Connecting The MPS 1000 To Your Computer Now that the test pattern has shown that your printer is working well, it's time to hook it up to your computer. Turn off the printer and the computer when you do this. Your printer is designed to connect directly by cable into your com- puter through either the serial port (six pins) or the parallel port (double-row of 36 pins). lllIIDII Figure 1- 18. Printer Connections CAUTION: • When the MPS lOOO's serial port is selected, any cable connected to its parallel port MUST be disconnected. When the MPS lOOO's parallel port is selected, any cable connected to its serial port MUST be disconnected.
An important feature of the MPS 1000 is its ability to print in two modes of operation: Commodore and IBM 5152 Plus. In its Commo- dore mode, the MPS 1000 can print Commodore business fonts and graphics. In its IBM mode, the MPS 1000 is able to produce characters in two different styles. Type selection is discussed fully in Chapter Four. As delivered from the factory, the MPS 1000 set is in Commodore mode. To perform in its IBM-compatible mode, the DIP switch 1-1 located in the rear of the MPS 1000 must be changed from its OFF position to ON. DIP switch 1-3 selects the interface: ON for serial port and OFF for parallel. See Appendix C for its precise location. 18
