This section provides basic set up instructions for those knowledgeable in computer equipment installation. We will refer to specific sections in this manual for more in-depth instructions on installation operation, and configuration. Please review the following procedure: Step Instructions 1 Determine what model Print Master you are installing. The model number is written on the front panel as shown below for the model 708A.
Step Instructions connect to ports assigned as printer. All ports are flexible except as noted below (i.e., ports may be configured as computer or printer).
Step Instructions A. Serial Ports Serial ports on Print Master are DCE. Therefore, straight cabling is required between the computer's serial port and Print Master's serial port. A straight cable is also required between Print Master's serial port and the serial port of a printer or plotter. B. Parallel Ports A straight through 25 pin parallel DB-25 male to DB-25 male cable is required to connect the parallel port of a computer to a parallel port of Print Master.
Step Instructions To print from a serial port of your PC, you must first redirect the parallel output to the serial port via the DOS command C:>MODE LPTx:=COMy:, where x and y are the port designation (e.g., LPT1:=COM1:). You must also configure your PC's serial port to communicate at parameters that match Print Master. This is done via the DOS command C:>MODE COMy: 9600,n,8,1,p, where y is the com port number of your PC. This MODE command assumes you are using factory default values.
After opening the box, check the packing list that comes with Print Master to ensure that you have received all components. Also check the unit to make certain that it did not receive damage during shipping. BayTech provides utility software to assist you in configuring the Print Master. There are three peripheral selection programs included to provide easy device selection from text mode, graphics mode, or Windows.
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 . 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. The Destination Drive is the drive where the expanded files will be copied to (default is drive C).
The Print Master 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 adapter. 230 VAC, 50/60 Hz. is optional. The Print Master powers-up when you press the power switch on the back of the unit to "ON" or "1". Power-on is indicated on the front panel by the illuminating of a green LED. CAUTION: Do not attempt to make any internal changes.
This section provides instructions on how to set up your PC to work with Print Master with respect to the BayTech software (if you intend to use it) and special considerations when connecting your PC in serial. If you intend to use the RAMEXEC or RAMTSR hot key programs to select between multiple peripherals, you would typically add the command C:>RAMEXEC or C:>RAMTSR to your PC's AUTOEXEC.BAT file.
You will also need to change the serial port configuration of your PC's com port to match that of the Print Master. If using the Print Master's factory default serial configuration, this is accomplished via the DOS command C:>MODE COMy: 9600, N, 8,1,P where y is the number of the appropriate com port. This command should be part of your AUTOEXEC.BAT file. Alternatively, you may use the SMODE.EXE utility to operate at speeds greater than 9600 bps.
Please see Section 5.1 for parallel port cabling information, Section 5.2 for DB-25 serial port cabling information, or Section 5.3 for RJ-45 cabling. Appendix A provides recommended cabling pinouts. Parallel ports on Print Master have DB-25 female connectors. A straight, DB-25 male-to-male cable is required between each IBM PC computer (or compatible) and a parallel port on Print Master.
IMPORTANT: Before you proceed with cabling, you must know whether the devices that you will connect to Print Master 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. If your device transmits data on Pin 2 and receives data on Pin 3, it is DTE.
DTE ports use the following signals for communication: DTE PORT PIN/SIGNAL DEFINITION Pin Signal (EIA-232) Direction Description 1 PGND --- 2 Tx Output 3 Rx Input 4 RTS Output 5 CTS Input Clear To Send: Input handshake line. Must be positive voltage before DTE device will transmit data. 6 DSR Input Data Set Ready: Input handshake line. Must be positive voltage before DTE device will transmit data.

! " # $ The EIA-232 serial ports of the Print Master Models 706C, 708C, or 710C may have RJ-45 modular connectors. This section will address the cabling and modular adapter information required for 700C models with RJ-45 modular connectors. BayTech has a complete line of RJ-45 adapters and cables that will make your installation quick and trouble free. Call your dealer or BayTech for order information.
Figure 4: RJ-45 Receptacle Figure 5: RJ-45 Plug Please see Appendix A.5 for modular adapter pinout and cabling information. This section discusses the various user-programmable configurations (Section 6.1), printer sharing operation (Section 6.2), the LED indicators (Section 6.3), and data flow control (Section 6.4).
# % # Individual ports on Print Master may be configured as computer or printer via the Number of Printers/Port Assignment. Computers connect to computer ports. Printers and plotters connect to printer ports. On all models, a minimum of one port must be assigned as a printer port and a minimum of one port must be assigned as a computer port.
