The BayTech Model 24SII Data Exchange System (DES) is a high performance peripheral sharing solution offering versatile and flexible connectivity between computers and various peripheral devices. Computers may share plotters, modems, and laser printers, as well as access other computers to share data bases and transfer files. Cost effectiveness is thus achieved through resource sharing among multiple users. Figure 1 below shows a Model 24SII DES with twenty-four ports installed.
Each port offers high speed data communication with unidirectional serial throughput up to 460k bits per second (bps) and parallel speeds exceeding 60k characters per second (cps). The Model 24SII controller board is used primarily as a data communications bus with throughput capability up to 5.5M bps. The controller board allows direct communication with the connected modules or routes data to the memory module for print spooling. The dynamically allocated buffer is available from 1MB up to 16MB.
The Model 24SII's generous built-in buffer also saves valuable computer time by spooling data until the printer or plotter can receive it, keeping your users and computers working full time instead of waiting. The spooling buffer on the Model 24SII DES can range from 0 MB to 16MB in 1MB or 4MB increments. The buffer is field upgradable. For printer and plotter sharing applications, you must have a minimum of 1MB installed on the initial purchase.
BayTech sells a high speed serial module for the Model 24SII DES which supports EIA-422 protocol (M24SII-V07). This allows for long cable distances using RJ-11 (4-wire) or RJ-45 (8-wire) modular cabling. Use of the BayTech Tran-x LPT-460 or PS-02 high speed parallel/serial converter products will allow your PC to transmit data at 460k bps using cable lengths up to 1000 feet. The same set up will allow your cable distance to be up to 4000 feet if your Tran-x card is configured to transmit data at 115k bps.

This section provides basic installation instructions for persons knowledgeable in the area of computer equipment installation. In this section, we assume that the Model 24SII DES has never been configured (i.e., all settings are factory default values). We will refer to specific sections in this manual for more in-depth instructions on installation, operation, and configuration.
Step Instructions/Application Questions Action/Special Instructions printer or plotter, you must reconfigure the Port Designation of a parallel port on the Model 24SII DES to be a printer port. Additionally you must reconfigure the Port Designation for Port 2 of Module 1 to a computer port. Will you be connecting any serial devices that will communicate with serial parameters different than 9600 baud, 8 data bits, 1 stop bit, no parity, and XON/XOFF handshaking disabled (e.g.
The information contained in this section is provided as an overview and guide to configuration and set-up of the Model 24SII DES. The appropriate sections of the manual should be referred to for more indepth information pertaining to a specific function or for alternative methods. After opening the box, check the packing list that comes with the Model 24SII DES to ensure that you have received all components.
To run INSTALL, use the following procedure: 1. Insert the software utility diskette into drive A (or drive B) and from the prompt type INSTALL followed by ENTER. 2. A menu titled "Drive & Directory Definitions" will appear on your screen. This menu will display the Source Drive, Destination Drive, and Destination Directory. The Source Drive is the floppy drive where the diskette is inserted (default is drive A).
The standard Model 24SII DES requires 115 VAC, 50/60 Hz. power and comes with a three-prong power cord. Do not attempt to operate the unit with a two-prong socket or adaptor. 230 VAC, 50/60 Hz. is optional. The Model 24SII DES powers-up when you press the power switch, located on the front of the unit, to "ON". A green LED on the front panel will illuminate when power is applied. CAUTION: Power should be turned off anytime cables are to be installed or removed.
Connect the proper serial cable between COMx (where x = 1, 2, 3, or 4) of a PC, or dumb terminal, to Port 1 of Module 1 (the master configuration port). All other cables can be connected after the system is configured (see Section 8). From the factory, the Model 24SII Data Exchange System is set up with Port 1 of Module 1 (serial) designated as a computer port. Port 1 of Module 1 is the master configuration port and must always be a serial port.
