to the desired diagnostic test. For
example, if you enter "1" (Full Duplex Communication With Selected
Port), the Telplex will respond with a prompt to enter the desired port
number. Enter the desired port number. For example, if you choose
Port 2, the Telplex will respond with:
Connected To Port 002, Type Ctrl X to exit to System Menu
NOTE: You cannot do full duplex diagnostics with a remote TX4,
TX28, or TX60 terminal port having a Serial Port Destination of Unit X,
Module 1, Port 1. If you are performing remote diagnostics on Unit X
(X = 1 to 32), Module Y (Y = 1 to 16), this menu will shown the
following:
Connected to Unit 00X, Module 00Y, Port 002
Type +++ to Return to System Menu
At this point you are in full duplex communication mode with Port 2.
Anything you type will be transmitted out Port 2 and anything received
by Port 2 will appear on your terminal screen. If performing local unit
diagnostics, type Control-X to terminate this diagnostic or +++ if
performing remote unit diagnostics. In either case, the Telplex will
return to System mode.
If you type "2" from the Local Diagnostics Menu (Self Test
Diagnostics), the Telplex will perform a self test on all local ports and
will respond with the results shown below:
Self Test Module on Local Unit
Z
passed
RAM
passed
EPROM passed
UART
passed
PORT 4 passed
PORT 3 passed
PORT 2 passed
PORT 1 passed
Once the self test has been completed, the Telplex will return to
System mode and display the System Menu. If you get a "failed"
message after any of the tests, call BayTech at 1-800-523-2702.
NOTE: The TX108 will only display that Ports 1 through 4 have
passed the self test diagnostic. The menu above will show if Port 5
through Port 8 have failed if there is a failure on any of these ports
and there is no failure on Port 1 through Port 4.
If you wish to run the loopback diagnostic, type "3" from the "Local
Diagnostics Menu" or "Remote Diagnostics Menu" (Loopback Data
On Selected Port) and the Telplex will respond with a prompt to enter
the desired port number. Type the desired port number. For
example, if you type "2" for Port 2, the Telplex will respond with:
Connected To Port 2, Type Ctrl X to exit to System Menu
NOTE: If you are performing remote diagnostics on Unit X (X = 1 to
32), Module Y (Y = 1 to 16), this menu will shown the following:
Connected to Unit 00X, Module 00Y, Port 002
Type +++ to Return to System Menu
At this point you may do loopback communication with Port 2.
Anything you type will be echoed back to your terminal screen by Port
2 and will also be sent to the device connected to Port 2. If
performing local unit diagnostics, type Control-X to terminate this
diagnostic or +++ if performing remote unit diagnostics. In either
case, the Telplex will return to System mode.
Diagnostics mode for a standard unit is accessed from the Remote
Configuration Mode menu. This menu is accessed from the Local
Mode menu (see Section 4.3.1) by tying Control-R from the active
terminal. The Telplex will respond with the Remote Configuration
Mode menu as follows

The local Telplex will return to the "Run Diagnostic" menu shown on
the previous page. If you type "2" from this menu (Full Duplex to a
select port), you may communicate with a selected port on the remote
unit with full duplex communication. The local Telplex will first prompt
you to type the desired remote unit port number (1 to 8). For example
if you type "4" for Port 4, the local Telplex will respond with:
Connected to port 4, enter ^C to quit
At this point, you are connected to Port 4 of the remote unit in full
duplex communication. Any data sent by the active terminal will be
sent to Port 4 of the remote unit and any data sent by Port 4 of the
remote unit will appear on your terminal screen. Either device may
terminate this diagnostic by typing Control-C. The local Telplex will
return to the "Run Diagnostic" menu shown on the previous page.
If you type "3" from the "Run Diagnostic menu (Loop Back
communication on a select port), you may perform loopback
communication with a selected terminal port on the remote unit. The
local Telplex will first prompt you to type the desired remote unit port
number (1 to 8). For example, if you type "4" for Port 4, the local
Telplex will respond with:
Loop Back on Port 4, enter ^C to quit
Any characters typed by the active terminal will be echoed back to the
terminal screen by Port 4 of the remote unit. Either device may
terminate this diagnostic by typing Control-C. The local Telplex will
return to the "Run Diagnostic" menu shown on the previous page. If
you type "X" from this menu, the local unit will return to the "Remote
Configuration Mode" menu shown on the previous page.