# To select a printer in multiple printer applications, the computer sends the Printer Select Code (which consists of any ASCII character string numbering from one to eight characters) followed by the desired printer port number. The Printer Select Code is trapped by Print Master if it is valid and not passed to the printer.
# NOTE: This section is not applicable to the 706A or 708A models. Print Master will translate for serial devices using different configurations. You may set the baud rate, word size, stop bits, parity and XON/XOFF for each individual serial port. The available values for these parameters are listed in Section 2 (Specifications). Factory default configuration on all serial ports is 9600 baud rate, 8 word size, 1 stop bit, no parity and XON/XOFF disabled.
" # # You may configure Print Master to print a programmable message and the logical name of the source computer on a separate sheet of paper before printing any other data. You may enable or disable the Header Page Message for each individual computer port. Factory default is: This print job is for:, with the Header Page Message disabled.
Please see the table below for a quick reference to the printer sharing operating procedure. PRINTER SHARING QUICK REFERENCE Item See Section Sharing a single printer 6.2.1 Specified sharing of multiple printers 6.2.2 Contending for multiple printers 6.2.3 Buffering of print data 6.2.4 Beginning and ending a print job 6.2.5 Buffer clearing 6.2.6 Minimum size print job 6.2.7 Port selection methods 6.2.8 Full duplex communication 6.2.9 Plotter sharing hints 6.2.
# To select a specific printer in multiple printer applications, you must send a specific printer select sequence which consists of the Printer Select Code (factory set is $PRINTER) followed by the desired printer port number. The Printer Select Code and port number are trapped if valid and not passed to the printer. The printer port number then becomes the printer assignment number for your computer port.
There are two modes for sending the Printer Select Code. In Printer Select Mode 2 (printer selection anytime while printing), Print Master looks for the Printer Select Code any time. If no Printer Select Code is received, the data will be routed to the default printer. In Printer Select Mode 1 (printer selection at beginning of printing), Print Master looks for the start of the Printer Select Code in the first 16 characters received.
When a user sends a print job, the data is stored in Print Master's spooling buffer (1 MB standard, available with 2 MB on 700C, 700D and 700E models; available with up to 4 MB on 700A models). All users may simultaneously send data to this dynamically allocated buffer. Therefore, the entire buffer could be occupied by data from one user if only one user is active or the buffer could be simultaneously distributed to all users.
4. The computer sends the Printer Select Code followed by a printer port number. If the port number is the same number as that of the current print job, this will indicate the end of the current print job, and the next print job will be routed to the same printer. If the port number is a different number from that of the current print job, this will indicate the end of the current print job, and the next print job will be routed to the newly selected printer.
If you wish to clear a print job is sent in error, you must send the clear buffer sequence which consists of the Printer Select Code followed by CLR. This command will only affect print jobs originated by your computer. Print jobs in the buffer from other computers are not affected. The clear buffer sequence will clear the most recent print job sent to Print Master from your computer.
" # BayTech provides utility software which allows you to conveniently select between peripherals for IBM DOS and Microsoft Windows applications. Port selection is as easy as activating hot keys or by using a mouse. Please see Section 4.2 for more information. There are alternative methods to peripheral selection. One method is to make the port select sequence the first characters of the text. These characters will be trapped by Print Master and not sent to the printer.
Programs such as Word Perfect and WordStar typically send a printer initialization string before any data. You may imbed the port select sequence 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. The port select sequence for the Print Master would typically be inserted prior to any escape codes for the printer.
It is still possible to plot dynamically through Print Master if required. When plotting in this fashion, you would probably need to increase the input inactivity timeout value to a higher number than factory default (20 seconds). Plotting dynamically would not allow you to utilize the buffering capabilities of Print Master because the data stream from the computer is not continuous.
# # # COMPUTER-TO-PRINT MASTER-TO-PRINTER COMMUNICATION When a computer transmits data to a printer through a Print Master computer port, the data is received and stored in the buffer which in turn retransmits it to the printer through a printer port.
PRINT MASTER-TO-COMPUTER COMMUNICATION NOTE: Print Master will provide full duplex communication between a computer and printer which are connected through the unit. This section is applicable only when a device that is connected to a printer port is sending data back to a device connected to a computer port. When Print Master is sending data to a computer through a computer port and the computer cannot receive any more data, Print Master will expect to see a low on the DTR line.