Serial ports power-up from the factory at: 9600 baud rate 8 bit word size 1 stop bit no parity XON/XOFF disabled Printer sharing mode: Bidirectional. 4-Wire/8-Wire Operation (M24SII-V07 high speed serial module only): 8-wire. If your application does not match the factory setup of the Model 24SII DES, you must first reconfigure the Model 24SII DES by entering the configuration mode (see Section 8).
If using an IBM PC or compatible to configure the Model 24SII DES, first make a copy of the BayTech supplied support software disk and store the original in a safe place. (Refer to your DOS manual for copy instructions). You will be using the TERM program created by running the INSTALL program (see Section 4.2) to change the default configuration of the Model 24SII DES. Any terminal emulation program supplied by another manufacturer may also be used.
3. Refer to the upper right hand corner of the screen for Handshaking line status. RTS, CTS, DSR, and DTR should all be HIGH. The DCD line is not looked at by the terminal emulation program therefore its status can be ignored. If these signals are not high at this point, check to ensure the correct cable is connected. 4. Ensure that all red LEDs on the front of the Model 24SII DES are off (all ports off-line), and that the green 'power on' LED is illuminated.

This section is intended to provide instructions on how to set up your PC to work with the Model 24SII DES with respect to the BayTech software (if you intend to use it) and special considerations to keep in mind when connecting your PC to the Model 24SII DES in parallel or in serial.
You will also need to change the serial port configuration of your PC COM port to match that of the Model 24SII's Serial Port Configuration. If you will be using the Model 24SII's factory default Serial Port Configuration (9600 baud, 8 data bits, 1 stop bit, and no parity), this is accomplished via the following DOS command: Mode COMx: 9600,n,8,1,P where x is the number of the appropriate com port. This command should be part of your AUTOEXEC.BAT program.
If you are connecting your PC to the Model 24SII DES in serial and are not going to use the BayTech software, you would not need to modify your PATH command or include the RAMEXEC command in the AUTOEXEC.BAT file. If you are connecting your PC in parallel and intend to use the BayTech software, you would not include either MODE command in the AUTOEXEC.BAT file (unless you are using your com port for another application outside the Model 24SII DES).
The pin assignment for the DB-25 connector is similar to the IBM PC parallel connector and uses the following signals for communication: DB-25 STANDARD CENTRONICS TTL LEVELS BayTech Cable part # MC25S010 PIN # SIGNAL 1 - Strobe 2 +Data Bit 0 3 + Data Bit 1 4 + Data Bit 2 5 + Data Bit 3 6 + Data Bit 4 7 + Data Bit 5 8 + Data Bit 6 9 + Data Bit 7 10 - Acknowledge 11 + Busy 12 + P.

The following devices are generally DTE: terminals, printers, computers like the IBM PC. The following devices are DCE: modems and some computers. If your device transmits data on Pin 2 or receives data on Pin 3, it is DTE.
If you are interfacing a DCE device to the Model 24SII DES (DTE), you must use a one-to-one or straight cable as shown in Figure 3 on the following page. If you are interfacing a DTE device to the Model 24SII DES (DTE), you must use a crossed cable as shown in Figure 4 on the following page.

The M24SII-V05 and M24SII-V06A I/O modules have RJ-45 modular connectors.
NOTE: Please confirm that you have the M24SII-V06A module. Check the top of the module for the part number. If you have an M24SII-V06 module (i.e., no A suffix), please call a BayTech Applications Engineer for the correct pin/signal definition and the correct adapter information. Figure 7 and Figure 8 are drawings of a RJ-45 receptacle and plug. The pin number assignments are given.
! "# $ ! % ! % NOTE: Ports on the M24SII-V07 module may be individually configured to communicate with either EIA-232 or EIA-422 (default) protocol via jumper setting. In addition, you may program individual ports to use either 8-wire (RJ-45 - default) or 4-wire (RJ-11) cabling.