NOTE: This section does not apply to standard units.
If you type "6" (Access Local Modem) from the Telplex System Menu
(see Section 4.3.1), the Telplex will respond with the following:
COMMUNICATING WITH MODEM
Type Ctrl U to Send String 1
Type Ctrl V to Send String 2
Type Ctrl X to exit to System Menu
Here, you will be communicating in full duplex with the composite port.
Anything you type on your keyboard will be sent to the modem and
anything received by the modem will appear on your terminal screen.
Type Control-U or Control-V to send Programmable String 1 or String
2 respectively as described in Section 4.2.2.3. If you type Control-X,
the Telplex will return to the System Menu.
!
If using Modem Line Type and the power switch is turned on, the
Telplex will go through the following sequence:
1)
Perform a short self test.
2)
Send the Programmable String(s) if programmed (see
Section 4.2.2.3).
3)
Go into an idle state and either wait for a terminal to
send the Escape Code Sequence (+++) and go into
System mode/Local mode or wait for the local modem to
send a CONNECT message or a low to high transition of
DCD and go into MUX mode.
NOTE: If the Telplex enters the idle state abnormally (e.g., by the
Telplex losing power, but not the local modem) and the local modem
is still connected to the remote modem, you should enter into Access
Local Modem mode (multi-drop units) or Local mode (standard units)
and type ATO. This will cause the Telplex to return to MUX mode.
When using Direct Line Type and the power switch is turned on, the
Telplex will go through the following sequence:
1)
Perform a short self test.
2)
Go into MUX mode once the remote Telplex units
recognize each other.
The Telplex has nine LEDs and a SELECT switch on the front panel
(see Appendix B). The POWER LED indicates that power is applied
to the unit. The three MODE LEDs indicate the mode in which the
unit is currently operating. These LEDs have different meanings
depending on the type of Telplex you have. The LED description for
multi-drop units is discussed in Section 4.4.1. The LED description
for standard units is discussed in Section 4.4.2.

If a multi-drop unit is operating in Local Unit Configuration mode, the
function of the remaining LEDs is indicated by the blue TERMINAL
labels (TX, RX, RTS, CTS, DSR, DCD, and DTR). These LEDs
reflect the state of the active terminal port's EIA-232 lines. If one of
these LEDs is illuminated, this indicates that positive voltage is
detected on the respective signal.
If a multi-drop unit is not operating in Local Unit Configuration mode,
the function of the LEDs is indicated by the white COMPOSITE labels
(TX, RX, DSR, CTS, and DCD). The LEDs reflect the state of the
EIA-232 line for the composite port. If one of these LEDs is
illuminated, this indicates that positive voltage is detected on the

#
The SELECT switch on the front panel is used for multiple purposes
depending upon how Local Access and Line Type are configured. If
Local Access is disabled on all terminal ports, the SELECT switch is
used to terminate any mode of operation and go to System/Local
mode with Port 1 gaining access to System/Local mode. This is done
by pressing the SELECT switch for less than three seconds. When
using Modem Line Type, the SELECT switch is also used to initiate
the Telplex to send out String 1 to the external modem when pressed
for more than three seconds while operating in System/Local mode or
in an idle state.
The SELECT switch is also used to temporarily reset the serial
configuration and Local Access for Port 1 to factory default values
(9600 baud, 8 data bits, 1 stop bit, no parity, and Local Access
enabled) in the event you forget how the Telplex is configured. This is
done by pressing the SELECT switch and holding it down while the
unit is powering up. This procedure is referred to as fail-safe factory
default access operation. The terminal device connected to Port 1
should be configured to 9600 baud, 8 data bits, 1 stop bit, and no
parity prior to fail-safe factory default access operation.
