DESCRIPTION
The PMC21A is a high-resolution color monitor that can be used in desktop applications or
rack mounted using the bezel rack mount that is provided as a standard accessory. The
rack mount is constructed of steel, has a black finish, and occupies 11 rack unit spaces. It is
supplied with eight flat-head screws to attach the rack mount to the monitor, and four 10-32
screws to attach the rack mount to a console.
The monitor supports NTSC and PAL video, as well as 120 VAC and 230 VAC input power.
An automatic switching system makes all the necessary changes for adapting to the required formats. Manual selection is not required. A separate power cord is supplied for each
voltage input.
INSTALLATION
CAUTION:
not install this
monitor in a
location having excessive
heat or in any way that
obstructs the ventilation
openings in the cabinet.
Premature component
failure or cabinet damage
may result.
NOTE:
Installation of the
monitor and rack mount into
the console may require two
persons.
Do
The PMC21A features audio input and output, and has a steel housing and front panel controls. The S-VHS high-resolution video (420 horizontal lines at center) and digital comb filter

3. Adjust the VOLUME control for the desired audio level. Turn the control clockwise to increase and counterclockwise to decrease.
4. Adjust the CONT. control for the desired overall contrast. Proper adjustment will allow
maximum gradations between the darkest and lightest picture contrast. Turn the control clockwise to increase and counterclockwise to decrease.
5. Adjust the BRIGHT control for the desired overall display brightness. This control is
also useful to compensate for differences in surrounding area lighting. Turn the control
clockwise to increase and counterclockwise to decrease.
6. Adjust the COLOR control to set the color saturation level. Turn the control clockwise
to increase and counterclockwise to decrease.
7. Adjust the SHARP control to obtain the clearest picture.
8. Adjust the TINT control for the proper color phase or flesh tones. When turned clockwise, the skin tone becomes greenish. When turned counterclockwise, skin tone becomes reddish.
PASSIVE LOOPING
Passive looping is accomplished when two or three monitors are connected in series (see
Figure 4) and a looping signal is sent through the IN and OUT connectors of one monitor
and to the next in series. Unless you want to view the monitor(s), none of them need to be
turned on for passive looping to function.