Configuration changes are made through the master configuration port which is the highest numbered port on all models. Print Master will transmit configuration menus to the serial device connected to the master configuration port on all models except the 706A and 708A. The 706A and 708A will print out configuration menus on a parallel printer connected to Port 1 as described in Section 7.1. If you are configuring a 700C unit, please see Section 7.2.
All ports on the Print Master 706A or 708A must be inactive (i.e., only the green power LED should be illuminated). With the PARSEND or MS BASIC program loaded on your PC, send from the keyboard Control-T followed by capital C. These characters will not print on the printer. The Model 706A or 708A will respond with the main configuration menu which should print out on your printer. When configuration mode is been accessed, all the red LEDs on the front panel will illuminate.
" Print Master 706A and 708A will respond to the receiving of Control-T and C by sending to the printer on Port 1 the following identification block and a menu of the configuration options available: Bay Technical Associates Model 706A Print Master Copyright 1989 Revision 3.00 Total Memory : 1024K Bytes Status.......................................1 Change Logical Name..........................2 Set Input Inactivity Timeout.................

All configuration changes must be made through the master configuration port. This master configuration port has access to all options of the configuration mode. Please use the following procedure to configure your Print Master 700C model: 1. Connect a dumb terminal (or a PC running a terminal emulation program) to the master configuration port which is Port 6 on the 706C, Port 8 on the 708C, Port 10 on the 710C.
If you do not have a dumb terminal or a terminal emulation program, BayTech supplies a utility diskette which includes software to put an IBM PC or compatible into a terminal mode. See Section 4.2 for instructions to obtain the software (TERM.EXE) by running the INSTALL.EXE program if you have not already done so. Once you have obtained TERM.EXE, use the following procedure: 1.
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. Depress function key: F1. NOTE: The F1 key in TERM sends the character sequence Control-T (14 Hex) followed by the capital C character (43 Hex).
By responding to the Enter Request: message at the end of the main configuration menu with "1" (Status), you may review the status of the current configuration of Print Master.
By responding to the Enter Request: message at the end of the main configuration menu with "2" (Set Serial Port Configuration), you may change the serial configuration of each port (i.e. baud rate, word size, stop bits, parity, and XON/XOFF). Each port may be configured individually. This allows Print Master to translate for devices using different configurations. You may also assign or change the Logical Name for each port.
You may now reconfigure Port 5 by selecting the appropriate option from the menu. For example, to change the baud rate to 2400 baud, send character "2" (Set baud rate).
CAUTION: If Y is sent before changing the configuration device to the new configuration (baud rate or parity), Print Master will not receive the Y response. However, you will be locked out of Print Master. If this occurs, recycle Print Master power. Print Master's configuration will default back to the last saved configuration. You must then re-enter configuration and re-save the configuration of the configuration port.

) ( ! ! Option 19 allows up to nine (9) Print Master 710C, 710E or 710F models to be cascaded allowing you to increase the number of available ports. All 710 models with Option 19 may be cascaded together. The primary difference in 710 models with Option 19 versus standard 710 models is the incorporation of a Unit ID Number.
( Print Masters equipped with Option 19 (Cascade Option) are configured exactly as described in Section 7.2 or Section 7.3 of this manual with the exception of SET UNIT ID NUMBER. Each 710 Print Master with Option 19 is configured individually through Port 10. During operation, Port 10 is typically used to cascade to another Print Master. Therefore, you should make the necessary configuration changes to each unit prior to cabling the units together.
( When the computer connected to Port 10 of a 710 model with Option 19 accesses the configuration mode by sending Control-T followed by capital C, Print Master will respond with an identification block and main configuration menu similar to the following: Bay Technical Associates Model 710E Print Master with Option 19 Copyright 1986,1987,1988, 1989 Revision 3.00 Total Memory : 0512K Bytes Status........................................1 Set Serial Port Configuration......
( By responding to the Enter request: message at the end of the main configuration menu with "1" (Status), you may review the current configuration status of Print Master.
( By responding to the Enter request: message at the end of the main configuration menu with "A" for models 710E and 710F or "9" for model 710C (Set Unit I.D. Number), you may set the Unit ID number which is used to determine which unit in the cascaded chain a print job will be sent to. NOTE: Units do not need to be numbered in numerical sequence.
( To cable Print Masters equipped with Option 19 together, connect Port 10 of a 710 having a lower Unit ID Number to port 9 of a 710 having a higher Unit ID Number with a male-to-male crossed cable (BayTech part number MM09XYYY, where YYY is the required length). The required pinout is shown in Figure 3 on page 18.