If you will be using 4-wire Operation, please use the reference chart below to determine the applicable sections based on your application. 4-WIRE OPERATION OPTIONS Printer Sharing Mode Protocol Application See Section: Bidirectional 1 X 2 X Unidirectional EIA-422 X 5.5.2.1 X 3 X 4 X EIA-232 & X 5.5.2.2 5.5.2.3 X 5.5.2.4 NOTE: This configuration will support hardware or XON/XOFF handshaking and bidirectional Printer Sharing Mode.
If you are connecting an EIA-232 device to the M24SII-V07 module using 8-wire Operation, please see Appendix A.5 for device adapter pinouts and recommended cabling. When connecting an EIA-422 device to the M24SII-V07 module using 8-wire Operation, the cable required to connect the two devices must have TX+ wired to RX+ (and vice versa), TX- wired to RX- (and vice versa), HSO wired to HSI (and vice versa), and have the signal grounds connected. Please Figure 9.
NOTE: Ports using this configuration will support XON/XOFF handshaking only. You must enable XON/XOFF handshaking in configuration mode for these ports (see Section 8.8.1) and on the equipment that will connect to these ports.
COMPUTER PORTS NOTE: Computer ports using this configuration will support hardware handshaking only. You must ensure hardware handshaking is supported by the equipment that will connect to these ports.
PRINTER PORTS NOTE: Printer ports using this configuration will support hardware handshaking only. You must ensure hardware handshaking is supported by the equipment that will connect to these ports.
NOTE: Ports using this configuration will support XON/XOFF handshaking only. You must enable XON/XOFF handshaking in configuration mode for these ports (see Section 8.8.1) and on the equipment that will connect to these ports.
If you are connecting a device other than another BayTech product, you must refer to the operator's manual for your equipment to determine which pins are defined as TX+, TX-, RX+, and RX-. If you are using 4-wire Operation and bidirectional Printer Sharing Mode and connecting to another BayTech product (such as Tran-x), please refer to Appendix A.7.4 for the recommended cable pinout.
When connecting an EIA-422 device to a computer port on the M24SII-V07 I/O module using 4-wire Operation and unidirectional Printer Sharing Mode, the cable required to connect the two devices must have RX+ wired to TX+, and RX- wired to TX-, HSO+ wired to HSI+, and HSO- wired to HSI-. Please see Figure 11 below.
PRINTER PORTS NOTE: Printer ports using this configuration will support hardware handshaking only. You must ensure hardware handshaking is supported by the equipment that will connect to these ports.
NOTE: If your EIA-422 device has only one output hardware handshake line (i.e., no HSO+ and HSO-), connect this single handshake line to HSI- on the M24SII-V07 module (Pin 5). If you are connecting a printer port on the M24SII-V07 module to another BayTech product (such as the Tran-x SP-01 or SP-02) using 4-wire Operation and unidirectional Printer Sharing Mode, please refer to Appendix A.7.4 for the recommended cable pinout.
The Port Logical Name is simply an aid to identifying which device is connected to which port. It is used in the configuration menus and the I.D. Page Message. It has no function other than identification. Factory default is Device A for Port 1, Device B for Port2..... Device X for Port 24. The Model 24SII DES may have a total number of ports ranging from 4 to 24, in multiples of 4.
' "# ( You may configure the number of printer ports on the M24SII-V02 parallel module to be 0 to 4. If you will be connecting any printers to this module, the printers would physically connect to the higher numbered ports. For example, if you will be connecting 2 parallel printers to a M24SII-V02 high speed parallel module, you would attach the printers to Port 3 and Port 4 of that module. Factory default configuration for Number of Printers is 0.
If the computer is communicating with 7 bit word size with parity enabled, the 8th or parity bit is masked from the Port Select Code before it is examined, allowing you to send the Port Select Code with odd or even parity. Factory default is $SELECT. In multiple printer applications, you may select printer ports either anytime while printing or before the print job only.
