[. . . ] (7) SW1-8: When this switch is set to the OFF position, SLCT IN signal is not fixed internally, thus permitting the Printer to be controlled from a host computer. NOTE: This signal line is wired O Red with the pin No. Therefore, to control the signal level with the pin No. 36 of the interface connector from the external CPU through TTL, etc. , leave this DIP switch pin to the OFF position. -45- (8) Character sizes and maximum column lengths can be specified as follows; Table 3 Character Size and Maximum Column Length Character size Normal Condensed Emphasized Pin number SW1-3 OFF OFF ON SW1-4 OFF ON ON Maximum column length 80 132 80 Default length 80 132 80 If you turn any of the above character sizes to the enlarged character print mode, then the maximum column length will be reduced to a half of them. 5. 2. A summary of the functions of the respective DIP switch pins and their preset conditions at the time of shipment are shown in Table 4. Table 4 Functions and Conditions of DIP Switch No. 2-1 2-2 2-3 2-4 Function International character set International character set AUTO FEED XT signal internally fixed or not fixed 1 inch skip-over perforation OFF ON See Table 5. Not fixed Valid Fixed Invalid OFF ON Factory-set condition (1) SW2-1 & 2-2: Combined use of these two pins and SW1-7 permit selection of the international character set for U. S. A. , France, Germany, England, Denmark, Sweden, Italy, and Spain as shown in Table 5 upon power application. (2) SW2-3: This pin is used to fix AUTO FEED XT signal internally. (Refer to the explanation of control code "CR" in paragraph 3. 1 (1) "WHAT IS THE MX-80 TYPE II?". ) This signal line is wired ORed with the pin No. 14 externally through TTL, etc. , leave this DIP switch pin to the OFF position. (3) SW2-4: This pin is used to set the automatic skip-over perforation function. (a) When this pin is set to the OFF position, the automatic skip-over perforation function becomes valid. By this function, the paper automatically advances to the first line of the next page when the remaining page length is 1 inch. (b) When this pin is set to the ON position, the l-inch automatic skip-over perforation function becomes invalid. However, you can activate this function programmably (described in detail later). -46- 5. 3. Coding tables Appendix 3 shows all available codes when the Printer is set for operation with standard coding by setting the DIP switch pins l-7, 2-l and 2-2 all to ON position. Table 5 shows International Character Set Designation according to the combination of the DIP switch setting. Table 5 International Character Set Designation The above settings can be changed to any country character sets by inputting ESC R + n control codes. (Described later. ) The above countries' characters are addressed as per the following table. Table 6 International Character Sets -47- 5. 4. Setting sequence of functional specifications The MX-80 Type I I has a choice of various functional specifications such as amount of line spacing, form length per page, number of columns per line, automatic skip-over perforation, etc. for selection under the control of both hardware (DIP switches) and software (control codes) which is described later. 56 through 59, setting sequence of these functional specifications are illustrated. Fig. [. . . ] (Data transfer to this printer can be carried out only after confirming the ACKNLG signal or when the level of the BUSY signal is "LOW". ) -88- (4) Data transfer sequence Fig. A2-1 shows the sequence for data transmission. Relations among the ON LINE switch, SLCT IN signal, DC 1/DC 3 code and interface signals are shown in Table A2-2 below. Table A2-2 Relations among ON-LINE, SLCT IN, DC 1/DC 3 and Interface Signal -89- NOTES: 1. In Table A2-2, it is assumed that as soon as the Printer receives data, it sends back the ACKNLG signal, though this data is not stored in the print buffer. In this status, the Printer is waiting for the DC 1 code for normal entry. [. . . ]