Once the SELECT switch is released, the Telplex will send a powerup status message as discussed in Section 4.1.2.4. Send the Escape
Code Sequence to access System/Local mode. If you access Local
Unit Configuration mode, the status menus will show the values
currently stored in non-volatile memory. The status menus will not
show the temporary changes for Port 1. Cycling power on the Telplex
will cause Port 1 to revert back to the values stored in non-volatile
memory. If you happen to change the serial configuration for Port 1
after you have accessed Local Unit Configuration mode using the fail
safe method, you may save the changes permanently as described in
Section 5.3.
Data flow control between the composite ports of remote Telplex units
is accomplished via internal protocol that is transparent to each
terminal port. However, either Telplex will respond to the hardware
flow control lines of an external modem connected to the composite
port. Each terminal port has a 256 character receive buffer and a
7.5K transmit buffer.
Data flow control for the terminal ports is accomplished by hardware
handshaking (CTS output and DTR input) or XON/XOFF
handshaking. The desired flow control can be enabled on individual
terminal ports in both the transmit data (TX) and receive data (RX)
directions. You may also program individual terminal ports to pass
the status of its RTS input handshake line through to the DSR output
handshake line of the designated remote terminal port.
###
When information is received by a Telplex terminal port, the data is
stored in a receive buffer and is subsequently transmitted to the
remote unit through the composite port. If the receive buffer fills, the
local Telplex will make the terminal port's CTS line false (negative
voltage), signaling that it cannot receive more data. When the buffer
empties to the point where the port can accept more data, the local
Telplex will make the terminal port's CTS line true (positive voltage),
signaling that it can accept more data.
The local Telplex will also make the CTS line false for a terminal port
if the transmit buffer of the designated remote terminal port fills.
When the Telplex transmits data out of a terminal port, the unit will
expect to see a false (negative voltage) on the DTR line if the terminal
device is unable to accept data. When the terminal device is ready to
accept data, the Telplex will expect to see a true (positive voltage) on
the DTR line.
If the DTR line is false on a local terminal port, the transmit buffer for
that port will begin to fill. If the transmit buffer fills, the local unit will
signal the remote unit to make the CTS line false on the designated
remote terminal port.
If XON/XOFF handshaking is enabled in the transmit data direction,
the Telplex will still check the state of the DTR line when transmitting
data out of a particular terminal port. By leaving the DTR line
disconnected, the DTR line is always enabled.
##
If RTS/DSR pass through is enabled for a local terminal port on the
Telplex, the state of the RTS input line for this port will be reflected on
the DSR output line of the designated remote terminal port.
As an example, refer to Figure 1 on page 2. Suppose RTS/DSR pass
through for terminal Port 1 on both units is enabled. If Port 1 of Unit 1
receives a false condition (negative voltage) on the RTS line, Unit 1
will signal Unit 2 to make the DSR line of Port 1 false.
If RTS/DSR pass through is disabled for a Telplex terminal port, the
DSR line for that port will remain a constant +12 VDC while power is
applied and the RTS input line will be ignored.
The factory default RTS/DSR pass through setting is disabled for
all terminal ports.
The Telplex permits XON/XOFF to be enabled or disabled by port
independently, in the receive data (RX) and transmit data (TX)
directions. The description of handshaking assumes XON/XOFF to
be enabled in both directions. If XON/XOFF is disabled in one
direction, that direction will support hardware handshaking.
$%$&
When information is received by a Telplex terminal port, the data is
stored in a receive buffer and subsequently transmitted to the remote
unit through a composite port. If the receive buffer fills, the Telplex
will send an XOFF character signaling the terminal device that it
cannot accept more data. When the buffer empties to where it can
accept more characters, the Telplex will send an XON character.
The Telplex will also send an XOFF character out of a local terminal
port if the transmit buffer of the designated remote terminal port fills.
%&
When the Telplex transmits data to a terminal device and the terminal
device cannot receive any more data, the unit will expect to receive an
XOFF character. When the terminal device can receive more data,
the Telplex will expect to receive an XON character.
If a terminal port on the local unit receives an XOFF character, the
transmit buffer for that port will begin to fill. If the transmit buffer fills,
the local unit will signal the remote Telplex to handshake the
designated remote terminal port.
The programmable features of the Telplex may be accessed from any
terminal port which has Local Access enabled (see Section 4.1.2.3).