The Model 24SII DES will translate for serial devices using different configurations. This allows you to mix-and-match devices having different configurations. You may set the baud rate, word size, stop bits, parity and XON/XOFF (transmit and receive) for each individual serial port. For high speed serial modules, you may also program the printer sharing mode to either bidirectional or unidirectional.
& The Model 24SII DES has four Form Feed Modes allowing you to determine when form feed occurs at the printers you are selecting: at the beginning of printing, at the end of printing, or both. This feature is useful when sending DOS files to a laser printer. Factory default is no form feed. ) You can print a programmable message and the Logical Name of the source computer on a separate sheet of paper before or after printing any other data. You can enable or disable the I.
The Model 24SII Data Exchange System allows peripheral (printer, plotter) sharing, specific peripheral selection or peripheral contention, and buffering of print data. The Model 24SII DES will let several users automatically share one printer. In multiple printer applications, it will let users contend for the next available printer on a first-come-first-served basis or select a specific printer.
In multiple printer applications, the Model 24SII DES gives you the capability of sending print jobs to the first available printer (contention mode). You may put the Model 24SII DES into contention mode by changing the Default Printer Assignment to 0-0 for the individual computer port(s) while in configuration mode (see Sections 6.10 and 8.14). The data is sent to the Model 24SII's buffer and passed to the next available printer on a first-come-first-serve basis.
The Model 24SII DES powers-up from the factory in contention mode. To select a specific peripheral in multiple printer/plotter applications, the computer sends a port select sequence which consists of the user-defined Port Select Code (factory default is: $SELECT), the module number the printer is connected to (1 to 6), followed by the desired printer port number on that module (1 to 4) and a terminating character: 0D Hex (Enter/Return) or 0A Hex (Line Feed).
The port select sequence may be sent as a separate ASCII file preceding the print job, via DOS batch files, as part of a printer initialization string, or by using the utility software. % A print job starts when the Model 24SII DES receives 3 or more characters from a computer.
In Port Select Mode B (printer selection at beginning of printing), a print job is ended only when no characters are received by the Model 24SII DES from the computer for the specified Input Inactivity Timeout period only. CAUTION: The Input Inactivity Timeout should not be set to 0 (zero) seconds (disabled) in Port Select Mode B. Mode B operation cannot recognize a manual disconnect or clear buffer command until the current print job is ended via the inactivity timeout period.
If a computer wishes to clear the buffer, the computer sends the Port Select Code followed by CLR and a terminating character (Enter/Return or Line Feed) to the Model 24SII DES. This command will only affect print jobs originated by that particular computer. Print jobs in the buffer from other computers are not affected. The clear buffer command will clear print jobs currently queued in the buffer and also a print job in process, if one is printing.
The Model 24SII Data Exchange System allows pairs of computers (or computers and other devices such as modems, scales, data collection equipment, etc.) to communicate while other computers are sending data to the print buffer and the Model 24SII DES is sending data to printers. Full duplex communication allows file transfer with many popular communications software packages. NOTE: Computer-to-computer communication can occur only if both ports communicating are serial.
Do not send both Enter/Return and Line Feed as the terminating character. The Model 24SII DES looks for either Enter/Return or Line Feed as the terminating character, but not both. If you send both Enter/Return and Line Feed as part of the disconnect sequence, the Model 24SII DES will not recognize the disconnect sequence unless there is a two second delay between Enter/Return and Line Feed.
NOTE: Using RAMEXEC to select another computer port is not suggested. This is because RAMEXEC does not provide full duplex communication so you cannot see the On Line or Busy message if you attempt to use RAMEXEC to determine whether or not you got connection to the other computer port. Modem sharing can be achieved with a computer-to-computer connection through the Model 24SII DES.
For example, suppose you want to communicate with a 2400 baud modem connected to Port 2 of Module 2 and your PC is connected to a computer port set at the Model 24SII's factory default serial configuration (9600 baud, 8 data bit, 1 stop bit, no parity, and XON/XOFF disabled). Port 2 of module 2 would need to be configured to communicate at 2400 baud to match the baud rate of the modem.
