INTRODUCTION The Epson 3270 coax interface card C82314* with PC auto parallel sharing port is an optional Epson interface card. It allows the direct connection of supported Epson ESC/P dot matrix and laser printers to a coax type-A adapter of an IBM 3174/3274/3276 Control Unit or IBM 3270 mainframe system. In addition, a Centronics compatible mini-parallel port with auto switching allows a PC or alternate host to share the printer with the 3270 host for optimum printer utilization.
GENERAL SPECIFICATIONS Input Protocol: IBM 3270 coax LU1 or LU3 protocol and Centronics parallel protocol Output Protocol: Epson parallel, internal interface connection Receive Data Rate: Maximum burst: 2.3587 million bits/second Data Buffering: 4K byte coax communication buffer Language Support: Standard IBM 3174 language sections (See Appendix A, Command 8 for list of languages.
BUTTON SPECIFICATIONS Button Functions Top PA1 response when the PA red LED is on Prints out a page listing when pressed and held for 2 seconds. If the coax cable is disconnected, then a RAM/ROM self test is also performed and the results are printed.
INSTALLING THE INTERFACE CARD Install the coax interface card in the same way as any Epson optional interface. This procedure is explained in detail for the individual Epson printers in either an appendix or the section on Using Printer Options in the user’s manual that comes with the printer. Please follow the instructions carefully to install the coax interface card. Secure the interface with the thumb screws.
INTERFACE CONFIGURATION After installing the interface card and performing a self-test, the interface is ready to operate in most environments. The factory default settings will be satisfactory for most programs and applications. Be sure to check Command 60 on the self test print out to confirm that the interface is configured correctly for either a dot matrix or HP laser printer.
If a coax host Is not available and basic setup selections need to be changed, the interface has the option of a push button setup as defined in Appendix B. This option enables the basic interface features and RPQ options to be selected.
to’access all of the Epson features such as color printing, superscripts; and subscripts. Command-Pass-Thru is accomplished by converting the printer command sequence into a series of two digit hexadecimal values. For example, an Escape has a decimal value of 27 and a hexadecimal value of 1B. In Command-PassThru, an Escape is the character ‘1’ followed by the character ‘B’.
Valid characters for hex codes are 0-9 and A-F (upper case letters only). No spaces are allowed in the command between the ‘delimiter sequence &% and the first hexadecimal value. A single space is permitted, but not required, to separate pairs of hexadecimal letters (to aid in easier interpretation of the hex codes). If an error in formatting the command sequence occurs, the interface will resume printing at the point in the sequence where the error occurs.
Another method of Transparent Data Transmission is the Xerox defined SCS TRN code 36. Generally accepted for use in laser printer applications, this method is the same as the Coax Interface non-translate method above. Control code sequence rules are the same for SCS code 36 as for code 35. ALTERNATE HOST (PC) AUTO PARALLEL SHARING If the C82314* is connected to a PC with the parallel sharing cable, the PC must be turned on.
PARALLEL INTERFACE SPECIFICATION The C82314* coax interface provides a Centronics parallel data input port to allow automatic sharing of the Epson printer between the 3270 host and an alternate host. The parallel interface was designed to be compatible with popular printer interfaces found on personal computers.
Parallel Cable Pin Direction Description BUSY 11 OUT A HIGH signal indicates that the printer cannot receive data. The signal goes HIGH in these cases. -Data entry, for each character -When off line or in error slate -When serving the IBM host and a byte of parallel data is received. PE 12 OUT HIGH when the printer is out of paper. 13 SLCT 13 OUT Pulled up to +5V through a 3.3K ohm resistance.
Signal Parallel Cable Pin Direction Description 31 INIT 16 IN Defined to reset and dear the printer when LOW; THE RESET AND CLEAR ARE NOT SUPPORTED BY THE C62314*, As the IBM host cannot be interrupted by this signal. An ACKNLG is generated for handshaking. 32 ERROR 15 OUT This signal goes LOW when the printer is in an error state such as out of paper. 33 GND 25 34 NC 35 HIGH 36 SLCTIN Signal Pin NOTE: Return Pin Logic ground Not used Pulled up to +5V through a 3.
