Using the Parallel Port

7-7

Using the Numeric (Run) Mode

In this mode, the DL5 interprets inputs into the parallel port only as BCD
numeric data and immediately displays the BCD number. Only line 1 of the
DL5 is used. Inputs to the first twelve terminals (D0 through D11) are
always interpreted as three BCD digits. Inputs to the last four terminals
(D12 through D15) are interpreted as a fourth BCD digit (if the input is a
valid BCD code), or as a special instruction code (if the input is not a valid
BCD code). The special instruction code allows you to define a destination
on the DL5 display for the three BCD numbers on data lines D0 through
D11. This allows a number as large as 15 digits, two 6 digit numbers, or
three 3-digit numbers to be displayed on the DL5. The table below defines
the special instruction codes of D12 through D15.