From the factory, Port 1 is the only terminal port that has Local
Access enabled. You may also program the terminal port features for
a remote Telplex by accessing Remote Unit Configuration mode.
User-programmable features for the terminal ports include serial port
configuration (i.e., baud rate, word size, etc.), Block Size, and Status
Messages. Serial Port Destination and Unit Number are
programmable for multi-drop units only. User-programmable features
for the composite port includes baud rate, Line Type, Clock Type, and
Programmable Strings.
The procedure for configuring multi-drop units and standard units is
basically the same. However, the resulting configuration menus are
different in appearance. These differences will be specified in the
following sections. The menus shown will be for the TX104 which are
similar for the TX102 and TX108.
To access Local or Remote Unit Configuration mode for either type of
Telplex, use the following procedure:
1.
Connect a dumb terminal or a computer emulating a dumb
terminal to the desired terminal port (factory default is Port 1).
Make sure your terminal device is configured to operate at the
same serial parameters as the terminal port on the Telplex.
Factory default is 9600 baud rate, 8 bit word size, 1 stop bit, no
parity, and XON/XOFF handshaking disabled.
2.
Send the Escape Code Sequence (one second delay followed
by +++ and another one second delay). If you are
programming a multi-drop unit, you will receive the System
Menu similar to the following for the TX104:
TELPLEX TX104 SYSTEM MENU
Local Unit Configuration......1
Remote Unit Configuration.....2
Mux Mode......................3
Local Diagnostics.............4
Remote Diagnostics............5
Access Local Modem............6
Enter Request:
If you are programming a standard unit, you will receive the
Local Mode menu similar to the following for the TX104:
3.
If you are programming a multi-drop unit, Type "1" for Local
Unit Configuration or "2" for Remote Unit Configuration in
response to the prompt. If you are programming a standard
unit, type Control-T for Local Unit Configuration or Control-R for
Remote Unit Configuration. From this point on, configuration of
the Telplex is accomplished by following the menus that prompt
you.
NOTE: If you choose Remote Unit Configuration for a multidrop unit, the local Telplex will first prompt you to enter the
desired unit number and module number of the remote Telplex.
The module number will be "1" for a remote TX102, TX104,
TX108, or TX4. The module number will be 1 to 8 for a remote
TX28 or 1 to 16 for a remote TX60.
Section 5.1.1 shows the main configuration menu for multi-drop units.
Section 5.1.2 shows the main configuration menu for standard units.

Enter request or X to Exit:
Enter the number corresponding your desired choice. For example, if
you enter "1" (String 1), the Telplex will respond with:
Enter ASCII string 42 characters max.
Use Prefix ^ for Ctrl-Characters
Enter the desired string (up to 42 characters). If String 1 must include
control characters, use the prefix ^ (5E hex or ASCII 94) to represent
the Control key. For example, if you want the string to include
Control-T, you would enter ^T in response to the prompt along with
the rest of the desired string. The entry must be followed by the
<ENTER> key.
NOTE: All AT commands require a Carriage Return at the end of the
command(s) before the modem will execute the command(s).
Therefore, ^M (Control-M or Carriage Return) should be the last
character entered in either programmable string.
For example, if you want the local unit to send String 1 to instruct the
external modem to tone dial the remote unit's external modem at
number 1-555-123-4567 upon power-up or loss of DCD, you would
first enter the following string:
Enter Up to 42 Characters to be Sent for String:ATDT15551234567^M

Enter Request or X to Exit :
Enter the number corresponding to the desired Line Type.
IMPORTANT: If you intend to connect an external modem to the
composite port, you must choose Modem Line Type. If you choose
Modem Line Type, keep in mind this does not configure the external
modem to communicate with a dial or leased line. If you intend to
connect the Telplex via cable, you must choose Direct Line Type.
If the baud rate and/or Line Type is acceptable, type "X" (Exit/Save)
and the Telplex will respond with:
Save Baud Rate Changes Permanently ? (Y/N):
If you enter "Y", the new baud rate for the composite port will be
stored permanently in non-volatile memory and the Telplex will
subsequently power up at that configuration. If you enter "N", the new
baud rate will be stored in RAM and on the next power-up, the Telplex
will revert to the previous configuration.