BETWEEN COMPUTER AND PERIPHERAL THROUGH MODEL 24SII When a computer transmits data to a peripheral device through a computer port on the Model 24SII DES, the data is received and stored in the spooling buffer (standard 1MB; optional up to 16MB) which in turn retransmits it to a peripheral device through a printer port.
BETWEEN COMPUTER AND COMPUTER THROUGH MODEL 24SII When Computer A transmits data to Computer B through the Model 24SII DES, the data is received from Computer A and stored in a 512-character buffer which in turn retransmits it to Computer B. When the buffer fills, the Model 24SII DES will make the DTR line low to Computer A, signaling Computer A that it cannot accept more data. When the Model 24SII DES retransmits the data to Computer B, the Model 24SII DES will expect to see a high on the CTS line.
BETWEEN COMPUTER AND PERIPHERAL THROUGH MODEL 24SII When a computer transmits data to a peripheral device through a computer port on the Model 24SII DES, the data is received and stored in the spooling buffer (standard 1MB; optional up to 16MB) which in turn retransmits it to a peripheral device through a printer port. During transmission, when the buffer fills, the Model 24SII DES will send an XOFF, signaling the transmitting computer that it cannot accept more data.
When the buffer of the Model 24SII DES can receive more data, the Model 24SII DES will send an XON to Computer A. NOTE: For computers sending binary data and using XON/XOFF handshaking, the input flow control (Recv) should be enabled and the output flow control (Xmit) should be disabled. This will allow any XON or XOFF character sent in the binary string to be passed through the Model 24SII DES to the receiving device.
This command should be entered in all capitals with only one space between ECHO and the $. Please refer to you DOS manual for instructions on creating DOS batch files. Programs such as Word Perfect and WordStar typically send a printer initialization string before any data. The port select sequence may also be embedded in this string to select a printer. For example, Word Perfect allows you to edit the printer definition file for a specific printer by using the PTR command.
& Configuration changes for the entire Model 24SII DES are made through the master configuration port which is Port 1 of Module 1. Port 1 of Module 1 must always be a serial port to allow configuration to occur. The master configuration port has access to the configuration of all ports on the Model 24SII DES and can program all options of the configuration mode one module at a time.
To access the configuration mode of the Model 24SII DES, use the following procedure: 1. Connect a dumb terminal (or a PC running a terminal emulation program) to the master configuration port (Port 1 of Module 1) or to any serial computer port. Configure your terminal's serial parameters to match those of the Model 24SII DES. From the factory, all serial ports on the Model 24SII DES are factory set at 9600 baud rate, 8 word size, 1 stop bit, no parity, and XON/XOFF disabled.
NOTE: A serial computer connected to a port other than Port 1 of Module 1 cannot access configuration mode for its module while the master configuration port is configuring a module.

OTHER BAYTECH PRODUCTS 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.
LaserShare is an intelligent printer controller that allows up to four or eight computers to send data to a single HP LaserJet Series II, IID, III, IIID, Brother HL8e* and HL8v*, or Wang LDP8 laser printer. LaserShare connects directly into the optional I/O slot of the laser printer. Power is taken directly from the laser printer so there is no need for a power cord. LaserShare can accept data from all ports simultaneous and is printed on a first-in first-out basis.
"500H" Series and the 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.
Telplex Model TX108M is an asynchronous statistical multiplexer with built-in modem. Eight individual communications channels are multiplexed into a single dial-up or leased telephone line, cutting phone line costs to a minimum. The TX108M features a V.32 internal modem with MNP Class-4, which provides reliable communication at speeds up to 9600 bps. Telplex Model BX9600 is an external asynchronous 9600 bps modem. The BX9600 features V.
Networking (F-Series): Networks either 5 or 9 ports together, i.e., allows any port to connect to any other port on the multiport controller. These also have host port control which allows a host computer system to make and/or break any connection between two ports on the multiport controller.