Data transfer is carried out by observing the ACKNLG or BUSY signals. Data transfer to the printer occurs only after receipt of the ACKNLG signal or when the BUSY signal is LOW. TIMING DATA IN - \ / / \ .5usec .5usec .5usec min. min. min. STROBE BUSY -I I Approx. 7usec min ACKNLG II Approx. 5usec. I Data must be present a minimum of 0.5 microseconds before and after a minimum 0.5 microsecond STROBE pulse.
HP FONT IDENTIFIER CODES When Command 60 (see Appendix A, command 60) of the interface is used to select HP LaserJet emulation, font changes can be accomplished by simply including the font identifier ID code in the text of the document being printed. In the Appendix C at the back of the manual is a summary listing of the font identifier codes for the printer’s resident fonts and the Epson font cartridges.
COMPUTER OUTPUT REDUCTION (COR), HP EMULATION The landscape printing capability of the HP LaserJet emulation enables the interface to automatically print traditional data processing reports requiring 66 lines by 132 columns or 198 columns of data on 8.5 x 11.0 inch paper.
AUTOMATIC PRINT ORIENTATION (APO), HP EMULATION When Automatic Print Orientation (APO) is specified active (see Appendix A, command 61), the coax interface notes the page format parameters of the print image and calculates the required print dimensions in inches.
regardless of whether the user specified a portrait font ID. You should be aware of the significance of the specified form size (as defined by the MPP and MPL) and select these values in accordance with your desired orientation when APO is active. PAGE ORIENTATION LOGIC The page orientation logic is as follows depending on whether APO in Command 61 is active and the Paper Tray Orientation selections made in Commands 62 to 64.
APPENDIX A: HOST DOWNLOAD CONFIGURATION COMMANDS This appendix defines the configuration commands which may be used to select setup values for the printer interface. These commands may be sent to the printer as part of a normal 3270 coax print job or hard copy print screen. The interface will identify the commands and obey their instructions without printing the text of the command. If the text of a command prints, check that the format of the command is correct.

COMMAND 1: BUFFER SIZE Selects logical default buffer size VALUE DESCRIPTION 1 *2 3 4 5 960 characters 1920 characters 2560 characters 3440 characters 3564 characters NOTES: This command, along with the ‘Z99,0’ command, changes the logical buffer size selection in the non-volatile memory of the interface. The logical buffer size is only reported to the host the next time the unit is powered up. The physical buffer size is permanently set at 4K. EXAMPLE: &%Z1,3 Sets logical buffer size to 2560 characters.
COMMAND 3: CHARACTERS PER INCH Selects default CPI VALUE DESCRIPTION 0 *10 12 15 16 NOTE: No default sent to printer 10 CPI 12 CPI 15 CPI 16.7 CPI The IBM host controls CPI unless Command 36 is used to select override of host CPI commands.
COMMAND 6: MAXIMUM PRINT POSITION Selects current and default Maximum Print Position, the maximum number Of characters which can be printed on each line. VALUE DESCRIPTION 000 Infinite Line Length 001 to 255 Set MPP in number of characters * 132 (Factory Default) NOTES: Normal values are 80, 132, or 198 characters. This default emulates the front panel selection on an IBM printer, MPP and the current position will not be changed by changes in CPI.
COMMAND 8: LU1 LANGUAGE Selects default LU1 Language. VALUE DESCRIPTION * 01 03 04 05 06 07 08 09 10 11 12 (same as 11) 13 14 15 16 17 (same as 16) 19 20 21 22 23 (same as 07) 24 (same as 09) 25 (same as 01) 26 (same as 08) 27 (same as 10) 28 29 (same as 06) 30 (same as 11) 31 (same as 14) 32 (same as 14) English (U.S.) EBCDIC Austrian/German Belgian Brazilian Canadian (French) Danish/Norwegian Danish/Norwegian (alt.)

COMMAND 9: FONT SELECT (Matrix Printer] Selects Epson default font when dot matrix printer protocol is selected in Command 60. This command is not functional when laser printer protocol is selected.
NOTES: This command defines the default paper source for the Page Presentation Media (PPM) Host command in SCS mode. If the PPM command is received from the host, the interface always sends the SCS mode paper source command to the printer unless values 0 or 1 are selected. If the printer does not have a secondary paper bin or anenvelope feeder, it ignores the command, but it will be used for Commands 62-64 logic.
