Figure 5-12, Digital Outputs Setup Menu
This menu, shown in figure 5-12, is used to control the 8 TTL lines of the rear panel
digital output port, used for controlling external equipment.

Decimal

The bit pattern appearing at the digital output port is set by an unsigned eight-bit
binary number, the decimal equivalent of which can range from 0 to 255. This
decimal value may be set using the left-hand display, so that for example if it were 0
the eight output lines would all be low, whereas if set to 255, then they would all be
high.
The centre of the right-hand display shows the number in binary format, with the
value of each bit shown below its bit number. Each of the keys around this display
will toggle one bit, as indicated by the numbers adjacent to them, providing a second
way of controlling the port.
Any changes made to the digital output in decimal format will be reflected in the
binary display and vice-versa.
