The AUX Output
The analog signal present at the SDA 601 AUX output is derived
from the Serial Video input. It is a single channel, 5-bit decoded and
unfiltered, suitable for identifying the input and displaying the cursor
cross hairs, Highlighting, and OSD.
The AUX choices in the I/O menu are: Pixmon Y; Pixmon R–Y; and
Pixmon B–Y. As you might guess, this determines which of the three
video components is shown on the video monitor. The behavior and
appearance of the cross hairs, Highlighting, and OSD are not af-
fected by this choice.
RS-232 Connector
The RS-232 connector is 9-pin subminiature D-type connector that
provides a serial interface for printer output and eventual in-field
software upgrades. It has a driver built in for RS-232 serial binary
data interchange. The operational mode is full duplex; data type is
asynchronous. Baud rate and parity are selected throuth the Utility/
RS232 Setup submenu; see page 32. The pin assignments are listed
in Table 1.
