Keyboard Video Selection
Note: Keyboard video selection is available from any AD
keyboard connected to the AD1650B. The keyboard
control functions described on the following pages (2-3 to
2-6) are restricted on certain keyboards. Refer to the
appropriate keyboard manual, and to the list of AD
keyboards in the Appendix, page A-9, for these restrictions.
System control functions are accessed from a keyboard by first
placing one of the monitors of the system under the control of
the keyboard (“Calling” a monitor to a keyboard) and then
“Calling” cameras in the system to that monitor.
To “Call” a Monitor to a Keyboard:
1. If keyboard has an ENTER display, press the CLEAR
button to clear the ENTER display.
2. Enter the number of the desired monitor on the keypad.
(The ENTER display shows the number entered.)
3. Press the MONITOR (MON) button on the keyboard. The
number of the MONITOR NOW UNDER CONTROL of the
keyboard is displayed in the MONITOR display.
To “Call” a Camera to the Monitor under Control:
1. If keyboard has an ENTER display, press the CLEAR
button to clear the ENTER display.
2. Enter the number of the desired camera on the keypad.
Note: A video source must be connected to this input.
3. Press the CAMERA (CAM) button on the keyboard. The
number of the CAMERA NOW ON THE MONITOR
UNDER CONTROL is displayed in the CAMERA display.
The selected camera video input is now switched to display on
the monitor under control.
When a camera is called to a monitor, an On-Screen Display is
included in the bottom two lines of the video picture, as
illustrated in Figure 2-1.
The Camera Number identifies the camera being viewed;
this is either the Real camera number, or the Pseudo number
if one is assigned (see Camera menu, page 4-18).
The 16-character, 2-line Camera Title is blank until a title
is entered for the camera (see Camera menu, page 4-19).
The Time and Date lines show the current system time and
date (see Time and Date menu, page 4-4).
The Status Line shows current information about the
camera being viewed (alarms, dwell times, etc.). A list of
the different Status Line displays is provided in the
Appendix, page A-8.
The orientation and contents of the on-screen display are
changed by the non-menu programming function, Monitor
Display Arrangement, page 3-3. Specific items of this display
can be turned on and off from the Monitor menu, page 4-16.
Adjustments to the on-screen display position and brightness
of each monitor are made with controls located on the
associated Video Output Module of the AD1650B switching
bay. Refer to the Video Output Module Setup procedures in
the AD1650B Switching System Installation manual,
OP1650B, for these adjustments.