IMPORTANT: When using Direct Line Type and you change the
baud rate of the local unit's composite port, the remote unit's
composite port baud rate must then be changed in order to reestablish MUX mode with the local unit.
The Telplex will now return to the main configuration menu (see
Section 5.1).
)
By responding to the Enter Request: message at the end of the main
configuration menu with "X" (Exit), the Telplex will return to System
mode.
NOTE: This section does not apply to standard units.
This section is intended to provide the necessary configuration
requirements for various multi-drop applications. We will give specific
instructions on how to configure each unit. We assume that all
terminal devices and modems communicate at the factory default
serial parameters. The configuration parameters we will consider in
this section are the Serial Port Destination and Unit Number.
*!!*
The first example application we will consider is a "point-to-point"
application. Figure 9 below shows two TX104s. This application links
mainframe ports at one site to terminals at another site. The TX104
with the main frame ports connected to it will be Unit 1 and the TX104
with the terminals connected to it will be Unit 2.
Figure 9
In this application, ports on Unit 1 will communicate with respective
ports on Unit 2. Use the following guidelines to configure each unit for
this application:
1.
Connect a terminal to Port 1 of the TX104 that will be located
at the site with the terminals (Unit 2). Access System mode by
typing +++. Access Local Unit Configuration mode and change
the Unit Number from "1" to "2" (see Section 5.7). If using
modems to connect to Unit 1, change the Line Type to
"Modem" (see Section 5.8) and configure the Programmable
Strings if desired (see Section 5.5 and Section 4.2.2.3.).
2.
Connect a terminal to Port 1 of the TX104 that will be located
at the main frame site (Unit 1). Access Local Unit
Configuration mode and change the Destination Unit for each
port to "2" (see Section 5.6). If using modems to connect to
Unit 2, change the Line Type to "Modem" and configure the
Programmable Strings if desired.
3.
Connect the composite ports of each TX104 together via
modem or cable (see Section 3.5.).
**
For the "star" application, we will consider a local TX60 that has four
terminal port modules (installed as Module 1 through Module 4) and
four composite modules to communicate with four remote TX104s as
shown in Figure 10 below. The TX60 Composite modules are labeled
as Composite 1 through Composite 4 and will installed as Module 5
through Module 8 respectively.
Figure 10
Here the ports on Module 1 will communicate with TX104-1 (Unit 1)
through Composite 1, the ports on Module 2 will communicate with
TX104-2 (Unit 2) through Composite 2, ports on Module 3 will
communicate with TX104-3 (Unit 3) through Composite 3 and the
ports on Module 4 will communicate with TX104-4 (Unit 4) through
Composite 4. The main frame ports will be connected to the local
TX60 (Unit 5) and terminals connected to the TX104s. Use the
following guidelines to configure each unit for this application:
1.
Access Local Unit Configuration mode for the individual
TX104s and configure each to have the appropriate Unit
Number. If using modems for connection to the remote TX60,
change the line type to "Modem" and configure the
Programmable Strings if desired.
The Serial Port Destination for the terminal ports on each
TX104 should be configured as follows:
TX104 SERIAL PORT DESTINATIONS FOR
EXAMPLE "STAR" APPLICATION
TX104-X
Unit X
(Ports 1-4)
Serial Port Destination
Unit
Modul
e

1
1-4
2
5
2
1-4
3
5

1-4
The Serial Port Destination for each TX104 may be configured
locally from each unit or remotely from the TX60 once the TX60
has been configured and the composite modules have been
connected to the respective TX104 composite ports (see Step
5).
2.
Refer to the documentation for the TX60. Access Local Unit
Configuration mode for Module 1 and change the Unit Number
from "1" to "5". Exit to the System Menu.
3.
Access Local Unit Configuration for Module 5 (Composite 1)
and add Unit 1 to the Multiple Unit Configuration. Likewise,
add Unit 2 to the Multiple Unit Configuration for Module 6
(Composite 2), Unit 3 for Module 7 (Composite 3), and Unit 4
for Module 8 (Composite 4). If using modems for connection to
the remote TX60, change the line type to "Modem" and
configure the Programmable Strings if desired.