COMMAND 13: FORM FEED AFTER LOCAL SCREEN COPY Specifies whether a Form Feed is performed after a local screen hard copy. VALUE DESCRIPTION *0 No Form Feed after local screen hard copy Form Feed performed after local screen hard copy 1 NOTES: To use this function, the RPQ should be: IBM 3268 RPQ SC9508 IBM 3287 RPQ MC3750 IBM 4214 OPT 20=3 This command only affects the local screen copy, not the host-initiated local copy printing.
Command 14, Values 0 and 1 are only functional from CUT terminals. EXAMPLE: &%Z14,3 Prints true screen image In non-SCS print and local copy COMMAND 15: CR at MPP + 1 Sets the printer in accordance with the RPQ installed in the control unit.
COMMAND 17: VALID FF FOLLOWED BY DATA Sets the printer in accordance with the RPQ installed in the control unit VALUE DESCRIPTION *0 1 Second print position of first line on next form First print position (PP) of first line on next form NOTES: For the Value 1 selection, the RPQ would be: IBM 3268 RPQ SC9503 IBM 3287 RPQ N/A IBM 4214 OPT 16=2 Available only in non-SCS operation EXAMPLE: &%Z17,1 Performs first PP of first line on next form as the next PP when a valid FF (positioned anywhere but the end of
COMMAND 19: FF VALID LOCATION Sets the printer in accordance with the RPQ installed in the control unit VALUE DESCRIPTION *0 FF is valid only at the first print position or at position MPP+1. 1 FF is valid anywhere it occurs. NOTES: To use this function, the RPQ should be: IBM 3268 RPQ SC9506 IBM 3287 RPQ SC3739 IBM 4214 OPT 19=1 Available only in non-SCS operation.
COMMAND 25: FORM FEED USAGE Enables a Forms Feed from the host system to be converted to the required number of line feeds (beneficial when forms length is controlled by the interface). VALUE DESCRIPTION 0 Pass FF from host to the printer (Laser Printer default) *1 Count the lines in Command 5 and send multiple line feeds to the printer in place of the host FF. EXAMPLE: &%Z25,1 Sets the printer to count the lines specified in Command 5.
VALUE DESCRIPTION *0 1 No extra FF is sent Send FF after time out value NOTES: The time-out value is the same as the time-out used to switch between host and alternate host printer sharing. (See Command 51) Generally, the host application generates a termination FF, and there is no need to change this command from the default. In duplex printing, the last page will be ejected. EXAMPLE: &%Z27,1 Sends FF after time delay selected by command 51 (default = 10 sec.
COMMAND 34: INTERVENTION REQUIRED (IR) TIME OUT Sets the time interval before an intervention required signal is sent to the host after a printer error occurs. VALUE DESCRIPTION 000 Never send an IR 001 to 255 Send IR after the VALUE times 5 seconds after printer error occurs. * 120 Default, send IR after ten minutes.
COMMAND 36: SUPPRESS IBM CONTROL CODES This function is used to select suppression of all or some IBM control codes sent from the host system. VALUE DESCRIPTION *0 Obey all IBM control codes 1 Suppress all IBM control codes 2 Suppress only LPI and CPI control codes 3 Suppress only CPI control codes 4 Suppress only LPI control codes 5 Suppress print quality specified in the PPM command.
COMMAND 38: TRUE LPI SPACING (LASER) Because laser printers have a non-printable border around the edge of singlesheet pages, 6-LPI and 8-LPI spacing is compressed slightly to enable 66 lines and 88 lines to be printed on 11-inch long paper. This can occasionally cause a problem, especially with preprinted forms. Command 38 enables a user to override the normal laser printer LPI compression.
COMMAND 41: COMMAND ID CHARACTER Specifies the character which can be used for the command identifier (in place of "Z" which follows the ‘Lead In’ characters. VALUE DESCRIPTION *5A ZZ NOTE: Makes Z the command character. ZZ is the ASCII HEX value of the command ID character. The character selected must not be 0 through 9 or A through F (valid hex values), or L, P, U.