The Unit ID Number and the printer port number then become the default unit and printer assignment numbers for that computer. All subsequent print jobs sent without a printer select sequence will be sent to this unit/printer port by default. If you desire to send print jobs to the same printer, the Printer Select Code, Unit ID Number, and printer port number do not need to be sent again.
) # Please check this troubleshooting guide before calling BayTech Tech Support. NOTE: This troubleshooting guide is geared towards the IBM PC family and compatibles. The term "PC" as used below refers to any IBM PC, AT, XT or compatible. PROBLEM: DATA DOES NOT PRINT SYMPTOM: NO PORT LEDs ILLUMINATE CAUSE: PC serial cable or COM port. SOLUTIONS: 1) Check cabling between PC and Print Master. 2) Check handshaking lines using TERM program.
CAUSE: Print Master is connected to non-designated COM port. SOLUTION: Make sure Print Master is connected to designated PC COM port. Check using TERM program. Turn Print Master off and you should not see CTS/DSR lines toggle if you are on a non-designated COM port. CAUSE: PC is connected to Print Master port which is configured as an printer port. SOLUTION: Enter Print Master's configuration mode and in the Status menu, check the port's assignment.
PROBLEM: DATA DOES NOT PRINT SYMPTOM: PC AND PRINTER PORT LEDs ILLUMINATE CAUSE: Printer cable. SOLUTION: Use the correct parallel or serial cable between Print Master and printer (see Appendix A). CAUSE: Printer is off-line. SOLUTION: Make sure printer is on-line CAUSE: Serial parameters do not match between Print Master and computer or printer. SOLUTION: Verify the serial parameters match between the computer and Print Master and between Print Master and the printer.
PROBLEM: PRINTS GARBAGE SYMPTOM: MISSING CHARACTERS CAUSE: Incorrect printer cable type. SOLUTION: See Appendix A for correct pinouts between Print Master and printer. Check handshaking. A way to check is to force an error condition at the printer (i.e. remove paper tray from laser printer or turn off-line with power still applied). Send print job to printer. If printer LED goes off, you can conclude no handshaking was done.
SYMPTOM: RANDOM GARBAGE CHARACTERS CAUSE: Serial port configuration. SOLUTION: In Print Master's configuration mode, match baud rates, word size, stop bits, parity, and handshaking with the connected serial device(s). CAUSE: Cable length. SOLUTION: If using serial cable, length should not exceed 150 feet. If using parallel cable, length should not exceed 15 feet. Use shorter cable.
CAUSE: Software. SOLUTION: Use dumb terminal or a PC running a terminal emulation program (e.g, TERM supplied by BayTech or another program such as PC Plus). CAUSE: User activity. SOLUTION: Wait until current activity between PC and printer is completed. There should be no red LEDs illuminated when trying to configure. CAUSE: Bad PC COM port. SOLUTION: Try a different COM port or PC. CAUSE: PC serial card uses incorrect interrupt.
CAUSE: You are in Printer Select Mode 1 with zero (0) timeout. SOLUTION: Switch to Printer Select Mode 2 or increase timeout, both via configuration mode. NOTE: Any select sequence will not be recognized after 16 characters in Printer Select Mode 1. SYMPTOM: SOME SORT OF PRINTER SELECT CODE PRINTS ON DOCUMENT. CAUSE: Printer Select Code sent does not match Printer Select Code configured in Print Master. SOLUTION: Match the Printer Select Code sent exactly with that configured in Print Master.
CAUSE: Characters used in Printer Select Code are too common and may inadvertently appear somewhere in print job. SOLUTION: Change Printer Select Code to a unique character sequence. PROBLEM: PRINT JOBS INTERMIX CAUSE: Timeout period is too short. SOLUTION: Increase input inactivity timeout period via configuration mode. PROBLEM: PRINT MASTER DOES NOT TIMEOUT CAUSE: Timeout is set to zero (0). SOLUTION: Increase input inactivity timeout period via configuration mode.
PROBLEM: HOT KEY SOFTWARE HANGS UP PC WHEN EXECUTED. CAUSE: LPTX not rerouted for serial communication. SOLUTION: Reroute LPTX using this command: MODE LPTX:=COMX. X=1, 2 or 3. CAUSE: Floating condition on DSR or CTS lines. SOLUTION: Use the TERM program to check handshaking lines. Power down Print Master. If DSR, DCD and CTS lines do not toggle, check computer cable (see Appendix A).
