POWERING UP
Power up the 2050 system after the following has been
completed:
• The 1996R CPU has been installed.
• The 2050 Matrix Switching Bays have been installed (refer
to 2050 Switching Bays Installation Manual, OP2050).
• The Data Lines from the 1996R CPU are properly
connected (to Switching Bays, Code Generators, etc.).
• The RS-232 control lines from the 1996R CPU are properly
connected (to Alarm Interface Units, Keyboards, etc.).
• At least one camera has been connected for video input.
• At least one monitor has been connected for viewing video
output.
• All video and data lines have been properly terminated.
• At least one keyboard, or external computer, has been
connected to the 1996R CPU for system control.
Apply power to the equipment one bay at a time, ending with
the 1996R CPU. Refer to the installation manuals for each unit
for any requirements or restrictions on powering up that unit.
Powering the 1996R CPU
Connect the 1996R CPU line cord to the required power source
(see Power Sources, page 1-2). There is no power switch on
the 1996R, power is applied to the CPU when the line cord is
connected to the power source.
Five groups of green LEDs on the 1996R front panel (see
Figure 1-4, below) indicate CPU operating status.
• The POWER LEDs (the left-most group of four LEDs)
display power status (WXYZ = +5, -5, +9, and -9 VDC
respectively). All of these LEDs should illuminate when the
system is operating properly.
• The first group of DATA LEDs to the right of the POWER
display indicate CPU operating status. These four LEDs
(“F”, “E”, “D”, “C”) display a count of zero through nine, in
binary, at a rate of one count per second. Proper counting
indicates proper operation of the CPU.
• The three groups of DATA LEDs on the right (“B” through
“0”) display CPU error codes. If any of these LEDs are
steadily illuminated, the system must be serviced.
CPU Reset
Problems indicated by LEDs not operating as described above
may be resolved by performing a CPU Reset. CPU Reset is a
non-volatile system reset which affects the system hardware
only - no programming setups are lost.
To reset the CPU, press the RESET button on the front panel
and hold for a minimum of three seconds. The RESET button
is recessed inside the front panel hole to the left of the POWER
LEDs (see Figure 1-4).
If the CPU still does not properly operate, contact American
Dynamics for further assistance (see notice on below).
Operating System Verification
When calling American Dynamics for assistance, the revision
level of the 1996R CPU software may require verification. To
verify the 1996R operating system software, enter “70” on the
keyboard, then press the “F2” button.
NOTE: The keyboard keyswitch must be in the Program
(PROG) position for this function.
In response, a five-digit code, “UF3M
n ”, is shown in the
Status Line of the on-screen display (Figure 2-1, page 2-3).
The last digit of this display code is a number which identifies
the revision level of the 1996R CPU Operating System.