COMMAND 45: SCS TRN TRANSLATE Specifies how transparent data sent using SCS code 35 is handled. VALUE DESCRIPTION 0 *1 Binary Transparent Emulate IBM 3287 Printer NOTES: Value 1 causes valid graphic characters to be printed normally (i.e., converted from EBCDIC to ASCII), control codes and invalid graphics to be printed as hyphens, and normal page formatting is maintained. Value 0 causes the 8 bit binary codes to be sent directly to the printer just as they are received from the host.
Because the printer is being shared between the parallel port and the 3270 host, careful attention should be paid to setting up the PC so that jobs are not automatically terminated because the printer is. busy. This problem may be helped by setting the PC timer “off by writing "mode 1pt1:,,p" (in case of an LPT1 printer) in DOS. Use of the DOS PRINT command or a spooling program for the PC is recommended.
COMMAND 55: CUSTOM USER STRINGS Allows a coax user to define up to six custom user strings, of up to 25 bytes each, which are stored in the memory of the interface card and sent to the printer whenever the “two-letter delimiter, letter U, and number of the string’ appears in the text of the document, i.e. &%U3. VALUE DESCRIPTION 0 to 5 Following the value number, insert a parenthesis, followed by the ASCII hex bytes included in the user string, and then a parenthesis to end.
COMMAND 56: SHARED PORT INlTlALlZATlON STRING Allows the user to define an initialization string of up to 25 bytes which are stored in the memory of the interface card and sent to the printer at the beginning of any printing received from the alternate shared port. VALUE DESCRlPTlON 1 Following the value number, insert a parenthesis, followed by the hex bytes included in the command string, and then a parenthesis to end.
NOTES: To aid in readability, a single space is allowed between hex bytes but is not included in the string. The coax port initialization string is only sent to the printer when you turn the printer on and after printing by the shared parallel port has occurred. Host SCS commands and download commands have priority over the initialization string instructions. To change the initialization string simply input the new command values. The entire old string is automatically erased.
COMMAND 61: AUTOMATlC PRINT ORIENTATION (APO) (LASER) Laser printers automatically control page orientation if the user decides to activate auto print orientation (APO). Refer to the page orientation logic chart in the computer output reduction section of the manual. VALUE DESCRlPTlON *0 1 NOTE: Auto Print Orientation (APO) is ACTIVE. The page dimensions of a document are checked to determine if the data should be printed in landscape because the width is greater than the length.
3 User Defined mode; documents are printed using the fonts and orientation that the user specifies through use of the &% font ID commands. EXAMPLE: &%Z62,3 Specifies that the document is printed as formatted when the primary paper tray is specified as the paper source. COMMAND 63: ALTERNATE PAPER TRAY ORIENTATION (LASER) This command functions identically to Command 62 except it controls the orientation for printing that specifies (SCS,LU1) the alternate tray for the paper source.
EXAMPLE: &%Z64,1 Specifies all printing performed using paper from the manual feed slot be printed in portrait orientation. COMMAND 65: CHARACTER SET SELECTION Enables the user to make a special selection of the ASCII character set that is used in the conversion from EBCDIC (SCS/LU1) or DSC (LU3) to ASCII. This is the character set that the printer uses in printing. It must be selected at the printer by using the front panel or dip switches of the printer.
NOTES: Previously stored substitutions are automatically changed to the new selection when the same hex location is specified in the EBCDIC table. Previously stored substitutions are cancelled if an ASCII hex sequence of 00 is specified. Command ‘Z99,0’ must be used to store the substitutions in NV Memory for them to be effective when the printer is next turned on. The active EBCDIC (SCS/LU1) translation table prints out at the end of the interface self-test summary.
VALUE DESCRIPTION 0 Restores the factory defaults to the NV memory of the interface. 1 Prints out the active setup selections for review by the user. 2 Restores the setup selections stored in the NV memory to active status of the interface. NOTES: The active setup selections are the same as the NV memory selections if no host download commands have been sent to the printer since it was turned on.
APPENDIX B: PUSH BUTTON SETUP Push button (Yes / No) setup provides an alternate method for a user to select the basic configuration selections for the printer emulation. Selections can also be changed by the Host Download Configuration Commands as specified in Appendix A which has more detailed information on the selections.