4.
Access Local Unit Configuration mode for Module 1 through
Module 4 and change the Serial Port Unit Destination number
for each individual port to Unit 1 for ports on Module 1, Unit 2
for ports on Module 2, Unit 3 for ports on Module 3 and Unit 4
for ports on Module 4.
5.
(
Connect the composite ports of each TX104 to the respective
composite port on the TX60 via modem or cable (see Section
3.5). Once the units recognize one another, you may configure
the required Serial Port Destinations for each TX104 (as shown
in the table on the previous page) remotely from the TX60.
Since there are no adjustments and no moving parts in a Telplex,
preventative maintenance is unnecessary.
(
#

Print Master 700 Series printer controllers are made in several
different configurations satisfying various interface requirements.
Each unit allows computers to share, select and/or contend for
printers easily and economically, without switching cables. The
internal buffering system allows simultaneous, high-speed input from
all connected computers and output to all printers. Models come in
six, eight, and ten port sizes. All have a 1 MB, dynamically allocated
buffer that may be expanded to 2 MB. The 706A and 708A all parallel
port models feature super fast throughput (up to 60,000 characters
per second) and an expandable buffer size up to 4 MB.
Print Master II 800 Series peripheral sharing devices connect
between your computers, printers, plotters, modems and other
peripherals. These models allow any of your computers to access
any of your peripherals -- and talk to other computers so files can be
transferred and data shared. Plus, a built-in buffer spools output data
until your peripherals can receive it, freeing your computers to go on
to other tasks. Models come in four, eight, and ten ports. Four port
models have a 1 MB standard buffer which is expandable to 2 MB.
Eight and ten port models have a 256 KB buffer which may be
increased to 1.2 MB.
Model 24SII DES Data Exchange System is the fastest peripheral
sharing solution available with throughput speeds up to 60,000
characters per second. The total number of ports may be expanded
from 4 to 24 ports using 4-port I/O modules. Any port can be
configured as an input or output port. The standard 1.0 MB buffer can
be increased to 16 MB by user installed memory packages. Plus,
using popular communications software, this unit allows for computer
to computer high speed data transfer as well as modem sharing.
LaserShare is an intelligent printer controller that allows up to four or
eight computers to send data to a single HP LaserJet laser printer.

You may use an Ethernet 10BASE2 (thin coax) or 10BASE-T (twisted
pair) network interface. The BayTech print server services up to 32
print queues distributed on as many as 32 file servers.
TRAN-X high speed parallel/serial converter products allow you to
extend parallel cables to 1000+ feet and allow your network server,
graphics workstation, or PC to send/receive data at speeds up to
46,000 characters per second. You can use the Tran-x Series with
BayTech Model 24SII, LaserShare, or network print servers for the
fastest long distance peripheral sharing solution available anywhere.
Modular cabling provides simplicity in connections between remote
devices. Tran-x LPT-460 card plugs directly into your PC expansion
slot. Tran-x PS-02 connects to your PC's parallel port. Tran-x SP-01
connects to the Centronics connector of a parallel printer. Tran-x SP02 connects to the DB-25 parallel port of the BayTech 700 Series
Print Master, 800 Series Print Master II, or Model 24/24SII DES
peripheral sharing units.
"500H" Series and Model 24SII DAC Data Acquisition and Control
units connect between one host computer and multiple peripheral
devices. These models are often used in industrial process-control
environments (e.g., for allowing control of multiple numerical or
assembly-line machines), in exchanging data between point-of-sale
devices, or for operating a number of laboratory instruments or
business machines from a central computer. They are especially
effective in adapting small low-cost personal computers to these
applications. Each unit features six modes of operation which may be
easily configured to your application. The 500H series models are
available with either 5 or 9 ports. The Model 24SII DAC unit is
expandable from 4 to 24 ports in 4-port modular increments.
Model M16 DAC and Model M8 DAC Data Acquisition and Control
units are multifunction, user-configurable systems capable of
providing a wide range of data collection, communications, and device
control. Possible applications include security alarm monitoring
process control, medical data systems control, manufacturing and
