The APD-250M060 monitor consists of 250 character
DC plasma display panel, drive circuitry, display controller,
audible alarm, enclosure and illuminated control panel. The
enclosure may be mounted on a flat surface or in a sus-
pended configuration. Its large characters, wide viewing
angle and high brightness (with an auto or manual bright-
ness control) provides excellent visibility in a wide range of
ambient light conditions from total darkness to bright
sunlight.
Interfacing is via RS-232D at 9600 baud with no handshak-
ing (a FIFO buffer is used to capture data when the display
is busy). The byte format is 1 start bit, 8 data bits and 1 stop
bit. As each monitor receives a data byte, it automatically
sends it to the next unit in the daisy (up to 8 monitors
maximum) chain. Returning data from the monitors are
handled in the same way. A front panel bypass switch is
provided to allow the operator to instantly route the input
channel to the output channel in the event of a monitor
failure.
Single byte and two byte commands allow simplified code
generation, yet accomplish complex display tasking such as
scrolling or inserting lines and characters. The character
generator is an 8K x 8 bit EPROM which has capacity for
two 256 character sets. It is preprogrammed with two ASCII
character sets (128 characters each including control
codes). Other character sets may be factory programmed
per the user’s special requirements.
The audio alarm operation is under the complete control of
the host system. The alarm is a warble of two tones which
can be user adjusted. The volume may be adjusted by the
operator from 65 to 85 dbA by a front panel control.
User controls are power, self test, auto/manual brightness
adjustment, I/O bypass, alarm volume control and alarm
acknowledge.
The APD-250M060 monitor is a DTE device and will operate
with a host that is either a DTE or DCE type device. Inter-
face is through standard DB25, RS-232D connectors.
