Printronix LQH-HWTM Using the Evfu, Evfu Codes PI Line Enabled, Data Bits Channel Hex Dec Code

Using the EVFU

3.Data bit 5 must be 0 (not set).

OR:

1.The PI line must be disabled or low;

2.Bits 7 and 6 must be 0 (not set); and

3.Data bit 5 must be 1 (set).

Given these conditions, the lower four bits of a byte specify the EVFU channel number. Table 25 lists the EVFU channels and their equivalent data bytes when the PI line is enabled; Table 26 lists the EVFU channel and their equivalent data bytes when the PI line is disabled.

Note *The ASCII values in Table 25 assume that all undefined bits are set to 0. When the PI line is enabled, data bit 8 is the PI line on a serial interface, and data bit 8 is undefined on a parallel interface.
