    ADDRESSING VI. ADDRESSING Each channel of the DS-2000 uses 8 consecutive I/O address locations. The base addresses are independen t but must begin on an even 8-byte boundary (xxx0H - xxx7H or xxx8H - xxxFH). The numbers xxx are controlled by th e Programmable Option Select (POS) and address decoders t o provide complete 16-bit addressing for each c ...

    PROGRAMM ABLE OPTION SELECT The remaining POS registers are used for address and interrupt selections. These registers are programmed by the user through the IBM installation utility supplied with the PS/2. These registers are read/write but should not be written to by user software. The bit definition s of these registers are given in figures 16(a ...

    OUT PUT CONFIGURATIONS IX. OUTPUT CONFIGURATIONS Two sets of jumpers are implemented on the DS-200 0 to control the auxiliary driver/receiver set. Jumpers J 2 and J3 perform identical functions on channels 1 and 2 respectively . The function of J2 and J3 is to control the source of the data exchanged on the auxiliary communication lines. The output ...

    OUTPUT CONFIGURATIONS The other function of J2 and J3 is to configure th e communication channel in half or full duplex mode. Hal f duplex operation is achieved by connecting pins 4 and 8 of the jumper block (figure 23). This allows th e transmitter to be enabled and disabled using the data terminal ready (DTR) output in the modem contro l register ...
